请问为什么 SurfaceView 可以播放视频而 GLSurfaceView 不可以

public class MySurfaceView extends GLSurfaceView implements SurfaceHolder.Callback2 {

private IMediaPlayer mIjkMediaPlayer; public MySurfaceVew(Context context) { this(context,null); } public MySurfaceView(Context context, AttributeSet attrs) { super(context, attrs); this.getHolder().addCallback(this); } @Override public void surfaceRedrawNeeded(@NonNull SurfaceHolder holder) { } @Override public void surfaceCreated(@NonNull SurfaceHolder holder) { IjkMediaPlayer.loadLibrariesOnce(null); mIjkMediaPlayer = new IjkMediaPlayer(); IjkMediaPlayer.native_setLogLevel(IjkMediaPlayer.IJK_LOG_DEBUG); ((IjkMediaPlayer)mIjkMediaPlayer).setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "mediacodec", 1); ((IjkMediaPlayer)mIjkMediaPlayer).setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "start-on-prepared", 1); MyLog.printLog("当前类:MySurfaceView,当前方法：surfaceCreated,当前线程:"+ Thread.currentThread().getName()+",信息:"); try { mIjkMediaPlayer.setDataSource("http://v26-web.douyinvod.com/9bc1da753b72cf58198a5ac6b33f5c5f/642ac71d/video/tos/cn/tos-cn-ve-15c001-alinc2/oUnw3NQsIhdSv2DA3DyAnzwBEUZhDDkNgAnfce/?a=6383&ch=26&cr=3&dr=0&lr=all&cd=0%7C0%7C0%7C3&cv=1&br=4099&bt=4099&cs=0&ds=4&ft=bvTKJbQQqUYqfJEZao0OW_EklpPiXkHIzMVJERXpwrbPD-I&mime_type=video_mp4&qs=0&rc=Ozs7Nmk5aDs6Njs1OWVkNEBpM3c7cmc6ZnJpajMzNGkzM0A0Ml4yLjMzX2AxNGNeNi8vYSNqM15ncjQwa2dgLS1kLTBzcw%3D%3D&l=20230403193118DD1B97F459BD1305F3B1&btag=8000&testst=1680521484498"); } catch (IOException e) { } mIjkMediaPlayer.setDisplay(holder); mIjkMediaPlayer.prepareAsync(); ((IjkMediaPlayer)mIjkMediaPlayer).setOnAllListener(new IMediaPlayer.OnAllListener() { @Override public void onPrepared(IMediaPlayer iMediaPlayer) { } @Override public void onCompletion(IMediaPlayer iMediaPlayer) { } @Override public void onBufferingUpdate(IMediaPlayer iMediaPlayer, int i) { } @Override public void onSeekComplete(IMediaPlayer iMediaPlayer) { } @Override public void onVideoSizeChanged(IMediaPlayer iMediaPlayer, int width, int height, int i2, int i3) { ConstraintLayout.LayoutParams layoutParams = new ConstraintLayout.LayoutParams(MySurfaceView.this.getLayoutParams()); layoutParams.height = iMediaPlayer.getVideoHeight(); layoutParams.width = iMediaPlayer.getVideoWidth(); requestLayout(); } @Override public void onError(IMediaPlayer iMediaPlayer, int i, int i1) { } @Override public void onInfo(IMediaPlayer iMediaPlayer, int i, int i1) { } @Override public void onTimedText(IMediaPlayer iMediaPlayer, IjkTimedText ijkTimedText) { } @Override public void onServerCmd(IMediaPlayer iMediaPlayer, IjkServerCmd ijkServerCmd) { } }); } @Override public void surfaceChanged(@NonNull SurfaceHolder holder, int format, int width, int height) { } @Override public void surfaceDestroyed(@NonNull SurfaceHolder holder) { } }
