[MPlayer-users] impossible to encode TV signals with mencoder now; video buffer full droppinf frames

[Alain Barthélemy]

I was happy with a SuSE-8.2/AMD Athlon XP 2000+/512 Mb RAM/ATI Radeon
RV250/Pinnacle PCTV/Rave. MPlayer 1.0Pre7 worked perfectly on it for my
modest uses. TV signal encoding was all right with mencoder.

Now I have a AMD Athlon 64 3500+/1Gb RAM with same Video and TV card.

I thought that I would not have problems with MPlayer but...

Debian Sarge: impossible to install correctly MPlayer 1.0Pre8 (no image
when playing an avi file) with 1.0Pre8 sources.

Thus I installed SuSE-10.0. First, difficulties to install manually the
1.0Pre8 sources (no image again, no video vs x11 vesa drivers). Then the
installation crashed. Thus I installed the RPM file from Packman. I can
now read my avi files, DVD's, but, problem with encoding TV signals.

I read my TV signal without problem with following instruction line:

mplayer -tv driver=v4l2:width=720:height=576 tv://

Normally, there should be no problem with mencoder:

Here is my mencoder command line (it has worked for many months on my
previous PC):

/usr/bin/mencoder -tv driver=v4l:width=720:height=576:amode=1 -oac lavc -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=2200:vratetol=32000:mbd=2:psnr:aspect=4/3:acodec=mp3:abitrate=224 -vf crop=672:528:24:24,pp=lb,scale=576:432,hqdn3d=3:2:5 -sws 1 -noodml -ffourcc DIVX tv:// -o temp1.avi -endpos 1380

No encoding but  "video buffer full - dropping frame"

No problem to rip DVD's. Only to read TV signals. Long time ago, I had
dropping frames problems and I reduced the width to 720px and the height
to 576px. What should I modify to avoid these "video buffer full dropping frames". Normally I have a stronger CPU and more RAM now, video card is the same.
