I'm a beginner user. My goal is to stream low-latency dual cameras to pc, and then record&save the videos.
Using the Compute Module & IO Board, I have done this: https://www.raspberrypi.org/documentation/hardware/computemodule/cmio-camera.md
I tested with raspistill -cs 0 & raspistill -cs 1 , and I know both cam 0&1 works.
So now, how do I turn on both cameras simultaneously?
Reading this: How can I stream H.264 video from the Raspberry Pi camera module via a web server? It seems like Raspberry Pi Cam Web interface & U4VL are the two available streaming solutions.
And looking at the UV4L dual camera example, it seems like you will need to use 2 different formats (H264&mjpeg) to start 2 separate streams? http://www.linux-projects.org/uv4l/tutorials/dual-cameras/
I'm not sure if Raspberry Pi Cam Web interface support dual camera stream, but it seems like the UV4L is the ultimate answer?
