Re: [Bino-list] My tests: reaching for smooth playback of full-sbs HD video w/ subtitles

Hi Martin!

You're right, switching off the "inhibit the screensaver" option seems to
stop the hang ups.
Both Mplayer and VLC play the video + subtitles flawlessly.
Sorry about the subtitle parallax thing; I didn't see it! :)

Regards

Pedro

Does this go away if you switch off "inhibit the screensaver" in
Preferences->Fullscreen? It helps on my system.

Subtitle rendering happens in software (via LibASS) in screen resolution.
This should be fast enough, but I don't use subtitles myself so I seldom
test this.

Can Mplayer or VLC play the same half-width SBS video plus subtitles in your
setup without frame drops? If so, Bino clearly has a performance problem
somewhere that we should find and fix. If not, then the limiting factor is
likely LibASS (which mplayer and VLC also use), and there is little we can
do about that.

This is already available under Preferences->Current Video Settings.
