hi,

i have been doing videostreaming now number of times and somehow i
always run into the same peculiar problem.

whenever there is more action on camera, especially zoomins and a lot
of audio (like bass and distorted vocals for example), the stream starts
to continously skip chunks of video stream of about 0.5-1 second,
every 0.5-1 second.

does anyone had a similar problem or knows what is the culprit? any
help greatly appreciated!!

i'm using

dvgrab --format dv1 - \
| ffmpeg2theora -f dv -x 393 -y 288 --no-skeleton -o /dev/stdout - \
| oggfwd skylined.org 8000 pass /mountpoint.ogv

i tried different cameras and ffmpeg2theora 0.24 and (now) 0.27
dvgrab 3.5
ffmpeg2theora 0.24 and 0.27
oggfwd 0.2
icecast 2.3.2

ubuntu 10.4 with 2.6.32 generic-pae kernel.
