Chrome app file system in kiosk mode

Question

i have an app (signage player) that loads video and placed it in folder which user pointed on the beginning (named 'media').

Then i define source attr of video element as "media/name_of_file.mp4"

In plain mode is works well - local video plays. But i and don't know why. In Kiosk mode app can't find a files at all.

Do you have any ideas about it?

What features has or hasn't file system in kiosk mode - it's really hard to debug it there.

Many thanks for any information about file system in kiosk mode.

According to this answer, app in kiosk mode hasn't any access to file system.(but from my experience it isn't quite true, i can wright files and folders, read them via file api) Main problem that i can't reach them from dom src property.

But anyway google demand additional license for this option, so any kludges can be blocked in further versions of chrome os...

Create a shortcut to your Chrome executable, right click it, select "Properties" and then make sure the target field looks like this (for example):

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --kiosk "file:///C:/Users/JohnDoe/Desktop/MyHTMLFile.HTML"

The executable must be in double quotes, as well as the file path.

You may need to embed your MP4 inside an HTML5 element on a local HTML file for this to work.
