[Live-devel] Questions about project to dump Images frames from H264 stream using live555 and ffmpeg

Whoa!  Hold on - this line tells me that your input stream is *not* a H.264 RTP stream.  Instead, it's a MPEG Transport Stream (that may, or may not, contain H.264, or MPEG-4, or MPEG-2, or a number of other things).

This is your problem: You're treating your input stream as if it were a H.264 stream - but it's not.  Because your data is MPEG Transport stream, the way in which you decode it is completely different.  (You don't deal with NAL units, or anything like that, because that's all hidden within the Transport Stream.)
