[Live-devel] x264 nal unist and H264VideoStreamDiscreteFramer

[Ross Finlayson]

> Warning: Invalid 'nal_unit_type': 0.  Does the NAL unit begin with a MPEG 'start code' by mistake?

This message means exactly what it says (and you can very easily see - in the "H264VideoStreamDiscreteFramer" source code - where/why it's displayed).  Remember, You Have Complete Source Code.

Most likely, the H.264 NAL units that you are (trying to) feed into the "H264VideoStreamDiscreteFramer" begin with a MPEG 'start code' (0x00000001 or 0x000001).  You must not do this.  Instead, you need to skip over these 'start code' bytes before feeding the NAL unit data into the "H264VideoStreamDiscreteFramer".  (Remember also to reduce "fFrameSize" accordingly.)
