I have tested ffmpeg build for win x64 (with decklink SDK modifications,
from latest source etc.) but it seems not all input options for decklink are
working:

Option >-bm_v210< is working but >-bm_channels< and >-bm_audiodepth< are
not.

For example:

 

ffmpeg -bm_v210 1 -f decklink -i "DeckLink 4K Extreme at 9" -acodec copy
-vcodec copy output.avi


 

works, but

 

ffmpeg -bm_audiodepth 32 -f decklink -i "DeckLink 4K Extreme at 9" -acodec copy
-vcodec copy output.avi


and

ffmpeg -bm_channels 8 -f decklink -i "DeckLink 4K Extreme at 9" -acodec copy
-vcodec copy output.avi


 

both give this type of error:

 

Unrecognized option 'bm_channels'.
Error splitting the argument list: Option not found

 

Can anybody check?
