I am creating a video player that supports video from multiple formats and i cant play video from .wmv format.
So when i try to run .wmv file in different video player packages, formats like(mp4,3gp..) supports except .wmv file and it says "Track cant be played". Any idea on how to do is appreciated. Thank you.
The .wmv format is not supported on a lot of browsers. You'll probably have to just scrap the idea of including that format.

The easiest way to convert your audio files is by using the EXTAudioFileConvert API from Apple.
Tutorial on using the EXTAudioFileConvert can be found at: Easy AAC compressed audio conversion on iOS.
What is the best way to upload a ~700MB of AVCHD (1080p, 50fps) video file to facebook to get the best performance?
Uploading it the regular way gets video and audio out of sync, and the video appears "stuttering"...
Maybe convert it to so some sort of format?
Thanks!

Can anybody help me with mp3 files.
Thanks
With ffmpeg you're also able to convert mp3-files only (no video).
Just use:
ffmpeg -i yourmp3.mp3 ...your arguments... output.mp3
To add to Tim's answer, HLS supports mp3 codec. So if your audio is already in mp3, all you would need is the segmenter
in my apps im able downloaded a short video file from my server using NSURLConnection but the data i received is in data format which cannot be played using MPMoviePlayerViewController. My question is: it is possible to convert NSdata to mp4 file? and how do i play it using MPMoviePlayerViewController. would really appreciate some code snippets cos i'm at a lost. Thanks in advance.
Look at AVAssetWriter. This allows you to encode image frames and audio into a MOV or MP4 file using hardware-accelerated methods where possible.
