Darwin ARM64: Unsupported architecture

[henryruhs]

Error: AssertionError [ERR_ASSERTION]: Unsupported architecture (only x64 is supported)

using latest MacOS on GitHub Action:

Current runner version: '2.316.0'
Operating System
  macOS
  14.4.1
  23E224
Runner Image
  Image: macos-14-arm64
  Version: 20240422.3

worked before the update of their images:

Current runner version: '2.315.0'
Operating System
  macOS
  12.7.4
  21H1123
Runner Image
  Image: macos-12
  Version: 20240412.2

I suggest a daily cron for your repo to check for future image updates.

temporary fix: use macos-12 or macos-13 ... using ffmpeg: 6.1.1 does not resolve the issue

ARM is not supported on macos

[federicocarboni]

Just to clarify what is going on, this action just downloads builds from evermeet.cx and since it doesn't support ARM we can't either.

This is not fixable without finding some source that provides ARM builds.

[henryruhs]

Homebrew is not an option?

brew install ffmpeg

Just dropping these links here, which are related to the change in default arch for mac-os runner:

@federicocarboni is this helpful http://www.osxexperts.net/ ? Seems to have ffmpeg builds on ARM

I am also encountering a similar issue: macos-latest is now using M1.

Workaround

steps:
  - name: ${{ runner.os }} on ${{ runner.arch }}
    run: echo "${{ runner.os }} on ${{ runner.arch }}"
  - uses: actions/checkout@v4
  - if: runner.os != 'macOS' || runner.arch != 'ARM64'
    uses: FedericoCarboni/setup-ffmpeg@v3
  - if: runner.os == 'macOS' && runner.arch == 'ARM64'
    run: brew install ffmpeg
  - run: ffmpeg -i input.avi output.mkv

---

Or...

steps:
  - uses: actions/checkout@v4
  - if: runner.os == 'Linux'
    run: |
      sudo apt-get update -q -q
      sudo apt-get install --yes ffmpeg
  - if: runner.os == 'macOS'
    run: brew install ffmpeg
  - if: runner.os == 'Windows'
    run: choco install ffmpeg
  - run: ffmpeg -i input.avi output.mkv

---

Or...

  - uses: AnimMouse/setup-ffmpeg@v1

[henryruhs]

Moving over to AnimMouse/setup-ffmpeg@v1 resolved the issue.

@cclauss I think you meant runner.os != 'macOS' || runner.arch != 'ARM64', right?

[cclauss]

Actually I did not. GHA macOS on Intel is history. https://github.com/actions/runner-images/issues/10721

[mifi]

yes, but will runner.os ever be ARM64?

Oh... Now I see. Changing above. Thanks.
