From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This is like the 6th time they've claimed this. I was attacked before for saying this wasn't working correctly.
Weird, it's been working for me for a while. I just need to manually set "media.ffmpeg.vaapi.enabled" to true in about:config.

That's strange, I'm almost certain my desktop's Firefox doesn't have this (AMD GPU) while my laptop's Firefox does (Nvidea GPU)
I just need to manually set
media.ffmpeg.vaapi.enabledto true in about:config
OK yeah that's something 99% of even Firefox users aren't going to know... Bookmarking this to try when I'm back home!
I could have sworn they did this already a while back.
I still can't play my videos on Firefox without transcoding them, so I honestly hope they get it right this time.
They don't have mkv support by the way, that won't ever work in Firefox. Are you sure you're not trying to play mkv files?
Of course I am, there's no way I can escape mkvs. It's not too bad if it doesn't have to transcode the actual video stream, but having to burn in subtitles is a common issue 😭
Could be wrong, but it's not about working but rather that it is now enabled by default.
Which may haven't been the case, I suppose?
Fedora's repo build has had this turned on for literally years
Fedora's repo lacks H264 support for AMD out of the box though.
Unless you're on the KDE spin, which offers you the choice to install the codecs as a post-install step (iirc?).
It has been a while since I reinstalled Fedora KDE but I don't think it swaps mesa/ffmpeg/gstreamer to the freeworld version automatically, it just enables the repository for it.
I'd rather have software decode of h.264 on par with Chromium. As it is I can't watch Twitch on my laptop in Firefox.
Isn't that just because Twitch doesn't allow you to browse it using Firefox though?
No. The only Firefox problem I have on Twitch is that any video above 720p begins to stutter. And 720p makes my laptop work like crazy. Same on YouTube when I encounter an old video with h.264. It has already been reported. I just have to wait until someone fixes it.
Twitch is veeeeryyy slooowlyyy transitioning to AV1 for their livestreams, maybe that'll work better than h.264 whenever it's ready.
Fair enough. I've tried using twitch on my Fedora laptop with FF and I get blocked out by their browser message so I assumed that they were restricting access to chromium only.
What about Intel? I’ve been trying to get hardware acceleration on Firefox all day yesterday with no luck.
It's been working fine since a couple years ago on Intel. It works on my Intel machines with both old and recent cpus

The article mentions AMD GPU so I am assuming they are talking about Intel arc GPU
VAAPI works on the integrated GPUs as well. There's a table of supported codecs here: https://wiki.archlinux.org/title/Hardware_video_acceleration#Comparison_tables
Unfortunately they never bothered to get things integrated into Mesa and they have 2 different packages.
its already working for me, and was for a long time.
