MediaRecorder video capturing in portrait mode

Question

I\'m try to make custom video app. Iwork using settings in manifest 2.2 only (API 8).

All goes well but I don\'t understand why portrait mode video does

Answer 1

Found it ! Indeed, you can change the preview, you can tag the video, but there's no way to actually change the video... (maybe a speed issue or something)

camera.setDisplayOrientation(90);

To rotate the preview, then

recorder.setOrientationHint(90);

To tag the video as having a 90° rotation, then the phone will automatically rotate it when reading.

So all you have to do is

            camera = Camera.open();
        //Set preview with a 90° ortientation
        camera.setDisplayOrientation(90);
        camera.unlock();

        holder = getHolder();
        holder.addCallback(this);
        holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

        recorder = new MediaRecorder();
        recorder.setCamera(camera);
        recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
        recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
        recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
        recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
        recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
        recorder.setOutputFile(getVideoFolder()+rnd.nextString()+".mp4");
        recorder.setPreviewDisplay(holder.getSurface());
        //Tags the video with a 90° angle in order to tell the phone how to display it
        recorder.setOrientationHint(90);

        if (recorder != null) {
            try {
                recorder.prepare();
            } catch (IllegalStateException e) {
                Log.e("IllegalStateException", e.toString());
            } catch (IOException e) {
                Log.e("IOException", e.toString());
            }
        }

        recorder.start();

Hope it helps ;-)
