[MPlayer-users] mencoder extremely slow creating mpegs

[Tony Smolar]

Greetings,

I have used mencoder for a long time to create DVD-compatible mpegs.   I 
had been using 1.0pre7try2 and was getting over 70-100fps while encoding.

Then I upgraded to a more recent Linux distribution, and 1.0pre7try2 no 
longer worked.   I built 1.0rc2 and the most recent version from svn (as 
of 2 days ago)

Now, I get a really slow 6 or 7fps while encoding with both of those 
versions, it takes forever to encode anything.

I'm not able to compile 1.0pre7try2,  but I was able to compile 
1.0pre8,   that version does encode fast again.  1.0rc1 seems to be the 
first version to have this problem for me.

I've tried searching the lists,  but I haven't been able to find anyone 
having the same problem.

The command line I'm using looks something like this: (the input is an 
mpg because it's from a Tivo, and I'm converting it to a dvd-friendly 
format)

/opt2/mplayer-1.0pre8/bin/mencoder somevid.mpg -of mpeg -oac lavc -ovc 
lavc -lavcopts 
acodec=ac3:vcodec=mpeg2video:vrc_buf_size=1835:vbitrate=2500:keyint=18:aspect=4/3:vpass=1:threads=2 
-mpegopts format=dvd -vf lavcdeint,scale=704:480,harddup -af volume=+5dB 
-mc 0 -srate 48000 -ofps 30000/1001 -o /dev/null

If anyone has any ideas or things for me to try to get more 
information,  let me know.   My processor is an AMD X2 3800+,  and I am 
running Fedora.

Thanks,
Tony Smolar
