Command line flatpak that gives the user access to the youtube-dl tool. This is likely solely of use to people who use Linux computers with minimal read only root filesystems and run all applications inside flatpak containers, such as users of Endless OS.
(1) Install the flatpak repository for GNOME:
flatpak remote-add --from gnome https://sdk.gnome.org/gnome.flatpakrepo
(2) Install the required runtimes
flatpak install gnome org.freedesktop.Sdk
(3) Build the app from this directory:
flatpak-builder --force-clean --ccache --require-changes --repo=repo app org.youtubedl.YouTubeDl.json
(4) Add a remote to your local repo and install it:
flatpak --user remote-add --no-gpg-verify youtube-dl-repo /path/to/your/flatpak/repo
flatpak --user install youtube-dl-repo org.youtubedl.YouTubeDl
(5) Run the DevApp:
flatpak run org.youtubedl.YouTubeDl
Note that if you do further changes in the appdir (e.g. to the metadata), you'll need to re-publish it in your local repo and update before running it again:
flatpak build-export /path/to/your/flatpak/repo /path/to/flatpak/appdir
flatpak --user update org.youtubedl.YouTubeDl
Last, you can bundle it to a file with the build-bundle subcommand:
flatpak build-bundle /path/to/your/flatpak/repo org.youtubedl.YouTubeDl.flatpak org.youtubedl.YouTubeDl
