Hello,
A long standing question that I have is about capturing from the bktr device
using mencoder (from the mplayer package).
Until now I have tried several versions of mplayer without any luck. Even
using the patch from Steve O'Hara, which provides YUV colorspace conversion
for the bktr driver, didn't make any difference.
below I attach the result from running mplayer under Gnu/Linux and FreeBSD,
seems like a problem between mplayer and the bktr driver about which raw
video codec to use.
does anybody have a working mplayer/mencoder under FreeBSD 4.7???
thank you very much.
