Recently moved a site from Apache to IIS that was using jwplayer with an .mp4 file as the video. Kept getting a permission or file not found error when trying to play the file.
Reason: mime type of .mp4 is not a part of the default IIS 7.5 mime types, so must be added.
Brief summary of steps to enable:
- Open IIS server manager in the administrative tools menu
- Select Mime Types
- Scroll down to be sure that .mp4 mime type is in the list
- Click add on the right side
- enter ‘.mp4′ and ‘video/mp4′ (no single quotes of course
Refresh your page and try out the video. Should now work.
