Dears, I am thinking of setting up a multichannel live streaming solution using gstreamer. Up to now my biggest unknown is the possibility to adjust gstreamer plugin parameters on-the-fly, and especially one to control the pitch of an audio resampler. I would need to change it either manually (myself during the encoding) or via smart algorythm. Does anyone woule have already done something like that ? To understand the background: I want to synchronise the audio from a multichannel audio card to the one of a video capture card to eventually get the equivalent of a very expensive video+multichannel audio card. The idea would be to compare a reference audio channel on both card and based on the result to speed up (a little bit !!) or slow down the channels from the audio only card. Many thanks, Timothe
