h264解码的有关问题

h264解码的问题

现在用的是TI的Codec,但只能正确解出其中的关键帧，也就是第1、第16、第31帧...可以正确解出，其它的Codec会报错。哪位高手能帮分析一下原因呀？


------解决方案--------------------
建议看看MPEG4-10部分的文档。。

------解决方案--------------------
不用客气，h264的常用解码器因为都需要一帧一帧的传，否则解码失败，当然你自己也可以写h264解码器支持查找解码，elecard的h264解码器好像就可以。mpeg2,ac3等常用解码器都支持这种任意分割解码，所以可以不用查找，起码微软的mpeg2 demuxer是这个做的。
你先看看payload_unit_start_indicator=1TS包的数据段开始是不是PES的00 00 01 e0 (也可能是e1~ef)开头的，然后看一下PES后面的ES（H264流）数据段开始是不是H264的NAL头 00 00 00 01 xx开始。如果是的话，证明每个PES包包含完整的N帧，查找就简单一点，时间戳比较好打，自需要在这个PES中分离帧就行了。如果不是就比较麻烦了，要将相邻的PES里面的ES数据连接起来查找，不知道帧的开头和结尾，查找麻烦点，时间戳也麻烦。
H264的N帧纯数据的分离帧代码参如下：

C/C++ code

//分解： BYTE *pData, int nLen;

int nPrevCode = 0;
int nFrames = 0;

BYTE *pFrameData = pData;
int nFrameLen = nLen;

BYTE *pH264Data = pData;
int nH264Len = nLen;
while(nH264Len >= 4)
{
    if(pH264Data[0] == 0x00 && pH264Data[1] == 0x00 && pH264Data[2] == 0x01)
    {
        int code = pH264Data[3] & 0x1f;
        if(code == 0x01 || (code >= 0x05 && code <= 0x09))
        {
            if(nPrevCode == 0x01 || nPrevCode == 0x05)
            {
                if(nFrames > 0)
                {
                    if(pH264Data[-1] == 0x00) pH264Data--;
                    nFrameLen = pH264Data - pFrameData;
                    // push_frame(pFrameData, nFrameLen)
                    pFrameData = pH264Data;
                }
            }

            nPrevCode = code;
        }
        if(code == 0x01 || code == 0x05)
        {
            nFrames++;
        }

        pH264Data += 4;
        nH264Len -= 4;
    }
    else
    {
        pH264Data++;
        nH264Len--;
    }
}

nFrameLen = nLen - (pFrameData - pData);
// push_frame(pFrameData, nFrameLen)
