android capture video frame
I need to get a frame of a video file (it may be on sdcard, cache dir or app dir). I have package android.media in my application and inside I have class MediaMetadataRetriever. To get first frame into a bitmap, I use code:
public static Bitmap getVideoFrame(Context context, Uri videoUri) {
MediaMetadataRetriever retriever = new MediaMetadataRetriever();
try {
retriever.setMode(MediaMetadataRetriever.MODE_CAPTURE_FRAME_ONLY);
retriever.setDataSource(context, videoUri);
return retriever.captureFrame();
} catch (IllegalArgumentException ex) {
throw new RuntimeException();
} catch (RuntimeException ex) {
throw new RuntimeException();
} finally {
retriever.release();
}
}
But this it's not working. It throws an exception (java.lang.RuntimeException: setDataSource failed: status = 0x80000000) when I set data source. Do you know how to make this code to work? Or Do you have any similar (simple) solution without using ffmpeg or other external libraries? videoUri is a valid uri (media player can play video from that URI)
The following works for me:
public static Bitmap getVideoFrame(FileDescriptor FD) {
MediaMetadataRetriever retriever = new MediaMetadataRetriever();
try {
retriever.setDataSource(FD);
return retriever.getFrameAtTime();
} catch (IllegalArgumentException ex) {
ex.printStackTrace();
} catch (RuntimeException ex) {
ex.printStackTrace();
} finally {
try {
retriever.release();
} catch (RuntimeException ex) {
}
}
return null;
}
Also works if you use a path instead of a filedescriptor.
Try this, I've used it and its working
public static Bitmap getVideoFrame(Context context, Uri uri) {
MediaMetadataRetriever retriever = new MediaMetadataRetriever();
try {
retriever.setDataSource(uri.toString(),new HashMap<String, String>());
return retriever.getFrameAtTime();
} catch (IllegalArgumentException ex) {
ex.printStackTrace();
} catch (RuntimeException ex) {
ex.printStackTrace();
} finally {
try {
retriever.release();
} catch (RuntimeException ex) {
}
}
return null;
}
In place of uri you can directly pass your url .
