How do I get an avi file to autoplay on a CD-ROM I burned it to? [PC only!]
Cover disks off magazines often have video snippets on and the CD or DVD autoplays when loaded into a PC.
How does this work?
The simple answer is the presence of two extra files along with the AVI video clip, one being autorun.inf and the other being a loader for the video file.
When a CD is loaded into the PC it reads the autorun.inf and does what the file tells it to do - in this case, run the loader and then play the video.
There are numerous loader programs around but a good free one is WinOpen which can be found at http://www.duckware.com/winopen/index.html
The syntax of autorun.inf is simple -
So burn WinOpen.exe, autorun.inf and your video clip to the root of a CDROM and there you are - an auto playing video.
One final point, - some users, especially corporate PCs, turn autoplay off on their systems as it is sometimes considered a security risk. If autoplay is off, then there is no way to magically play video without user interaction.
