SOLVED: Most compatible container and format

Well, tried some not played before tracks and for one got a remux, https://pastebin.com/raw/29UN0vHv for the test files (e01, e02, e03) the play starts right away (because I guess there's some cache somewhere, don't know where).

If I re enable Allow audio playback that requires transcoding and Allow video playback that requires transcoding, transcoding kicks in now with hardware acceleration (I guess because transcoding FPS went up to > 300 ) but de playback start delay persists (about 1 min in web player, didn't tested it in my other clients), logs https://pastebin.com/raw/d1m2CUXq and https://pastebin.com/raw/pYLKBk7J
