Tonido clients (Web browser, iPhone, iPad Apps, Android Apps) can play video files without downloading the video (a.k.a streaming). In most cases, the natively supported format (such as mp4 in the case of iOS) will play from any Tonido server. But depending on the Tonido server and client, additional formats can also be streamed. Read the following for more details.
For Web Browser
Tonido uses VLC plugins and a variety of other available plugins on the browser to playback content. Most video will playback, but some may not. It depends upon the video format.
It is recommended to install VLC application that contains the browser plugins (Mozilla and IE) to playback video.
iOS devices (iPhone, iPad and iPod)
