mediarecorder

When I record video by MediaRecorder, it always records in landscape mode, regardless of real device orientation. How to force MediaRecorder/Camera use real orientation ? refer to Camera.Parameters.setRotation() for more information. There is an example there and instead of calling setRotation(rotation) try to call mediaRecorder.setOrientationHint(rotation) when recording video. Sagar Aghara Add the following two lines of code: Camera.setDisplayOrientation(90); // use for set the orientation of the preview mRecorder.setOrientationHint(90); // use for set the orientation of output video before:

I have this error. Can somebody please help me, I think it's something about touch listener... The error is happening when I release my finger. 04-25 20:07:00.263: D/FB Sessions(18429): false 04-25 20:07:04.533: I/MediaRecorderJNI(18429): prepare: surface=0x189250 (identity=1813) 04-25 20:07:10.493: E/MediaRecorder(18429): stop failed: -1007 04-25 20:07:10.493: D/AndroidRuntime(18429): Shutting down VM 04-25 20:07:10.493: W/dalvikvm(18429): threadid=1: thread exiting with uncaught exception (group=0x40018608) 04-25 20:07:10.503: E/AndroidRuntime(18429): FATAL EXCEPTION: main 04-25 20:07:10.503

That's my question :). If I start recording using the Front Camera with the MediaRecorder and then switch to the back camera, is it possible to keep recording using the same video file? Also, is it possible to record both cameras at the same time? You can do it on Nexus9 with camera2 api. (Nexus5 can't open 2 cameras at the same time) Create 2 Gl contexts(Shared) and 2 texture buffers. Create a TextureView for previewing. Create a MediaRecoder for recording. Open front and back camera. Make repeating request that output target is texture buffer. Render scene with 2 textures to TextureView's

I am recording video with MediaRecorder. My code works fine on 2.3.3 but fails on 4.0.3. The issue is following: the code mediaRecorder.stop() throws the RuntimeExeption java.lang.RuntimeException: stop failed. at android.media.MediaRecorder.stop(Native Method) with LogCat message 04-05 15:10:51.815: E/MediaRecorder(15709): stop failed: -1007 UPDATE I've found, that MediaPlayer reports an error (via MediaPlayer.OnErrorListener) almost immediately after the start. Error code is 100 (media server died), extra -1007. UPDATE 2 Code to prepare the MediaRecorder c = Camera.open(); ... // Step 1:

Is it possible in Android to record video from Camera without audio stream? Goal: to reduce the output file size. You can use a MediaRecorder without calling setAudio* on it. This is my first time using MediaRecorder, but this example seems to work: public class CamcorderView extends SurfaceView implements SurfaceHolder.Callback { private SurfaceHolder mHolder; private Camera mCamera; private MediaRecorder mRecorder; public CamcorderView(Context context, AttributeSet attrs) { super(context, attrs); mHolder = getHolder(); mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); mHolder

The Android MediaRecorder has a function .getMaxAmplitude(); which, as the API tells me, "Returns the maximum absolute amplitude that was sampled since the last call to this method." but I can't find what amplitude this is? Is it in pascal or watts? I have found on several pages on the web that you can calculate a value closely corelated to decibels using (as suggested here ). double db = (20 * Math.log10(amplitude / REFERENCE)); which would let me assume that the returned value is in some linear scale (probably something like milipascal...) REFERENCE=0.1 (I am aware that this should be
