[pmwiki-users] Video problems with Safari 9.0.1

I post videos on our PmWiki as simple upload links: "[[Attach:Video.mp4]]".  This has worked fine until Safari 9.0.1, which doesn’t play them. They still play in Google Chrome and Firefox. To troubleshoot, I updated to the latest PmWiki software and used the PmWiki Site Analyzer to check Cookbook and configuration and disabled all my Safari extensions. Safari still won’t play the videos. What I discovered is that the video _does_ play if I move it out of PmWiki and just link to it directly.

You can try this yourself in my WikiSandbox: <https://ix.cs.uoregon.edu/~paul/wackie/index.php?n=Main.WikiSandbox>.

Here is the wiki markup of those two links. The file pointed to in the second line is a symlink to the file in my "uploads" directory; it is the same file.

*[[Attach:Concession_LAN_800k-h.mp4]] (works with Chrome46.0.2490.86, Firefox42, Safari5.1.10)

What is PmWiki doing that keeps this from playing in Safari 9.0.1?
