Sorry I can't make much comment about the other ffmpeg issues you raise at moment, I might get back to you on some of the issues when I get back from holiday leave next week or Piers may have something to say.<br>
<br>
The VDPAU support which uses an Nvidia GPU to do the H.264 decoding looks interesting as does the new ffmpeg-mt branch:<br>

On the topic of ffmpeg, does anyone have experience with getting any debug info out of it? I'm trying avcodec_thread_init to initialize multithreading (both encoding and decoding), but it always seems to fail, returning -1. This is after I have it loaded with mpeg4 as the codec, plus I made sure ffmpeg was configured with --enable-pthreads. I have seen significant performance improvements when using multithreading while encoding mpeg4 with ffmpeg (as in the command-line encoder), so it seems like it should be possible when doing it within vic. Anyone have any ideas? Leon? :) If I can't work my way around this I might check out the mt branch to see how nicely it plays with vic.<br>
<br>Also - while testing the SVN vic, it looks like multicast doesn't work. I can receive unicast streams, and see loopback of local video, but when trying to connect to a multicast address, it seems like it's not even joining the group, since the machine isn't receiving any data. I know multicast works in general on the machine since older vics work fine, including a couple month-old SVN version. Has anyone seen this happen?<br>
