the aspect ratio on mencoder streaming most time dont match. I need manually set VLC to use aspect ratio = 16:9.
On streaming with ogg it works.

In the log you should find the actual mencoder call used by externremux.sh. Which options are used?

In your first example, scale=520:-3 should scale the video to a width of 520px. According to the mencoder documentation -3 means "Calculate w/h using the other dimension and the original aspect ratio". In your second example there's no scaling option at all. So I don't see a problem caused by streamdev here. Maybe there's something wrong with your client or with mencoder (I'm no mencoder expert - perhaps an option is missing?).
What happens if you take a VDR recording and run it through mencoder, using the same parameters?
