# CamSwapper: A Virtual Camera Module (Android 10+)
|
||||||
|
|
||||||
|
**PLEASE DO NOT USE THIS SOFTWARE FOR ILLEGAL PURPOSES.**
|
||||||
|
|
||||||
|
CamSwapper is a virtual camera module that replaces your device's camera feed with video files or images at the application level (via Xposed/LSPosed) or system-wide (via HAL hook).
|
||||||
|
|
||||||
|
## Quick Start
|
||||||
|
|
||||||
|
1. Install the CamSwapper APK on a rooted device with LSPosed
|
||||||
|
2. Enable module in LSPosed Manager and select target apps
|
||||||
|
3. Select a video file from the app UI
|
||||||
|
4. Open any hooked camera app — your video plays as the camera feed
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
|
||||||
|
- Android 10+ (API 29+)
|
||||||
|
- Root access
|
||||||
|
- LSPosed Framework 2.0.0+ (for app-level hook)
|
||||||
|
- Magisk or KernelSU (for system-wide HAL hook)
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
### Setup
|
||||||
|
1. Place video files in `DCIM`, `Movies`, or other public storage
|
||||||
|
2. Grant the module media read permissions
|
||||||
|
3. Grant target apps media read permissions
|
||||||
|
4. In LSPosed, enable CamSwapper and select target scope (TikTok, Telegram, etc.)
|
||||||
|
5. **Force stop** target app after any changes
|
||||||
|
6. Tap the thumbnail area to select a video file
|
||||||
|
|
||||||
|
### Debugging
|
||||||
|
Enable "Print Logs" in the app, then:
|
||||||
|
```bash
|
||||||
|
adb logcat | grep "VCX"
|
||||||
|
```
|
||||||
|
|
||||||
|
## System-Wide HAL Hook
|
||||||
|
|
||||||
|
For system-wide camera replacement (all apps at once), flash the module ZIP:
|
||||||
|
|
||||||
|
### Installation
|
||||||
|
```bash
|
||||||
|
# Flash camswapper-hal-hook-v1.zip in Magisk/KernelSU
|
||||||
|
adb reboot
|
||||||
|
|
||||||
|
# Configure
|
||||||
|
enabled=1
|
||||||
|
source_mode=file # or rtsp
|
||||||
|
video_path=/data/local/camera_magic/video.mp4
|
||||||
|
rtsp_url=rtsp://192.168.1.100:554/stream
|
||||||
|
```
|
||||||
|
|
||||||
|
### Verification
|
||||||
|
```bash
|
||||||
|
# Check hook loaded
|
||||||
|
adb shell getprop wrap.android.hardware.camera.provider@2.7-service-google
|
||||||
|
|
||||||
|
# Check logs
|
||||||
|
adb logcat -d -s CameraHook
|
||||||
|
```
|
||||||
|
|
||||||
|
### Uninstall
|
||||||
|
```bash
|
||||||
|
adb shell su -c "rm -rf /data/adb/modules/camera-hook"
|
||||||
|
adb shell su -c "setprop wrap.android.hardware.camera.provider@2.7-service-google ''"
|
||||||
|
adb shell su -c "rm -rf /data/local/camera_magic"
|
||||||
|
adb reboot
|
||||||
|
```
|
||||||
|
|
||||||
|
## Known Issues
|
||||||
|
|
||||||
|
- Green lines on video edges — Fixed
|
||||||
|
- Camera1 API not stopping threads after recording — Fixed
|
||||||
|
- Camera2 API hook on menu switch — Fixed
|
||||||
|
- 4K audio desync on older devices (runtime permission) — Toggle front/rear camera as workaround

# libcamera3.so - CamSwapper Native Library
|
||||||
|
|
||||||
|
## Status
|
||||||
|
Pre-compiled binary. **No source code available.**
|
||||||
|
|
||||||
|
## Location
|
||||||
|
`app/src/main/jniLibs/arm64-v8a/libcamera3.so`
|
||||||
|
|
||||||
|
## What it does
|
||||||
|
- Provides JNI functions called from `NativeBridge.kt`
|
||||||
|
- Decodes video using FFmpeg/libav (VideoDecoder class)
|
||||||
|
- Manages camera state (CameraState class)
|
||||||
|
- Overwrites preview buffers with video frames
|
||||||
|
|
||||||
|
## What it does NOT do
|
||||||
|
- Does NOT hook camera HAL directly
|
||||||
|
- Does NOT provide system-wide camera replacement alone
|
||||||
|
- Requires Java-level Xposed hooks to feed it surfaces
|
||||||
|
|
||||||
|
## Options to modify
|
||||||
|
1. **Reverse-engineer** the binary (very complex, not recommended)
|
||||||
|
2. **Reimplement** from scratch (requires C++, FFmpeg, Android NDK knowledge)
|
||||||
|
3. **Keep as-is** and use Java hooks (recommended - this is what currently works)
|
||||||
|
|
||||||
|
## Build (if source existed)
|
||||||
|
```bash
|
||||||
|
cd app/src/main/jni
|
||||||
|
$ANDROID_NDK_HOME/ndk-build
|
||||||
|
# or
|
||||||
|
cd app/src/main/jni
|
||||||
|
cmake . && make
|
||||||
|
```
|
||||||
|
|
||||||
|
## Current Architecture
|
||||||
|
```
|
||||||
|
Java Hooks (Camera2Hooker) → NativeBridge.registerSurface() → libcamera3.so
|
||||||
|
↓
|
||||||
|
VideoDecoder (decodes video)
|
||||||
|
↓
|
||||||
|
overwritePreviewBuffer() (overwrites camera buffers)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Recommendation
|
||||||
|
Keep the working Java hooking approach. The native library is a utility layer, not a HAL hooking solution.

# Buffer Sharing Design: Video → HAL
|
||||||
|
|
||||||
|
## Problem
|
||||||
|
|
||||||
|
We need to inject decoded video frames into the camera HAL's output buffer pipeline at the HAL process level (camera provider APEX), replacing real camera frames with virtual video frames.
|
||||||
|
|
||||||
|
## Architecture Context
|
||||||
|
|
||||||
|
```
|
||||||
|
[App Process] [Camera Provider APEX Process]
|
||||||
|
┌─────────────────┐ ┌──────────────────────────────────┐
|
||||||
|
│ ExoPlayer │ │ libgooglecamerahal.so │
|
||||||
|
│ ↓ decodes │ │ ↓ processCaptureRequest() │
|
||||||
|
│ MediaCodec │ │ ↓ fills output buffers │
|
||||||
|
│ ↓ YUV frames │ │ ↓ (AHardwareBuffer/gralloc) │
|
||||||
|
│ VirtualCamera │ │ cameraserver reads via binder │
|
||||||
|
│ Renderer │ └──────────────────────────────────┘
|
||||||
|
│ ↓ renders to │ ↑
|
||||||
|
│ Surface │ │ WE INJECT HERE
|
||||||
|
└─────────────────┘ ┌──────────────────────────────────┘
|
||||||
|
│ libcamera_hook.so (LD_PRELOAD) │
|
||||||
|
│ intercepts processCaptureRequest │
|
||||||
|
└──────────────────────────────────┘
|
||||||
|
```
|
||||||
|
|
||||||
|
## Evaluated Approaches
|
||||||
|
|
||||||
|
### 1. AHardwareBuffer Direct Write (CHOSEN)
|
||||||
|
|
||||||
|
**How it works**: HAL output buffers are `buffer_handle_t` backed by gralloc/AHardwareBuffer. Lock the buffer for CPU write, copy YUV frame data, unlock.
|
||||||
|
|
||||||
|
**Pros**:
|
||||||
|
- No extra memory allocation needed (reuse HAL's buffer)
|
||||||
|
- Direct write to the buffer cameraserver will read
|
||||||
|
- Works with YUV_420_888 (format 32) which is CPU-accessible
|
||||||
|
- Pixel 9a (API 36) fully supports AHardwareBuffer_lock()
|
||||||
|
|
||||||
|
**Cons**:
|
||||||
|
- CPU copy required (not zero-copy)
|
||||||
|
- IMPLEMENTATION_DEFINED (format 35) buffers may not be CPU-lockable
|
||||||
|
- Must handle buffer stride/alignment correctly
|
||||||
|
|
||||||
|
**Verdict**: **CHOSEN** for YUV_420_888 preview streams. This is the primary virtual camera use case.
|
||||||
|
|
||||||
|
### 2. Shared Memory (ashmem/memfd) Cross-Process
|
||||||
|
|
||||||
|
**How it works**: App process decodes video, writes YUV frames to shared memory. Provider process reads from shared memory and copies into HAL buffers.
|
||||||
|
|
||||||
|
**Pros**:
|
||||||
|
- Clean separation: decoder in app, injection in provider
|
||||||
|
- App has full MediaCodec/ExoPlayer access
|
||||||
|
- memfd_create() available on Android 11+ (API 30+)
|
||||||
|
|
||||||
|
**Cons**:
|
||||||
|
- Extra copy: decoder → shared memory → HAL buffer
|
||||||
|
- Cross-process synchronization complexity
|
||||||
|
- Need IPC mechanism (binder, socket, or signal)
|
||||||
|
|
||||||
|
**Verdict**: **CHOSEN** as the transport mechanism from app to provider process. Combined with Approach 1 for the final write.
|
||||||
|
|
||||||
|
### 3. ION/dmabuf
|
||||||
|
|
||||||
|
**How it works**: Allocate ION memory, pass dmabuf fd to both decoder and HAL.
|
||||||
|
|
||||||
|
**Pros**:
|
||||||
|
- Zero-copy potential
|
||||||
|
- GPU/ISP accessible
|
||||||
|
|
||||||
|
**Cons**:
|
||||||
|
- Vendor-specific ION heap configurations
|
||||||
|
- Requires /dev/ion access (SELinux restrictions in provider process)
|
||||||
|
- Complex buffer lifecycle management
|
||||||
|
- Overkill for our use case
|
||||||
|
|
||||||
|
**Verdict**: **REJECTED**. Too complex, vendor-dependent, and SELinux-hostile.

## Chosen Architecture
|
||||||
|
|
||||||
|
### Two-Stage Pipeline
|
||||||
|
|
||||||
|
```
|
||||||
|
Stage 1: App Process (Video Decoding)
|
||||||
|
┌─────────────────────────────────────┐
|
||||||
|
│ ExoPlayer → MediaCodec │
|
||||||
|
│ ↓ decoded YUV420 frames │
|
||||||
|
│ FrameRingBuffer (shared memory) │
|
||||||
|
│ ↓ memfd + mmap │
|
||||||
|
│ SharedMemoryWriter │
|
||||||
|
└─────────────────────────────────────┘
|
||||||
|
│
|
||||||
|
│ memfd (fd passed via binder/property)
|
||||||
|
↓
|
||||||
|
Stage 2: Provider Process (HAL Injection)
|
||||||
|
┌─────────────────────────────────────┐
|
||||||
|
│ SharedMemoryReader │
|
||||||
|
│ ↓ reads latest YUV frame │
|
||||||
|
│ BufferConverter │
|
||||||
|
│ ↓ handles format/stride conversion │
|
||||||
|
│ AHardwareBufferWriter │
|
||||||
|
│ ↓ lock → memcpy → unlock │
|
||||||
|
│ HAL output buffer (to cameraserver) │
|
||||||
|
└─────────────────────────────────────┘
|
||||||
|
```
|
||||||
|
|
||||||
|
### Buffer Lifecycle
|
||||||
|
|
||||||
|
1. **Allocation**: HAL allocates output buffers during `configureStreams()`. We observe and record buffer dimensions, format, and stride.
|
||||||
|
|
||||||
|
2. **Frame Production**: App process decodes video via MediaCodec, writes YUV frames to a ring buffer in shared memory (memfd). Each frame has a sequence number and timestamp.
|
||||||
|
|
||||||
|
3. **Frame Consumption**: In `processCaptureRequest()`, our hook:
|
||||||
|
a. Reads the latest frame from shared memory
|
||||||
|
b. Locks the HAL output buffer via `AHardwareBuffer_lock()` (for YUV_420_888)
|
||||||
|
c. Copies frame data with stride conversion if needed
|
||||||
|
d. Unlocks the buffer
|
||||||
|
e. Returns to cameraserver (appears as real camera frame)
|
||||||
|
|
||||||
|
4. **Synchronization**:
|
||||||
|
- Shared memory ring buffer uses atomic sequence numbers
|
||||||
|
- Reader always grabs the latest complete frame (no blocking)
|
||||||
|
- If no frame available, forward to real HAL (passthrough)
|
||||||
|
|
||||||
|
### Format Handling
|
||||||
|
|
||||||
|
| Stream Format | Strategy |
|
||||||
|
|---|---|
|
||||||
|
| YUV_420_888 (32) | Direct AHardwareBuffer_lock + memcpy |
|
||||||
|
| IMPLEMENTATION_DEFINED (35) | Passthrough to real HAL (opaque GPU format) |
|
||||||
|
| JPEG/BLOB (37) | Passthrough to real HAL (encode handled by HAL) |
|
||||||
|
|
||||||
|
### Memory Layout
|
||||||
|
|
||||||
|
Shared memory ring buffer (memfd):
|
||||||
|
```
|
||||||
|
┌─────────────────────────────────────────────┐
|
||||||
|
│ Header (256 bytes) │
|
||||||
|
│ - magic: 0xCSWAPR00 │
|
||||||
|
│ - frame_count: uint32 │
|
||||||
|
│ - write_index: atomic<uint32> │
|
||||||
|
│ - read_index: atomic<uint32> │
|
||||||
|
│ - frame_width: uint32 │
|
||||||
|
│ - frame_height: uint32 │
|
||||||
|
│ - frame_size: uint32 │
|
||||||
|
├─────────────────────────────────────────────┤
|
||||||
|
│ Frame 0 (width × height × 3/2 bytes) │
|
||||||
|
│ - Y plane: width × height │
|
||||||
|
│ - U plane: width/2 × height/2 │
|
||||||
|
│ - V plane: width/2 × height/2 │
|
||||||
|
├─────────────────────────────────────────────┤
|
||||||
|
│ Frame 1 ... │
|
||||||
|
├─────────────────────────────────────────────┤
|
||||||
|
│ Frame N-1 ... │
|
||||||
|
└─────────────────────────────────────────────┘
|
||||||
|
```
|
||||||
|
|
||||||
|
Ring size: 4 frames (enough for 30fps video with slight timing jitter).
|
||||||
|
|
||||||
|
### AHardwareBuffer Write Procedure
|
||||||
|
|
||||||
|
```cpp
|
||||||
|
// In processCaptureRequest hook:
|
||||||
|
for (int i = 0; i < request->output_buffer_count; i++) {
|
||||||
|
auto& buf = request->output_buffers[i];
|
||||||
|
auto stream = find_stream(buf.stream_id);
|
||||||
|
|
||||||
|
if (stream->format == FORMAT_YUV_420_888 && g_hook_state.virtual_camera_enabled) {
|
||||||
|
// Lock buffer for CPU write
|
||||||
|
AHardwareBuffer* ahb = AHardwareBuffer_fromNativeHandle(buf.handle);
|
||||||
|
AHardwareBuffer_Desc desc;
|
||||||
|
AHardwareBuffer_describe(ahb, &desc);
|
||||||
|
|
||||||
|
void* cpu_addr = nullptr;
|
||||||
|
int result = AHardwareBuffer_lock(ahb,
|
||||||
|
AHARDWAREBUFFER_USAGE_CPU_WRITE_OFTEN,
|
||||||
|
-1, nullptr, &cpu_addr);
|
||||||
|
|
||||||
|
if (result == 0 && cpu_addr) {
|
||||||
|
// Copy YUV frame from shared memory
|
||||||
|
copy_yuv_frame_to_buffer(cpu_addr, desc.stride, desc.height,
|
||||||
|
g_frame_reader->latest_frame());
|
||||||
|
AHardwareBuffer_unlock(ahb, nullptr);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```

## 1. Architecture Overview
|
||||||
|
|
||||||
|
### CRITICAL DISCOVERY: Camera HAL is a Separate Process
|
||||||
|
|
||||||
|
The Pixel 9a camera HAL is **NOT** a shared library loaded by `system_server`. It is a **separate process** running as the `system` user, communicating with `cameraserver` via **AIDL Binder IPC**.
|
||||||
|
|
||||||
|
```
|
||||||
|
┌─────────────────────────────────────────────────────────────┐
|
||||||
|
│ App Process │
|
||||||
|
│ (Google Camera, Fossify Camera, Instagram, etc.) │

### Implications for HAL Hooking
|
||||||
|
|
||||||
|
The traditional "HAL wrapper library loaded by system_server" approach is **WRONG** for Pixel 9a. The correct interception strategies are:
|
||||||
|
|
||||||
|
1. **Hook the camera provider process** — Inject a library into the provider process via `wrap.` property + `LD_PRELOAD`
|
||||||
|
2. **Intercept Binder/AIDL IPC** — Hook the Binder communication between `cameraserver` and the provider
|
||||||
|
3. **Replace the APEX binary** — Swap the provider binary with a wrapper (requires APEX modification)
|
||||||
|
4. **Hook at cameraserver level** — Intercept in `cameraserver` before requests reach the provider
|
||||||
|
|
||||||
|
**Recommended approach**: Option 1 (hook the camera provider process via `wrap.` property). The provider process is the most direct interception point.

## 2. AIDL Interface Hierarchy
|
||||||
|
|
||||||
|
### Interface Chain
|
||||||
|
|
||||||
|
```
|
||||||
|
ICameraProvider (v3)
|
||||||
|
└── getCameraIdList() → ["device@1.1/internal/0", ...]
|
||||||
|
└── openCamera(deviceId, callback) → ICameraDevice
|
||||||
|
└── ICameraDevice (v4)
|
||||||
|
└── open(sessionCallback) → ICameraDeviceSession
|
||||||
|
└── ICameraDeviceSession (v4)
|
||||||
|
├── configureStreams(config) → StreamConfiguration
|
||||||
|
├── processCaptureRequest(request) → Status
|
||||||
|
├── flush() → Status
|
||||||
|
└── close()
|
||||||
|
```
|
||||||
|
|
||||||
|
### Key AIDL Interfaces
|
||||||
|
|
||||||
|
#### ICameraProvider (android.hardware.camera.provider-V4-ndk.so)
|
||||||
|
|
||||||
|
```aidl
|
||||||
|
interface ICameraProvider {
|
||||||
|
CameraStatus[] getCameraIdList(out String[] cameraIds);
|
||||||
|
CameraStatus isSetTorchModeSupported(String cameraId, out boolean support);
|
||||||
|
CameraStatus openCamera(String cameraId, ICameraDeviceCallback callback,
|
||||||
|
out ICameraDevice device);
|
||||||
|
CameraStatus setTorchMode(String cameraId, boolean enabled);
|
||||||
|
CameraStatus notifyDeviceStateChange(long physicalCameraId, long deviceState);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
#### ICameraDevice (android.hardware.camera.device-V4-ndk.so)
|
||||||
|
|
||||||
|
```aidl
|
||||||
|
interface ICameraDevice {
|
||||||
|
CameraMetadata getCameraCharacteristics();
|
||||||
|
int getResourceCost();
|
||||||
|
CameraStatus open(ICameraDeviceCallback callback,
|
||||||
|
out ICameraDeviceSession session);
|
||||||
|
void close();
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
#### ICameraDeviceSession — PRIMARY INTERCEPTION TARGET
|
||||||
|
|
||||||
|
```aidl
|
||||||
|
interface ICameraDeviceSession {
|
||||||
|
// ★★★ KEY FUNCTION 1 ★★★
|
||||||
|
// Configure output/input streams for the camera
|
||||||
|
CameraStatus configureStreams(
|
||||||
|
in StreamConfiguration requestedConfiguration,
|
||||||
|
out HalStreamConfiguration halConfiguration);
|
||||||
|
|
||||||
|
// ★★★ KEY FUNCTION 2 ★★★
|
||||||
|
// Process a capture request — THIS IS WHERE WE REPLACE FRAMES
|
||||||
|
CameraStatus processCaptureRequest(
|
||||||
|
in CaptureRequest request,
|
||||||
|
out CaptureResultMetadata resultMetadata);
|
||||||
|
|
||||||
|
// ★★★ KEY FUNCTION 3 ★★★
|
||||||
|
CameraStatus flush();
|
||||||
|
|
||||||
|
void close();
|
||||||
|
CameraStatus getSignalStreamMap(out SignalStreamMap streamMap);
|
||||||
|
CameraStatus processPhysicalCaptureRequest(
|
||||||
|
in PhysicalCaptureRequestInfo physicalRequestInfo,
|
||||||
|
out CaptureResultMetadata resultMetadata);
|
||||||
|
CameraStatus setRepeatingRequests(in CaptureRequest[] requests, out int32_t sequenceId);
|
||||||
|
CameraStatus cancelRepeatingRequest(int32_t sequenceId);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||

## 3. Camera Device Configuration
|
||||||
|
|
||||||
|
### Device Mapping
|
||||||
|
|
||||||
|
| API Device | HAL ID | Facing | Description |
|
||||||
|
|---|---|---|---|
|
||||||
|
| Device 0 | HAL 2 (Rear) | Back | Main rear camera |
|
||||||
|
| Device 0 | HAL 3 (RearWide) | Back | Ultra-wide rear camera |
|
||||||
|
| Device 1 | HAL 1 (Front) | Front | Selfie camera |
|
||||||
|
|
||||||
|
### Stream Configuration Formats
|
||||||
|
|
||||||
|
From `android.scaler.availableStreamConfigurations`:
|
||||||
|
|
||||||
|
| Format Code | Format Name | Description | Max Resolution |
|
||||||
|
|---|---|---|---|
|
||||||
|
| 32 | `HAL_PIXEL_FORMAT_YCBCR_420_888` | Flexible YUV 4:2:0 | 4000×3000 |
|
||||||
|
| 35 | `HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED` | GPU/ISP opaque format | 4208×3120 |
|
||||||
|
| 36 | `HAL_PIXEL_FORMAT_RAW16` | Raw sensor data | Varies |
|
||||||
|
| 37 | `HAL_PIXEL_FORMAT_BLOB` (JPEG) | Compressed JPEG | 4000×3000 |
|
||||||
|
|
||||||
|
**Most important format for virtual camera**: Format 32 (YUV_420_888) — this is what preview streams use and what we need to feed video frames into.
|
||||||
|
|
||||||
|
### Buffer Flow
|
||||||
|
|
||||||
|
```
|
||||||
|
1. App calls CameraDevice.createCaptureSession() with Surface targets
|
||||||
|
2. cameraserver calls ICameraDeviceSession.configureStreams()
|
||||||
|
→ HAL allocates/configures output buffers
|
||||||
|
3. App calls CaptureRequest.Builder.addTarget(surface)
|
||||||
|
4. cameraserver calls ICameraDeviceSession.processCaptureRequest()
|
||||||
|
→ HAL fills buffers with camera sensor data
|
||||||
|
→ Buffers are returned to cameraserver → app surfaces
|
||||||
|
```
|
||||||
|
|
||||||
|
**Our interception point**: Step 4 — replace buffer contents with decoded video frames BEFORE returning to cameraserver.

||||||

## 5. Interception Strategy
|
||||||
|
|
||||||
|
### Approach: Hook the Camera Provider Process
|
||||||
|
|
||||||
|
Since the camera HAL runs as a separate process, we inject our hooking library into that process.
|
||||||
|
|
||||||
|
#### Option A: wrap. Property + LD_PRELOAD (Recommended)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Set via Magisk service.sh at boot:
|
||||||
|
setprop wrap.android.hardware.camera.provider@2.7-service-google \
|
||||||
|
"LD_PRELOAD=/data/local/camera_magic/libcamera_hook.so"
|
||||||
|
```
|
||||||
|
|
||||||
|
The `wrap.` property tells Android's init to restart the process with LD_PRELOAD.
|
||||||
|
|
||||||
|
#### Option B: Replace APEX Binary
|
||||||
|
|
||||||
|
Replace the provider binary with a wrapper that loads the original + our hooks. More invasive but more reliable.
|
||||||
|
|
||||||
|
### Functions to Hook
|
||||||
|
|
||||||
|
| Function | Library | Purpose | Hook Strategy |
|
||||||
|
|---|---|---|---|
|
||||||
|
| `configureStreams` | `libgooglecamerahal.so` | Know stream sizes/formats | Observe and store config |
|
||||||
|
| `processCaptureRequest` | `libgooglecamerahal.so` | Replace frames | Fill buffers with video data |
|
||||||
|
| `flush` | `libgooglecamerahal.so` | Cleanup | Pass through + cleanup our buffers |
|
||||||
|
|
||||||
|
### Buffer Replacement Flow
|
||||||
|
|
||||||
|
```
|
||||||
|
1. configureStreams() called → store stream config (resolution, format, buffer count)
|
||||||
|
2. Allocate our own video frame buffers (matching HAL format)
|
||||||
|
3. processCaptureRequest() called:
|
||||||
|
a. Check if virtual camera is enabled (/data/local/camera_magic/config.txt)
|
||||||
|
b. If enabled: copy decoded video frame into request's output buffer
|
||||||
|
c. If disabled: pass through to original HAL
|
||||||
|
d. Return OK status
|
||||||
|
4. cameraserver receives buffer → sends to app → app shows virtual video
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 6. SELinux Considerations
|
||||||
|
|
||||||
|
The camera provider process runs as `system` user with its own SELinux context. Injecting libraries requires:
|
||||||
|
|
||||||
|
1. SELinux policy allowing `system` process to load libraries from `/data/local/`
|
||||||
|
2. Magisk `sepolicy.rule` to add:
|
||||||
|
```
|
||||||
|
allow hal_camera_server system_data_file:file { read open execute };
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 7. Verification Commands
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Verify camera provider process
|
||||||
|
adb shell ps -A | grep camera.provider

# CamSwapper System-Wide HAL Hook Testing Tutorial
|
||||||
|
|
||||||
|
This guide walks you through testing the system-wide camera HAL hook feature on a rooted Pixel 9a. This mode injects virtual camera feeds into all camera apps simultaneously via LD_PRELOAD, with no per-app Xposed scoping required.
|

- Rooted Pixel 9a (Magisk or KernelSU installed)
|
||||||
|
- ADB (Android Debug Bridge) set up on your computer
|
||||||
|
- `camswapper-hal-hook-v1.zip` — the flashable module ZIP (pre-built, in the repo)
|
||||||
|
- A test video file (MP4, H.264/H.265/VP9) or RTSP stream URL
|
||||||
|
|
||||||
|
## Step 1: Prepare the Device
|
||||||
|
|
||||||
|
1. Connect your Pixel 9a via USB
|
||||||
|
2. Enable USB debugging in Developer Options
|
||||||
|
3. Authorize the ADB connection on your device
|
||||||
|
4. Verify ADB connection:
|
||||||
|
```bash
|
||||||
|
adb devices
|
||||||
|
```
|
||||||
|
You should see your device serial with "device" status.
|
||||||
|
|
||||||
|
5. Verify root access:
|
||||||
|
```bash
|
||||||
|
adb shell su -c id
|
||||||
|
```
|
||||||
|
Should return `uid=0(root) gid=0(root) groups=0(root)`.
|
||||||
|
|
||||||
|
## Step 2: Install the Module (ZIP Flash)
|
||||||
|
|
||||||
|
The module is packaged as a standard ZIP file that can be flashed directly in Magisk or KernelSU.
|
||||||
|
|
||||||
|
### Option A: Flash via Magisk App
|
||||||
|
1. Transfer `camswapper-hal-hook-v1.zip` to your device
|
||||||
|
2. Open Magisk app → Modules tab → "Install from storage"
|
||||||
|
3. Select `camswapper-hal-hook-v1.zip`
|
||||||
|
4. Wait for installation to complete
|
||||||
|
5. Tap "Reboot"
|
||||||
|
|
||||||
|
### Option B: Flash via KernelSU Manager
|
||||||
|
1. Transfer `camswapper-hal-hook-v1.zip` to your device
|
||||||
|
2. Open KernelSU app → Modules tab → "+" button
|
||||||
|
3. Select `camswapper-hal-hook-v1.zip`
|
||||||
|
4. Wait for installation to complete
|
||||||
|
5. Tap "Reboot"
|
||||||
|
|
||||||
|
### Option C: Flash via Custom Recovery (TWRP)
|
||||||
|
1. Push the ZIP to your device: `adb push camswapper-hal-hook-v1.zip /sdcard/`
|
||||||
|
2. Boot into recovery
|
||||||
|
3. Flash the ZIP
|
||||||
|
4. Reboot system
|
||||||
|
|
||||||
|
### Verify Installation
|
||||||
|
After reboot, check the module is recognized:
|
||||||
|
```bash
|
||||||
|
adb shell su -c "ls -la /data/adb/modules/camera-hook/"
|
||||||
|
```
|
||||||
|
You should see `module.prop`, `post-fs-data.sh`, `service.sh`, `libcamera_hook.so`, `system.prop`, `sepolicy.rule`, and `customize.sh`.
|
||||||
|
|
||||||
|
## Step 3: Verify Module Installation
|
||||||
|
|
||||||
|
After the device reboots, run the included integration test script or verify manually.
|
||||||
|
|
||||||
|
### Option A: Run Integration Test Script
|
||||||
|
```bash
|
||||||
|
./test_hal_wrapper.sh
|
||||||
|
```
|
||||||
|
This script checks prerequisites, module installation, wrap property, config file, and hook loading status.
|
||||||
|
|
||||||
|
### Option B: Manual Verification
|
||||||
|
|
||||||
|
1. Check the wrap property is set correctly:
|
||||||
|
```bash
|
||||||
|
adb shell getprop wrap.android.hardware.camera.provider@2.7-service-google
|
||||||
|
```
|
||||||
|
Expected output: `LD_PRELOAD=/data/adb/modules/camera-hook/libcamera_hook.so`
|
||||||
|
|
||||||
|
2. Check the camera provider process is running:
|
||||||
|
```bash
|
||||||
|
adb shell pidof android.hardware.camera.provider@2.7-service-google
|
||||||
|
```
|
||||||
|
Should return a PID number.
|
||||||
|
|
||||||
|
3. Verify `libcamera_hook.so` is loaded in the provider process:
|
||||||
|
```bash
|
||||||
|
adb shell su -c "cat /proc/\$(pidof android.hardware.camera.provider@2.7-service-google)/maps | grep libcamera_hook"
|
||||||
|
```
|
||||||
|
Should show the path to `libcamera_hook.so`.
|
||||||
|
|
||||||
|
4. Check hook initialization logs:
|
||||||
|
```bash
|
||||||
|
adb logcat -d -s CameraHook
|
||||||
|
```
|
||||||
|
Should show hook initialization messages.
|
||||||
|
|
||||||
|
5. Check for SELinux denials:
|
||||||
|
```bash
|
||||||
|
adb shell su -c "dmesg | grep \"avc: denied\" | grep camera"
|
||||||
|
```
|
||||||
|
Should return empty if no denials are present.
|
||||||
|
|
||||||
|
## Step 4: Configure Video Source
|
||||||
|
|
||||||
|
The HAL hook reads configuration from `/data/local/camera_magic/config.txt`. You can configure it via the CamSwapper app or manually.
|
||||||
|
|
||||||
|
### Option A: Use CamSwapper App
|
||||||
|
|
||||||
|
1. Install the CamSwapper app on your device
|
||||||
|
2. Open the app and navigate to HAL Mode settings
|
||||||
|
3. Toggle "Enable HAL Mode"
|
||||||
|
4. Select source mode: File or RTSP
|
||||||
|
5. For File mode: select your video file (place it in `/data/local/camera_magic/video.mp4` or update config manually)
|
||||||
|
6. For RTSP mode: enter your RTSP stream URL
|
||||||
|
|
||||||
|
### Option B: Manual Config File
|
||||||
|
|
||||||
|
Create or edit the config file directly via adb:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
adb shell su -c "mkdir -p /data/local/camera_magic"
|
||||||
|
adb shell su -c "echo 'enabled=1' > /data/local/camera_magic/config.txt"
|
||||||
|
adb shell su -c "echo 'source_mode=file' >> /data/local/camera_magic/config.txt"
|
||||||
|
adb shell su -c "echo 'video_path=/data/local/camera_magic/test_video.mp4' >> /data/local/camera_magic/config.txt"
|
||||||
|
adb shell su -c "echo 'rtsp_url=' >> /data/local/camera_magic/config.txt"
|
||||||
|
adb shell su -c "chmod 644 /data/local/camera_magic/config.txt"
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Config File Format
|
||||||
|
```
|
||||||
|
enabled=1 # 0=off, 1=on
|
||||||
|
source_mode=file # file or rtsp
|
||||||
|
video_path=/data/local/camera_magic/video.mp4
|
||||||
|
rtsp_url=rtsp://192.168.1.100:554/stream
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 5: Test the Virtual Camera
|
||||||
|
|
||||||
|
1. Push your test video file to the device:
|
||||||
|
```bash
|
||||||
|
adb push test_video.mp4 /data/local/camera_magic/video.mp4
|
||||||
|
adb shell su -c "chmod 644 /data/local/camera_magic/video.mp4"
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Open any camera app (Google Camera, Instagram, Telegram, etc.)
|
||||||
|
|
||||||
|
3. The camera preview should display your virtual video instead of the real camera feed.
|
||||||
|
|
||||||
|
4. Check hook logs for frame injection:
|
||||||
|
```bash
|
||||||
|
adb logcat -s CameraHook
|
||||||
|
```
|
||||||
|
Should show FPS counts and frame injection messages.
|
||||||
|
|
||||||
|
## Step 6: Test RTSP Stream (Optional)
|
||||||
|
|
||||||
|
1. Update config to RTSP mode:
|
||||||
|
```bash
|
||||||
|
adb shell su -c "sed -i 's/source_mode=file/source_mode=rtsp/' /data/local/camera_magic/config.txt"
|
||||||
|
adb shell su -c "sed -i 's|video_path=.*|rtsp_url=rtsp://YOUR_RTSP_URL|' /data/local/camera_magic/config.txt"
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Restart the camera provider process to reload config:
|
||||||
|
```bash
|
||||||
|
adb shell su -c "killall android.hardware.camera.provider@2.7-service-google"
|
||||||
|
```
|
||||||
|
The process will restart automatically and load the new config.
|
||||||
|
|
||||||
|
3. Open a camera app to view the RTSP stream.
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Hook Not Loading
|
||||||
|
- Verify module is in `/data/adb/modules/camera-hook/`
|
||||||
|
- Check wrap property is set correctly
|
||||||
|
- Reboot the device
|
||||||
|
- Check `adb shell dmesg | grep CameraHook` for error messages
|
||||||
|
|
||||||
|
### No Virtual Feed Showing
|
||||||
|
- Verify `enabled=1` in config file
|
||||||
|
- Check video file path is correct and accessible
|
||||||
|
- Test RTSP URL with VLC first to ensure it's reachable
|
||||||
|
- View hook logs: `adb logcat -s CameraHook`
|
||||||
|
- Verify `libcamera_hook.so` is loaded in the provider process
|
||||||
|
|
||||||
|
### SELinux Denials
|
||||||
|
- Check `adb shell dmesg | grep "avc: denied"`
|
||||||
|
- Ensure `sepolicy.rule` is present in the module directory
|
||||||
|
- Temporary test: set SELinux to Permissive with `adb shell su -c setenforce 0`
|
||||||
|
|
||||||
|
### Camera App Crashes
|
||||||
|
- Check logcat for crashes: `adb logcat -d | grep -i crash`
|
||||||
|
- Verify video format is supported (H.264/H.265/VP9)
|
||||||
|
- Try a lower resolution/bitrate video file
|
||||||
|
|
||||||
|
## Uninstall/Disable HAL Hook
|
||||||
|
|
||||||
|
### Temporary Disable
|
||||||
|
Set `enabled=0` in config file:
|
||||||
|
```bash
|
||||||
|
adb shell su -c "sed -i 's/enabled=1/enabled=0/' /data/local/camera_magic/config.txt"
|
||||||
|
```
|
||||||
|
Restart camera provider: `adb shell su -c "killall android.hardware.camera.provider@2.7-service-google"`
|
||||||
|
|
||||||
|
### Permanent Uninstall
|
||||||
|
```bash
|
||||||
|
adb shell su -c "rm -rf /data/adb/modules/camera-hook"
|
||||||
|
adb shell su -c "setprop wrap.android.hardware.camera.provider@2.7-service-google ''"
|
||||||
|
adb shell su -c "rm -rf /data/local/camera_magic"
|
||||||
|
adb reboot
|
||||||
|
```

# Important for running:

#
|

|
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
|

|
# noncompliant, but you have some other compliant shell such as ksh or
|
||||||
|
# bash, then to run this script, type that shell name before the whole

|
||||||
|
#
|
||||||
|
# ksh Gradle
|
||||||
|
#
|
||||||
|
# Busybox and similar reduced shells will NOT work, because this script
|

|
# requires all of these POSIX shell features:
|
||||||
|
# * functions;
|
||||||
|
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
|
||||||
|
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
|
||||||
|
# * compound commands having a testable exit status, especially «case»;
|

|
# * various built-in commands including «command», «set», and «ulimit».

|
#
|

|
# Important for patching:
|

|
#
|

|
# (2) This script targets any POSIX shell, so it avoids extensions provided

|
||||||
|
#
|
||||||
|
# The "traditional" practice of packing multiple parameters into a
