> `-global_quality:v`
Hi,
I writed it in my report: `-global_quality:v` not uses the common range
1-31.
And for this reason h264_vaapi and others have `-qp`. Futhermore, the
GENERIC implementation of the VAAPI encoder has the `explicit_qp`
variable. And all vaapi encoders, EXCEPT the mpeg2 uses it. The request
it's to copy&paste the four lines of code from `vaapi_encode_h264.c` to
`vaapi_encode_mpeg2.c`
So I reopen the ticket as it's valid.
Regards.
