SDK I would say. I'm recording video using UIImagePickerController. I then want to extract the audio to do some processing on it. I know we could just record audio, but we want the video too so we would like to record the video, and then process it on the iphone.
Does anyone have any idea how to extract audio from recorded video.
Hello guys,
check out this nifty toolkit to extract audio. For example, give it a try for extracting music from youtube. If you get it, it proves that you are able to extract audio from any recorded video.
Use ffmpeg, open the video with av_open_file_input
get the index to the video segments
put the samples into the audio buffer
copy the samples from the buffer sequentilly to a new file.
Hi Michell,
I am trying to convert .mov to .mp4. I am able to convert video but audio is having issues. Should i only decode audio and copy raw data in output file or i have to encode audio as well. I am trying output example.c code with no luck. It would great if you have any sample.
this will let you choose a video file as an input and if under the "TO" field you select mp3 or whatever audio format it will just rip the audio to a standalone file.

I was talking to do this programmatically after compiling and integrating ffmpeg libraries for ios 4.3 and then converting .mov files in to .mp4 files in IPhone. I am able to convert video but facing issue to integrate audio.
