Hello Arvinder,
If your USB camera is using the UVC protocol (which is a standard for almost all USB based consumer webcams), you can try using
the ADUVC areaDetector driver to control it. We have ~12 such cameras in use at our beamlines and a further project is underway to use ADUVC cameras
for remote monitoring solutions using areaDetector. This way you could bypass an external IOC/ffmpegServer and pipe. The driver also supports
PTZ operations provided your camera allows for this.
Github Page link: https://github.com/areaDetector/ADUVC
Feel free to follow up with me if you are interested.
Best,
Jakub

Dear tech-talk-ers,
I'm having a look again at implementing controls for a usb camera using the v4l2 driver, and my approach is to use a python ioc to issue commands and set up and control an ffmpeg server, and hopefully pipe in the video stream into areaDetector/AD. I think this
seems reasonable, but if there are better approaches, I'd be eager to hear them
🙂
Looking back through the archive, it seems this was looked at in 2014, and potentially before then also. Has there been any progress on this topic since then?
If/when I do get this running, I'll post on here about it as it seems it'd be useful.
Wishing everyone good health and happy new year,
Arvinder Palaha
