How to use the video.php attachment template

WordPress should pick up the new attachment template automatically.

Nope. ??
When I add a movie file (e.g., movie.mp4), wordpress writes only this contruct:
<a href="path/to/movie.mp4">video</a>
and the link send me directly to the file. The image.php is not used.

When you insert it, are you remembering to select “Post URL”?

Thank you esmi for the tip! I didn’t see this option. ^^

Now wp uses video.php if I upload an mp4 video.
But if I upload an ogg video, wp doesn’t use video.php. I think this is due to the fact that wp doesn’t recognize the ogg mimetype.
Do you know in which file I can add this extension without using any plugin?
