I don't mean to necro-post, but did anyone ever arrive at a definitive resolution to this issue?
I'm running the latest stable BI 5.4.7.11 and I found this CGadsocket error on my newly installed LPR camera. In my case it did not result in any interruption to recording, but I'm concerned about the error and would like to resolve it. I did notice the HW Decode setting was No when I checked it after reading this thread, but my default setting for all cameras is Intel+VPP, so I think that setting was reverted somehow. I reset it back to Intel+VPP, so if it happens again I will know for sure.
Any information is welcome.
