Demultiplexar a Video

[dromerobarria]

Hello.

I understand that with ffmpeg it is posible to extract data from a video, but i don't know if with this framework it is posible in iOS, cause im looking to extract the data of a video like Demultiplexar (i don't know it is the same word in english, maybe it is decode the word or remuxing). So I ask , It is posible? and if it is .. how can i do it? or at least in which part of the project can i find how to do it .

Thanks in advance and keep this nice work.
