My first post on this forum.
Recently bought RPI3b+ for use as net radio plugged to HiFi and a video player.
Soon I discovered some limitations: ALL usable OSes for RPI are 32 bit compiled for first RPI that uses ARMv6 (32 bit, no hardware accelerated video and software emulated floating point)
But RPI3b+ uses ARMv8, which includes four 64 bit cores with native floating point, hardware video accelerated GPU.
Then, another one: video accelerated hardware for 3b+ drivers at this time are compiled and working only for 32 bits (OpenMAX IL).
As a result of the above, the best possible result for hardware accelerated video is on Raspbian, ffmpeg & VLC recompiled manually.
Take a look here:

There are some mistakes in the above manual, but if you are know, how to compile, you can success.
I compiled ffmpeg-2.8.15 and vlc-2.2.8 - the latest possible and can confirm excellent video play (full HD h264 with no frame drops, CPU load less then 20%!)
