Comment:
Replying to [comment:4 smallishzulu]:
> As indicated, this mode is not supported at all, so the current
behaviour is correct. When this mode becomes available in the future, the
value returned on calling NvEncGetEncodeCaps() with the
NV_ENC_CAPS_SUPPORT_BFRAME_REF_MODE capability will include
NV_ENC_BFRAME_REF_MODE_EACH.
This is not absoulutely true because ret of nvenc_check_cap() we do not
check (ret != 1 || ret != 3)
