After switching from Ubuntu 9.04 to 10.04, screencasts I create with gtk-recordmydesktop are no longer working when I upload them to youtube.
The best I can figure out is that Ubuntu is using a new version of the theora encoder that apparently is not backward compatible. Perhaps Youtube is still using an older version that can't handle it, as someone suggested in this thread:
Here are some related threads and bug reports:
Here are some sample youtube videos demonstrating the problem:
My question is - is there any way to down-convert my ogv video screencasts to an older, compatible version of theora or whatever. Can I convert it to something compatible with ffmpeg or mencoder or mkvmerge or whatever. Just converting to mkv or avi first and then uploading to youtube does not work (so it may be still an ubuntu issue, too).
I'd rather not have to completely re-install ubuntu 9.04 just for this one issue.
