利用MediaCodec 获取视频的sps pps 和视频数据

 获取SPS、PPS

ByteBuffer spsb = videoEncodec.getOutputFormat().getByteBuffer("csd-0");
byte[] sps = new byte[spsb.remaining()];
spsb.get(sps, 0, sps.length);

ByteBuffer ppsb = videoEncodec.getOutputFormat().getByteBuffer("csd-1");
byte[] pps = new byte[ppsb.remaining()];
ppsb.get(pps, 0, pps.length);
