Now i write application to capture and encode video stream from V4L2
device to Theora/Ogg file (384x288 25fps). And i have low performance
problems on my athlon processor (2Ghz). Maybe i must change theora to
some faster codec (mpeg in ffmpeg?)

But maybe there is something which i can do to make better performance?
Example, i have code to convert RGB buffer to YUV buffer, but this is
can take lot CPU ticks.
(function ogg_encode_frame in
http://linpvr.googlecode.com/svn/trunk/src/ogg_enc.c )

Any suggestions ???

PS. Maybe someone know about applications like Analog VCR for v4l ?
