I am using RPi Cam Web Interface to stream raspberry pi camera over browser. But I need to integrate a Wi-Fi camera as well, which produces rtsp or http output. I want to know if the RPi Cam Web Interface has any inbuilt support for external video coming from a WiFi camera, or if there is any hack available for this?
Rpi Cam Web Interface cannot do that. UV4L can do what you want. Not only it can live stream the native or an USB camera to any browser via
WebRTC thanks to the
Rpi camera or
UVC drivers, but can also create a virtual device from an external source like IP camera thanks to the
MJPEGStream driver. You can also have both streaming at the same time as the Streaming Server can be per-device. Audio is also supported. No configuration is required.
