Hello,
We have a number of mp4's uploaded into DMX, and Chrome, IE, FireFox are all able to play the uploaded videos perfectly (using JWPlayer).
We have been unable to get the same videos to play on iOS devices or in Safari. After some investigation, it seems that the files coming from DMX have different headers, and are giving different HTTP codes than static mp4's on the same server.

The DMX file returns a status code 200, while the MP4 returns a 206.
Here are the response headers:

DMX:
Cache-Control: no-cache
Content-Disposition: attachment; filename=bunny.mp4

How can I get these videos to play in these other environments?
Thanks,
Damian

Hi Damian,

The only way I could see to do this is to create a custom download handler for this file type. It can be done without forking the module. You need to have the partial source version, copy the download.aspx page and give it some meaningful name and adjust the code for it. Then, finally, to adjust the record in DMX_Extensions for the mp4 file type to point to this new aspx.
