Replying to [comment:13 atorp]:
>However, to disable QVBR I need to disable CO3 too... or the code doesn't
compile. I'm sure CO3 isn't related to this bug.
Why it can't compile? I applied such a patch on my side (without any other
changes such as disable CO3):

Compile passed on my side （still on Linux）.
> Here it is: Initialize MFX session: API version is 1.27, implementation

Your MSDK API version is 1.27 but MSDK library version is 1.11 which is
quite old.

it.
Tried it on one Windows platform, it works but provided a warning:

You can see the Waring (at your side it is an error): Warning in encoder
initialization: incompatible video parameters (5)
I guess it is due to AVBR mode is not support for mpeg2, so I changed the
command line to be

Now it is using VBR mode and no warning now.
Could you please check this warning (Warning in encoder initialization:
incompatible video parameters) existed or now with
https://ffmpeg.zeranoe.com/builds/win64/static/ffmpeg-20190124-3224d66-win64-static.zip?
If existed, I believe windows version MSDK can't support AVBR mode for
mpeg2.
