mpv is the default player for latest smplayer. Since mplayer didnt work after compiling its latest version from source (see my previous post), I decided to recompile mpv.
git clone https://github.com/mpv-player/mpv-build.git cd mpv-build/ sudo apt install libfribidi-dev libfribidi-bin yasm ./rebuild -j4 sudo ./install
Note: There may be other dependencies.
Thus I upgraded my mpv 0.14.0 to 0.25.0-26-gde225e3.
