Hi,
since this mesa change ( https://src.fedoraproject.org/rpms/mesa/c/94ef544b3f2125912dfbff4c6ef373fe49... https://src.fedoraproject.org/rpms/mesa/c/94ef544b3f2125912dfbff4c6ef373fe49806b52?branch=rawhide ) in F37 and rawhide, the mesa package lost support for vaapi accelerated encoding and decoding of h264, h265 and decoding of vc1 ( https://bugzilla.redhat.com/show_bug.cgi?id=2123998 https://bugzilla.redhat.com/show_bug.cgi?id=2123998 ).
It seems like a big regression from F36 for users with GPUs with open source drivers (mainly AMD, maybe nVidia/other non x86...), that affects common use-cases of Fedora Workstation, like watching videos, in-house game streaming, attending online meetings and many more.
I'd like to ask:
- Can somebody elaborate on reasons to change something that was working
in Fedora for some time already?
- Is there any short/mid/long term plan to improve the situation?
- Would it be possible to provide vaapi support at least as an rpmfusion
addon to alleviate the fallout in the short term?
Thanks!
While I can relate to the rationale to some extent, the amount of breakage caused by patents is slowly pushing me towards considering moving to a new distro. I am probably not the only one. This could be the proverbial straw breaking the camel's back. Recently, I experienced that the German AusweisApp, which already required entering the ID card PIN on the phone [1], has stopped working altogether [2]. This is due to hobbled openssl Fedora ships. There is no openssl-freeworld in RPM Fusion, probably because it would need to be rebuilt entirely.
I think we need to have the crypto function hobbling stuff re-evaluated entirely, it *might* no longer be needed (IANAL). Please raise it on the legal@ list.
For mesa, there is apparently also little interest in maintaining a mesa-freeworld package [3]. The discontent with ffmpeg moving to fedora a while ago also seems to have been primarily caused by the monolithic nature of ffmpeg. On the other hand, gstreamer plugins seem not to be a major problem.
As one of the ffmpeg maintainers, I'm actively working on workarounds for the problem. And I've talked to my counterparts in RPM Fusion about the issue as well. We're all trying to figure this out.
