react-native-video ^6.0.0-alpha.3 "errorCode": "24001" in some mkv videos

Question

I am developing an app capable of playing an IPTV list. All the contents go with the mkv format and most of them play correctly but some return the following error:

{
  "error": Object {
    "errorCode": "24001",
    "errorException": "com.google.android.exoplayer2.ExoPlaybackException: MediaCodecVideoRenderer error, index=0, format=Format(1, null, null, video/x-unknown, null, -1, und, [720, 304, -1.0], [-1, -1]), format_supported=NO_UNSUPPORTED_TYPE",
    "errorStackTrace": "com.google.android.exoplayer2.ExoPlaybackException: MediaCodecVideoRenderer error, index=0, format=Format(1, null, null, video/x-unknown, null, -1, und, [720, 304, -1.0], [-1, -1]), format_supported=NO_UNSUPPORTED_TYPE

",
    "errorString": "ExoPlaybackException: ERROR_CODE_DECODER_INIT_FAILED",
  },
}

This is the code I use with the react-native-video library:

<Video
        key={keyload}
        ref={(ref) => {setVideo(ref)}}
        style={styles.video}
        onLoad={(data) => setMetadata(data)}//
        source={{
          uri: uriLoad, initOptions: ['--codec=avcodec']
        }}
        onProgress={progress => {setProgress(progress.currentTime)}}
        controls={false}
        fullscreen={true}
        paused={paused}
        volume={volumen}
        fullscreenAutorotate={true}
        selectedVideoTrack={videoTrack}
        selectedAudioTrack={audioTrack}
        selectedTextTrack={textTrack}
        resizeMode={resizemode}
        onEnd={() => end()}
        isLooping 
        onError={error => playerError(error)}
        onPlaybackStatusUpdat
        allowsExternalPlayback
        e={status => setStatus(() => status)}//setStatus(() => status)
    />

  },
  "devDependencies": {
    "@babel/core": "^7.12.9"
  },
  "private": true
}

I have tried with different versions of the library and with different buffer configurations, but nothing works. Does anyone know why this error occurs and how to fix it? Thanks.

Answer 1

Do probably you need to try a different codec list? Because the error code is about a decoding problem https://exoplayer.dev/doc/reference/com/google/android/exoplayer2/PlaybackException.html#ERROR_CODE_DECODER_INIT_FAILED

public static final int ERROR_CODE_DECODER_INIT_FAILED

// Caused by a decoder initialization failure.
