Nice, IRQ kernel oops if you add alsa:// to the front it might work Yep, that works Besides the whole tuning thing, it works almost alright And the only reason it happened to be tuned to channel 3 was because that's what the Windows software tuned it to. After a power cycle, it's on some other channel now. Anyway, thanks for the help when talking an mcu vs sfu unit, an mcu receives multiple streams, decodes them and reencode them into 1 single stream does it mean that if he receives 320x240 stream1 and 320z240 stream2, he generates a 640x480 final stream and send that to each and every client?
