From a641e629591d68bd3edd99bddec623dc31295f6b Mon Sep 17 00:00:00 2001
From: Kalev Lember <klember@redhat.com>
Date: Wed, 6 Dec 2023 14:37:34 +0100
Subject: [PATCH] lavc/libopenh264: Drop openh264 runtime version checks
Years ago, openh264 releases often changed their ABI without changing
the library soname. To avoid running into ABI issues, a version check
was added to lavc libopenh264 code to error out at runtime in case the
build time and runtime openh264 versions don't match.
This should no longer be an issue with newer openh264 releases and we
can drop the runtime version check and rely on upstream doing the right
thing and bump the library soname if the ABI changes, similar to how
other libraries are consumed in ffmpeg.
Almost all major distributions now include openh264 and this means there
are more eyes on ABI changes and issues are discovered and reported
quickly. See e.g. https://github.com/cisco/openh264/issues/3564 where an
ABI issue was quickly discovered and fixed.
Relaxing the check allows downstream distributions to build ffmpeg
against e.g. openh264 2.3.1 and ship an update to ABI-compatible
openh264 2.4.0, without needing to coordinate a lock step update between
ffmpeg and openh264 (which can be difficult if openh264 is distributed
by Cisco and ffmpeg comes from the distro, such as is the case for
Fedora).

# FFMPEG
FFmpeg is a multimedia framework, able to decode, encode, transcode, mux,
demux, stream, filter and play pretty much anything that humans and machines
have created. It supports the most obscure ancient formats up to the cutting
edge. No matter if they were designed by some standards committee, the
community or a corporation.
## Creating the 'free' tarball
1. Update the `Version` in the spec file.
2. Set the `Release` to 0 in the spec file.
3. Set `pkg_suffix` to `%nil`
4. Do a full build locally: `fedpkg mockbuild --with full_build`
5. Run `./ffmpeg_update_free_sources.sh results_ffmpeg/5.0/0.fc35/build.log`
This will update the `ffmpeg_free_sources` file list.
Note that header files will need to be manually added
to the `ffmpeg_free_sources` file list.
6. Run `./ffmpeg_gen_free_tarball.sh` to create the tarball.
7. Set `pkg_suffix` to `-free` again
8. Set the `Release` to 1 in the spec file.
9. Do a scratch build.
OR
1. Edit `ffmpeg_free_sources` and add missing files
2. Run `./ffmpeg_gen_free_tarball.sh` to create the tarball.
3. Do a scratch build.

From 1f48740db0dda8d6ec1b97a7f4a794e381a65636 Mon Sep 17 00:00:00 2001
From: Neal Gompa <ngompa@fedoraproject.org>
Date: Wed, 12 Oct 2022 09:41:27 -0400
Subject: [PATCH] avcodec/openh264: Add the ability to dlopen() OpenH264
We can't directly depend on OpenH264, but we can weakly link to it
and gracefully expose the capability.
