Intent wrapperIntent = Intent.createChooser(intent, null);
((Activity) context).startActivityForResult(wrapperIntent, requestCode);
//添加音频
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType(contentType); //String VIDEO_UNSPECIFIED = "video/*";
Intent wrapperIntent = Intent.createChooser(intent, null);
((Activity) context).startActivityForResult(wrapperIntent, requestCode);
//拍摄视频
int durationLimit = getVideoCaptureDurationLimit(); //SystemProperties.getInt("ro.media.enc.lprof.duration", 60);
Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0);
