[MPlayer-users] FreeBSD tv card -> divx capture

[Anish Mistry]

I have been using an old version of mencoder with the bsdbt848 tv capture 
since febuary.  This old version works fine no A/V sync issues on my 650Mhz 
Duron.  I've been trying to get a newer version of mplayer to work correctly, 
but I keep running into a strange problem with the newer versions.  The cpu 
usage for mencoder slowly continues to drop over to period  that I am 
recording until it is around 5%-10% cpu usage.  Nothing else is running and 
during this time the recorded video starts skipping.  I can seem to work 
around this problem, by specifying the -fps flag to mencoder:
./mencoder -tv 
on:driver=bsdbt848:norm=ntsc:width=320:height=240:input=1:chanlist=us-bcast:channel=13 
-lameopt br=64:cbr -divx4opts q=1 -fps 30
But this causes A/V sync issues a few minutes into the recording, but the cpu 
utilization hovers around 80% so it doesn't seem that my cpu can't keep up.  
Like I said before it worked fine with the 6 month old verison of mencoder.  
I have tried various different CVS snapshots and pre-releases all with 
different compile options etc and still have this problem with the newer 
versions since Febuary.
Any suggestions?
