I have tried 1.5 video API. I could not make it work.It even can't do
preview.
following is my code:
private boolean initializeVideo() {
Log.v(TAG, "initializeVideo");
if(Common.mRecordedVideo!=null && Common.mRecordedVideo.exists())
Common.mRecordedVideo.delete();
File sDir = Environment.getExternalStorageDirectory();
String baseDir = sDir + Common.BASE_DIR;
File sampleDir=new File(baseDir);
if(!sampleDir.canWrite()) // Workaround for broken sdcard
support on the device.
sampleDir = new File("/sdcard/sdcard");
try
{
Common.mRecordedVideo = File.createTempFile(PREFIX,
EXTENSION, sampleDir);
}
catch(IOException e)
{
AlertDialog.Builder ab = new AlertDialog.Builder
(VideoRecord.this);
ab.setTitle("Error");
ab.setMessage(" can't write audio data to storage");
ab.setIcon(R.drawable.error);
ab.setNeutralButton("Close", new
DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int
whichButton)
{
}
});
ab.show();
return false;
}
Intent intent = getIntent();
releaseMediaRecorder();
if (mSurfaceHolder == null) {
Log.v(TAG, "SurfaceHolder is null");
return false;
}
mMediaRecorder = new MediaRecorder();
mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mMediaRecorder.setVideoSource
(MediaRecorder.VideoSource.CAMERA);
mMediaRecorder.setOutputFormat
(MediaRecorder.OutputFormat.THREE_GPP);
mMediaRecorder.setMaxDuration(MAX_RECORDING_DURATION_MS);
mMediaRecorder.setOutputFile
(Common.mRecordedVideo.getAbsolutePath());
// Use the same frame rate for both, since internally
// if the frame rate is too large, it can cause camera to
become
// unstable. We need to fix the MediaRecorder to disable the
support
// of setting frame rate for now.
mMediaRecorder.setVideoFrameRate(20);
mMediaRecorder.setVideoSize(352,288);
mMediaRecorder.setVideoEncoder
(MediaRecorder.VideoEncoder.H263);
mMediaRecorder.setPreviewDisplay(mSurfaceHolder.getSurface());
try {
mMediaRecorder.prepare();
} catch (IOException exception) {
Log.e(TAG, "prepare failed for " );
releaseMediaRecorder();
// TODO: add more exception handling logic here
return false;
}
mMediaRecorderRecording = false;
return true;
}
private void startVideoRecording() {
Log.v(TAG, "startVideoRecording");
if (!mMediaRecorderRecording)
{
// Check mMediaRecorder to see whether it is initialized or
not.
if (mMediaRecorder == null && initializeVideo() ==
false )
{
Log.e(TAG, "Initialize video (MediaRecorder)
failed.");
return;
}
try
{
mMediaRecorder.setOnErrorListener(this);
mMediaRecorder.setOnInfoListener(this);
mMediaRecorder.start(); // Recording is now started
} catch (RuntimeException e) {
Log.e(TAG, "Could not start media recorder. ", e);
return;
}
mMediaRecorderRecording = true;
mRecordingStartTime = SystemClock.uptimeMillis();
updateRecordingIndicator(true);
mRecordingTimeView.setText("");
mRecordingTimeView.setVisibility(View.VISIBLE);
mHandler.sendEmptyMessage(UPDATE_RECORD_TIME);
setScreenTimeoutInfinite();
}
}
