Chrome 64 Mobile Android not preload and not autoplay muted videos

We encounter issue with Chrome 64 video element which not loaded and not autoplay although we used video attributes preload="auto" and muted on HTML element.
the video start load and paused, after research, we discovered it never starts to play, like the browser blocked it from playing.
our video doesn't have sound, no sound channel at all, and still no autoplay.
Chrome 63 working great and the same device with 64 stop autoplay.
we did all the things Google Chrome wrote in the release notes, but we think there is another issue we don't know about.

We discover that you need to add preload="auto" as HTML element attribute, but you also must put on JavaScript HTML element videoElement.muted=true as normal JS attribute.
it looks like a bug in Chrome.

Make sure data-saver is disabled. If data-saver is on, it will not load video.

MP4 Video Not Playing in Chrome 56 or 57 on Android

I have a web application which plays an mp4 video at the beginning. This video is not playing in the latest version (v57) as well as in the previous version (v56) of Chrome in Android devices. The video was playing fine until Chrome v54.
It's an mp4 file. Has Google brought in any restrictions on the mp4 video files? The video plays fine in PC or Mac. The issue is only with Android devices.
Can someone throw some light?
Thanks.

I found if the Chrome Data Saver feature is turned on, videos would not appear or play.

Black screen on chrome for android html5 video

Problem:
The videos are placed in my site: http://dege.cloud/ (click on one of the pictures)
When I load the page on my desktop or on firefox mobile everything is fine.
When the same page is loaded on chrome for android the video is black without controls, the videos don't have audio, so I don't know if it plays.
Expected results:
The videos should be playable, hml5 video tag doesn't start automatically on mobile, but that's not a problem.
Analysis:
The Content-Type of the videos are correct and inspecting the console on the device don't provide errors.
I gave webm and mp4 version of the videos (ripped from http://giphy.com/ ).
The code for the video is this:
<video autoplay muted loop class="img-responsive img-centered">
<source src="img/portfolio/campominato-video.webm" type="video/webm" class="img-responsive img-centered">
<source src="img/portfolio/campominato-video.mp4" type="video/mp4" class="img-responsive img-centered">
<img src="img/portfolio/campominato-screen.png" class="img-responsive img-centered">
</video>
jsfiddle of the problem in action:
https://jsfiddle.net/Dege/1es4516p/

From what I can tell, the problem is the expectation that it would autoplay; while chrome Android 53 will autoplay muted videos, the current default version (51) won't.
In any case, if you add the controls attribute to the video element and press play, the video correctly plays, which confirms it is not an encoding issue.
(FWIW, the jsfiddle has 3 slashes in the http scheme used to load the videos; that's not the issue, but you might want to fix it nevertheless)

Android webview video play inline on 4.2

I'm building an app with a WebView thats supposed to play a mp4 video inline (not fullscreen) by html5 "video" tag.
It worked on my tablet(also 4.2), but failed on another target device.
Tested with default browser, always played in fullscreen and can't play second time.
I tried changing Webview Class to VideoEnabledWebView which says could solve most video problem,
but my webview still can't play video inline, only in fullscreen.
Then I install Chrome browser to test, Chrome could play video inline, but it's abnormal.

Did anyone manage to solve it? Help would be much appreciated!

android chrome embed video shows in full screen only

I made a static website tool that runs in all major browsers and iPad and Android(chrome). I show .mp4 video source with a simple embed tag. This was working just dandy until sometime this weekend. Come monday testing the video in android chrome, it plays audio only when not full screen, and plays correctly when full screen. I tested with the html5 video tag I use in other tools and actually same bug. I converted the video to other formats and codec, same bug. I tested tools that were completed months ago and working perfectly when sold, same bug. Seems likely that it started when chrome updated sometime after the 10/11 over the weekend. But as this project is on the home stretch and I had just debugged the last bugs I am putting it out there hoping for some feedback. I can't be the only one as it is happening with the video tag as well as the embed tag. It has to be chrome that changed my code didn't. Any insights out there?
