Would be nice to be able to set default playback speed of video, I like to watch at 2x the speed.
Also Speed up/down should be configurable, I like steps of 0.25 vs the default 10%.
Currently I am constantly having to speed up each clips by hitting the speed up multiple times and this just get annoying real fast. A better would be to keep the playback speed last use for the next clip or video playing back.
Go to preferences -> advanced -> mplayer/mpv and type this line in the options field:
--speed=2
The option errors if entered as, "--speed=2", I think it should be. "-speed 2".
Still this fails to set the speed for me to 2 on staerup. I closed the app and started it again, still playback speed is 1.
-speed 2 is for mplayer, --speed=2 is for mpv
I can't reproduce your problem with the startup speed, using that option makes all videos to play at 2x.
I am using Linux Kubuntu 18.04
