This size can be configurable? In which part of the code it is available? Could be the number of frames dynamic according to the bandwidth of each network?
If your app is running on LAN, then bandwidth shouldn’t be an issue.
I use licode with a wifi network
It depends on your resolution, and framerate.
By default, licode comes with a maximum of 20 fps and a 640x480 resolution.
Also, in licode_config.js the bandwidth is capped at 300kbit/s.
So, you need 300kbit upload for every stream you publish, and 300kbit in download for every stream you receive. This is a very low requirement for a one to one call
