Comment (by Balling):

 I actually found the only place where it makes a difference: apparently
 this file md5 of both [NV12] output of -hwaccel nvdec and -c:v h264_cuvid
 are bitperfect and both do not care about the patch above increasing stuff
 to 256. While both -hwaccel d3d11va and -hwaccel dxva2 care about this,
 they need 64 MAX_SLICES to be bitperfect NV12 with nvdec and cuvid. That
 can be checked on this file and this: https://github.com/wang-
 bin/QtAV/issues/923

 Very cool. But I doubt that this is somehow issue in h264, I think this is
 just dxva bug.
