[MPlayer-users] please help with video capture

[Jack]

Sometimes, when just copying the stream from a capture card, the hard 
drive can't write fast enough to keep up with it.  If you encounter this 
problem, you'll have to switch your capture card to mjpeg output 
(assuming it supports it) by adding "mjpeg" and "decimation=<1,2, 4>" to 
your -tv options. decimation=2 will give you 352x240.

Or, if you have enough processor, you could simply encode to a lossless 
codec (such as huffyuv) on the fly. (-ovc lavc -lavcopts 
vcodec=huffyuv:vstrict=-1)
