Set video recording Frame Rate to 1 on Android

Question

I'm am capturing a video from the Android camera. However, I would like to set the frame rate to 1 frame per second.

If I add the setVideoFrameRate(1), then the video cannot be recorded properly. If I don't set this value, recording works correctly.

This is my code...

mediaRecorder = new MediaRecorder();
mediaRecorder.setCamera(camera);                
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);

mediaRecorder.setOutputFile(GetOutputMediaFileDir(VIDEO_TYPE,intVideoIndex));
mediaRecorder.setVideoSize(640,480);

mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
//  mediaRecorder.setCaptureRate(1);
mediaRecorder.setVideoFrameRate(1);
mediaRecorder.setMaxDuration(10000);
mediaRecorder.setOnInfoListener(this);
mediaRecorder.setPreviewDisplay(surfaceView.getHolder().getSurface());

mediaRecorder.prepare();
mediaRecorder.start();

Basically I need to reduce the size of video since I have to send it on a phone which may be using 3G network. The longest video will be 1 minute so it will take a long time to send the video.

Could someone please help me with this problem.

Answer 1

20 - 24 frames per second is the absolute minimum for a video to maintain any sort of quality. 1 Frame per second is not supported because it would be more of a slideshow. Also, the sound associated with the video would not be able to sync correctly.

Answer 2

frame rate 5 is supported in many devices.you can use getSupportedPreviewFpsRange() for finding supported frame rate.
