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 [1] https://aomedia.org/av1-features/ [2] https://trac.ffmpeg.org/wiki/Encode/AV1 [3] https://aomedia.org/license/patent-license/ |
