Streaming Issues with OWT iOS version 5.1 rc1

[rouzbeh-abadi]

Hello, I'm reaching out again with another issue relating to video streaming on the OWT iOS client.

Previously, I opened issue #724, where I described a problem that occurs when streaming video at resolutions greater than HD. The video stream appears fine on the iOS device but freezes on the receiving end.

To try and resolve this, I updated my iOS OWT client from the last stable version (5.0, released on 14th April 2021) to the pre-release version (5.1 rc1, released on 7th April 2023). However, this update introduced a new issue.

Expected Results: After updating to version 5.1 rc1, I expected the previous video freezing issue to be resolved and video streaming to function properly across all resolutions.

Actual Results: After updating to 5.1 rc1, audio streaming works as expected, but there is no video stream at all, irrespective of the resolution. This is a new issue that didn't occur on version 5.0.

Steps to reproduce:

1. Update iOS OWT client from version 5.0 to 5.1 rc1.
2. Start a video stream (tested with various resolutions).
3. Audio streams as expected, but there's no video stream.

Before diving deeper into the issue on my end, I wanted to check:

• Has version 5.1 rc1 been tested thoroughly? Are there any known issues relating to video streaming that I should be aware of?
• What version of the OWT server is compatible with the OWT iOS 5.1 version?

Any guidance or insight would be greatly appreciated.
