I'm thinking too about a transparent toolbar that contain all required functions, it will disappear once mouse is on the bottom edge of the screen

FFMPEG version 5.1.2 should be able to play all those video codecs, but not sure about h.265

Most Video codecs bring back Y,U,V arrays for each pixel instead of R,G,B. (requiring a conversion later)
but depends on the video file, it could return :
- full Y,U,V arrays for each pixel "YUV444"
- full Y array, but half arrays for U,V "YUV422"
- full Y array and a quarter arrays U,V "YUV420"

to increase rendering quality, instead of taking the missing U,V from the nearest pixel, we do an interpolation between the surrounding pixels, creating then a full YUV44 arrays.
According to my tests the quality gain is very little if none, maybe because of the 16bpp color space.
