ideally there's a page we can scrape /cc @jhheider

[jhheider]

https://artifacts.videolan.org/x264/release-macos/ maybe. won't help us generate a URL though...

[jhheider]

Probably piggybacking on debian is the way to go: http://deb.debian.org/debian/pool/main/x/x264/

Thanks @jhheider
In the last commit, I added a versioned link. But version parsing fails due to extra text (e.g. +gitbaee400)

[jhheider]

Good point. Who writes software with no releases?

[mxcl]

k so vlc don’t tag releases. Number of questions:

1. debian are doing periodic releases off master, where do they get the version? (0.155.2917)
2. what do brew do?
3. we typically do calver for this sort of thing, should we do that here?

[jhheider]

2. what do brew do?

this:

  # Cross-check the abbreviated commit hashes from the release filenames with
  # the latest commits in the `stable` Git branch:
  # https://code.videolan.org/videolan/x264/-/commits/stable
  livecheck do
    url "https://artifacts.videolan.org/x264/release-macos-arm64/"
    regex(%r{href=.*?x264[._-](r\d+)[._-]([\da-z]+)/?["' >]}i)
    strategy :page_match do |page, regex|
      # Match the version and abbreviated commit hash in filenames
      matches = page.scan(regex)

      # Fetch the `stable` Git branch Atom feed
      stable_page_data = Homebrew::Livecheck::Strategy.page_content("https://code.videolan.org/videolan/x264/-/commits/stable?format=atom")
      next if stable_page_data[:content].blank?

      # Extract commit hashes from the feed content
      commit_hashes = stable_page_data[:content].scan(%r{/commit/([\da-z]+)}i).flatten
      next if commit_hashes.blank?

      # Only keep versions with a matching commit hash in the `stable` branch
      matches.map do |match|
        release_hash = match[1]
        commit_in_stable = commit_hashes.any? do |commit_hash|
          commit_hash.start_with?(release_hash)
        end

        match[0] if commit_in_stable
      end
    end
  end

that seems pretty awful.
