MediaMetadataRetriever setDataSource failed : status = 0xFFFFFFED
22 février 2016, par darjaI need to fetch frames from video located in the web. That’s how I do this :
class PlayerWrapper {
private static final MediaMetadataRetriever mMediaMetadataRetriever = new MediaMetadataRetriever();
…
public void initPlayback(final Context context, final VideoSurfaceView videoSurface, final String url) {
new Thread(new Runnable() {
@Override
public void run() {
…
try {
mMediaMetadataRetriever.setDataSource(url, new HashMap());
} catch (Exception e) {
DPLog(e);
}
}
}).start();
}
public Bitmap getFrameAt(int positionMillis) {
if (mMediaMetadataRetriever != null) {
DPLog.d("Creating frame for position [%s]", positionMillis);
try {
return mMediaMetadataRetriever.getFrameAtTime(positionMillis * 1000);
} catch (Exception e) {
…
return null;
}
} else {
return null;
}
}
}This works fine on several devices with Android 4.4, 5 and 6. But on one device with Android 4.1.2
setDataSource
function fails with following stack trace :java.lang.RuntimeException: setDataSource failed: status = 0xFFFFFFED

Url is got from YouTube API, looks like this :

Why this can happen and what to do ?
I also tried to use
FFmpegMediaMetadataRetriever
with the same logic, but it doesn’t work at all,setDataSource
causes exceptions with status0xFFFFFFFF
on all devices. As I found on SO, that means that url is invalid, but it is ok and played byMediaPlayer
without any issues. Also I found that ffmpeg has issues with urls longer than 1024, but that’s not my case too.May be there are another way to get frames from video ?

libavfilter/vf_dnn_detect : Add yolo support
21 novembre 2023, par Wenbin Chenlibavfilter/vf_dnn_detect : Add yolo support
Add yolo support. Yolo model doesn't output final result. It outputs
candidate boxes, so we need post-process to remove overlap boxes to
get final results. Also, the box's coordinators relate to cell and
anchors, so we need these information to calculate boxes as well.Model detail please refer to : https://github.com/openvinotoolkit/open_model_zoo/tree/master/models/public/yolo-v2-tf
