【Android】【音视频开发】SurfaceView播放Rtsp媒体流

import android.content.Context;
import android.media.MediaCodec;
import android.media.MediaFormat;
import android.util.AttributeSet;
import android.view.SurfaceView;

import java.nio.ByteBuffer;

public class RtspPlayer extends SurfaceView {

    MediaCodec mediaCodec;

    public RtspPlayer(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(context, attrs);
    }

    private void init(Context context, AttributeSet attrs) {
    }

    public void configure(int width, int height) {
        try {
            mediaCodec = MediaCodec.createDecoderByType("video/avc");
            MediaFormat mediaFormat = MediaFormat.createVideoFormat("video/avc", width, height);
            mediaCodec.configure(mediaFormat, getHolder().getSurface(), null, 0);
            mediaCodec.start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public void onVideoFrame(byte[] frame) {
        ByteBuffer[] inputBuffers = mediaCodec.getInputBuffers();
        int inputBufferIndex = mediaCodec.dequeueInputBuffer(-1);
        if (inputBufferIndex < 0)
            return;

        ByteBuffer inputBuffer = inputBuffers[inputBufferIndex];
        inputBuffer.clear();
        inputBuffer.put(frame, 0, frame.length);
        mediaCodec.queueInputBuffer(inputBufferIndex, 0, frame.length, 0, 0);

        MediaCodec.BufferInfo bufferInfo = new MediaCodec.BufferInfo();
        int outputBufferIndex = mediaCodec.dequeueOutputBuffer(bufferInfo, 100);
        while (outputBufferIndex >= 0) {
            mediaCodec.releaseOutputBuffer(outputBufferIndex, true);
            outputBufferIndex = mediaCodec.dequeueOutputBuffer(bufferInfo, 0);
        }
    }
}

configure方法设置视频大小，将MediaCodec与SurfaceView绑定 onVideoFrame方法将rtsp的流数据，通过MediaCodec转码显示在SurfaceView上
