However, my current setup is Chrome <-> Wowza <-> iOS Safari. The video freezes in the safari webbrowser after some time. On that iOS device I can still hear the audio, but the video is frozen. On the Chrome side I can both see and hear the other side. So in Wowza, all streams are ok. If I run the same setup with Chrome <-> Wowza <-> Desktop Safari or Chrome <-> Wowza <-> Chrome (Desktop or Android) I don't see this issue. So it looks like a iOS Safari issue. It also appears to trigger this freeze bug more easily when there is a lot of movement in the video, eg when the resolution changes due to limited bandwidth or maybe other h264 parameters. I tried this with both UDP and TCP and give the same results. I also tried different css styles in the hope to have it rendered differently as described here: https://bugs.webkit.org/show_bug.cgi?id=176439 I am using h264 with profile id 42e01f, to be the same as appr.tc and Tried to run the chrome side on Windows, Ubuntu and Mac, all with the same results. 1414785 1 youennf 2018-04-16 08:44:37 -0700 Thanks Tom, We are working on it.
