What video formats can I use loading from the streaming assets folder?

Im am loading files form the Streaming Assets folder dynamically using the WWW class. I have only been successful with the .ovg format. I can’t load any mp4 videos. I have tried a lot of different settings but with no luck, I just get a grey screen.

Any help will be appreciated.

Thanks!

I can’t get mov or mp4 to play in unity - pro

Ogg theora is the only format supported by unity at runtime. otherformats only work in the editor where they are converted to ogg theora.
