avprocessor: can add dummy video

Clement Champetier · Clement Champetier · commit a956861cc457 · 2014-08-04T16:58:27.000+02:00
* If dummy video, need a VideoDesc.
* Warning: can't add a dummy audio, because we need an AudioDesc... Need
to add this information in the confi file. Maybe it will be easier in
python!
