[vlc-devel] [patch] H.264 packetizer causes loss of first frame

[Martin Kulas]

Hello!

During my VoD streaming experiments with the Big Buck Bunny movie
(720p, H.264 inside MOV container) I have noticed that
VLC (version 1.0.5) acting as a VoD server always drops the first
video picture.  In my packet capture file the RTP packets for the first 
I-frame are missing.  After patching the H.264 packetizer (see below)
the first frame is sent as RTP packets.

Is this patch OK?

Regards,
Martin
