Description of problem: Now that OpenH264 2.3.0 is out, ffmpeg needs to be rebuilt using its dlopen headers, since it uses a function that extracts the version string. Failing to do so will cause ffmpeg to crash when it tries to load the OpenH264 library. Version-Release number of selected component (if applicable): 5.1-1.fc37
Proposed as a Freeze Exception for 37-beta by Fedora user ngompa using the blocker tracking app because: This prevents programs using OpenH264 through ffmpeg from failing because of version mismatches.
FEDORA-2022-c6d88f0fa2 has been submitted as an update to Fedora 37. https://bodhi.fedoraproject.org/updates/FEDORA-2022-c6d88f0fa2
Isn't this update of ffmpeg also neccessary for Fedora 36 because it also has OpenH264 2.3.0 ?! I get errors playing some videos, for example from youtube or wetter.com.
(In reply to Edgar Hoch from comment #3) > Isn't this update of ffmpeg also neccessary for Fedora 36 because it also > has OpenH264 2.3.0 ?! Just a note: I tried to build ffmpeg-5.1.1 for Fedora 36 with mock with ffmpeg-5.1.1-1.fc37.src.rpm . It fails because configure requires libjxl >= 0.7.0. But libjxl version 0.7.0 exists currently only as release candidate. https://github.com/libjxl/libjxl/releases koji contains some builds of release candidates for Fedora 37. https://koji.fedoraproject.org/koji/packageinfo?packageID=33812 Hopefully there will be a release of libjxl before freeze of Fedora 37? Would it be possible that OpenH264 2.3.0 should not have been released for Fedora 36 because of these problems?

I didn't know OpenH264 2.3.0 was released to F36. It was only built for F37+ when I last looked. I'll have to prepare a separate update for ffmpeg 5.0 in F36, but yes, an update will be necessary.
OpenH264 contains an ABI break even though it did not bump soname. The only correct thing to do here is pull the update . Please don't rebuild ffmpeg against the new OpenH264: it's just going to create a bigger mess. There will be a corrected 2.3.1 release soon.

F36 needs to stay on 2.2.0 forever due to the ABI break, unless you're prepared to rebuild *everything* that depends on it. Then again, that's what we'll need to do with F37 anyway....
Michael, this isn't helping at all... Could you talk to me please next time instead of going and asking people to pull updates and telling people to not bother fixing things? Neal: Yes, would be good if you could update ffmpeg on F36 as well for the new openh264 release. Sorry, I didn't realize that ffmpeg is dlopening openh264 and thought that all of the openh264 ABI consumers that we have (gstreamer1-plugin-openh264 and mozilla-openh264) came from the same SRPM as openh264 and get automatically rebuilt whenever openh264 gets updated because of that. Mea culpa! I'll look out to make sure we get ffmpeg updated together with openh264 next time.

An ABI break without a soname bump is never acceptable: it's going to cause apps to start crashing or misbehaving. This goes beyond our Firefox/GStreamer/ffmpeg plugins. In the upstream bug I posted a Debian codesearch result showing all the various places where the affected struct is allocated on the stack in a bunch of different applications.
And unfortunately this did hit F36, so now we have a big mess. :(
