Hello again!
Well, the parser didn't work so far. But I still have a question:
When I deliver let's say four slices of a non-idr-frame to the
decoder: what about the startcodes?
- Prepending 0x000001 to the whole package?
-> (0x000001 + SSSS)
- Prepending 0x000001 to each Slice, but concantenate those four
slices and send them to decoder?
-> 0x000001 S + 0x000001 S +0x000001 S +0x000001 S
The FFmpeg h264 parser and h264 decoder expect to receive an input
bitstream in H.264 Annex B format. If you feed a different format in, it
is not going to work. Simply appending 00 00 00 01 to the front of a
bitstream is not likely to succeed, and this is not the proper way to
convert a random stream into Annex B format.
Annex B is defined in the ITU H.264 specification document. It will save
you much frustration if you google for this document, download it, and
read Annex B. Annex B is very short and not to difficult to understand.
It will answer these questions which you ask.
