核心是，用博主的方法录制视频后许多人发现无法播放，主要问题是 DataInputStream的readInt()方法读取的值太大（之后会提到)，readInt()是用来读取四个字节并以十进制表示这四个字节代表的数值
我们先来看看MediaRecorder使用H264编码的具体情况，问题就处在这里
PS: CSDN 的代码排版真是越来越坑爹了
//获取SPS和PPSpublic class GetSPSAndPPS {private byte[] SPS;private byte[] PPS;private final int PARA_SPS = 0;private final int PARA_PPS = 1;public GetSPSAndPPS(byte[] in){int dataLength = in.length;// ‘a’=0x61, ‘v’=0x76, ‘c’=0x63, ‘C’=0x43byte[] avcC = new byte[] { 0x61, 0x76, 0x63, 0x43 };// avcC的起始位置int avcRecord = 0;for (int ix = 0; ix < dataLength; ++ix) {if (in[ix] == avcC[0] && in[ix + 1] == avcC[1]&& in[ix + 2] == avcC[2]&& in[ix + 3] == avcC[3]) {// 找到avcC，则记录avcRecord起始位置，然后退出循环。avcRecord = ix + 4;break;}}if (0 == avcRecord) {handleMainThread("Cannot find avvC");return;}int spsStartPos = avcRecord + 6;byte[] spsbt = new byte[] { in[spsStartPos],in[spsStartPos + 1] };int spsLength = bytes2Int(spsbt);SPS = new byte[spsLength];spsStartPos += 2;System.arraycopy(in, spsStartPos, SPS, 0, spsLength);int ppsStartPos = spsStartPos + spsLength + 1;byte[] ppsbt = new byte[] { in[ppsStartPos],in[ppsStartPos + 1] };int ppsLength = bytes2Int(ppsbt);PPS = new byte[ppsLength];ppsStartPos += 2;System.arraycopy(in, ppsStartPos, PPS, 0, ppsLength);handleMainThread("Find SPS and PPS!");}private int bytes2Int(byte[] bt) {int ret = bt[0];ret <<= 8;ret |= bt[1];return ret;}public byte[] getParameter(int type) {switch(type){case PARA_SPS:return SPS;case PARA_PPS:return PPS;default:return null;}}private void handleMainThread(String s) {Message msg = new Message();Bundle b = new Bundle();b.putString("String", String.valueOf(s));msg.setData(b);try {RAS_MAIN.myhandle.sendMessage(msg);} catch (Exception e) {System.out.print(e.getMessage());}}}
，一个人去旅行，而且是去故乡的山水间徜徉。
