iOS Safari – Playback speed of muted videos too fast after 2nd loop

[mlinzner]

Expected Behavior

Muted videos (looping automatically or manual) should have stable playback speed even with repeated playbacks.

Actual Behavior

On iOS Safari 14.4 and 14.5 beta, muted videos have a strangely fast playback speed after 2nd video loop.

Steps to Reproduce

• Include vimeo video with any configuration causing it to be muted. E.g. muted=1, background=1, …
• Start video and repeat playback 3 times (or wait for the autoloop to reach 3rd loop)

@mlinzner did you manage to resolve this? we are getting the same issue now on 14.7

@acndr Unfortunately not. We ended up using the default HTML5 video player. In our case the loops do not have visible controls so no one really notices. The only downside is that Vimeo Pro is required for that, else we would be fine with Vimeo Plus.
