Another attempt at autoplaying/looping MP4

on Apr 11, 2019 ยท

ssdifnskdjfnsdjk commented on my original MP4 post that he got an MP4 working just like an animated GIF, so I'll try again.

I also followed his tutorial for making images & videos optional, so just being a peer for this zite won't involve automatically downloading every single image and video.

Here goes attempt #2.

The code that ssd used:
<video autoplay="" loop="" muted="" src="video/file-name1.mp4" type="video/mp4">This browser does not stream this video</video>

So I'll adjust that for my file name and location.
<video autoplay="" loop="" muted="" src="data/img/Monty.Python.Every.Sperm.Is.Sacred--MP4.mp4" type="video/mp4">This browser does not stream this video</video>

And now the video...

Well, for me, in both Firefox (Quantum) and Vivaldi, the video does not autoplay. In both I have to right click on the image and select "Play". I expected that in Vivaldi because I have an extension to prevent autoplaying videos. But I have no such extension in Firefox.

Now I wonder if ages ago, when I was being particularly annoyed by autoplaying videos, maybe I went into Firefox's about:config and set autoplay to "false".

Looking there I see this:


I'll try changing that and reloading.

Nope, that did not make a difference. The video is just a still image until I right-click and choose play.

Well, almost all of those work! Even if a couple (clapper board, and especially television) are not great against a dark background.

Here's a screenshot, because when it comes to emojis, what one is shown in one browser/program/operating system won't look the same on another.

post_8_sandbox.emojis.png (594x694)

In the text file, many of them appear as emojis but not all (e.g. film frames, camera with flash, studio microphone, pirate flag {partially}). And the same things happens (to the same emojis) when I copy & paste here on ZeroBlog. (Just realized, they seem to be the sames ones that don't show right on the webpage in my browser either.)

Unfortunately the emojis that fail are among the ones I'd probably most like to use to indicate media type I'm sharing on my "media share" blog.

Let's see when I try copying & pasting those straight from the webpage into this post:

  • Film frames, copied from Vivaldi where it doesn't show: ๐ŸŽž

  • Film frames, copied from Firefox where it does show: ๐ŸŽž

Same result for me: just an empty square both times. EDIT: when viewed in Vivaldi, they're both blank squares. But when viewed in Firefox, I see the film frames both times. And at the top of the page too.

In fact the other problematic ones (camera with flash, studio microphone, pirate flag) also work in Firefox.

Inserting a WebM into a ZeroBlog post

on Mar 20, 2019

Just like I did with MP4 in the previous post, I'll try manually copying the WebM into this blog's data/img folder and then switch into Markdown edit mode (clicking </> button at top right) to put in HTML code.

I use almost the same code, but changing the file name and type, to video/webm.

<video width="500" height="286" autoplay loop>  <source src="Monty.Python.Every.Sperm.Is.Sacred--WEBM.webm" type="video/webm" />  Your browser does not support the video tag.</video>

Failure!!! I do not see the video at all, at least in the browser I'm using now (Vivaldi, based on Chromium). There is a big empty space where the video should be.

Going back into the markdown editor, I notice the first line of the HTML has had something added to it. It's gone from this:

<video width="500" height="286" autoplay loop>

to this:

<video width="500" height="286" loop="" flashstopped="true" id="dummyid39" preload="metadata">

Why, I do not know. I'll try saving, sign and publishing the post, then viewing in other browsers to see what happens.

  • Firefox: same big empty space.
  • Chrome: same big empty space.

Below I'll try editing in other browsers, to see if I can take out and keep out that unwanted code insertion. Trying in Chrome now...

Again, failure! Again, a big empty space. Again, the HTML code has been changed against my will. But this time it's been changed in a different way. Now the first two lines are:

<video width="500" height="286" autoplay="" loop="">โ€‹โ€‹โ€‹โ€‹โ€‹โ€‹โ€‹<source data-cke-saved-src="Monty.Python.Every.Sperm.Is.Sacred--WEBM.webm" src="Monty.Python.Every.Sperm.Is.Sacred--WEBM.webm" type="video/webm">

As wells as the changes to the first line, in the second, just plain src has become data-cke-saved-src. I don't know why, and I don't know what to do about this.

So at this stage, I cannot get a WebM to display in a ZeroBlog post at all, let alone playing and looping automatically like an animated GIF.

Inserting an MP4 into a ZeroBlog post

on Mar 20, 2019 ยท 3 min read ยท

I'm looking for an alternative to animated GIFs, so I need the MP4 to behave like an animated GIF does:

  • display automatically (the image is visible to the blog visitor without them having to do anything)
  • play automatically (the blog visitor doesn't have to click on the video or press "Play", etc.)
  • loop automatically (the blog visitor doesn't have to right-click and select "Loop", etc.)
  • the whole image/animation is visible without any controls overlaid on it (e.g. no control bar obscuring the bottom part of the image)

The WYSIWYG editor does not have an "Insert video" button, so this will have to be 100% manual.

And Markdown code does not have an "Insert video" tag (the way it has ![img name](img URL) for images), so I will have to find and use appropriate HTML code.

I've inserted a (long-form) video on my blog cloned from My ZeroBlog (see this post hereโ€‹โ€‹โ€‹โ€‹โ€‹โ€‹โ€‹). Let's see if I can get the video working and displaying with all the other requirements (auto play, auto loop, no control bar) here on a regular ZeroBlog.

Inserting an animated WebP into a ZeroBlog post

on Mar 20, 2019

First, we'll see what happens when I use the "Insert image" button in the WYSIWYG editor.

Monty.Python.Every.Sperm.Is.Sacred--AnimatedWEBP.webp (500x286)

Yet again, it's a still image. But this time it's a still WebP, not a JPG.


Now let's try it manually, copying the animated WebP to the right folder and inserting it through markdown.

![Monty.Python.Every.Sperm.Is.Sacred--AnimatedWEBP.webp (500x286)](data/img/Monty.Python.Every.Sperm.Is.Sacred--AnimatedWEBP.webp)

Monty.Python.Every.Sperm.Is.Sacred--AnimatedWEBP.webp (500x286)

Success!!! I see an animated WebP, automatically displaying, playing and looping.

Inserting an Animated PNG into a ZeroBlog

on Mar 20, 2019

First, I'll use the WYSIWYG editor's "Insert image" button.

Monty.Python.Every.Sperm.Is.Sacred--Animated.PNG.jpg (500x286)

Again, the animated format is converted to a still JPG.

Now I'll try placing the animated PNG manually in the folder and then using the markdown edit mode to show it.

![Monty.Python.Every.Sperm.Is.Sacred--Animated.PNG.png (500x286)](data/img/Monty.Python.Every.Sperm.Is.Sacred--Animated.PNG.png)

Monty.Python.Every.Sperm.Is.Sacred--Animated.PNG.png (500x286)

Success!!! I now see an animated PNG, automatically displaying, playing and looping.

Manually inserting a GIF into a ZeroBlog post

on Mar 20, 2019 ยท 1 min read

Now I will try:

  1. Using the WYSIWYG editor to insert a GIF.
  2. Manually placing the GIF in the data\img folder

  3. Manually copying and adjusting the post's code to show the GIF.

Testing alternatives to GIFs on a ZeroBlog

on Mar 20, 2019

First, here are links to the files stored on ZeroUp Unlimited:

Now let me try to post the original GIF here, using the WYSIWYG editor to insert it. I know it will convert it to a still JPG, but at least then I can confirm where the image will be stored.

Monty.Python.Every.Sperm.Is.Sacred--OriginalGIF.jpg (500x286)

After posting, I see:

  • a still JPG
  • I find the image is located in the blog's sub-sub data\imgfolder:


  • And the file name has been prefixed by the blog post number:

PS: Hmmm, the folder location I enclosed in code backticks, markdown-style. When it came to the file name, I remembered to use the WYSIWYG editor's "Code" button. But the results look different.
