How to video record with specific sound programmatically in android?

Question

I have created functionality to record video in my app.

When I play a song, that song is recorded with video and a video file is created, similar to a dubshmash app

Answer 1

You can use a MediaRecorder without calling setAudio* on it. remove this line

mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
