I've been using grafika's MoviePlayer and bigFlake's ExtractMpegFramesTest to implement a seeking and extract frame feature in our app. These work fine for most of our user, however some of them encounter a IllegalStateException
on MediaCodec.configure
when setting up the ExtractMpegFramesTest
(this happens on Samsung Galaxy S4 mini, Samsung Galaxy J7, Samsung Galaxy A5, Huawei Ascend G7). The relevant code is as the following:
MoviePlayer
public void prepareResources() throws IOException {
// The MediaExtractor error messages aren't very useful. Check to see if the input
// file exists so we can throw a better one if it's not there.
if (!mSourceFile.canRead()) {
throw new FileNotFoundException("Unable to read " + mSourceFile);
}
try {
mExtractor = new MediaExtractor();
mExtractor.setDataSource(mSourceFile.toString());
mTrackIndex = selectTrack(mExtractor);
if (mTrackIndex < 0) {
throw new RuntimeException("No video track found in " + mSourceFile);
}
mExtractor.selectTrack(mTrackIndex);
MediaFormat format = mExtractor.getTrackFormat(mTrackIndex);
// Create a MediaCodec decoder, and configure it with the MediaFormat from the
// extractor. It's very important to use the format from the extractor because
// it contains a copy of the CSD-0/CSD-1 codec-specific data chunks.
String mime = format.getString(MediaFormat.KEY_MIME);
mDecoder = MediaCodec.createDecoderByType(mime);
mDecoder.configure(format, mOutputSurface, null, 0);
mDecoder.start();
mDecoderInputBuffers = mDecoder.getInputBuffers();
} catch (Exception e) {
e.printStackTrace();
}
}
ExtractMpegFramesTest
private void extractMpegFrames() throws IOException {
MediaCodec decoder = null;
CodecOutputSurface outputSurface = null;
MediaExtractor extractor = null;
/*int saveWidth = 640;
int saveHeight = 480;*/
try {
long start1 = System.currentTimeMillis();
File inputFile = new File(mInputVideoPath); // must be an absolute path
// The MediaExtractor error messages aren't very useful. Check to see if the input
// file exists so we can throw a better one if it's not there.
if (!inputFile.canRead()) {
throw new FileNotFoundException("Unable to read " + inputFile);
}
extractor = new MediaExtractor();
extractor.setDataSource(inputFile.toString());
int trackIndex = selectTrack(extractor);
if (trackIndex < 0) {
throw new RuntimeException("No video track found in " + inputFile);
}
extractor.selectTrack(trackIndex);
MediaFormat format = extractor.getTrackFormat(trackIndex);
if (VERBOSE) {
Log.d(TAG, "Video size is " + format.getInteger(MediaFormat.KEY_WIDTH) + "x" +
format.getInteger(MediaFormat.KEY_HEIGHT));
}
// Could use width/height from the MediaFormat to get full-size frames.
outputSurface = new CodecOutputSurface(format.getInteger(MediaFormat.KEY_WIDTH), format.getInteger(MediaFormat.KEY_HEIGHT));
// Create a MediaCodec decoder, and configure it with the MediaFormat from the
// extractor. It's very important to use the format from the extractor because
// it contains a copy of the CSD-0/CSD-1 codec-specific data chunks.
String mime = format.getString(MediaFormat.KEY_MIME);
decoder = MediaCodec.createDecoderByType(mime);
decoder.configure(format, outputSurface.getSurface(), null, 0); //fails right here
decoder.start();
long end1 = System.currentTimeMillis();
Timber.d("extractMpegFrames(): FRAME_EXTRACT setup in: %d millis", (end1-start1));
long start2 = System.currentTimeMillis();
doExtract(extractor, trackIndex, decoder, outputSurface);
long end2 = System.currentTimeMillis();
Timber.d("extractMpegFrames(): FRAME_EXTRACT doExtract in: %d millis", (end2-start2));
} finally {
// release everything we grabbed
if (outputSurface != null) {
outputSurface.release();
outputSurface = null;
}
if (decoder != null) {
decoder.stop();
decoder.release();
decoder = null;
}
if (extractor != null) {
extractor.release();
extractor = null;
}
}
}
I'm aware of this question, however what I don't understand is why MediaCodec
can be configured OK in MoviePlayer
(the video runs just fine) but it fails in ExtractMpegFramesTest
. At first, I think the device has some issues with the OpenGL set up, but it turn out to be MediaCodec problem.
Any insight would be greatly appreciated.
EDIT: After obtaining a Galaxy S4 mini testing device, I've been able to get a much more helpful log:

These are the codec info retrieved from devices having this problem:
OMX.qcom.video.encoder.avc
OMX.SEC.avc.enc
OMX.Exynos.AVC.Encoder
The strange thing is the Galaxy S4 mini can handle 720p videos just fine, it's just having problem with 1080p videos.
Ok, here to answer my own question again:
Firstly, why I can't extract frame with
ExtractMpegFramesTest
after usingMoviePlayer
to display videos:It appears that some devices can't handle 2 instances of
MediaCodec
at the same time for high res videos (>720p in the case of the Galaxy S4 mini) so you have to properly release one instance ofMediaCodec
before starting the other one, something like this:Secondly, why the
MoviePlayer
fails to configure for 1080p videos. In my case, since I start this activity from a media picker activity with aVideoView
for preview which has aMediaPlayer.OnErrorListener()
registered to detect faulty video. The problem is theonError()
callback has some really weird behavior on the Galaxy S4 mini while it work perfectly fine on my development devices. My wild guess thisMediaPlayer.OnErrorListener()
leaves theMediaCodec
in a bad state that cause a lot of headache later on.So the solution is to set a blank
OnErrorListener()
and properly release theVideoView
before doing anything else withMediaCodec
. Something like this:This explain a lot of weird thing that happen on different devices. I hope this help someone else debug their app.
