title: Android: Demux MP4 into video and audio?
body: <p>I need to demux an MP4 file into video and audio to do some editing on the audio. I don't want to use FFMPEG, I've already attempted to use it once and it went horribly. How would I go about demuxing? From google searches, it seems like there isn't even a way to do it. Nothing ever comes up. I was thinking of converting an MP4 into an MP3, editing that and then adding that audio onto the original MP4 using MP4Parser, how can I edit the MP3? Absolutely any help is appreciated, I have no idea where to go from here.</p>
