Re: detecting caption files?

I know that the axe method is to look for a <video> element and see if it has child <track> elements with a "kind" attribute of "captions". Therefore, I'm surprised it didn't detect an issue. I did a scan just now on a YouTube video with no caption and it called out "<video> elements must have captions" appropriately. Could it be the video wasn't HTML5 <video>? Or could it be that there actually was a <track kind="captions"> present but no captions were coming through on the video?

That's curious!

Subject: [WebAIM] detecting caption files?

Hello everyone :)
Does anyone know of a tool that is able to detect whether or not a caption file exists on videos?
I know that aXe will flag that it can't find a caption file, but when I tried it on YouTube, on a video I know has no caption file, it didn't flag anything.

Thanks!
