报错
call to OpenGL ES API with no current context 
//opengls api执行的线程不对

Stop() called but track is not started or stopped


java.lang.NullPointerException: Can't toast on a thread that has not called Looper.prepare()
https://blog.csdn.net/chenzhengfeng/article/details/125540755
两种解决方法：
1. ooper.prepare();
   Toast.makeText(context, "测试", Toast.LENGTH_SHORT).show();
   Looper.loop();
2. runOnUiThread(new Runnable() {

   @Override
   public void run() {
   Toast.makeText(context, "测试", Toast.LENGTH_SHORT).show();
   }
   });

有部分机型可以，有部分机型不可以！

                    //mPreviewWdith:1920  mPreviewHeight:1080  * 3/2 == 3110400
                    //1920 * 1080 *3 /2 = 3110400
                    //2088960
                    //outData length:3110400, bufferInfo.size :3133440
                    //                    if (bufferInfo.size == outData.length) {
                    if (outputBuffer != null) {
                    outData= new byte[bufferInfo.size];
                    outputBuffer.get(outData);
                    //                            if(bufferInfo.size >=  outData.length){
                    //                                outputBuffer.get(outData, 0, outData.length);
                    //                            }else{
                    //                                outputBuffer.get(outData);
                    //                            }
                    
                                            }

设置的参数过多

    java.lang.IllegalStateException: link program:ERROR: 0:10: 'constructor' : too many arguments 

顶贴坐标shader多了输入参数
[SurfaceTexture-1-10520-0] bindTextureImage: clearing GL error: 0x500
