我想同时录制屏幕和从前置摄像头录制视频。可能吗。我尝试过它给媒体发布例外。只有两个作品之一
public void setupRecorder(int resultCode, Intent data) {
NativeAppRecordingService.dataIntentScreenCapture = data;
NativeAppRecordingService.resultCodeDataScreenCapture = resultCode;
NativeAppRecordingService.recorder.reset();
recordingInfo = getRecordingInfo();
NativeAppRecordingService.recorder.setVideoSource(SURFACE);
// Enable Audio recording.......
NativeAppRecordingService.recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
NativeAppRecordingService.recorder.setOutputFormat(MPEG_4);
NativeAppRecordingService.recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
NativeAppRecordingService.recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
NativeAppRecordingService.recorder.setVideoSize(recordingInfo.width, recordingInfo.height);
NativeAppRecordingService.recorder.setVideoEncodingBitRate(15 * 1000 * 100);/**change this for video quality */
NativeAppRecordingService.recorder.setVideoFrameRate(recordingInfo.frameRate);
//String outputVideoFileName = fileFormat.format(new Date());
NativeAppRecordingService.recorder.setOutputFile(Utils.getOutputVideoFileNameForAmazonS3Bucket(""));
// NativeAppRecordingService.recorder.setOutputFile(NativeAppRecordingService.video_file.getAbsolutePath());
try {
NativeAppRecordingService.recorder.prepare();
NativeAppRecordingService.projection = NativeAppRecordingService.manager.getMediaProjection(resultCode, data);
Surface surface = NativeAppRecordingService.recorder.getSurface();
if (surface == null) {
Toast.makeText(StartRecorderActivity.this, "Your device is not able to capture screen!", Toast.LENGTH_SHORT).show();
File f = new File(Utils.getOutputVideoFileNameForAmazonS3Bucket(""));
if (f.exists()) {
f.delete();
}
// TODO if decive is not able to capture audio and video
// todo cancel the test
TerminatingTest();
} else {
NativeAppRecordingService.display = NativeAppRecordingService.projection.createVirtualDisplay(NativeAppRecordingService.DISPLAY_NAME,
recordingInfo.width, recordingInfo.height,
recordingInfo.density, VIRTUAL_DISPLAY_FLAG_PRESENTATION,
surface, null, null);
NativeAppRecordingService.recorder.start();
// todo PauseRecording
NativeAppRecordingService.isRecording = true;
finish();
}
} catch (IllegalStateException e) {
e.printStackTrace();
Toast.makeText(StartRecorderActivity.this, "Your device is not able to capture screen!", Toast.LENGTH_SHORT).show();
File f = new File(Utils.getOutputVideoFileNameForAmazonS3Bucket(""));
if (f.exists()) {
f.delete();
}
// TODO if decive is not able to capture audio and video

TerminatingTest();
} catch (IOException e) {

}
// TODO if decive is not able to capture audio and video

TerminatingTest();
}
}
上面是屏幕录制，下面是视频录制
public static void setUpVideoRecorder() {
try {
mMediaRecorder = new MediaRecorder();
mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);
mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
/**
* create video output file
*/
video_file = getOutputMediaFile();
/**
* set output file in media recorder
*/
mMediaRecorder.setOutputFile(video_file.getAbsolutePath());
mMediaRecorder.setMaxDuration(300000);
CamcorderProfile profile = CamcorderProfile.get(CamcorderProfile.QUALITY_480P);
mMediaRecorder.setVideoFrameRate(profile.videoFrameRate);
mMediaRecorder.setVideoSize(profile.videoFrameWidth, profile.videoFrameHeight);
mMediaRecorder.setVideoEncodingBitRate(profile.videoBitRate);
mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);
mMediaRecorder.setAudioEncodingBitRate(profile.audioBitRate);
mMediaRecorder.setAudioSamplingRate(profile.audioSampleRate);
/* int rotation = windowManager.getDefaultDisplay().getRotation();
switch (mSensorOrientation) {
case SENSOR_ORIENTATION_DEFAULT_DEGREES:
mMediaRecorder.setOrientationHint(DEFAULT_ORIENTATIONS.get(rotation));
break;
case SENSOR_ORIENTATION_INVERSE_DEGREES:
mMediaRecorder.setOrientationHint(INVERSE_ORIENTATIONS.get(rotation));
break;
}*/
mMediaRecorder.prepare();
}
catch (IOException ioe)
{
Log.e(TAG,"setUpVideoRecorder ioe "+ioe);
}
}
这是LogCat
