实现 IAndroidIO，播放闪退

定义回调：类 FileAndroidIO.java

public class FileAndroidIO implements IAndroidIO {

private static String TAG = "ANDROID_IO_TRACE";
private RandomAccessFile file;

public FileAndroidIO() {
}

@Override
public int open(String url) throws IOException {
    Log.i(TAG, "open , url = " + url);

    this.file = new RandomAccessFile(new File(url), "r");
    return 1;
}

@Override
public int read(byte[] buffer, int size) throws IOException {
    int read = file.read(buffer, 0, size);

    Log.i(TAG, "read , size=" + size + " , bufferLength = " + buffer.length + " , read=" + read);
    return read;
}

@Override
public long seek(long offset, int whence) throws IOException {
    Log.i(TAG, "seek , offset=" + offset + ", whence=" + whence);

    file.seek(offset);
    return file.getFilePointer();
}

@Override
public int close() throws IOException {
    Log.i(TAG, "close");

    file.close();
    file = null;
    return 1;
}

}

设置回调：类 IjkVideoView.java private void openVideo() {

    if (mUri == null || mSurfaceHolder == null) {
        // not ready for playback just yet, will try again later
        return;
    }
    // we shouldn't clear the target state, because somebody might have
    // called start() previously
    release(false);

    AudioManager am = (AudioManager) mAppContext.getSystemService(Context.AUDIO_SERVICE);
    am.requestAudioFocus(null, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN);

    try {
        mMediaPlayer = createPlayer(mSettings.getPlayer());

        // TODO: create SubtitleController in MediaPlayer, but we need
        // a context for the subtitle renderers
        final Context context = getContext();
        // REMOVED: SubtitleController

        // REMOVED: mAudioSession
        mMediaPlayer.setOnPreparedListener(mPreparedListener);
        mMediaPlayer.setOnVideoSizeChangedListener(mSizeChangedListener);
        mMediaPlayer.setOnCompletionListener(mCompletionListener);
        mMediaPlayer.setOnErrorListener(mErrorListener);
        mMediaPlayer.setOnInfoListener(mInfoListener);
        mMediaPlayer.setOnBufferingUpdateListener(mBufferingUpdateListener);
        mMediaPlayer.setOnSeekCompleteListener(mSeekCompleteListener);
        mMediaPlayer.setOnTimedTextListener(mOnTimedTextListener);
        mCurrentBufferPercentage = 0;
       //-------------------------修改-------------------------
        ((IjkMediaPlayer) mMediaPlayer).setAndroidIOCallback(new FileAndroidIO());
        // mUri = Uri.parse("ijkio:httphook:" + mUri.toString());
        mUri = Uri.parse("ijkio:androidio:" + mUri.toString());
       //-------------------------修改-------------------------
        String scheme = mUri.getScheme();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M &&
                mSettings.getUsingMediaDataSource() &&
                (TextUtils.isEmpty(scheme) || scheme.equalsIgnoreCase("file"))) {
            IMediaDataSource dataSource = new FileMediaDataSource(new File(mUri.toString()));
            mMediaPlayer.setDataSource(dataSource);
        } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
            mMediaPlayer.setDataSource(mAppContext, mUri, mHeaders);
        } else {
            mMediaPlayer.setDataSource(mUri.toString());
        }
        bindSurfaceHolder(mMediaPlayer, mSurfaceHolder);
        mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
        mMediaPlayer.setScreenOnWhilePlaying(true);
        mPrepareStartTime = System.currentTimeMillis();
        mMediaPlayer.prepareAsync();
        if (mHudViewHolder != null)
            mHudViewHolder.setMediaPlayer(mMediaPlayer);

        // REMOVED: mPendingSubtitleTracks

        // we don't set the target state here either, but preserve the
        // target state that was there before.
        mCurrentState = STATE_PREPARING;
        attachMediaController();
    } catch (IOException ex) {
        Log.w(TAG, "Unable to open content: " + mUri, ex);
        mCurrentState = STATE_ERROR;
        mTargetState = STATE_ERROR;
        mErrorListener.onError(mMediaPlayer, MediaPlayer.MEDIA_ERROR_UNKNOWN, 0);
    } catch (IllegalArgumentException ex) {
        Log.w(TAG, "Unable to open content: " + mUri, ex);
        mCurrentState = STATE_ERROR;
        mTargetState = STATE_ERROR;
        mErrorListener.onError(mMediaPlayer, MediaPlayer.MEDIA_ERROR_UNKNOWN, 0);
    } finally {
        // REMOVED: mPendingSubtitleTracks.clear();
    }
}

@raymond1012 这是我的修改有错敬请指正～

我也定义了 FileAndroidIO.java，并且在 ijkVideoView.java 中 setAndroidIOCallback。但是播放视频的时候就闪退了，报错如下： 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example V/IJKMEDIA: setDataSource: path ijkio:androidio:/storage/emulated/0/Movies/SD2019-05-06-10-13-32.mp4 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example D/IJKMEDIA: ijkmp_set_data_source(url="ijkio:androidio:/storage/emulated/0/Movies/SD2019-05-06-10-13-32.mp4") 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example D/IJKMEDIA: ijkmp_set_data_source(url="ijkio:androidio:/storage/emulated/0/Movies/SD2019-05-06-10-13-32.mp4")=0 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example D/IJKMEDIA: IjkMediaPlayer_setVideoSurface 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example D/IJKMEDIA: ijkmp_set_android_surface(surface=0x7ff5000628) 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example D/IJKMEDIA: ffpipeline_set_surface() 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example D/IJKMEDIA: ijkmp_set_android_surface(surface=0x7ff5000628)=void 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example D/IJKMEDIA: IjkMediaPlayer_prepareAsync 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example D/IJKMEDIA: ijkmp_prepare_async() 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: ===== versions ===== 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: ijkplayer : k0.8.8 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: FFmpeg : ff3.4--ijk0.8.7--20180103--001 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: libavutil : 55.78.100 08-21 17:49:48.950 20596-20659/tv.danmaku.ijk.media.example I/IJKMEDIA: SDL_RunThread: [20659] ff_msg_loop 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: libavcodec : 57.107.100 08-21 17:49:48.950 20596-20659/tv.danmaku.ijk.media.example D/IJKMEDIA: message_loop 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: libavformat : 57.83.100 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: libswscale : 4.8.100 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: libswresample: 2.9.100 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: ===== options ===== 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: player-opts : mediacodec = 0 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: player-opts : opensles = 0 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: player-opts : overlay-format = 842225234 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: player-opts : framedrop = 1 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: player-opts : start-on-prepared = 0 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: format-opts : ijkapplication = 367467380576 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: format-opts : ijkiomanager = 367467380736 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: format-opts : http-detect-range-support = 0 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: format-opts : androidio-inject-callback = 1049930 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: codec-opts : skip_loop_filter = 48 08-21 17:49:48.950 20596-20596/tv.danmaku.ijk.media.example I/IJKMEDIA: =================== 08-21 17:49:48.951 20596-20659/tv.danmaku.ijk.media.example D/IJKMEDIA: FFP_MSG_FLUSH: 08-21 17:49:48.952 20596-20596/tv.danmaku.ijk.media.example D/IJKMEDIA: ijkmp_prepare_async()=0 08-21 17:49:48.952 20596-20660/tv.danmaku.ijk.media.example I/IJKMEDIA: SDL_RunThread: [20660] ff_vout 08-21 17:49:48.952 20596-20661/tv.danmaku.ijk.media.example I/IJKMEDIA: SDL_RunThread: [20661] ff_read 08-21 17:49:48.952 20596-20661/tv.danmaku.ijk.media.example D/IJKMEDIA: Opening 'ijkio:androidio:/storage/emulated/0/Movies/SD2019-05-06-10-13-32.mp4' for reading 08-21 17:49:48.952 20596-20661/tv.danmaku.ijk.media.example D/IJKMEDIA: AVOption type 127 of option async not implemented yet
