Steps to reproduce

Summary

IE11 on Win7 with build 11.0.9600.18537 does not play mp4 files without moov atom, which end up making native streaming of mp4 non functional.
IE11 reports “Invalid Source” on these videos. All other browers tested OK.

See attached videos, one with moov and one without.

Steps to reproduce:

Create a html file with video tags for each video attached and open it in IE11:

    <!DOCTYPE html>
    <html>
    <body>

    <video width="320" height="240" autoplay controls>
            <source src="test_with_moov.mp4" type="video/mp4">
    </video>

    <video width="320" height="240" autoplay controls>
            <source src="test_empty_moov.mp4" type="video/mp4">
    </video>

    </body>
    </html>

Browsers tested on the same machine (Win7)

NOT WORKING means test_with_moov.mp4 are playing in the software, while test_empty_moov.mp4 is not playing.

WORKING means both test_with_moov.mp4 and test_empty_moov.mp4 are playing in the software.
