Question

Im Trying to do something simple, record audio and video without preview.

Here is my code:

MediaRecorder mediaRecorder = new MediaRecorder();

// Configure the input sources
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

// Set the output format
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);

// Specify the audio and video encoding        
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);

    //Specify the outputfile
    mediaRecorder.setOutputFile("/sdcard/Video/myoutputfile.mp4");

mediaRecorder.start();

In the AndroidManisfest.xml:
<user-permission android:name="android.permission.RECORD_AUDIO" />
<user-permission android:name="android.permission.RECORD_VIDEO" />

This stops the application when it launches.

Anyone has any ideia?

Answer 1

try to call this before you start the record;

mediaRecorder.prepare();

Also, keep in mind you are missing a few necessary “features” you must set before calling prepare.
Here seems to be a few methods you are missing;

setPreviewDisplay();
setMaxDuration((int) #); 
setOnInfoListener();
setVideoSize(#, #); 
setVideoFrameRate(15);
