Raspberry Pi 4 Camera - Does it still drop frames?

Sun Nov 10, 2019 6:04 pm

Hi everyone

A couple of years ago I was trying to fix the frame drop issues with RPi3 and default cameras. I tried C++ , but it was not completely satisfactory: ... 3&t=180929

In the end it turned out that the frame timing can be tracked correctly - but that the GPU would sometimes not pass the image to the CPU. So a solution was to track the frame #/time and either fill the video with garbage online - or fix it offline.

Does the RP4 + camera or arducam still drop frames? I am interested in streaming 1080p or 720p from 2-3 RPI4s to a desktop. I would prefer to not have to deal with this issue (i.e. another option is to purchase stand-alone cameras).

Also is the arducam any better? My recollection was that the issue was a mix of OS and RPi3 issues.

Thanks so much for the advice, ... gKD9fD_BwE
