Comment (by w3sip):

 Replying to [comment:8 heleppkes]:
 > I would strongly recommend to in fact not use the chunked decoding mode,
 and instead make use of the h264 parser to re-assemble the bitstream. The
 result should be the same, just using a more thoroughly tested code path.

 While I appreciate the recommendation, I'm not confident it applies in the
 cases where a 3rd party/non-FFMPEG network component is being utilized to
 receive H264 bitstream, and FFMPEG makes first appearance with the
 decoder.
 If I'm wrong, and there's a way to insert a codec parser between receiver
 and decoder using public FFMPEG API, I'd be thankful for any pointers on
 how to accomplish that.
