Below is the command that will display borderless video with the mplayer. The command below is specific to mplayer only.
mplayer -noborder "video.mp4" -geometry 2%:98% -zoom -x 325 -y 190 -vf crop=1280:544:0:88
Here ‘-noborder’ option turns off the border of th window.
-geometry : place the video window in xoffset: 2%, yoffset: 98% from top
-zoom : resizes the actual movie size to 325×190
-vf crop= : option removes the black borders that appear in some video. This needs to be tweaked video to video.
Use -vf cropdetect to detect what needs to be used to crop the black borders
To keep video, ‘always on top’ click the video windowand then hit capital ‘T.’
