Question about ffmpeg slot based support
......AND
Fixes for several packages with <ffmpeg-5 dependency problem.
-----------------------------------------------------
I've been dealing with ffmpeg4 API changes and compatibility issues with many packages while trying to upgrade to ffmpeg-5/ffmpeg-6.
(Which I need for zoneminder which as of now requires ffmpeg-5, in its latest build)
I think I'm gonna have to accept many packages will require <ffmpeg5 support due to age.
Is it possible to install ffmpeg via the slot system?
- So have both ffmpeg:4 and ffmpeg:5 or ffmpeg:6 installed simultaneously?
- I've read that's how some distributions have handled the issue, packages such as VLC won't built with vaapi from ffmpeg
(such as FreeBSD)
As far as VLC & <ffmpeg-5
Solution: I simply wrote a custom VLC 3.0.18-r4 w/ all #<ffmpeg-5 blocks removed, and built w/o vaapi.
-- vaapi specific library was removed in ffmpeg-5 and is what is causing packages to break, lib...... you can easily find the proper lib name.
As far as Handbrake & <ffmpeg-5
Solution: I simply wrote a handbrake 1.6.1 ebuild and the latest release built just fine with ffmpeg-5 on the system.
Transcode 1.1.7 & <ffmpeg-5 .ebuild took a bit more work, keeps trying to downgrade ffmpeg like many others but the fix was more challenging,
-- Following the instructions on Transcode's website it built just fine.
Solution: I wrote a rough ebuild named it Transcode 1.1.7-r7
- simple removed the <ffmpeg-5 blocks
- only apply the single patch from their website
- have the src_configure build as their website says --disable--ffmpeg
For the sake of time to get it to build as an ebuild into the system, here is a very sloppy ebuild that includes the solution.
- I removed almost all the USE functions (sloppy, a Vanilla style approach)
Partial code from custom .ebuild
The goal of my .ebuild (which I haven't written one in years), was to build Vanilla style.
The only thing needed for it to build was one patch from their website.
| Code: | | transcode-1.1.7-gcc10_fix-1.patch |
Which I downloaded and manually placed into the /var/db/repos/awalp/media-video/transcode/files/ directory.
and
building it with recommended configuration after patch.
| Code: | --enable-alsa
--enable-libmpeg2
--disable-ffmpeg |
| Code: |
PATCHES=(
[b] "${FILESDIR}"/${P}-gcc10_fix-1.patch[/b]
)
src_prepare() {
default
eautoreconf
}
rc_configure() {
local myeconfargs=(
............
--enable-alsa
--enable-libmpeg2
--disable-ffmpeg
...........
${myconf}
)
econf "${myeconfargs[@]}"
}
|
in the configure.
I removed all ffmpeg related stuff,
I realize I also probably removed most the USE flags functionality,
though I thought I'd post it to help get the ebuild fixed, someone/maintainer could integrate the solution better.
for the sake of time I just needed to get it built.

Full ebuild for Transcode-1.1.7 (very sloppy USE functionality mostly not working)......

Again, this will take a lot of work and may not be possible with older packages.
Can ffmpeg be installed w/ a slot based approach?
ffmpeg:4 simultaneously as ffmpeg:5 or ffmpeg:6
FreeBSD among other distros uses an ffmpeg-4 w/ ffmpeg-6 as their "dirty" solution. |

It is often even more work in order to make slots on libraries because of:
- Each slot must not install to the same file locations as another slot in addition to other packages
- The build systems of dependent packages must know how to access the different locations
Because of #2, this often makes it lots of work for many, many package maintainers to get it working in the first place when it is not natural to do so in the library upstream |

Why do you need to do this? Just set USE=-vaapi, or use 9999 (which has it fixed, it's just too hard to backport to 3.x). |

When vaapi is needed and when isn't?
Many thanks.
Alias, when can I live well without if watching film or videos.
EDIT: without vaapi I could update everything, WOW. Maybe it's worth it
