@nainar who worked on https://github.com/ampproject/amphtml/pull/13553: is this the expected behaviour? It seems it launches the error when nothing is selected

@spacedino I tried [https://ampbyexample.com/components/amp-video/](https://ampbyexample.com/components/amp-video/) on Safari on iPhone 6 and all videos are loading. Could you provide me any other details to reproduce the problem you see?

I cannot replicate those, closing this issue for now.

I can reproduce with Safari+ iPhone 8, while Safari desktop works. @alanorozco are you aware on any problems with Safari on devices?

Video preview is visible but it's not playing.I think this is a problem with `amp-video`. Video itself works on Firefox (try [https://ampbyexample.com/video/amp-app-banner-android-app-not-installed.mp4](https://ampbyexample.com/video/amp-app-banner-android-app-not-installed.mp4)) but `amp-video` doesn't work properly. @ericlindley-g FYI

@alankent how I can reproduce this? Have you clicked on any of the buttons in the right bottom of the page?
