1. Please make sure you have properly set credentials for the rtsp server. This is a username and password that will be used to protect the outgoing stream for security purposes (even in non-secure mode). Without it, the service will not stream. See here for how to set.

2. Does any other command work such as CameraStatus work?

3. Can you please provide the logs for the device-usb-camera service?

@divyashree123456 This might be related to outdated version of ffmpeg in your system. We had seen this kind of error a while back because the version was old. Make sure the version you are using is 6.0+. Older versions of Ubuntu such as Ubuntu 20.04 might not be able to get newer version via sudo apt get in which case you might need to get via adding a new apt repository or downloading binary. Also make sure to clean docker volumes before running all the Edgex services after updating the version.
