Comment (by lizhong1008):
This clip is H264 6.0 level. However, The maximum level supported by MSDK
is 5.2.
There are some limitation on Intel HW platform (e.g: Skylake) to support
level 6.0+: Resolution larger than 4K is not supported, and there are some
other limitation such MV range(such is MB level limitation which is are
hard to check in MSDK and vaapi driver).
I wonder to know the possibility to exposing level 6.0+ in MSDK (at least
in API level, just like VAAPI is doing. Relative discussion:
https://github.com/intel/intel-vaapi-driver/issues/307). But anyway, I
believe this is not a ffmpeg issue and should be closed here.
