Improper decoding of raw H264 video stream using android MediaCodec

I am building a screen sharing app and trying to receive raw H264 video stream from a socket and displaying it using surfaceview by decoding using MediaCodec class. However I am successfully able to receive data and display on surface. But the problem where I am stuck from two days is the video is very laggy,jittery and having green bands and patches. You can see the issue in the youtube video link. If I save this video to sdcard and play it using MxPlayer then it is playing fine.Also I tried with Gstreamer and everything is fine. This is my class calling from Activity when surfaceview is created.

//New Edited Code
public class Server {
static final int socketServerPORT = 53515;
MainActivity activity;
ServerSocket serverSocket;

public Server(MainActivity activity, Surface surface) {
    Log.e("constructor()", "called");
    this.activity = activity;
    Thread socketServerThread = new Thread(new SocketServerThread(surface));
    socketServerThread.start();
}

private static MediaCodecInfo selectCodec(String mimeType) {
    int numCodecs = MediaCodecList.getCodecCount();
    for (int i = 0; i < numCodecs; i++) {
        MediaCodecInfo codecInfo = MediaCodecList.getCodecInfoAt(i);

        if (codecInfo.isEncoder()) {
            continue;
        }

        String[] types = codecInfo.getSupportedTypes();
        for (int j = 0; j < types.length; j++) {
            if (types[j].equalsIgnoreCase(mimeType)) {
                Log.e("codecinfo", codecInfo.getName());
                return codecInfo;
            }
        }
    }
    return null;
}

private class SocketServerThread extends Thread {
    InputStream is;
    Socket socket;
    private MediaCodec codec;
    private Surface surface;

    public SocketServerThread(Surface surface) {
        this.surface = surface;
    }

    @Override
    public void run() {
        Log.e("socketthread", "called");
        try {
            selectCodec("video/avc");
            codec = MediaCodec.createByCodecName(selectCodec("video/avc").getName());

            MediaFormat format = MediaFormat.createVideoFormat("video/avc", 800, 480);
            //  format.setInteger(MediaFormat.KEY_COLOR_FORMAT, MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface);
            format.setInteger(MediaFormat.KEY_BIT_RATE, 1024000);
            format.setInteger(MediaFormat.KEY_FRAME_RATE, 25);
            codec.configure(format, surface, null, 0);
            codec.start();
            serverSocket = new ServerSocket(socketServerPORT);
            while (true) {
                socket = serverSocket.accept();
                Log.e("connection", "accepted");
                is = socket.getInputStream();
                if (is != null) {
                    //          File file = new File(Environment.getExternalStorageDirectory() + "/stream.mp4");
                    //              OutputStream output = new FileOutputStream(file);
                    byte[] buff = new byte[4 * 1024]; // or other buffer size
                    int read;
                    while ((read = is.read(buff)) != -1) {
                        //              output.write(buff, 0, read);
                        if (buff.length == 1)
                            continue;

                        int inIndex = codec.dequeueInputBuffer(10000);
                        if (inIndex >= 0) {
                            ByteBuffer inputBuffer = codec.getInputBuffer(inIndex);
                            inputBuffer.clear();
                            inputBuffer.put(buff);

                            codec.queueInputBuffer(inIndex, 0, buff.length, 16, 0);
                        }

                        MediaCodec.BufferInfo buffInfo = new MediaCodec.BufferInfo();
                        int outIndex = codec.dequeueOutputBuffer(buffInfo, 10000);

                        switch (outIndex) {
                            case MediaCodec.INFO_OUTPUT_FORMAT_CHANGED:
                                break;
                            case MediaCodec.INFO_TRY_AGAIN_LATER:
                                break;
                            case -3:
                                break;
                            default:
                                codec.releaseOutputBuffer(outIndex, true);
                        }
                    }
                }
            }

        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (codec != null) {
                codec.release();
            }
            if (socket != null) {
                try {
                    socket.close();
                    is.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
  }
}

I tried the way you mentioned to create MediaCodec as

MediaCodec.createByCodecName(selectCodec("video/avc").getName());

   private static MediaCodecInfo selectCodec(String mimeType) {
    int numCodecs = MediaCodecList.getCodecCount();
    for (int i = 0; i < numCodecs; i++) {
        MediaCodecInfo codecInfo = MediaCodecList.getCodecInfoAt(i);

        if (!codecInfo.isEncoder()) {
            continue;
        }

        String[] types = codecInfo.getSupportedTypes();
        for (int j = 0; j < types.length; j++) {
            if (types[j].equalsIgnoreCase(mimeType)) {
                Log.e("codecinfo",codecInfo.getName());
                return codecInfo;
            }
        }
    }
    return null;
}

but it gives me error

I/OMXClient: MuxOMX ctor

Also I tried to create Mediacodec earlier by this method

codec =  MediaCodec.createDecoderByType("video/avc");

but the video quality remains same as in the video shared on youtube.
