Operating Systems and Porting / Re: kernel config: page size 4k vs 64k
« on: September 16, 2020, 02:17:02 am »
Today I made some tests comparing Firefox WebRTC on 64k and 4k page size
With a Logitech webcam, I found both 64k and 4k worked
With Elgato Camlink 4k, v4l2-loopback and my gstreamer script, I found it only worked on 4k. With 64k, Firefox displayed the local monitor / self-view from the Camlink but the remote host wasn't receiving the picture. Firefox was receiving the picture from the remote host, so this was a one-way video problem.
The gstreamer script is a very simple chroma-key example, it is not OBS but then it is less than 10 lines of code.
