Hello !
First, sorry for my english I'm a frog ! I'm a beginner with a rasberry pi 3B+ and Libreelec and not at all a geek (but using linux for years). If I can play the most of my video files on my tv not a 4K tv, it doesn't work for those that are 1080p H265 (often videos in the native language with subtitles). I tried to read, to search the net and to play with the settings without any success. After reading some things on the onternet I tried to search for the HEVC add-on. I only found HEIF add-on. I installed it anyway but without success. I would appreciate some help.
Thanks !
