[MEncoder-users] FLV Conversion Problems

I limited the framerates to 25000/1001 via the -ofps command as
suggested on here and it has really helped my WMV playback a lot.
However, the WMV videos still play a little choppy and MOV videos are
now converting very poorly. I am currently resizing videos to 1280x720
with a vbitrate of 3,168

Is it possible that the vbitrate I am converting too is causing the
problems? Also it seems that it is mostly h.264 videos that are having
this playback issue in both formats.


The commands:
if($config[vresize] == 1) {$encodecommand="$config[mencoder]
$config[vdodir]/$vdoname -o $config[flvdodir]/".$vid."x.flv -of lavf
-oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts
vcodec=flv:vbitrate=$config[vbitrate]:mbd=2:mv0:trell:v4mv:keyint=10:cbp:last_pred=3
-lavfopts i_certify_that_my_video_stream_does_not_use_b_frames -ofps
25000/1001 -vop scale=$config[vresize_x]:$config[vresize_y] -srate 22050
$config[sbitrate]";}

else {$encodecommand="$config[mencoder] $config[vdodir]/$vdoname -o
$config[flvdodir]/".$vid."x.flv -of lavf -oac mp3lame -lameopts
abr:br=56 -ovc lavc -lavcopts
vcodec=flv:vbitrate=$config[vbitrate]:mbd=2:mv0:trell:v4mv:keyint=10:cbp:last_pred=3
-lavfopts i_certify_that_my_video_stream_does_not_use_b_frames -ofps
25000/1001 -srate 22050 $config[sbitrate]";}
