I would to play a video from my computer on a screen with concerto.
I manage to build a template with several graphics fields and add pictures (from my computer) to several feeds, and link this feeds to my screen.
However when i want to add a video files in graphick content, an error message says "mp4 is not supported".
I try to add a video content, but i have only choice between URL video links, and i try with a dailymotion link, the video don't appear on visual preview and the screen, despite the video is an accepted item.
So i'm a little bit confused.
Is someone can explain me the method to play a video from a files to my computer?
Thank you by advanced for your help
