What steps will reproduce the problem?

(2) create a javascript basic script that after a 100 millisecond timestamp and / or just after the DOM is properly loaded the video player is delete and reinjected with the same options
What is the expected result?
In keeping with the Chrome user protection that prevents you from starting a video with the sounds, it should be impossible to inject a video in autoplay and not muted.
What is the actual result?
The video has been loaded and played with the sounds without the user noticing.

for "youtube" iframe it seems to be fixed because even after waiting for dom loaded and reload a div with the same iframe, it does not self-play.

Thanks - you are not in an experimental groups. Please can you go to chrome://media-engagement/ and check if your test site is listed there? If so, please can you tell me the score and the "Is High" value for that site?

I test direct via the open file "file: /// C: /Users/Quentin/Desktop/bug.html" I add to my test server if you want to test: http://quentingosset.com/bug. html when i use your options: chrome: // media-engagement / i see my site but the time of the last 'lasplayback' is not put at the right time so i do not know if it's really a correct statistic . IsHigh: No Rating: 0.08 I just noticed that if you open: http://quentingosset.com/bug.html, the video stays on a black background (buffer not load?) And the video does not start. On the other hand, if I refresh the page, this time the video is launched as in the previously described bug (The video may have been cached so that when the refresh starts the video starts?).

When you refresh the page do you have the developer tools open?

no the chrome dev tools is not open. 1) I totally close my browser 2) I open the links http://quentingosset.com/bug.html 3) When opening the video does not work (caching ??) 4) When I'm doing F5 / CTRL + F5 (windows) the video starts. !!!! I just found that if I click on the refresh icon of the chrome browser directly, the video does not actually load however ALT + F5 or F5 makes it work !!!!

I still cannot reproduce on the following platform: Google Chrome 68.0.3440.106 (Official Build) (64-bit) (cohort: Stable Installs Only) Revision 1c32c539ce0065a41cb79da7bfcd2c71af1afe62-refs/branch-heads/3440@{#794} OS Windows The only difference was in experimental configuration for the PreloadMetadataSuspend feature. However, bypassing the experiment had no effect.
