ffmpeg-build-script

This repo builds lightweight static binaries of ffmpeg and ffprobe with core functionality only using GitHub Actions. It builds when a tag is created, by pulling down the official source for that tag and compiling them on a Mac OS build runner. It is used in LosslessCut for Mac App Store and therefore is built with --disable-securetransport to prevent the private API usage that is forbidden by Apple in the App Store. For more info see this blog post. For HTTPS (TLS) we use OpenSSL instead.

Make changes

First make any needed changes in the build-ffmpeg.

Now build locally:

# rm -rf packages workspace
./build-ffmpeg --build

If all is well, test it and commit.

git push

Release

Wait for Github Actions and check in the output that otool -L looks something like this:

There should definitely not be any non-standard libraries added, especially no /usr/local/*.

Now download and test the artifacts.

To make a new release, tag a new version, and then push the tags, for example:

git tag -m '' -a 6.0-1

git push --follow-tags

Wait for GitHub actions to finish (again).

Once a draft has been auto created in GitHub, release it.

Update download-ffmpeg-* in package.json.
