[MEncoder-users] "selected video_out device is incompatible with this codec"

[Tommy Butler]

Greetings fellow mplayer/mencoder users!

My company recently purchased some software that makes use of mplayer 
and mencoder.  Sadly, when the software runs it fails to produce the 
expected output.  It's purpose is to generate .flv format files, but it 
generates zero size files and fails with the error "The selected 
video_out device is incompatible with this codec"

I'm going to go ahead and paste in the full command and full error 
output.  Any insight would be so greatly appreciated.  Any thoughts 
anyone?  What can I do/read that will point me towards a solution?

REMEMBER: MEncoder's libavformat muxing is presently broken and can generate
INCORRECT files in the presence of B frames. Moreover, due to bugs MPlayer
will play these INCORRECT files as if nothing were wrong!

Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.
