# A workflow to build and release fresh binaries.

name: Release

# Runs when a new tag is created. Creates a release for that tag, then builds

# ffmpeg and ffprobe on all OS & CPU combinations, then attaches them to the

# release.

push:

tags:

- "*"

# NOTE: Set the repository variable ENABLE_DEBUG to enable debugging via tmate on

# failure.

# NOTE: Set the repository variable ENABLE_SELF_HOSTED to enable self-hosted

# runners such as linux-arm64. This is set on the official repo, but forks

# will have to opt in after setting up their own self-hosted runners.

jobs:

# On a single Linux host, draft a release. Later, different hosts will build

# for each OS/CPU in parallel, and then attach the resulting binaries to this

# draft.
