VLC by is a popular multi-format video and audio player for a wide variety of systems. Within the past few days I have successfully ported over VLC to the Apple iPhone and iPod Touch. I have also built and used my ogg4iphone frontend for vlc4iphone.
What is vlc4iphone capable of? At the moment it may be limited by only a small handfull of decoders, but soon that list will grow! It currently allows you to drag and drop the following popular media formats onto your iPhone/iPod Touch for playback: MPEG / MPG,AVI,MP3. It also supports some lesser known media formats.
Soon it will play: FLAC,OGG
I am also researching playback of: VCD,DivX,WMA,WMV
Currently vlc4iphone is only available to ZodTTD.com Beta Testers though as more decoders get implemented and some bugs fixed up, a public release will be made with source code found at my git repo in the downloads section of the forum. This should all happen very soon.
