Playback black screen, sounds working

[Geminiatack27 1]

Hi, I have a weird problem on my tablet Samsung A8, while playback a hevc mkv with Ffmpeg as rendered I get a weird black screen and glitches with the aspect ration on Auto, i have to watch on cover or fill, other series on other formats and codecs are working fine. Also I searched for an option to have a fixed aspect ratio all the time but I could not find it if it exists and every episode I have to wait a sec and do this, also on auto aspect ration, the image gets Better in let's say 30 seconds but it plays one frame, if I touch the screen it updates. I don't know if it is 100% related to the aspect ratio. More weirdly the cree capture on the device captures normal video playing with no problem, it is just what I am seeing. I uploaded a video made with my phone I hope this helps, or at least make a option in playback for a fixed aspect ration. Thank you
