Hi all,
With vlc 0.9, i used this command to record my tnt channel :

vlc /opt/TNT/TntNancy.conf --sout '#duplicate{dst=display,dst=std{access=file,dst=/home/tigermick/Bureau/EnregistrementTnt.avi}}'

but a little time ago, i have migrated my version of vlc to 1.0, and this command doesn't work again.... my file "enregistrementTnt.avi" don't have video content ...just audio data.

when i try to start my command in terminal, i have this message :

Same issue here, using mosaic to combine inputs the audio sporadically fails to add when using the mp4 container. Using ogg works, but then i can not encode the matrix with h264, which allows the use of multiple cores and thus allows the who thing to keep up with the streams and full size. I can use ogg but then i have to half the size of my canvas, and undesirable trade off.
