[maemo-developers] [maemo-developers] Ogg Vorbis and the N800 - Theora encoding

After failing to combine theora and tremor I played with the n800 web cam.
Theora encoding can be done by (as example)

gst-launch-0.10 v4l2src ! 
ffmpegcolorspace ! "video/x-raw-yuv",width=640,height=480,framerate=30/1 ! 
theoraenc bitrate=100 ! oggmux ! filesink location=target.ogg   

Well, playback is in fast forward mode then ;-) Do I need to add some kind of 
a 'timeoverlay' ?

Raw video encoding (I420) is done by

gst-launch-0.10 v4l2src ! 
ffmpegcolorspace ! "video/x-raw-yuv",width=352,height=288,framerate=30/1 ! 
avimux ! filesink location=target.avi

Cpu usage is below 45%.

Regards Krischan
