I was struggling with this same issue. I pretty much copied the code from http://camendesign.com/code/video_for_everybody.
<!-- first try HTML5 playback: if serving as XML, expand `controls` to `controls="controls"` and autoplay likewise -->
<!-- warning: playback does not work on iOS3 if you include the poster attribute! fixed in iOS4.0 -->
<video width="640" height="360" controls>
<!-- MP4 must be first for iPad! -->
<source src="__VIDEO__.MP4" type="video/mp4" /><!-- Safari / iOS video -->
<source src="__VIDEO__.OGV" type="video/ogg" /><!-- Firefox / Opera / Chrome10 -->
<!-- fallback to Flash: -->
<object width="640" height="360" type="application/x-shockwave-flash" data="__FLASH__.SWF">
<!-- Firefox uses the `data` attribute above, IE/Safari uses the param below -->
<param name="movie" value="__FLASH__.SWF" />
<param name="flashvars" value="controlbar=over&image=__POSTER__.JPG&file=__VIDEO__.MP4" />
<!-- fallback image. note the title field below, put the title of the video there -->
<img src="__VIDEO__.JPG" width="640" height="360" alt="__TITLE__"
title="No video playback capabilities, please download the video below" />
</object>
</video>
<!-- you *must* offer a download link as they may be able to play the file locally. customise this bit all you want -->
<p> <strong>Download Video:</strong>
Closed Format: <a href="__VIDEO__.MP4">"MP4"</a>
Open Format: <a href="__VIDEO__.OGV">"Ogg"</a>
</p>
Then made sure to create .htaccess file with the following:
AddType video/ogg .ogv
AddType video/mp4 .mp4
AddType video/webm .webm
Also, I'm using an older version of django (1.6.5) for my project and I have my videos stored at my MEDIA_ROOT and have the MEDIA_URL also set in the settings.py so that the source of video looks like:
{{ MEDIA_URL }}/media/videos/video.m4v
