Overview
Since Andropid SDK build 1.1.0.26 it is possible to use custom software camera implementation to capture video. To do this:
1. Develop Java class implementing CameraVideoCapturer interface
2. Import the following modules to application
import org.webrtc.CameraVideoCapturer; import com.flashphoner.fpwcsapi.camera.CameraCapturerFactory; import com.flashphoner.fpwcsapi.camera.CustomCameraCapturerOptions; import com.flashphoner.fpwcsapi.camera.CustomCameras;
3. Prepare CustomCameraCapturerOptions object
private CustomCameraCapturerOptions createCustomCameraCapturerOptions() {
return new CustomCameraCapturerOptions() {
private String cameraName;
private CameraVideoCapturer.CameraEventsHandler eventsHandler;
private boolean captureToTexture;
@Override
public Class<?>[] getCameraConstructorArgsTypes() {
return new Class<?>[]{String.class, CameraVideoCapturer.CameraEventsHandler.class, boolean.class};
}
@Override
public Object[] getCameraConstructorArgs() {
return new Object[]{cameraName, eventsHandler, captureToTexture};
}
@Override
public void setCameraName(String cameraName) {
this.cameraName = cameraName;
}
@Override
public void setEventsHandler(CameraVideoCapturer.CameraEventsHandler eventsHandler) {
this.eventsHandler = eventsHandler;
}
@Override
public void setCaptureToTexture(boolean captureToTexture) {
this.captureToTexture = captureToTexture;
}
// Use your custom capturer class name here
@Override
public String getCameraClassName() {
return your.custom.CameraCapturer;
}
@Override
public Class<?>[] getEnumeratorConstructorArgsTypes() {
return new Class[0];
}
@Override
public Object[] getEnumeratorConstructorArgs() {
return new Object[0];
}
// Use your custom capturer enumerator name here
@Override
public String getEnumeratorClassName() {
return your.custom.CameraEnumerator;
}
};
}
4. Choose custom camera in application before stream publishsing
CameraCapturerFactory.getInstance().setCustomCameraCapturerOptions(createCustomCameraCapturerOptions());
CameraCapturerFactory.getInstance().setCameraType(CameraCapturerFactory.CameraType.CUSTOM);
Usage example
Using CameraVideoCapturer implementation to access a flashlight
1. CustomCameraCapturerOptions object creation
private CustomCameraCapturerOptions createCustomCameraCapturerOptions() {
return new CustomCameraCapturerOptions() {
private String cameraName;
private CameraVideoCapturer.CameraEventsHandler eventsHandler;
private boolean captureToTexture;
@Override
public Class<?>[] getCameraConstructorArgsTypes() {
return new Class<?>[]{String.class, CameraVideoCapturer.CameraEventsHandler.class, boolean.class};
}
@Override
public Object[] getCameraConstructorArgs() {
return new Object[]{cameraName, eventsHandler, captureToTexture};
}
@Override
public void setCameraName(String cameraName) {
this.cameraName = cameraName;
}
@Override
public void setEventsHandler(CameraVideoCapturer.CameraEventsHandler eventsHandler) {
this.eventsHandler = eventsHandler;
}
@Override
public void setCaptureToTexture(boolean captureToTexture) {
this.captureToTexture = captureToTexture;
}
// Using org.webrtc.FlashlightCameraCapturer to access flashlight hidden controls.
@Override
public String getCameraClassName() {
return CustomCameras.FLASHLIGHT_CAMERA_CAPTURER;
}
@Override
public Class<?>[] getEnumeratorConstructorArgsTypes() {
return new Class[0];
}
@Override
public Object[] getEnumeratorConstructorArgs() {
return new Object[0];
}
// Using org.webrtc.FlashlightCameraEnumerator to access flashlight hidden controls.
@Override
public String getEnumeratorClassName() {
return CustomCameras.FLASHLIGHT_CAMERA_ENUMERATOR;
}
};
}
2. Camera choosing
CameraCapturerFactory.getInstance().setCustomCameraCapturerOptions(createCustomCameraCapturerOptions());
mCameraCapturer = (LabelledSpinner) findViewById(R.id.camera_capturer);
mCameraCapturer.setOnItemChosenListener(new LabelledSpinner.OnItemChosenListener() {
@Override
public void onItemChosen(View labelledSpinner, AdapterView<?> adapterView, View itemView, int position, long id) {
String captureType = getResources().getStringArray(R.array.camera_capturer)[position];
switch (captureType) {
case "flashlight":
CameraCapturerFactory.getInstance().setCameraType(CameraCapturerFactory.CameraType.FLASHLIGHT_CAMERA);
break;
case "camera1capturer":
CameraCapturerFactory.getInstance().setCameraType(CameraCapturerFactory.CameraType.CAMERA1CAPTURE);
break;
case "camera2capturer":
CameraCapturerFactory.getInstance().setCameraType(CameraCapturerFactory.CameraType.CAMERA2CAPTURE);
break;
case "custom":
CameraCapturerFactory.getInstance().setCameraType(CameraCapturerFactory.CameraType.CUSTOM);
break;
}
mCameraSpinner.setItemsArray(Flashphoner.getMediaDevices().getVideoList());
}
@Override
public void onNothingChosen(View labelledSpinner, AdapterView<?> adapterView) {
}
});
