Hi all, I'm trying to encode Decklink SDI input and stream it to NDI and keep the audio layout as is.
The SDI signal has 8 audio channels with the following layout: 1,2 Stereo 3,4 Stereo 5,6 Dolby 7,8 Stereo What I need to do is to passthrough all audio channels and to keep the layout as is. Tried "-ac 8 -acodec copy" but it doesn't seem to be working. Maybe I need to use something like "-map_channel" and then to define the audio output layout BUT to do so I need to know "stream_specifier.channel_id" and when I ffprobe the SDI input I get "channel_layout=unknown" which I think is a known issue with Decklink cards according to BM support forums > There is no format detection options for audio capture to determine the > number of audio channels provided by the video source. Can anyone help with the correct command to passthrough the audio channels? your inputs are highly appreciated.!
