Hi,
Still having trouble to mixdown these 4 channels inside a stream:
audio_pipeline=
"audio/x-raw, channels=4 ! audioconvert ! audio/x-raw,
channels=2 ! voaacenc bitrate=96000 ! queue ! mux.",
it gives me this warning and no output on the stream:
audioconvert2: Upstream caps contain no channel mask
Unsure of how to procede. Do I have to put a channel/mask? For bitmask,
could not find any appropriate values.
Can somebody please give me a hand to get this thing going?
Cheers, Jeroen
