QQ/Wechat video chat resolution?
« on: April 25, 2020, 06:12:44 PM »
Does anyone know what type of video stream happens in QQ and Wechat video chat? What are the max resolutions?

Skype and Zoom both can do 1080p streams, don't know what fps - 30, presumably.

those depend on the resolution in your phone as well as bandwidth situation. They're mostly handled on the backend if i remember correctly.

I wonder if there's an upper limit or if they just accept whatever you pump out. A Samsung Galaxy S10 for instance can do 2160p 60fps video. External webcams, like say Logitech c920, would be capable of 1080p 30fps. Built in webcams would be way lower, I guess.

Basically this is a production question. If, say, preparing a video stream to be seen over, say, QQ Video chat, how much can QQ take?

Turns out Wechat video calls are definitely NOT 16:9. On a six person video call recently my 16:9 video output was cropped into more like a vertical rectangle. I guess 4:3 aspect ratio.



Coincidentally discovered that you have to flip OBS output horizontally if you want it to not look reversed on wechat too.

Might also have discovered that doing a wonderful ppt demonstration on a wechat call is near completely wasted if no one has the ability to highlight your one window and make it fullscreen over all the other.  :(
