 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

 This is not absoulutely true because ret of nvenc_check_cap() we do not
 check (ret != 1 || ret != 3)
