hey guys, so i’m still having issues with firefox and video playback. i’ve done all the suggestions in this thread and have gotten videos to work, however the videos stutter every 10 seconds or so. like they freeze for a few seconds then catch back up while the audio keeps playing – making videos essentially unwatchable on firefox.
does anyone use firefox and have this issue? i’ve moved over to using brave which has no issues, but i’d really prefer to be using firefox but the video playback is killing me.
i’m on the latest update of fedora 39, 3.03 bios, and i’ve tried the flatpak and rpm version of firefox and they both have the same issue.
To expose the various capabilities via vaapi for encode/decode - fedora strips patent encumbered bits from mesa by default. IME people forget to run the dnf swap bits after adding rpmfusion .
You can check what is exposed by installing libva-utils and running vainfo
I’m having an with Youtube videos in Firefox on Fedora 39, 6.5.11 Kernel (happened on previous kernels as well), 3.03 BIOS. Audio plays smooth, but video temporarily freezes or stutters for a bit then catches back up and plays smoothly for a bit. This happens at random, inconsistent intervals. Sometimes is merely and annoyance, sometimes it’s to the point of making the video completely unwatchable. It doesn’t seem resolution dependent. This will sometimes happen at 720p resolution and sometimes even 4K60 videos will play smooth. But that’s not the main oddity to this issue. Videos play fine with wired headphones and when using the inbuilt speakers. But if I use bluetooth earbuds, this video freezing and stuttering issue occurs. I can disconnect my bluetooth earbuds and the video will start playing smooth. Re-connect my bluetooth earbuds and the video will start getting choppy again.
This issue is unchanged whether I have the system in Power Saver, Balanced, or Performance modes. Also, I have the GPU set to “game mode” in the BIOS. I haven’t seen any graphical glitches or issues some people have had, just this video stuttering issue with videos while using bluetooth earbuds. This happens on battery and when plugged into a charger.
@BigT ; yup I noticed this also with the fc39 kernel; also happens in ublue/silverblue as well as workstation and in Plasma or Gnome; i’ve moved to using rawhide over the weekend and will be watching over the next couple of days for it.
So on rawhide I don’t get the stuttering; but I do get a lot of these familar messages (I see these on my rdna3 5950x quite often with various combinations of kernel/mesa/firefox/chrome)
MediaPD~oder #3[29662]: segfault at 60 ip 00007ff578b4901f sp 00007ff59f9fcd40 error 4 in libLLVM-17.so[7ff576949000+384c000] likely on CPU 9 (core 4, socket 0)
It’s something to do with the Mediapipeline decoder bits and it’s interaction with the rest of the system. I’ve never been able to root cause it (I thought it was my 5950x being PBO2 clocked/RAM/Mobo - but it’s definately software related rather than hardware after bisecting a heap of those things previously on my workstation.
Also the ec_cros patches that were added sometime back to mainline for the Intel FW do not work for the AMD EC controller and there needs patches/documentaiton for the ec controller to be made available and added to a patchset. There is nothing in any of the various kernel trees i’ve diff’d that deal with the EC controller for the AMD. This includes the various ec_tool efi and userspace libs throwing invalid checksums when querying the AMD ec.
Can someone running the OEM Kernel that people mention for ubuntu let me know if ec_cros_lpc loads ; and if so where the source tree is so I can see what if any patches were made for the amd ec controller in that kernel.
And you should then get errors from the PD.auto probe (which needs a fixup which doesn’t currently exist). Am not sure what needs to happen in the auto probe ; there seems to be some discussion/patches which may be related to how auto probing happens. But this likely needs flagging up the poll to people more familar than I. Perhaps @DHowett ? I see a thread for the Intel Framework which mentions similar output - so this may just be overly verbose output that shouldn’t appear in dmesg.

The persistent probe and ACK failures around ucsi_acpi
and the ambient light sensor, and some designware i2c errors (which appear mostly benign and related to state saving where the last touch position was during resum/cold boot). Are the last remaining bits that appear broken on the amd framework.
In the thread about the RTC advancing/doubling while in s2idle, I read between the lines that addressing this EC driver issue would also address this problem by removing a race condition when reading the RTC on resume. Am I assuming this correctly?
I still get the warningwith the ec patch applied. But I didn’t see bad behaviour with 6.7 rawhide kernels prior to addingit, sohave it added as a precaution.
After updating with dnf which installed a new kernel, I would expect the new kernel to be the default in grub, however, 6.5.6 remains the default. Reading the docs, it looks like it should automatically be updated. On further investigation, the /etc/sysconfig/kernel is missing from my system. Is this a bug in F39? Would adding the file solve the issue or is there something else going on?
