[aac @ 0x7f610c01c480] Unsupported channel layout "1 channels" #226

Closed alatteri closed 2 years ago

alatteri commented 2 years ago

I just updated to latest UG, and I am getting this when I try to capture Decklink audio. uv -m 1316 -t decklink:codec=R10k -c libavcodec:encoder=libx264::bitrate=35M -s embedded --audio-capture-format channels=8 --audio-codec=AAC:bitrate=192K -P 5004

Video only works fine.

So this is broken some time after 4cb847908a8d7f3c50938a04b07fb216c2940ce2 I would assume it is b4eff8ed39ecf01cd45cb42ba0f10190a4710a79

Thanks for reporting. You are right, it got introduced in https://github.com/CESNET/UltraGrid/commit/b4eff8ed39ecf01cd45cb42ba0f10190a4710a79. It seems like the aac encoder doesn't like unspecified channel order. Should be fixed in https://github.com/CESNET/UltraGrid/commit/053640ce696624b1f443f4b7dc87c6782cb5ffa8. Please reopen if the problem persists.
