Hi I'm reverse engineering a DVR-Video-Format and was able to extract the h264-bytestream. The h264-bytestream does only contain IDR_SLICE, SEI and SLICE NAL-Units. So there are no SPS and PPS NAL-Units before each IDR_SLICE (which corresponds to AVCC scheme). I'm still searching for the SPS and PPS part in the DVR-Video-Format.
Feeding libav with this bytestream leads to the following error output: non-existing PPS 0 referenced decode_slice_header error non-existing PPS 0 referenced decode_slice_header error no frame! Which is logical, cause the decoder can't find any PPS NAL-Units in the bytestream. So how can I set PPS manually on the AVCodecContext, so the decoder is able to decode the bytestream? Best regards Michael
