Use ffvp9 rather than libvpx for better performance?

Post by __NM64__ » 2016-09-14, 04:47

Firefox now uses ffvp9 rather than libvpx:
https://bugzilla.mozilla.org/show_bug.cgi?id=1210219 - (ffvp9) [meta] Ship ffpv9 on all desktop platforms
https://bugzilla.mozilla.org/show_bug.cgi?id=1214462 - Support ffmpeg on Windows

ffvp9 is known to be the fastest VP9 decoder and now that Firefox is using it, I was wondering if it'd make sense to use it in, say, Pale Moon 27?

If this enhancement is generally desired, it'll be a rather involved side project to tackle. See also the dependent bugs on bug #1214462 that would have to be ported + unknown related bugs.

Of note, ffvpx may be the fastest, but we're still a web browser, not a dedicated media player, and we do already have a good and running support for the lib as-published by the creator of the format, so actual format bugs should automatically be kept to a minimum that way (stability over performance).

I don't think any of our current team has time for this right now, but if some community members want to tackle this on a separate development branch, they are more than welcome to.

Using ffmpeg components as a front line for media will likely follow a similar (but less destructive and binary) progression as it has at Mozilla. This is more needed on linux and for mp4 decoding to shore up the deficits of gstreamer we have been seeing. That will have to be a necessary first step before we can consider it for Windows.

Though, I am wondering why when libvpx does fine on all operating systems. Guess it will have to be eval'd when/if we can make better use of it. Unless some magic patches pop up ;)
