Today I tried to play a file on my Vero 4k that showed a lot of stutter. The debug info shows the decoder is ff-h264(SW) and a lot of dropped and skipped frames. See the file details below.
Is this simply a format the hardware decoder can’t handle? Is there anything I can do to make this file playback better on the Vero 4k?
Edit: Ok, so this file is 10 bit x264. From the poor results I gather the Vero 4k cannot decode this in hardware, and the CPU is not beefy enough to do it in software. CPU0-3 go to 100% and simply can’t keep up?
