Decoding x-rtvc1 RTP Streams ?
on Dec 17, 2011 at 12:04:49 am

Hello,

Does anyone know how to decode the Video Streams from e.g. MSN Messenger 2011 ?

The new Windows Live Messenger uses rtvc1 as Video Stream. The earlier versions used ml20 as stream.

I managed to decode all I-Frames of such stream, but i cannot decode the B and P Frames.
rtvc1 is a VC-1 based Codec, but it has some modifications for the RTP transmission.

If i decode the I Frames, the Video runs too fast, because there are the B,P frames missing. The B,P frames are in my stream File, but the Decoder of ffmpeg only accepts the I Frames and skippes the B,P frames.

I hope someone here is interested in decoding this streams, on roundup i´ll got responses from some users, but after a while they dropped the idea of decoding rtvc1 :(

Sorry for my bad english

Greetz Chris

when i try to play msn wireshark capture rtvc.vc1 file by removing all cc000000 and dc000000 then using ffmpeg it playing but we getting some error
1>Luma scaling is not supported, expect wrong picture.
2>Chroma scaling is not supported, expect wrong picture.
and video playing so fast.
so there is some specific decoder or player to play that file.
note:={i think there is some mac player can able to play but i m not sure..}
