Thank you for your quick replay and sorry for the delay.

Same problem with an input file.

With Ubuntu 10.4 both, the native package and ffmpeg-0.8.2.tar.gz work.

"ffmpeg -r 18 -i t.avi http://localhost:8090/feed1.ffm" converts 300 fps and 
uses 100% cpu. Is ffmpeg supposed to convert at maximum speed?
ffserver uses less then 1% cpu.

With Ubuntu 11.4 same problem with package and the jar.
ffmpeg uses 50% cpu (only user), ffserver uses 50% cpu (1/4 user 3/4 sys). 

By the way - there seems to be a new glitch in the git head snapshot.
"ffmpeg -r 18 -i t.avi http://localhost:8090/feed1.ffm" says:
Output #0, ffm, to 'http://localhost:8090/feed1.ffm':
    Stream #0.0: Invalid Codec type -1

Best regards, Edwin
