Hello,

I'm trying to decode some mkv/H.264 video file, but I encounter a simple problem. All packets returned by av_read_frame() are marked as key_frame.

I tried to track down the issue, and it look like it come from the fact than the mkv demuxer require a parser for H.264, but the parser does not returns any information about the frame, and so, av_read_frame() thinks all readed packets are I-frame and tag them as key frame.


Is it a known issue ? and is there a way to workaround it ?

Thanks
