I don’t know what to do. I’ve tried searching through google and all the answers don’t seem to work. When I use Firefox (this is librewolf but it’s the same on Firefox), games like Tetr.io or Friday Night Funkin lag real bad but they’re buttery smooth on Chrome or Chromium. I have an iGPU and a “Cedar” AMD GPU according to lspci. Someone please help me, I don’t wanna use Chromium just to get good performance. Please tell me if I need to provide more information.
- Firefox Hardware video acceleration - If hardware video acceleration is blocked with error code FEATURE_HARDWARE_VIDEO_DECODING_DISABLE or FEATURE_FAILURE_VIDEO_DECODING_TEST_FAILED in about:support, you can override it with media.hardware-video-decoding.force-enabled=true. See [10] for more information. Alternatively, you can install firefox-vaapiAUR. - Also make sure that in - about:support- Compositingin the Features table under Graphics is set to- WebRenderif it is not than set- gfx.webrender.allin- about:configto- true.- I had the same issue but I have a NVIDIA gpu. but I just had to install libva-nvidia-driver and edit Kernel parameters and Environment Variables . I got this to work with both Firefox and Librewolf but only some video codecs. - note i have 1080ti so i don’t have hardware acceleration for av1. also the only time a problem when I turn off hardware decdoing on firefox is when I watch a HEVC stream on twitch for some reason i get drop frames every second. - Firefox V137.0 Linux - Codec Name - Software Decoding - Hardware Decoding - H264 - Supported - Supported - VP9 - Supported - Supported - VP8 - Supported - Unsupported - AV1 - Supported - Unsupported - HEVC - Supported - Supported - AAC - Supported - Unsupported - MP3 - Supported - Unsupported - Opus - Supported - Unsupported - Vorbis - Supported - Unsupported - FLAC - Supported - Unsupported - Wave - Supported - Unsupported - Librewolf V136.0.4 (HEVC decoding is only add support on Firefox 137.0 on linux) - Codec Name - Software Decoding - Hardware Decoding - H264 - Supported - Supported - VP9 - Supported - Supported - VP8 - Supported - Unsupported - AV1 - Supported - Unsupported - HEVC - Unsupported - Unsupported - AAC - Supported - Unsupported - MP3 - Supported - Unsupported - Opus - Supported - Unsupported - Vorbis - Supported - Unsupported - FLAC - Supported - Unsupported - Wave - Supported - Unsupported - Did all that but it’s still the same. I really don’t know what’s the root cause of this. - I sure you have but have you tried checking the out put of - vainfoArch wiki since Firefox only supports Hardware acceleration with VA-API.- libva info: VA-API version 1.22.0 libva info: Trying to open /usr/lib64/dri-nonfree/iHD_drv_video.so libva info: Trying to open /usr/lib64/dri-freeworld/iHD_drv_video.so libva info: Trying to open /usr/lib64/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_22 libva error: /usr/lib64/dri/iHD_drv_video.so init failed libva info: va_openDriver() returns 1 libva info: Trying to open /usr/lib64/dri-nonfree/i965_drv_video.so libva info: Trying to open /usr/lib64/dri-freeworld/i965_drv_video.so libva info: Trying to open /usr/lib64/dri/i965_drv_video.so libva info: va_openDriver() returns -1 vaInitialize failed with error code -1 (unknown libva error),exit``` This is what I got, I still dunno what it means.- which gen is your igpu? Older intel igpus need - libva-intel-driverpkg installed (on Arch, not sure whats the Fedora equivalent) and the env variable- LIBVA_DRIVER_NAMEset to- i965.- See also https://wiki.archlinux.org/title/Hardware_video_acceleration#VA-API_drivers. - According to fastfetch it’s a “Intel Xeon E3-1200 v2/3rd gen core processor” - When I tried to run “LIBVA_DRIVER_NAME=i965 firefox” it spat out “restorecon: SELinux: Could not get canonical path for /home/[myusername]/.mozilla/firefox//gmp-widevinecdm/ restorecon: No such file or directory.” 
 
 
 
 
 
- deleted by creator - Fedora, but I had the same problem on Arch. - Currently I have it installed through Flatpak but I have the same problem with distro package. - deleted by creator - Yes. 
- I have the same exact set up on my Thinkpad x240 and it’s running smooth on Firefox so I dunno… I’m ripping my hair out over this tbh. 
 
 
 
- I don’t understand why this stuff isn’t enabled by default on Linux, it’s such a detriment to new users when super basic features don’t work out of the box. 
- It’s for fedora but maybe this link could help : https://fostips.com/hardware-acceleration-video-fedora/?amp=1 
 It did for me. I replaced mesa drivers for my amd card.
