android播放vp8透明,surfaceview - Android MediaCodec encode and decode using vp8 format - Stack Overflow...

I want to develop an app, which will have 2 buttons and SurfaceView(Actually a class extends SurfaceView implements SurfaceHolder.Callback).

When user click on button1 - with ScreenCapture, I will get an image and using mediacodec, I will do vp8 encoding and the output saving in bytebuffer.(I am not saving in a file location)

When user click on button2 - I need to show it on SurfaceView with that output of bytebuffer which is captured.

i have tried as

MediaCodec decoder = MediaCodec.createDecoderByType("video/x-vnd.on2.vp8");

decoder.dequeueOutputBuffer(mBufferInfo, DEFAULT_TIMEOUT_US);

.....

but not able to update the surfaceview.

How can i update the surfaceview using bytebuffer data?
