How to use bitRate option for IOS Screen Recording

Hello,

I tried to screen record on iOS Simulator, and succeeded using the timeLimit option. I would like to use the bitRate option mentioned in Appium doc to reduce the size of the video, since video quality is not the goal here:

http://appium.io/docs/en/commands/device/recording-screen/start-recording-screen/

However, I could only find the method withBitRate() in AndroidStartScreenRecordingOptions and not for IOSStartScreenRecordingOptions, although it says “IOS Only” for this option in Appium doc.

Could anybody tell me if the options mentioned in the docs are all implemented? Any help would be appreciated.

Thank you in advance.
