924555 - Does Firefox for Windows support "video/quicktime" in addition to "video/mp4"?

Status: RESOLVED WONTFIX

(Core :: Audio/Video, defect)

Description

[Šime Vidas]

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0 (Beta/Release)
Build ID: 20130910160258

Steps to reproduce:

Now that Firefox for Windows supports "video/mp4" files in <video> elements, does this also include "video/quicktime" files? 

1. Page with "video/mp4" file in <video>: http://www.webpayload.com/video-episodes/speed-part-1
2. Page with "video/quicktime" file in <video>: http://www.webpayload.com/video-episodes/forms-part-2-increasing-conversions-with-good-use-of-forms


Actual results:

Firefox is able to play the video on the 1. page, but not the video on the 2. page.


Expected results:

Firefox should be able to play both variants of MP4 files, "video/mp4" and "video/quicktime".

Or?

Both these videos are H.264 videos, so as far as I understand, both should be supported in systems that have these codecs built-in.

The second URL I posted above now contains a "video/mp4". (That website, Web Payload, converted their videos to "video/mp4", after my report.)

Here is an alternative URL that contains a "video/quicktime": http://freecourses.tutsplus.com/30-days-to-learn-html-and-css/images.html

Reproduced on latest Aurora (20131014004003): "Error loading media: File could not be played" is displayed on the video.

Browser's console:
HTTP "Content-Type" of "video/quicktime" is not supported. Load of media resource http://d2qpdl5ntmaj0h.cloudfront.net/tutspremium/courses_$folder$/30DaysHTMLCSS/nostring/Day-10-Images.mov failed. images.html
"Error playing media: " [object MediaError]

No, we do not and AFAIK will not support video/quicktime in the HTML <video> element.

Would you care to elaborate why? The codec is (AFAICT) the same as the supported "video/mp4".
Why should the MIME type difference matter?

video/mp4 and video/quicktime are different container formats. Although they can have streams inside them encoded using the same codecs, the container itself is a different format. I'm not familiar with how compatible they are (as MP4 was based on MOV at some point IIRC) but that's the reason why the difference matters. We don't use a MOV container parser.
