OBS-TRTC

Demo for using OBS WHIP to publish a stream to the TRTC(Tencent Real-Time Communication) service.

Overview

OBS includes WHIP support, which allows you to do many interesting things by combining the powers of both OBS and WHIP.

WHIP is a standard protocol that lets you use HTML5 and different clients to publish and play live streams. Plus, you can use open-source tools to build your own live streaming platform.

You can also use TRTC (Tencent Real-Time Communication) cloud services with OBS WHIP support for a streaming platform. This is a great option if you don’t want to build your own platform or need a more reliable and stable platform with dedicated support.

Additionally, TRTC (Tencent Real-Time Communication) provides a free trial that includes a specific amount of streaming time, making it super easy for you to try out.

If you need help or run into any problems, don’t hesitate to contact us on Discord.

Prerequisites

Before you move forward, double-check that you’ve got these necessary items ready:

Note: Currently, OBS WHIP has been merged into the master branch but has not been released yet. You can login GitHub and download OBS 30+ from here.

Next, you need to create a TRTC application and generate a Bearer Token for WHIP.

Step 1: Create a TRTC application

Please follow the steps below to create a TRTC application:

  1. Log in to the TRTC console and click Application Management on the left sidebar.
  2. Click Create Application and enter the application name.
  3. Click Create to create the application.

001

After the application is created, you can view the SDKAppID and SDKSecretKey on the application details page.

003

Following that, you must generate a Bearer Token for WHIP, which will be utilized in OBS.

Step 2: Create a Bearer Token for WHIP

You can directly visit https://tencent-rtc.github.io/obs-trtc/bearer.html to create a WHIP Bearer Token. Ensure that use the appid with your own SDKAppID and secret with your own SDKSecretKey, then click the Generate Bearer Token button.

0031

Note: You can also access the url https://tencent-rtc.github.io/obs-trtc/bearer.html?appid=2000xxx&secret=yyyyyy to setup the parameters.

Next, use the generated WHIP Bearer Token to configure OBS.

Step 3: Configure OBS

In the OBS WHIP section, you will find the generated WHIP Server and Bearer Token for configuring OBS.

004

Please follow the steps below to configure OBS:

  1. Open OBS and click Settings.
  2. Click Stream on the left sidebar.
  3. Select WHIP for Service.
  4. Make sure to input the Server and Bearer Token accurately.
  5. Click OK to save the settings.
  6. Click Start Streaming to start streaming.

005

At this point, the stream is streaming to the TRTC service.

Step 4: Play the stream

Open the previous webpage, go to the WHEP Player section, and click Play Stream to play the stream via WHEP.

006

Another option is go to the TRTC Room section, and click Join Room to access the TRTC room and watch the stream via TRTC, or you can utilize the TRTC mobile SDK to join the room and view the stream.

007

Since both WHIP and WHEP are standard protocols, you can utilize any client that supmv ports them to play the stream.
