vvd170501 / VLC-Android-vpn-dlna

This repository contains patches for VLC for Android which enable discovery of UPNP/DLNA servers over VPN.

These patches were tested on arm64 with some recent versions of VLC app (see below). They may not work with other versions or architectures.

Usage:

Manual patching

1. Clone the official repository, checkout a compatible version
2. Apply the first patch
3. Build the application (with libvlc) OR build a compatible version of libvlc and replace the libvlc.so in the original APK (e.g. using Apktool)
4. Add --miface=tun0 (real interface name may be different) in Advanced settings -> custom libVLC options
5. Restart the application

To use another interface (e.g. a wireless adapter) for DLNA discovery, remove the --miface option and restart the app

Automatic interface selection:

You may apply the second patch after step 2. With this patch applied, libupnp will use the default interface which is used to send packets to 239.255.255.250 (i.e. $(ip route get 239.255.255.250)). You should still be able to overwrite the interface for libupnp via the --miface option

Build with Docker (applies both patches)

# build the APK (unsigned release version)
./build.sh
# build only libvlc
./build.sh -l

You can use ARCH (default is arm64) and VERSION (default 3.5.0) environment variables to select a different architecture or VLC version. Use DOCKER_IMAGE_TAG environment variable to select which version of registry.videolan.org/vlc-debian-android image will be used for build.

Generated files are saved to ./out.
