After deployment, it's impossible play video


I want to play a video with the HTML5 element. The video’s source is dynamic and locate in my app.

When I do that on local server, no problem. But on the deployment server, the video can’t be played. I change the file permissions with the terminal and the owner but it always doesn’t work.

The videos are uploaded with the package tomi:upload-server.
If I deploy the app with the videos, without to change permissions (read and execution for all) and the owner (“meteoruser”), I’ve no problem for the video’s reading.
If I upload a video on the server, I change permissions and the owner (the same !) but the video can’t be read…

Thanks for your help !
