How to capture video in Android?
android, video-capture
Solution
Here is a snippet that works:
m_recorder = new MediaRecorder();
m_recorder.setPreviewDisplay(m_BeMeSurface);
m_recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
m_recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
m_recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
m_recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
m_recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
m_recorder.setMaxDuration((int) MAX_TIME);
m_recorder.setOnInfoListener(m_BeMeSelf);
m_recorder.setVideoSize(320, 240);
m_recorder.setVideoFrameRate(15);
m_recorder.setOutputFile(m_path);
m_recorder.prepare();
m_recorder.start();
THE most important thing is the surface. You don't have it, so without it it fails.

Problem
I would like to create a video recorder and so far haven't figured out how to set parameters in order to successfully go through MediaRecorder.prepare() method. Executing the following method ``` public void start() throws IOException{ String state = android.os.Environment.getExternalStorageState(); if(!state.equals(Environment.MEDIA_MOUNTED)) { throw new IOException("SD card is not mounted. It is " + state + "."); } File directory = new File(path).getParentFile(); if(!directory.exists() && !directory.mkdirs()) { throw new IOException("Path to file could not be created."); } recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263); recorder.setVideoFrameRate(15); recorder.setVideoSize(176, 144); recorder.setOutputFile(path); recorder.prepare(); recorder.start(); this.state = VideoRecorderState.STATE_RECORDING; } ``` it throws an exception on line `recorder.prepare().` How to set parameters in order to be able to capture video?
