H.261 codec improvements: msg#00301

Subject: H.261 codec improvements

Hello

The current h.261 codec used in openh323/OPAL (vic) is from the early-90's and has some problems dealing with advanced h.261 streams (often coming from MCU's). This is probably due to the fact that the vic-codec has problems with frames containing non-I-macroblocks (Poor quality when there is much movement in the frame)

I recently visited the ffmpeg project page and noticed that the have added some h.261 support (dec 10, 2004)
Since the openh323 libraries already utilise libavcodec.so to make use of H.263, I just wonder whether using the ffmpeg h.261 codec would be an improvement. Does anybody know more about that?
