Android: Processing video and sound on phone

I want to merge a sound file and a video file (remove the sound from the video file and replace it with my own sound) and this should happen on the phone. I have done this through f开发者_运维问答fmpeg, but I can't do that now.

Any help appreciated, 10x, Danail

Your only hope of doing that will involve using the NDK to create a C/C++ library, perhaps leveraging ffmpeg logic. Or, perhaps find an ffmpeg ARM port and run it via Runtime.exec().

In reality, I am skeptical that a phone CPU will do this very quickly.
