Subject: AreaDetector stream encoding

Hello tech talk,

 

We are having issues with network saturation when too many clients are viewing too many simultaneous acquisitions on our 7 GigE cameras. We are currently serving the images via MJPG using AreaDetector’s ffmpeg stream. I recognize H.264/265 is probably not possible due to licensing, but I think it could be possible to instead encode our video using AV1 [1][2] if we use relatively low framerates.

 

1.       Has anyone started or tried adapting this to areaDetector?

2.       AOM libraries are available under a combination of BSD 2-Clause and their own copyleft license [3]. Are these compatible with the rest of AreaDetector?

3.       Would anyone else be interested if we were to try and add this functionality?

 

Cheers,

Evan
