Can i play a video directly from URL in mobile device ?

Acording to the Unity docs - this is currently unsupported.

http://docs.unity3d.com/Documentation/Manual/iphone-unsupported.html http://docs.unity3d.com/Documentation/Manual/android-unsupported.html

However...

This requires Unity Pro and iPhone Pro! Also, this code should work - I haven't tested it yet (I will do it soon).

There are 3 steps to do what you want.

1. Download the file from the server

2. Move the file to the proper directory

3. Play the file

Assuming you know how to download a file using the WWW class, the Unity Docs tell us that the StreamingAssets folder path is different on every device - for iPhone, we can use:

 moviePath = Application.dataPath + "/Raw" + "/behappy-vide.mp4;

After saving the movie to the correct folder, all we have to do is call:

 Handheld.PlayFullScreenMovie (moviePath, Color.black, FullScreenMovieControlMode.CancelOnInput);

This will fade in to our video and play it.

Let me know if you need any help or if it doesn't work properly.

I tried to save a video to said path, but it didn't work : When I try to write the file, I get an exception

UnauthorizedAccessException: Access to the path "/var/mobile/Applications/6FDD4123-B161-473B-A58F-F1C3FEC6589A/bluejacket.app/Data/Raw/TestVideo.mov" is denied.

I can't say I'm surprised. Writing a file to the device, just like this, without providing a written permission from the Apple CEO, provisioning profiles for your whole family, birth certificates (long form) of your grandparents and a sample of your dog's DNA isn't something Apple is likely to allow. It's probably easier to get the permission to hold a punk rock concert in the command center of Cheyenne Mountain.
