I just set up a gallery with an M4V video in it. I added class_video plugin, and the video play just fine. However, it has a default m4v thumbnail. Is there a way to change to a custom thumbnail?

Should the gallery be extracting the existing thumbnail (I have having an issue with refreshing metadata

If you place an image with the same root name as the Video then it will be used as a thumbnail. For Instance the video My.m4v would use the image My.jpeg as its video. My.jpeg would not show as an image in the album in that case.

Thanks!!

file is maybelle.m4v, and thumb, 72x98 is maybelle.jpg

Still not working.

Never mind. ID 10 T error. I was adding file to master, and not the web folder
