[Libav-user] avcodec_decode_video2 with h264

[Joshua Kordani]

Greetings all.

I have a bitstream consisting of just idr and p frames, (nals type 5 and 1).

How do I present them in the AVPacket being fed to the decode call?

[7 8 5] [7 8 5 1] [7 8 5 1 1]...
or
[7 8 5] [1] [1] [1] [1]

Do I prepend startcodes to the [1] buffer?

If I see a new idr frame, do I need to present [7 8 5] again? or just [5]?

Any documentation I can read that describes how this should be done in 
general, at least with h264?

Thanks all
