Comment (by staircase27):

 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.

 Hi,

 I'm not entirely sure how I would go about making use of the h264 parser
 to re-assemble the bitstream?

 Currently I am reading NAL unit packets using av_read_frame and then
 passing these packets to avcodec_send_packet and pulling the decoded
 frames out using avcodec_receive_frame. Is this re-assembing done by
 adding another call to ffmpeg to request it re-assemble the nal-unit
 packets back into larger nal-unit packets before passing to
 avcodec_send_packet or an option we pass in when creating the
 codec_context to request that ffmpeg does it internally?

 If you need any more details please can we discuss directly over emails?
 My email address is "staircase AT sector DASH alpha NOT net".

 Thanks,
 Simon
