Zoom Video SDK Issue: 9:16 Aspect Ratio on Desktop Browser for Participants Joining from Mobile Browser

Hey @freelancer.nak

Sorry for the late reply.

Currently, we don’t support originalRatio:false on the iOS platform due to performance concerns.

I will further explain the reason:

  • Before Safari 16.4, we used a canvas as an intermediary to obtain video frame data. This allowed us to crop the video frames through the canvas. However, this approach had poor performance and often caused lag.
  • Starting with Safari 16.4, we switched to using VideoFrame for video data cropping directly, which improved performance. However, if cropping is still required, we would have to revert to the canvas intermediary solution.
  • After evaluation, we have decided not to support originalRatio: false natively on the iOS platform. For those who need this functionality, our upcoming version will introduce an interface for adding a customized video processor, allowing developers to implement their own cropping logic.

Thanks
Vic
