As the title says, some video files wont play because the "video codec not supported". Issue is, they are supported... the video file is exactly the same as other videos i have, all of which i have encoded with x265/x265 (x265 files are also HDR). I have multiple files that wont play, one of them is from a dvd source, plays fine in vlc, and the other, an hevc source in hdr. The hevc will play in vlc too, but not very well, which i assume is because its using the cpu, not hardware decoding. Its also completely broken in terms of colour, im assuming because its hdr and vlc doesn't like that?? Its basically just completely green. I would like the play these in the native video app. Whats causing this?? I never had this issue on my galaxy s8.
Have you tried MX Player Shredderson?.. This brutal thing plays anything I have ever thrown at it??.. Not one 'video codec not supported' in sight. Ever. It is free but I bought the Pro version to get rid of the adverts. Well worth at least a look. Good luck regardless my friend.. 👍
