How to convert iphone's caf to ogg on ubuntu
24 novembre 2012, par Amure Pinho - Syncmobilei really need your support to solve that problem :
We developed an iOS application that sends a sound file to our server and then, we share this audio.
The problem is we didnt find any solution to convert the audio inside the iOS.
We tought : Ok, thats a problem, but we can still convert the audio in the server right ?
We are trying to make this using afconvert, ffmpeg but with no sucess.
Do you have any basic guide or hint so we can write this in our server application and convert all the .CAF files to another format like OGG or MP3 ?
Thanks a lot !

Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)It’s only happening for mov files. There are couple of tricky places it looks like it’s trying to take screenshot from a video.
Maybe anyone witnessed anything similar and can give me a tip ?
