There's a closed pull request on the void-packages repository

draft: ffmpeg5 split
https://github.com/void-linux/void-packages/pull/42936

Description:
[ci skip]

#### Testing the changes

- I tested the changes in this PR: **YES**

~~I have conflicting changes from [intel packages](https://github.com/void-linux/void-packages/pull/41132) and don't want to mess with my system. If it makes sense I'll move these changes here like I originally intended. ffmpeg5 makes Intel vaapi easier and only rely on oneVPL iirc.~~

I do not use 80%+ of these packages. I may be able to run Blender, and I use shotcut.


#### New package

- This new package conforms to the [package requirements](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#package-requirements): **YES**



#### Local build testing

- I built this PR locally for my native architecture, **x86_64**


#### Discussion

Continuation of https://github.com/void-linux/void-packages/pull/36315 - thx tibequadorian :)

It was suggested to make `ffmpeg` version 5 and 'copy' (create a new?) `ffmpeg4` package, and that seems to work well.

As stated, I haven't and probably won't test most of these packages, hoping for others to voice in on what's working. 

A few months back (and now) afaict everything has been compiling with ffmpeg5 except for the few problem packages still using ffmpeg4 (below). Can add to the ffmpeg4 list as a incompatible package is found.

`libavresample` is deprecated, but marked as a dependency when trying to build other packages and install `ffmpeg`(5). I think the right way to handle this is make a meta package and the add to removals?

[gstreamer 1.22.1 updates](https://github.com/void-linux/void-packages/pull/42861) could go before this

##### Commit naming / misc

~~`ffpmeg4` isn't "new", not sure what the commit messages should be really for the 4 and 5 split. Additionally xlint complains about `ffmpeg4` revision being 3 and not 1 because it's a "new" package, I assume that's right but not sure.~~

~~Not sure how commits should be separated. ffmpeg4/5 could be split and all the rev bumps included (otherwise it's over 100 commits). opencv was updated to 4.7.0 for ffmpeg5 so I figured that should be a separate commit?~~

I wouldn't mind moving the [intel packages](https://github.com/void-linux/void-packages/pull/41132) into here under another commit. That just got a potential fix that may allow merging but I imagine moving to ffmpeg5 will change and even remove some of those packages. (I won't really test these changes without Intel vaapi either way.)

Maintainer for previous ffmpeg(4) was orphaned, I can put my name in there if that matters, though I don't exactly see myself keeping up on ffmpeg.


##### STILL FFMPEG4

These are a mix of emulators, games and/or older packages.

- attract (multiple patches in master)
- audacity  (3.2.x should work but void is missing some libs? vst3sdk?)
- ccextractor (master patches? no release)
- vice
- mlt
- synfig (mlt)
- tvheadend
- ssr
- spek-alternative
- ppsspp
- olive
- moc
- mediastreamer
- libextractor
- idjc
- hedgewars
- ~~handbrake~~
- ffmpegthumbnailer
- ffmpegthumbs
- deadbeef
- omxplayer
- qtav (fork has ffmpeg 5 patch - https://github.com/cmguo/QtAV)
- ~~qt5-webengine~~ (need patch and version bump. ~~may work? if not gentoo has a patch? https://bugs.gentoo.org/831487~~)
- `vlc` (vlc4 will support ffmpeg5, there's a patch to build 3.x with ffmpeg5 but it will lack vaapi)
- `osg` (OpenSceneGraph plus `xine-lib`)
- `ytmdl` ? not sure but it uses `python3-ffmpeg-python` which being 6-8yr old I imagine is ffmpeg4
