I see the problem, but if I use mplayer -fs -zoom -quiet -vo ivtv %s
then the video plays perfectly smoothly, it's just about 1 and a half
times the size that it should be, so much of it is missing from the
screen.
also quoting from Jarod's guide:
'with the ivtvdev X driver, the measly 1GHz Via C3 in my EPIA (runs
like a PIII-600) can decode and play back high-resolution xvid and
ffmpeg4 encoded DVD rips without a problem'
Which implies that there should be a solution out there somewhere.
Has anyone using a PVR 350 had decent results using the TV out to play
high resolution XVids and if so what command do you use to start
mplayer?
Currently I can use:
ivtvfbctl -alpha 0; mplayer -fs -zoom -quiet -vo ivtv %s; ivtvfbctl -alpha 255
which gives me the wrong size video
or
mplayer -fs -zoom -quiet -vo ivtvosd %s
which shows no video and spits out a load of errors along the line of:
Error with sending DMA to ivtv FB! Invalid argument
