I've been quite happy with this build except for the shifting subtitles but that's fixed, right? I do have a few VC-1 files and they don't play well. Lots of stuttering, just..not good.
This is being looked at by people much smarter than me working on AML HW decoding in Kodi.
I guess I'll have to get used to that because only 60,50,and 25 are supported not 59.97, 29.675 and 23.95 (or something close to those 3) unlike the RPi who supports them all. I miss that but it's still a great build.
Fractional frame rates are supported in kernel but you won't see them in GUI - these are handled automatically by kernel when you play a video with fractional frame rate.
