You could maybe use ffmpeg, as ffmpegViewer does it, to convert video to series of jpegs.
It is can be found in the this QThread::run():

https://github.com/areaDetector/ffmpegViewer/blob/master/ffmpegWidget/ffmpegWidget.cpp#L110

I have some alpha code for taking mjepg from an IP webcam and producing jpegs inside the URLDriver, but I have not fully implement and test it yet due to the lack of time.
 

I think Axis webcams export their images on a webpage. I am looking for something to read off of a USB Webcam (that ends up showing up as /dev/videoX on Linux).

ADURL reads from webcams such as those from Axis.

Subject: areaDetector driver for webcams?

 

Hi everyone,

Has anyone developed an areaDetector driver that reads from /dev/videoX on Linux?

Thanks!
