OBS Setup Settings

Note: Please ignore any settings not shown in the image below. If OBS prompts for system permissions, ensure you grant/allow them to proceed.

Before you start streaming, click Settings in the bottom-right corner of the OBS interface.

Go to Output and set Output Mode to Advanced. Under the Streaming tab, select x264 as the Video Encoder. Then, configure the Encoder Settings as shown in the image below.

How to Create and Manage Live Stream Sources

Please note: the content displayed on the canvas is exactly what will be shown in the livestream.

3.1 Add livestream content.

Locate the "Sources "panel at the bottom of the OBS interface.

Click the [+] button at the bottom left of the panel to display a list of different 'Source' types, then choose one based on your requirements.

Select the content you want to add to your live stream, such as:
- Mac: “macOS Screen Capture” — Display Capture / Window Capture / Application Capture.
- Windows: “Display Capture” : share the entire computer screen; “Window Capture” : share only a specific window, such as a game or a browser.
- “Image”: add an image file.
- “Media Source”: add a local video.
- “Text”: add text.
- “Video Capture Device”: connect the streamer’s camera so viewers can see the streamer.

Appendix: Example of Source Configuration:

3.2 Configuration and Adjustment

After selecting the source type, a configuration window will appear. Follow the prompts to choose the specific content you wish to capture. For instance, if you select [Window Capture], you will need to choose the exact window you want to share.
After adding the content, it will appear on the OBS preview canvas. You can freely drag, resize, and adjust its position and size.

3.3 Privacy and Security Considerations

When selecting a Source, exercise caution, especially if you are sharing your entire computer screen.
We strongly recommend using Window Capture. This setting ensures that viewers can only see the specific window you have chosen, effectively preventing the accidental exposure of private information, such as chat logs, personal files, or sensitive websites.

Configure Streaming Settings

Please follow the correct order: first start the live stream on Billion, obtain the stream key and configure it in OBS, then start the live stream in OBS.

On your streaming platform's [Live Center] (or equivalent live streaming dashboard), fill in your stream details (title, Category, etc.). Select [OBS] as your streaming software option, and then click [Go Live].

Once the stream is started (or configured), scroll down the page and copy the Server and Stream Key.Note: Please copy the stream key again before each livestream.

Click [Settings] in the bottom-right corner of OBS, select the [Stream] tab, and choose [Custom] under [Service] on the right.

Paste the copied server address into the Server field and the stream key into the Stream Key field within OBS. Click [OK] at the bottom right to save the changes.

After clicking [Start Streaming] in the bottom-right corner of OBS, the livestream will officially start on Billion.

Note: The Billion livestream preview is shown below.

OBS Streaming Recommendations

To ensure a smooth live stream and the best possible viewing experience, we recommend completing the following preparations before going live. Familiarity with your live streaming software is key to improving overall stream quality.

Please do not change the streaming server during the live stream.

Do not change the streaming node or server region during the live stream, as this may cause instability.

Video and Audio Testing

Video Setup: Within OBS or your preferred streaming software, confirm that your video sources (such as a webcam, game capture, or desktop display) are correctly added and displaying as expected. We recommend previewing your video either in OBS or in your streamer dashboard to ensure your viewers have the best possible experience.
Audio Setup: Ensure your microphone settings provide clear, echo-free sound. Use headphones to monitor your audio—this is the quickest way to detect and resolve issues like background noise, echo, or low volume before you go live.

Content Elements

Visual Enhancements: Using the built-in features of your streaming software, you can easily add personalized elements such as desktop pets, images, and text overlays to make your live stream more engaging.

live stream Testing

Internal Testing: If you are using streaming software for the first time, test your video clarity and audio settings within OBS in advance. This helps you thoroughly check all devices and configurations to ensure the video and sound output meet expectations. By doing so, you can identify and resolve technical issues ahead of time and avoid last-minute problems during the live broadcast.

Make sure the resolution in the settings matches your computer screen resolution, and that the base resolution and output resolution are set to the same value.

OBS Issue Responses

1. OBS Live Audio Echo Issue

On the audio mixer, you can adjust the corresponding speaker icons. Click the speaker icon to mute a channel and select only the channel the user wants to stream.

If you open your own live room in a browser to check the stream, the browser audio will be captured again by OBS Desktop Audio, creating an infinite feedback loop and causing echo. Please turn off the live room sound in the browser or mute the playback page directly. If you stream a local recording and the audio sounds normal in the local file but echoes in the live room, then it is 100% caused by leaving the live room page unmuted.

2. Live Stream Resolution

The blurry image may be caused by a frame rate that is too low or an improperly configured bitrate. It is recommended to:

Set the live stream frame rate to 30 (in OBS: [Settings]— [Output] — [Streaming]).

Set the bitrate to 2300 Kbps.

If your bandwidth is sufficient, set the frame rate to 60 and the bitrate to 4000–6000 Kbps.
