Open Broadcaster Software
Open Broadcaster Software (OBS) is a free and open-source encoder for video recording, screencasting, and live streaming. It’s suitable for video game streaming, blogging, educational content, and more.
OBS links your device (a laptop or a PC) to different streaming platforms (Gcore Video Streaming, YouTube, Twitch, etc.). It takes a camera image, converts it into a video stream, and then sends it to the streaming platform.

Configure the stream parameters for optimal performance
We recommend configuring the stream parameters you will send to our server to ensure optimal streaming performance. You can adjust these settings in the OBS Output, Audio, and Video tabs.Output parameters
1. Open OBS Settings and go to the Output tab. Select Simple mode. 2. Set the parameters as follows:- Video Bitrate: The resolution of your stream determines the required bitrate: The higher the resolution, the higher the bitrate. To stream at 720p resolution, set the bitrate to 2000Kbps. If you’re broadcasting at 1080p, set the bitrate to 4000Kbps.
- Audio Bitrate: 128.
- Encoder: Software (x264), or any other H264 codec.
3. Click Advanced mode.
4. Set the parameters as follows:
- Rate control: CRF (the default value is 23)
- Keyframe Interval (0=auto): 2s
- CPU Usage Preset: veryfast
- Profile: baseline
Audio parameters
1. Open OBS Settings and go to the Audio tab.
2. Set the Sample Rate to 44.1 kHz (default) or 48 kHz. Select Stereo for the best sound quality.
3. Click Apply.
Video parameters
If you need to reduce the original resolution (downscale), follow the instructions in this section. If no resolution change is required, you can skip this step. 1. Open OBS Settings and go to the Video tab. 2. Set the following parameters:- Output (Scaled) Resolution: 1280×720
- Downscale Filter: Bicubic
- Common FPS Values: 30
You can see the stream’s output parameters here. If you need to increase the FPS to 60, make sure to also increase the bitrate accordingly for optimal stream quality.
