definately on vaapi, playback data confirmed (something i always use to confirm config) - i did discover that iso install of F29 didn't include the vaapi drivers, so had to install the libva-intel-drivers (and libva-utils). after this vaapi in f29 just worked.
that other thread you found of mine is a bit confusing based on this thread. First weekend rebuild was on on centos7 but had some excessive boot time details. I did have to install the libva stuff as well on centos7 to get mythtv to vaapi decode. f29 was a test to see what happens with the boot delays immediately after grub. halved it infact so i'm currently running f29. Also ships with kernel 4.x which is needed for bluetooth&logitech harmony pairing so seems easier to get running off the ground.
i'm not familiar with dri, so I've not knowingly done anything there.
just to highlight, the rebuild was done as i experienced issues on my existing centos7 & myth29 FE. Full OS update (with elrepo-kernel providing kernel-lt) & myth30 upgrade made the playback issue occur.
