[MPlayer-users] trouble with MPEG-PS video

[Dave Wayne]

I've been trying to encode a video in MPEG-PS format but I either get green
lines all across the screen or an unplayable video and could use any advice.

Here is the latest attempt (which results in an unplayable video)

/usr/local/bin/mencoder original-video -ovc lavc -oac copy -o new_video.avi
-v  -lavcopts vcodec=mpeg4

The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.
