rustdesk 47b2c05e1d ws: decouple ICE policy from force_relay — full-ICE WebRTC over WebSocket
WebSocket support folds into force_relay because a ws tunnel kills
classic TCP/UDP punching — but that conflated transport necessity with
relay policy, and the WebRTC decisions keyed off the merged flag: a ws
client built no offerer at all without TURN, and only a Relay-only-ICE
one with it. ws deployments could never reach a direct WebRTC
connection, which is exactly the path they are supposed to live on.

Split the flag. LoginConfigHandler now tracks policy_relay (the
force-always-relay option, an explicit relay request — /r ids and
retry-via-relay included — and proxy) separately; force_relay stays
policy_relay || use_ws() and keeps governing the classic paths, so
non-ws behavior is unchanged everywhere:

- the offerer's existence and ICE policy follow policy_relay: under
  pure ws the offer gathers every candidate type and may go direct;
  under relay-by-policy it stays Relay-only ICE, TURN-gated, exactly
  as before;
- the RelayResponse race applies the prefer-P2P window under ws (a
  direct ICE path is worth delaying an already-ready relay for) while
  policy relay keeps first-success semantics;
- the request carries webrtc_all_ice (hbb_common 64b54ab) so the
  controlled side knows the offer is full-ICE: it answers with full ICE
  and no TURN requirement, while offers without the bit keep today's
  relay-only answer path on every version-skew combination.

Dependencies

Desktop versions use Flutter or Sciter (deprecated) for GUI. This tutorial is for Sciter only, since it is easier and more friendly to start. Check out our CI for building the Flutter version.

Please download Sciter dynamic library yourself.

Raw Steps to build

  • Prepare your Rust development env and C++ build env

  • Install vcpkg, and set VCPKG_ROOT env variable correctly

    • Windows: vcpkg install libvpx:x64-windows-static libyuv:x64-windows-static opus:x64-windows-static aom:x64-windows-static
    • Linux/macOS: vcpkg install libvpx libyuv opus aom
  • run cargo run

Install vcpkg

git clone https://github.com/microsoft/vcpkg
cd vcpkg
git checkout 2023.04.15
cd ..
vcpkg/bootstrap-vcpkg.sh
export VCPKG_ROOT=$HOME/vcpkg
vcpkg/vcpkg install libvpx libyuv opus aom

Fix libvpx (For Fedora)

cd vcpkg/buildtrees/libvpx/src
cd *
./configure
sed -i 's/CFLAGS+=-I/CFLAGS+=-fPIC -I/g' Makefile
sed -i 's/CXXFLAGS+=-I/CXXFLAGS+=-fPIC -I/g' Makefile

cp libvpx.a $HOME/vcpkg/installed/x64-linux/lib/
cd

Build

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
git clone --recurse-submodules https://github.com/rustdesk/rustdesk
cd rustdesk
mkdir -p target/debug
wget https://raw.githubusercontent.com/c-smile/sciter-sdk/master/bin.lnx/x64/libsciter-gtk.so
mv libsciter-gtk.so target/debug

How to build with Docker

Begin by cloning the repository and building the Docker container:

git clone https://github.com/rustdesk/rustdesk
cd rustdesk
git submodule update --init --recursive
docker build -t "rustdesk-builder" .

Then, each time you need to build the application, run the following command:

docker run --rm -it -v $PWD:/home/user/rustdesk -v rustdesk-git-cache:/home/user/.cargo/git -v rustdesk-registry-cache:/home/user/.cargo/registry -e PUID="$(id -u)" -e PGID="$(id -g)" rustdesk-builder

Note that the first build may take longer before dependencies are cached, subsequent builds will be faster. Additionally, if you need to specify different arguments to the build command, you may do so at the end of the command in the <OPTIONAL-ARGS> position. For instance, if you wanted to build an optimized release version, you would run the command above followed by --release. The resulting executable will be available in the target folder on your system, and can be run with:

target/debug/rustdesk

Or, if you're running a release executable:

target/release/rustdesk

Please ensure that you run these commands from the root of the RustDesk repository, or the application may not find the required resources. Also note that other cargo subcommands such as install or run are not currently supported via this method as they would install or run the program inside the container instead of the host.
