Pale Moon forum

I am using the "pentium m" cpu.
Since my graphics card does not support video acceleration,
the video is always treated as software,
and I have not had enough cpu performance to use it.
And 480p video is also hard to play
However, if you use a player such as "mpv", the same video will run without a lag at 720p. Why do not you use a player like "mpv" as a backend when playing videos on a site like YouTube?

mpv uses the same libavcodec multimedia engine that Pale Moon does. HTML 5 just adds a lot of overhead that mpv does not have to deal with.

For what it's worth, with the current Debian mpv 0.27, I can have it open a blank window from the menu, then drag and drop a Youtube thumbnail from the browser into that window to play it. This requires that a recent youtube-dl also be installed.

There are also a multitude of other workarounds to use external instead of embedded video players in PM.
