[vlc-devel] FFmpeg video scaling problem

[Brian C. Wiles]

It doesn't look like there's any difference.  As an experiment, I tried 
changing it to always set the level to 4, but that still didn't work.  
Apparently, the problem lies somewhere else or I missed something.

I should also note that this is the line I'm using to transcode a video:

#transcode{vcodec=mp2v,vb=8192,width=1920,height=1080,canvas-width=1920,canvas-height=1080,canvas-aspect=16:9}:gather:standard{mux=ts,access=udp,dst=239.255.1.1}

This doesn't work under the Qt4 interface either.  For some reason, it 
says it's streaming, but it doesn't.
