I'm creating a web system wherein the user can view the videos of AVI format. Is there any way to do this without making use of codecs? I want this to be hassle free for the users that even if the user uses a Mac or a windows or Linux-based puter, he/she can still view the videos.

the videos are saved on my web server and I just have to access their URL as the source of the video. These videos are in AVI format since these videos are taken from the Pepper, the robot by Aldebaran.

Can anyone help? Thanks
