And here I will share a method how to view AVI files on iPhone 5S in a simplest way.
Basically such error's occur due to inappropriate format of video file or due to corrupted file. So you first check weather your iPhone 5S is able to play that format of video clip or not. And far as I know iPhone 5S like other Apple devices can’t support AVI format natively. One of the solutions is to use external Video player for playing that video's. You can get video player's from Apple App Store and you can easily download them from there. Note: I can’t make sure it goes smoothly all the time. Some problems exist like no audio. That’s mainly due to its complex video/audio codecs.
Also you can encode AVI video's to iPhone 5S compatible format like MP4, MOV, M4V by using video encoding tool's. Brorsoft Video Converter for Mac is the ideal utility for you.
