use custom ffmpeg build on MS Windows #3166

totaam · 2021-06-13T03:44:53Z

The default one from MSYS2 brings in too many libraries.
The latest dependencies add dozens of megabytes to the installer for things we will never use.

Maybe keep this as a patch to the PKGBUILD file so we can more easily rebuild when there are updates?
Some gstreamer packages may depend on some of those libraries but since we don't ship those codecs, I think we're OK.

(consider doing the same thing for opencv?)

The modified PKGBUILD makes a massive difference:

Packages (1) mingw-w64-x86_64-ffmpeg-4.4-7

Total Installed Size:   17.68 MiB
Net Upgrade Size:      -34.61 MiB

With this one change alone, when comparing with the 4.2 release:

the full EXE installer has shrunk from 123MB down to 109MB
the "client" EXE installer shrinks from 71MB down to 60MB.

Also removing libx265 using --disable-libx265 would get rid of a 19MB DLL!
Unfortunately, it's also used by gstreamer plugins via libgstriff so it still gets included.
(and rebuilding gstreamer modules is probably a step too far)

Perhaps we should explicitly disable more codecs just in case they end up being installed on the build system for other reasons as the ffmpeg build will then enable them?

Not ffmpeg related, but 024f8e3 trims more unnecessary test files.

The minimal client EXE installer is now just 50MB!
Not bad at all considering that the biggest client EXE installers are from the 3.1 branch: a whopping 140MB!

To ensure that upstream packages don't update this custom ffmpeg package, I have added to /etc/pacman.conf:

IgnorePkg = mingw-w64-x86_64-ffmpeg

Which means that the ffmpeg updates will need to be done manually with a rebuild...
(fortunately, those don't happen too often)

totaam · 2021-08-30T13:54:02Z

This seems to have caused the enc_ffmpeg encoder to fail to locate any valid formats..
I guess we would need a tool like gentoo's revdep-rebuild to figure out when libraries need a rebuild.

As a result, I tried a different patch. This one ends up enabling only mpeg+mp4, which is good because other formats would be redundant.

Note: we went back to using upstream builds to avoid the breakage this causes when dependencies require a rebuild.

FWIW we no longer use ffmpeg directly: 20bb5f0
