Hey guys,here is one simple question: how do I obtain sps and pps from H264
stream(over RTP).I know through header & 0x1f==7 || header & 0x1f ==8 to
determine them,but what about their length?

Plus how to use them to "init" decoder?

I have been googled around,got a little confused,thanks for your help and
some code example would be appreciated!!


Best Regards
