How to play multiple videos in list view using MediaPlayer?

Question

I am trying to implement a list view with a video as its elements. I use this project to display video by texture. It uses MediaPlayer from below. It does not work (most of the time) when downloading two videos at the same time.

The error I get is:

TextureVideoView error. File or network related operation errors. MediaPlayer: error (1, -2147479551) 

and this also happens when a file is loaded from disk

In terms of error handling, I tried resetting the URL. Then I basically get

 E/BufferQueueProducer: [unnamed-30578-12] disconnect(P): connected to another API (cur=0 req=3) 

mistake. It’s not clear to me that installing some videos from the Internet will work, but trying again to skip the same URL will fail.

So, in OnErrorListener:

 textureView.setVideo(item.getUriMp4(),MediaFensterPlayerController.DEFAULT_VIDEO_START); 

will fail, but:

 textureView.setVideo("http://different.video" ... ) 

will work great.

This is also not a problem with a specific file, as it will crash when scrolling through various video files. Sometimes those that don't work will work the next time, etc.

I also tried using a combination of MediaCodec and MediaExtractor instead of the MediaPlayer approach, but I came across what it looks like, a specific device platform error

any clues? any suggestions?

thanks

Answer 1

You can try this instead of the library. It is extracted from an example using Google on github:

It simultaneously decodes two video streams into two TextureView modes.

One of the key features is that video decoders do not stop when activity is restarted due to a change in orientation. This should simulate the playback of the video stream in real time. If an action is paused because it is “completed” (indicating that we are leaving the action for a non-trivial amount of time), the video decoders are turned off.

TODO: Consider turning off when you turn off the screen to save battery.

Java:

DoubleDecodeActivity.java

 public class DoubleDecodeActivity extends Activity { private static final String TAG = MainActivity.TAG; private static final int VIDEO_COUNT = 2; //How many videos to play simultaneously. // Must be static storage so they'll survive Activity restart. private static boolean sVideoRunning = false; private static VideoBlob[] sBlob = new VideoBlob[VIDEO_COUNT]; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_double_decode); if (!sVideoRunning) { sBlob[0] = new VideoBlob((TextureView) findViewById(R.id.double1_texture_view), ContentManager.MOVIE_SLIDERS, 0); sBlob[1] = new VideoBlob((TextureView) findViewById(R.id.double2_texture_view), ContentManager.MOVIE_EIGHT_RECTS, 1); sVideoRunning = true; } else { sBlob[0].recreateView((TextureView) findViewById(R.id.double1_texture_view)); sBlob[1].recreateView((TextureView) findViewById(R.id.double2_texture_view)); } } @Override protected void onPause() { super.onPause(); boolean finishing = isFinishing(); Log.d(TAG, "isFinishing: " + finishing); for (int i = 0; i < VIDEO_COUNT; i++) { if (finishing) { sBlob[i].stopPlayback(); sBlob[i] = null; } } sVideoRunning = !finishing; Log.d(TAG, "onPause complete"); } /** * Video playback blob. * <p> * Encapsulates the video decoder and playback surface. * <p> * We want to avoid tearing down and recreating the video decoder on orientation changes, * because it can be expensive to do so.

Answer 2

Add all your paths to the video in an array or ArrayList and implement mediaplayer.setOnMediaPlayerCompletionListener when the media is playing, then this interface will be called from here, initialize a new instance of the media player, providing a new media and calling start ()

I just tell you the logic, I hope this works

Answer 3

Use VideoView instead of ListView, it can work. Take a look here http://developer.android.com/reference/android/widget/VideoView.html

Current solution: I recommend JavaCV / OpenCV for playing multiple Java videos at the same time. It supports highlighting formats.

Tutorial - http://ganeshtiwaridotcomdotnp.blogspot.co.nz/search/label/OpenCV-JavaCV

JavaFX can also play some .MP4 video formats.

Old solution: - Despite the fact that JMF can play several videos at once, it is outdated and is no longer supported.
