# LGPL-only libVLC for NovArc's Android app (review L1, the owner's decision 2026-10-12): VideoLAN's own
# vlc-android build at tag libvlc-3.7.6, with the contribs built from source with `--license a`
# (LGPLv2 + ad-clauses) instead of the prebuilt GPL-mode contribs CI uses (`-t`). Same images as
# VideoLAN's CI for each ABI. Throwaway containers, capped so Jellyfin keeps running.
# Output: ~/builds/libvlc-lgpl/m2 (a local Maven repo with org.videolan.android:libvlc-all:3.7.6),
# contrib source tarballs kept for the source offer. Log: ~/builds/libvlc-lgpl/build.log
