x265-4.0 (wait for downstream adaption)

[Bruce Dubbs]

New major version.

Note that this will cause gst-plugins-bad and ffmpeg FTBFS.

This might get it for ffmpeg:

imlib2 doesn't use x265 anymore

We are missing a dependency on x265 in VLC though, and it does not build with x265-4.0. Going to look for a patch next.

[Douglas R. Reno]

No patch is available, and given that gst-plugins-bad is also still broken, let's wait on this. I was able to come up with a chunk of code for VLC that allowed it to build, however crashed when trying to encode an x265 file. Here's what upstream has to say about this: ​https://mailman.videolan.org/pipermail/x265-devel/2024-September/013945.html, and the API docs are at ​https://x265.readthedocs.io/en/master/api.html#encoder

Note that you will see an update commit and then a revert commit. I had updated it in my sandbox expecting to be able to use it, but this is unusable until ffmpeg/vlc/gst-plugins-bad are updated to use it. ffmpeg's patch does seem to build but I have not tested it.
