[FFmpeg-user] Packets are not in the proper order with respect to DTS

Hi

I'm trying to stream video from a camera to a twitch stream (ghoto2 ->
ffmpeg -> twitch) .
It works good without audio, but twitch doesn't like the stream. Therefore
I want to add a silent audio track.
This I'm doing with the aevalsrc filter, but this gives me an DTS error for
the flv output (it runs for a second and then crashes)?
How do I make sure the streams are synchronised?

command and output can be found below.

Cheers

Pål
