Hi,

I have a couples of AV1 videos that I would like to display on a html page.

I've tried

<video controls preload="none">
    <source src="FooBar.mp4">
</video>

but it trow back

I've tried first with MKV container as it's listed on the wikipedia page.

but this is not listed on the mozilla page https://developer.mozilla.org/en-US/docs/Web/Media/Formats/Video_codecs ๐Ÿค”

Confusing.. as I found also this in the firefox release note:

Firefox 97 and later versions support AV1 video in the MKV container.

So WTF !?

I've tried also

<video controls preload="none">
    <source src="FooBar.mp4" type="video/webm; codecs='av01.0.08M.08'">
</video>

but that change nothing...

Any ideas ?

Thanks.

Funny when I open .mp4 container version of it, by file path (url bar) like file:///X:/path/FooBar.mp4 it works, so Firefox can Open it.... (now still to make it work inside an html page ๐Ÿ˜‘ )

for .mkv it trigger a file download...

Your html looks wrong to me in your second example.

The type should be closed with " not continued with ; Codecs should also use" "

I don't think the Codecs bit is needed though. Having the Type correct should be enough.

<video controls preload="none"> <source src="FooBar.mp4" type="video/webm"> </video>

Edit: Also presumably your files are definitely AV1? Double check that. I think you can also drag and drop video into Firefox to see if they will play.

Edit2: Also on searching I've seen someone say you may need to use the video tag itself for mkv:

<video controls preload="none" src="FooBar.mkv"> </video>

It's one of the solutions lower down on this stack post, but you'd need to test that. https://stackoverflow.com/questions/21192713/how-to-playback-mkv-video-in-web-browser

As a side, it's very frustrating to see how many people wrote code on that page that just works on Chrome. So much for Web standards!
