I'm a new android developer. I have done an Activity with a photo camera to take photos in a surface view but now I'm thinking to add a botton in the Activity to switch the camera to video recorder in the same surface view. This is possible?
Thanks in Advance.
I have the solution to my own question. I did a surface view and an Activity for a photo camera after I thought put a button to record a video in the same Activity with the same surface view but I don´t know if it was possible. Well, I wrote this method in the Activity to prepare de MediaRecorder and take the surface view.
public Boolean prepararCamaraVideo(){
mMediaRecorder = new MediaRecorder();
mCamera.unlock();
mMediaRecorder.setCamera(mCamera);
mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
state = MediaRecorderState.INITIALIZED;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.FROYO)
mMediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));
else {
mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
}
state = MediaRecorderState.DATA_SOURCE_CONFIGURED;
mOutputFile = Files.getExternalMediaFile(Files.MEDIA_TYPE_VIDEO).toString();
mMediaRecorder.setOutputFile(mOutputFile);
mMediaRecorder.setPreviewDisplay(mCameraPreview.getHolder().getSurface());
try {
mMediaRecorder.prepare();
} catch (IllegalStateException e) {
Log.d("Video", "IllegalStateException preparing MediaRecorder: " + e.getMessage());
releaseMediaRecorder();
return false;
} catch (IOException e) {
Log.d("Video", "IOException preparing MediaRecorder: " + e.getMessage());
releaseMediaRecorder();
return false;
}
return true;
}
This command mMediaRecorder.setPreviewDisplay(mCameraPreview.getHolder().getSurface()); get the surface for the Video Camera.
Finally the method to Record the video.
public void grabaVideo(View v) {
if (state!=MediaRecorderState.RECORDING){
if (prepararCamaraVideo()) {
mMediaRecorder.start();
state = MediaRecorderState.RECORDING;
Toast.makeText(getApplicationContext(), getString(R.string.capturing_video), Toast.LENGTH_SHORT).show();
} else {
// prepare didn't work, release the camera
releaseMediaRecorder();
// inform user
}
}
else{
mMediaRecorder.stop(); // stop the recording
releaseMediaRecorder(); // release the MediaRecorder object
mCamera.lock(); // take camera access back from MediaRecorder
state = MediaRecorderState.INITIAL;
Toast.makeText(getApplicationContext(), getString(R.string.video_stored_in) + " " + mOutputFile, Toast.LENGTH_SHORT).show();
}
}
I hope to help you if you need.
