Webex Meetings

Set Bandwidth

To optimize your iOS app's performance you can set bandwidth constraints using the iOS Meetings SDK.

To specify the maximum bandwidth used by video, audio and screen sharing, configure the following instance variables:

phone.audioMaxBandwidth = 64000 // 64kbps
phone.videoMaxBandwidth = 2000000 // 2Mbps for 1280x720 resolution

The bandwidth unit of measure is kilobytes per second (kbps).

The SDK uses the TIAS (Transport Independent Application Specific) maximum bandwidth modifier in the SDP to implement this functionality. For more details, please see RFC3890.
