WebM videos are served with a wrong MIME type. It's always the following: Content-Type: audio/webm For videos this should be: Content-Type: video/webm See http://www.webmproject.org/docs/container/ for more information. It seems to be no problem inside the html video tag, but there are programs which don't show the video if the content-type is "audio/webm" and the file is called directly.
Looks like Gerrit change #41038
Umherirrender: Good catch, thanks! Patch merged => closing bug report as FIXED.
