This is an experimental media MOQ relay (AKA: CDN node) based on MOQT. It can be used in conjunction with following live encoder and player moq-encoder-player. Both repos allows us create a live streaming platform where we can control latency and quality (and others), so we can test scenarios from ultra low latency live (video call) to high quality (and high scale) live.

In the following figure you can see an overview of the relay architecture

TODO Fig2: Relay architecture overview

Installation

  • Just execute (probably you will need sudo unless you run it like root):
./build.sh

Test preconditions

  • Generate self signed certificate for the server applications
cd scripts
./create-server-certs.sh

Test with date server

  • Execute date server (from project root dir)
./_build/bin/moqdateserver -port 4433 -cert ./certs/certificate.pem -key ./certs/certificate.key --logging DBG
  • Execute text client
./_build/bin/moqtextclient --connect_url "https://localhost:4433/moq-date" --track_namespace "moq-date" --track_name "/date"
  • You should see an output like:

Test with media client

  • You can use moq-encoder-player as encoder (publisher), and also as player (consumer)

  • You need to install that website (moq-encoder-player) in a https server (apache2 recommended)

    • It will requiere to enable cross origin isolation (see link) on the player side

  • To start the relay you can do (from project root dir)

./_build/bin/moqrelayserver -port 4433 -cert ./certs/certificate.pem -key ./certs/certificate.key -endpoint "/moq" --logging DBG

Local test with media client (server running in localhost)

  • Execute (from project root dir)
./_build/bin/moqrelayserver -port 4433 -cert [moq-encoder-player]/certs/certificate.pem -key [moq-encoder-player]/certs/certificate.key -endpoint "/moq" --logging DBG

Note: [moq-encoder-player] indicate the root directory of that project. So you need to use those certs to enable connections from Chrome to localhost

  • Start client (MACOS) Run MOQ encoder / player locally
