mplayerhq (it is a pitty, but I was not able to compile the svn
source):
mencoder -endpos 60 -o zzz.avi tv://\
-tv driver=v4l2:normid=0:input=1:width=720:height=576:\
alsa:adevice=hw.1:amode=1:immediatemode=0\
-ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1200:autoaspect\
-oac lavc -lavcopts acodec=ac3:abitrate=96:threads=2 -af volnorm\
-vf crop=688:560:16:8,pp=lb -ffourcc XVID
The problem is that when trying to skip frames (pressing right/up arrow)
during playing the obtained zzz.avi, the sound playback starts over.
Furthermore, there is some A/V syncing problem (the sound is in late
relative to the video) even without skipping.
I have attached the output... no idea what the problem is. Previously I
used the syntax above with 1.0pre7try2 on another machine without any such
problem.
TIA,
Zsolt
