Self video is not visible while doing meet phone to phone

I had build a website in which we are using jitsi iframe. If i connect two participate from phone then one participate is not able to check his own video and jitsi saying
Video for has been turned off to save bandwidth jitsi

That message suggests you don’t have sufficient bandwidth to display all video streams.

@Freddie so we need to increase bandwidth of our server which is ec2 instance?

No, that message is referring to the client’s bandwidth. So you need to increase the bandwidth of the phone that shows the message.

Can we do something for those customers who have less bandwidth or we can check what is the bandwidth of the customer

You can try switching codecs to VP9, but some phones don’t support it. Video quality constraints would have been another option, but since you’re using mobile devices, that’d require hardcoding the constraints.
