Hardware video decoding is broken in flatpak Firefox (Intel GPU) #1409
Comments

Are you using fedora's FF Flatpak or the one from mozilla?
https://src.fedoraproject.org/flatpaks/firefox Here is the FF from Mozilla. I wonder if you might get better luck w/ the Mozilla one? |
|
I switched from the Flathub version to the Fedora one. Making my host libraries available in the flatpak and playing around a bit with The Fedora version is worse than the Flathub one, because the software decoder can only play YouTube videos at ~1fps. So I switched back to the Flathub version (that I had originally), this way the software decoding works. |

Yeah this issue has nothing to do with the Fedora flatpak, is that screenshot from a ublue system? I haven't been able to reproduce on my intel systems, the hwaccel is working on all of them ootb, so maybe it's something else. |
|
@tamasd I suggest to update your Firefox, this seemed to be broader issue that was fixed in version 127.0.2. I have this version from Flatpak, don't see any issues. |
|
I checked with 127.0.2, unfortunately I have the same error :( I think this will be resolved temporarly when the new freedesktop flatpak platform will be released (in a month or so) and a new firefox version will be released using that. However, it might come back when a new Fedora will be released, because the rpm fusion intel driver package is built against Fedora's libraries and not the standard platform. |

Should we give this a tag "unable to confirm*" and close? What do we need to confirm root cause? |

I have Firefox 128.0.3 now, the situation is not changed. Can I get a confirmation from someone who has Intel iGPU and the Flatpak Firefox that on the |

Reopening since this is still affecting people. |

@tamasd First, thank you for your issue and for the detailed troubleshooting, that's very helpful! TL;DR - I believe things should be working well now, at least on intel. Here's what I'm seeing on a recent bluefin image ( ghcr.io/ublue-os/bluefin-dx-nvidia:stable Version: 40.20241101.0 )... So Fedora 40 on a hybrid intel+nvidia laptop running flatpak mozilla firefox version 132.
I have all default settings for Firefox in Flatseal, nothing custom. I tried to set old "forced" config options to defaults in
Within a On host using flatpak binary: Nvidia vaapi does fail, but I haven't dug in to that as I don't want to use it and it does show as supported in host. |

I have Firefox 132.0 and the system is on the @bsherman what are your flatpak info and overrides? Mine are: $ flatpak info org.mozilla.firefox

In this possibly related ticket, the solution was to modify the intel driver GUC parameter. I wonder if that may help for you, depending on your specific hardware. |
|
Also, this PR just merged, #1876 It will set I have found this is needed on AMD, I don't think it will help on Intel, especially if the problem is GUC related, but it's worth mentioning. Tomorrow's Bluefin builds will have this. |
I installed Bluefin on my laptop and noticed that YouTube videos make my laptop quite warm. I started to look into it, and I saw that Firefox can't use hardware acceleration for video decoding.
First I checked the output of
vainfo:The
about:supportpage says thatHARDWARE_VIDEO_DECODINGruntime is unavailable because it got force disabled byglxInfowith the failure codeFEATURE_FAILURE_VIDEO_DECODING_TEST_FAILED.After reading forum posts and tutorials, I set environment variables in Flatseal:
MOZ_DISABLE_RDD_SANDBOX=1MOZ_ENABLE_WAYLAND=1LIBVA_MESSAGING_LEVEL=1LIBVA_DRIVERS_PATH=/run/host/usr/lib64/driLIBVA_DRIVER_NAME=iHD<- this is the appropriate driver for my iGPUI enabled GPU acceleration in the Devices section.
I also set a dozen configurations in
about:configin various combinations but nothing worked.So I looked into what Firefox is actually doing when checking the hardware support. Turns out there is a small program called
vaapitest. Running this inside the flatpak container revealed the actual problem:Running it outside of the flatpak works:
I checked the
libstdc++.so.6file for the CXXABI support and it has it:The one in the flatpak (coming from
org.freedesktop.Platform) does not:I think the problem is that the
intel-media-driverpackage from RPMFusion is compiled against a newerlibstdc++while the flatpak platform ships an older one.The text was updated successfully, but these errors were encountered:
