Just a question about HTML5 <video> tag

[NightAngel]

Hi !

I don't know if my message is in the right place, but... I'll give it a try 😜

When I switch the editor to "Source" mode to enter HTML code, if I use an HTML5 <video> tag, the system automatically adds a "src" argument (to this tag).

In fact, the system uses the src argument of the first <source> tag it finds inside the <video> tag.

Text entered :

<video>
  <source src="movie.mp4" type="video/mp4">
  <source src="movie.ogg" type="video/ogg">
</video>

Recorded text :

<video data-video-embed="" id="ips_uid_5381_4" src="movie.mp4">
  <source data-video-src="movie.mp4" src="movie.mp4" type="video/mp4">
  <source src="movie.ogg" type="video/ogg">
</video>

I could be wrong, but it seems that by doing this, the browser that doesn't support mp4 format can't switch to the ogg format source.

This is just an example, I work with H265/HEVC and AV1 codecs, but it doesn't matter.

If you have any proposals, suggestions or opinions...

Thank you very much and have a nice day !

Im a little confused as to what you are asking there. We do not modify the ogg one, no. If you are adding in source though, you can add whatever you need of course

[NightAngel]

When no src attribute is specified in the <video> tag, the browser is free to choose the source with which it is compatible.

But if I don't put a src attribute in the <video> tag then IPB (I assume) modifies my <video> tag to add the src attribute of the first <source> tag contained in the <video> tag.

In this way, the browser ignores the different sources offered and reads the src attribute of the <video> tag in all cases.

The idea is that a browser that supports the H265 codec can play .mp4 video, while a browser that supports the AV1 codec can play .webm video.

I have flagged this for a developer to take a look at and advise further for you

That's expected, due to lazy-loading.

The Javascript asks the browser which formats it can play and adds the appropriate one to the src attribute. However, I do see there's an issue there were the second source element isn't being parsed properly to have the data-video-source attribute. I was able to reproduce that and commit a fix for it.

Thank you for your prompt and efficient handling of my request. 👍🏻
