• How to play encrypted video in exoplayer (android app) coming from HLS streamer ?

  2 février 2021, par Harshil Makwana

  I am right now using FFMPEG to stream mp4 file using HLS.
I am using this link to enable encryption : https://hlsbook.net/how-to-encrypt-hls-video-with-ffmpeg/

  


  To play video in my android app, I am using exoplayer, below is my source code to play video :

  


  Player player;
private MediaSource buildMediaSource(Uri uri) {
     TrackSelection.Factory adaptiveTrackSelection = new AdaptiveTrackSelection.Factory(new DefaultBandwidthMeter());
    player = ExoPlayerFactory.newSimpleInstance(
            this,
            new DefaultTrackSelector(adaptiveTrackSelection));
    playerView.setPlayer(player);
    // These factories are used to construct two media sources.
    DefaultBandwidthMeter defaultBandwidthMeter = DefaultBandwidthMeter.getSingletonInstance(this);
    DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(mContext,
            Util.getUserAgent(mContext, "cookvid"), defaultBandwidthMeter);
    //DataSource.Factory dataSourceFactory =
    //        new DefaultDataSourceFactory(this, "exoplayer-codelab");

    HlsMediaSource.Factory mediaSourceFactory = new HlsMediaSource.Factory(dataSourceFactory);
    return mediaSourceFactory.createMediaSource(uri);
    //return new ProgressiveMediaSource.Factory(dataSourceFactory)
     //       .createMediaSource(uri);
}
private void initializePlayer() {
    Uri uri = Uri.parse(getString(R.string.media_url_hls));
    MediaSource mediaSource = buildMediaSource(uri);
    player.setPlayWhenReady(playWhenReady);
    player.seekTo(currentWindow, playbackPosition);
    player.addListener(playbackStateListener);
    player.prepare(mediaSource, false, false);
}


  


  But with this code, I can not play video in app, If I am not using this encryption ,then exoplayer can play video without any issue.

  


  Please help me on this, I am newbie on exoplayer side.

  


• Is there any way to play video other then .mp4 on Android in Kivy ?

  11 décembre 2016, par Gerasimov Mikhail

  While I didn’t find this in docs, currently only way to play video on Android in Kivy is to use ffmpeg. Am I right ?

  Even so looks like default ffmpeg recipe supports only .mp4 videos. Is there any way to make it work with .avi and other popular video formats ?
