Hello Sonia,

You are sending huge enough video
ScreenV1 codec compression ratio is not very good
So the bandwidth will depends on what is being shared (i.e. if more or less
static picture is being transferred the bandwidth will be mach smaller)

h263/h264 will create better compressed video
have you tried to share 1440x816 camera stream? what will be the numbers?

ps it is better to use user@ list since this question is not related to OM
development
