Autoplaying video without sound - html

I just finished reading this article on why autoplaying video is bad http://www.punkchip.com/autoplay-is-bad-for-all-users/. I knew autoplaying was a bad practice but this video gave me good, tangible reasons why its not a best practice.
My question, sites like YouTube, KickStarter and ProductHunt DO have autoplaying video, the catch is the audio is muted.
I'm working on a site for a client now, more specifically a page in which the client might request the video be autoplayed. Obviously this behavior would not be acceptable on with sound, but how about if I muted the sound by default and provided a volume button like ProductHunt?
And just replaced the video with a poster image on mobile? Thoughts?
Thanks.

If you will be using the HTML5 player native to the browser. HTML5 video does provide the ability to mute a video and autoplay it. You simply have to include the 'muted' and 'autoplay' properties in your video tags in addition to the 'controls' property so that users have the ability to play,pause, unmute etc, as an example, the code would look like this:
<html>
<body>
<video width="320" height="240" autoplay controls muted>
<source src="movie.mp4" type="video/mp4">
<source src="movie.ogg" type="video/ogg">
Your browser does not support the video tag.
</video>
<p><strong>Note:</strong> The muted attribute of the video tag is not supported in Internet Explorer 9 and earlier versions.</p>
</body>
</html>

Html5 video lacks anti-aliasing?

I'm trying to add video to a portfolio site I'm working on, but it has this choppy quality to it, like it's lacking anti-aliasing.
Or it could be something else.. Does anybody have any clues?
It looks fine when I play it in a video player.
(Open the image in full view to see artifacts better)
Here's the code for the video tag:
<video width="100%" class="videoStyle" autoplay muted loop>
<source src="video/01-02.mov" type="video/mp4">
Your browser does not support the video tag.

How can I autoplay an html video on Chrome 72, avoiding it to start or not start randomly?

I have a short video that should autoplay in Chrome. I've read plenty about this problem and tried a lot of solutions. Presently my code to play the video is
<video autoplay="true" playsinline muted >
<source src="assets/video/somevideo.webm" type="video/webm" />
</video>
This plays the video, but in an apparently random way. Sometimes the video starts, sometimes not, showing a white screen instead.
The video format is compatible with Chrome ('sometimes' it starts correctly!). The html attributes should be correct, taking into account the limitation of chrome in playing not muted videos.
What could be the problem and how can I play the video, being sure it will always be played?

HTML Video plays double when autoplay is enabled

On my wordpress site, when adding a video via the standard HTML Video tag, and then adding autoplay to it - when i then reload the page it sure autoplays but after a few seconds another instance starts the audio and then the audios are overlapping each other. How can i prevent this? This is my simple code.
<video width="400" controls autoplay>
<source src="/uploads/2018/04/ML_video-converted-with-Clipchamp.mp4" type="video/mp4">
Your browser does not support HTML5 video.

Latest IOS10 Autoplay Enable

Anyone does have the idea of how apply the html5 code for video and allow autoplay in Ios10 or latest? Cause seems like Ios10 do have the latest update and it couldn't allow Autoplay. Following are the tag that im using.
<video preload="auto" id="lady_vid">
<source src="vid/lady.mp4" type="video/mp4"></source>
</video>
I was able to enable autoplay by using the following code:
<video autoplay muted playsinline>
<source src="http://example.com/video.mp4">
</video>
You need autoplay to enable autoplay.
You need muted, because only videos without audio track or with disabled audio track can be autoplayed.
You need playsinline, because only inlined videos can be autoplayed. This will also cause your video to be displayed inside the page itself and not be opened in fullscreen video view.
I was only able to enable it after specifying full url to the video, e.g. http://example.com/video.mp4 (this is a fake url obviously). It was not working with relative url, such as
<source src="video.mp4">
or
<source src="folder/video.mp4">

Update:
After testing video on iOS10 for a while, I've realized that iOS10 fails to play a lot of videos. It's not a codec problem: if you encode two videos with exactly the same parameters, one might play and the other one won't.
What's even more intresting, is that most videos that cannot be played on iOS10 play perfectly well on iOS9 and iOS8.
So if your video isn't playing, try opening it with iOS Safari browser via direct link - maybe it doesn't work at all on iOS10.

Autoplay HTML5 Video without Audio track in IE9

I'm having trouble making an MP4 video autoplay in my HTML5 page in IE9.
From reading other stack overflow posts on the subject I know that it should autoplay, especially as I've already used qt-faststart on the video to move the file info to the headers, but all I'm getting is the fallback image when I look at the page in IE9 (XP).
I'm wondering if the fact that there is no audio track at all on the video could be causing IE9 to not want to autostart it? Wouldn't be the quirkiest thing IE had ever done...
The code for my video element is as follows:
<video autoplay loop preload width="1200" height="510" poster="/path/to/header-video-poster.png" class="hero__subsection__image">
<source src="/path/to/video.mp4" type="video/mp4">
<img src="/path/to/header-video-poster.png" alt="Fallback">
</video>
