ffmpeg6 split
[ci skip]


#### Testing the changes

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

main testing has been vaapi in Firefox Nightly and enc/dec in Shotcut on Intel A770

#### 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

`libavresample` is deprecated, but marked as a dependency when trying to build other packages and install `ffmpeg`(6). I think the right way to handle this is make a meta package and the add to removals?


##### Commit naming / misc

~~Commits are 'dirty' right now, running with [gstreamer 1.22.1 updates](https://github.com/void-linux/void-packages/pull/42861) and [Intel OpenCL](https://github.com/void-linux/void-packages/pull/43084). This will also make [intel packages pr](https://github.com/void-linux/void-packages/pull/41132) obsolete.~~ (see Requirements below)

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.

~~This updates QT5 which looks like it is usually hosted by Johnny. Not sure if there's any reason to stay there or these sources are fine.~~ Using qt5.15.11 now, revbumps and some patches.

##### STILL FFMPEG4

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

- attract (multiple patches in master)
- ~~audacity (https://github.com/audacity/audacity/issues/2305 and https://sourceforge.net/p/portmedia/wiki/portsmf/ is 'beta')~~ (updated to 3.x, compiles with ffmpeg6)
- ccextractor (master patches? no release)
- vice
- kodi
- mlt (only dep left is flowblade)
- ~~synfig (mlt)~~ (work with mlt7, bump synfigstudio)
- tvheadend
- ssr
- ~~spek-alternative~~ (replace with spek-x)
- ppsspp
- olive
- moc
- mediastreamer
- libextractor
- idjc
- hedgewars
- ~~ffmpegthumbnailer~~ (patches for moviedecoder.xxx files)
- ~~ffmpegthumbs~~ (latest compiles)
- deadbeef
- ~~omxplayer~~ (package removed, deprecated in favor of vlc)
- qtav (fork has ffmpeg 5 patch - https://github.com/cmguo/QtAV)
- `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`)


##### HAVE NOT BUILT YET

- ~~omxplayer (rpi only? ffmpeg4)~~ (removed)
- kodi (big, but ffmpeg4)


##### UPDATED (for ffmpeg6)

- ~~blender: update to 3.5.1~~ ~~will be revbump with~~ https://github.com/void-linux/void-packages/pull/43992
- unpaper: update to 7.0.0.
- guvcview: update to 2.0.8.

- ~~python3-pyside2: update to 5.15.8 (patch)~~ updated by another PR to 5.15.10

##### Requirements

- ~~[gstreamer 1.22.2](https://github.com/void-linux/void-packages/pull/42861)~~ - a few packages use ffmpeg-devel and require a revbump

- ~~[Intel Packages](https://github.com/void-linux/void-packages/pull/41132) [Intel Packages v2](https://github.com/void-linux/void-packages/pull/47330) - ffmpeg4 uses different libraries than 6 (libmfx / Intel-MediaSDK vs only oneVPL that Intel is moving to), both are included here~~. Using replacement oneVPL from OBS update.

- ~~[shotcut 23.05.14](https://github.com/void-linux/void-packages/pull/44260)~~

- https://github.com/void-linux/void-packages/pull/44781 will remove from this PR
