ffserver supplying wrong MIME type for mp4

I have a video stream I am streaming from ffserver that works fine on the webm side (in Chrome), however the h264/mp4 side does not work, at least not in Internet Explorer.

Internet Explorer supplies an error of: 'MEDIA12899: AUDIO/VIDEO: Unknown MIME type'

Looking at what is going on in fiddler it appears that it is using a header containing:

Content-Type: application/mp4

Shouldn't that type be video/mp4 ?

In ffserver this particular stream is configured as:

<Stream 720.mp4>
Feed 720_h264.ffm
Format mp4
NoAudio
VideoCodec libx264
VideoSize 1280x720
VideoFrameRate 5
VideoBitRate 4096
VideoBufferSize 40000
AVOptionVideo flags +global_header
AVOptionVideo qmin 10
AVOptionVideo qmax 42
VideoGopSize 32
PreRoll 5
StartSendOnKey
</Stream>

Does anyone know how to force or correct the header set by ffserver to (presumably) make MSIE happy?

Sadly, this is hardcoded in movenc.c, and there's no way to change it, so you'd have to change the source code and recompile. I'd also recommend to send a patch to the project to fix it upstream.

../libavformat/movenc.c:    .mime_type         = "application/mp4",
../libavformat/movenc.c:    .mime_type         = "application/mp4",
../libavformat/movenc.c:    .mime_type         = "application/mp4",
