Integrate
Receive SRT USB CAM in OBS Studio.
Configure an OBS Studio Media Source as an SRT Listener, then send H.264 video and optional AAC-LC audio from SRT USB CAM in Caller mode.
Before you start
What you need
- SRT USB CAM installed on the sending Windows PC and OBS Studio installed on the receiving PC. The same PC can be used for a local check.
- An available UDP port that is allowed through the relevant Windows and network firewalls when the applications run on separate PCs.
- Matching port, latency, Stream ID, and encryption settings. The verified local example below uses UDP port 9000, 120 ms latency, and no encryption.
Signal path
Follow the stream from source to result.
- SRT USB CAM in Caller mode
- SRT MPEG-TS over UDP
- OBS Studio Media Source in Listener mode
Setup
Configure and verify one stage at a time.
- In OBS Studio, add a Media Source to the scene and clear Local File.
- Set Input to srt://0.0.0.0:9000?mode=listener and set Input Format to mpegts. Enter mpegts exactly, without a trailing space.
- Start or keep the OBS Media Source active so that its SRT Listener is ready before starting the sender.
- In SRT USB CAM, select the camera and optional audio input, or choose Test Signal and Auto audio for a repeatable first check.
- Set SRT USB CAM to Caller, enter the OBS PC address and port 9000, match the remaining SRT settings, then start transmission.
- Confirm that SRT USB CAM reports Streaming with a changing bitrate, the picture appears in the OBS scene, and the OBS audio meter moves when audio is enabled.
What to verify
Check the result before relying on the path.
- Roles: OBS Studio listens and SRT USB CAM calls; two Listeners or two Callers cannot establish this path.
- Format: the OBS Media Source Input Format is exactly mpegts. A trailing space prevents OBS from selecting the MPEG-TS demuxer.
- Video: the camera picture or moving test signal appears in the intended OBS scene without freezing.
- Audio: the Media Source meter moves and monitoring or recording uses the intended OBS audio settings.
- Network: the same UDP port is used at both ends and is reachable through Windows Firewall and any intervening network devices.
