放大器故事放大器视频“noaudio”属性未应用

Question

I have one weird behavior about amp-video ...

The scenario is like this:

I have one story with three slides, each slide has video ( amp-video ), two of them are muted (added " noaudio " attribute) and when export that story and open in the browser, I can unmute all stories (include muted ones)... If I mute all of them, the equalizer icon is hidden. It seems that if I have one unmuted and for example 10 muted videos, that behaviour is broken.

Here is the generated HTML code:

Answer 1

noaudio is only an annotation to hide the equalizer icon, it doesn't mute the video.

The Stories audio button mutes/unmutes all videos included. If you'd like a specific video to always be muted, then remove its audio track using one of many tools available .
