HEVC support

[Austin_Conlon]

Would like to see this!

@wutongtaiwanwhere can i enable it, im using the latest 131.0 nightly and https://html5test.co/ tells me it doesn't support it

[wutongtaiwan]

@earthjasonlinI don't know.It should be that Firefox does not have this feature yet

Hi @wutongtaiwan--apologies for the delay, I can answer a couple of your questions now and follow up on the third one after checking with my engineers.

1. HEVC support (for DRM video content only) should be available in Nightly 130. If you are encountering any issues, please file a bug on Bugzilla.com--I'm flagging the issue @earthjasonlin brought up to my engineers and will follow up with a clarification as soon as I can.  
2. We're still evaluating usage of HEVC for non-DRM content--if it becomes compelling enough, we will prioritize it. We have the technical foundation for support, but we have not committed to a specific release at the moment.

We are working with partners to determine timing for rolling out support to our release channel, and I will follow up here once we confirm.

@itskaren I'm using nightly131. Please is there a way to verify that hevc is turned on

Hello,

Just created an account to share my findings. I'm currently running version 130.0.

Go to the web page "about:config" in your Firefox. In the search bar at the top, type "hevc". It should find "media.wmf.hevc.enabled". @wutongtaiwan 

If enabled, you should have a "1" at the end of that line. If you have a "0", "hevc" is disabled.
If you have it on "0", simply double-click the "0", then type in "1" and then press Enter.

Enjoy.

@itskarenI would REALLY like to see HEVC for non-DRM content. Use-case: Ubiquiti now supports HEVC for their video camera software. If I enable HEVC for my cameras, now I can't use firefox anymore to watch my cameras. I don't want to have to switch browsers just for that. Start a GoFundMe or whatever!

Not able to see that flag in Firefox Nightly build 133.0a1 to enable the flag.

I have 133.0a1 (2024-10-05) MacOS and nothing found by `hevc` in about:config . ☹️

Please support hevc, be it for ubiquity, plex, jellyfin, etc

I'm sorry, but how can DRM stuff be done before the, I imagine much simpler, non-DRM implementation? Isn't DRM video just video + some kind of encryption on top? Like I'd assume the plain video tag with no DRM is not just easier but one of the steps to getting DRM video to work??

Hi folks! This is hot off the press, but we just made the decision to build general HEVC support in Firefox (beyond the DRM support we already have now). Stay tuned for developments - we hope to ship it to you in a couple of releases.

Please note that this is for a Windows implementation, but we plan to kick off investigating ways to support HEVC on macOS and Linux/Android early next year.

Thank you all for sharing the sites you visit and the specific ways you use general HEVC - it helped us build our case to get this work resourced. 🙂

@itskarenthis is great news! Hot off the press - I'm making a donation to the Mozilla foundation. Keep up the great work!

[hungarianhc]

Oh wait oh noooooo it's Windows-only for now. I'm Mac / Linux... LOL. Okay... As long as it's on the roadmap, I'm good. Thank you!!

This is now 'In development' — check out @itskaren's recent comment in the thread for more info.

Thanks again for your role in pushing this work forward 💪
