在没有音频的情况下在android中录制视频

Question

I'm working on a project and I'm curious to know if its possible to configure the MediaRecorder in Android to record just the video and exclude audio, ie

mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
mRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

changed to something along the lines of

mRecorder = new MediaRecorder();
mRecorder.setAudioSource(null);
mRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

When I try to do the above, I get different exceptions when I either try to initialize the MediaRecorder or when I try to start the recording.

According to the documentation , it would seem that I can do this.

If this method is not called, the output file will not contain an audio track.

Answer 1

The issue I was having was a result of using a CamcorderProfile . Once that was removed, I no longer had issues building the project. As CodeX mentioned, there is no need to have an audio source.
