That likely 10bit H264 combo (aka 10bit Anime) is NOT supported on 99.99% of media players and has to be CPU Software decoded every time.
It's an out of Spec "release group" combo.
AMLogic hardware does not have enough CPU ponies to reliably software decode that content.
You need to buy Intel hardware or a NVIDIA Shield if you want reliability with that sort of CPU Software decoded video playback or Remux it.
Software decoded 720p 10-bit h264 works perfectly fine on S905 and (after several fixes by kszaq) also on S905X. I have a large collection of sample files and tested this extensively. 1080p, on the other hand, does not work properly as the CPUs hit 99% during decoding. But even this might change with optimization of ffmpeg software decode, as the ongoing work on encrypted streams shows.
The playback issues in the latest version are a regression. Maybe they are caused by the vsync change. I have trouble to reliably trigger it - the same files in the same order show problems after one reboot, but no after the next. Irritating.
