[MEncoder-users] ERROR: SCR: warning; what does that mean?

[Brian Keener]

I'm re-encoding a huffyuv-encoded file to mpeg2, dvd-compatible video 
stream.

My command line is:

mencoder tv.avi -of mpeg -oac lavc -ovc lavc -lavcopts 
vcodec=mpeg2video:vbitrate=8000:keyint=25 -vf 
hqdn3d,pullup,pp=md,scale=720:480 -noskip -o tvout.mpg

I'm pretty happy with the quality, but I'm still getting lots of errors like

ERROR: SCR: 874360377, APTS: 844830475, DELTA=-0.320 secs

ERROR: SCR: 874469454, APTS: 849649125, DELTA=-0.269 secs

ERROR: SCR: 874578531, APTS: 856877100, DELTA=-0.192 secs

ERROR: SCR: 874796685, APTS: 871333050, DELTA=-0.038 secs

Also, mencoder seems to try to maintain re-encoding performance of 
~30fps, when I'd expect the re-encoding to run substantially slower, 
especially with the scaling/noise reduction/etc.  I'm not talking about 
the fps of the outputted file, I'm talking about the number of frames 
processed by mencoder per second.

Any information?
