Hi,
b_ref_mode each option is not working by saying out:
`Each B frame as reference is not supported`
GPU is: GeForce GTX 1080 (Pascal based)
Can there be a link or explanation given for supported cards ?

Comment:
This ticket is missing a command line (Why don't you use 'ffmpeg -f lavfi
-i testsrc2' and drop any unneeded options?) but why do you think this can
be fixed in FFmpeg?
