[MPlayer-users] Question on ERROR: SCR:

[Philip Walden]

I typically create movies with sound from many webcam jpegs.

mencoder -audiofile RebelBlockadeRunner.mp3 -vf harddup -ofps 24000/1001 
-of mpeg -mpegopts format=mpeg1 -ovc lavc -oac lavc -lavcopts 
acodec=mp2:vcodec=mpeg1video:keyint=25 -o test.mpg mf://*.jpg -mf 
type=jpeg:fps=24

Sometimes it works completely fine, but most times I get several errors, 
for example.

What are these? I notice when I play these movies in quicktime player, 
the sound sounds fien, but the movies skips frames. If I single step the 
player, the skipped frame appear to be there.
