Have tried:CAP_GStreamer latency 2. GStreamer also verifies that it can find a device that the module supports before advertising it, so until GStreamer can support the image format from the Pi it won't consider it as valid at the moment. The key requirement for the project is to encode the camera i Shinobi defaults to using HLS which is too laggy for cctv use. We will use raspi-vid and MediaMTX to capture a video from Camera Module V3.
