Long Overdue (years) Not Fixed Error

[Playerror]

Hi,

Thanks for fixing slider/search for mpv 0.30.x.

The long overdue error that nobody has yet addressed is as follow:

AUTOLOAD subtitles:

1.Start movie/video
2. Folder with video contanites ".txt" subtitles
3. Subtitle file has THE SAME NAME as video
4. Subtitle are NOT autoloaded
5. ALL OPTIONS in "preferences" checked.
6. Subtitle regardless of any options (UTF, non utf "cp-windows" , "try to detec language, same as movie and others, select first...) have to be manually loaded.

Error: if SMPlayer is primarily coded for Windows or Apple, other systems have not been addressed (I suspect this error is probably non existent on M$ or Apple- I don't have any of those non GPL crap in my home). Please start using non M$ systems to code for SMPlayer.

Additional Info:
system (own distro with OpenRC, udev rules for I/O scheduler [bfq...], zswap, amazing font rendering, full vsync to blank, Intel Management Engine - completely turned off, arch based)
mpv: 0.30.0
Smplayer: Version: 19.10.0 (revision 9238)
rest (non relevant):
libavutil 56.31.100
libavcodec 58.54.100
libavformat 58.29.100
libswscale 5.5.100
libavfilter 7.57.100
libswresample 3.5.100
ffmpeg version: n4.2.1
Zero errors in log.
Hope you will finally look into it under non windows system.

The subtitles are autoloaded by mplayer/mpv. It seems mplayer autoloads *.txt files but mpv doesn't.
