This problem has already been submitted mny times by the past and has never encountered an answer.
That is:
when using VLC in VLM configuration and asking it to vod a flow coming from a grabber, VLC/VLM claims that it doesn't know the RV24 codec
whereas asking VLC to record the same flow (so the same codec) there is no problem at all!
So, where is the labyrinth's exit asked Alice?
