I created a version of swfdec 0.6.6 using mad and ffmpeg instead of gstreamer, because with gstreamer it failed to play multiple videos on youtube.com.
The release is available in my PPA at:
deb http://ppa.launchpad.net/juliank/ubuntu hardy main deb-src http://ppa.launchpad.net/juliank/ubuntu hardy main
I will also provide some builds of the development branch (0.7.1) soon.
Update:Maybe it was not clear, but the videos crashed the browser. It also didn’t really work in totem and I’m still looking for the source of the problem. I have every available gstreamer plugin package installed. Try it yourself, http://de.youtube.com/watch?v=CSp7jsV7oG0. It works with gnash, but gnash does not work with wordpress stats page.
Update 2: I now found the real problem: I had an binary version of fluendo’s mp3 plugin installed (from fluendo.com), which caused the crash. After removing the file, everything works. (using fluendo-mp3 shipped with Ubuntu).
Update 3: I removed the ffmpeg version from my PPA, as it is not needed.
