RadWebCam: add preview orientation on win 10 tablet pc



I am using the WebCam Control in WinForms (latest Version) and placed it on an empty form. Then I tested this "program" on a Test device (CAT T20 Win10 Tablet). The preview picture in the control does not match the orientation of the device. (depending on which side of the device is at top the visible picture is rotated 90/180 degrees).

For testing purposes I installed the WinForms Example application on the same tablet device with the same results.

How to sync the captured picture to the orientation of the device? In the WPF documentation of the WebCamControl I found a Videoflip method, which is not available in WinForms.

Best regards,

Hey Stefan,

Have you had a play with the roll settings of the camera? I recently received a prototype kiosk and the image from the front-facing camera was upside down, setting roll to 0 was the correct orientation (both up the right way and the right to left so that text was readable if I held something up to it), by default I think it was/is set to 3 for my camera.

I added the following code (thanks to the support team) after initialization and before I called Start...


            FieldInfo fi = typeof(RadWebCam).GetField("player", BindingFlags.Instance | BindingFlags.NonPublic);
            var player = fi.GetValue(this.radWebCam1);
            var mediaSettingsViewModel = player.GetType().GetMethod("GetCameraSettingsViewModel", BindingFlags.Instance | BindingFlags.Public).Invoke(player, new object[] { true });

            var camSettingsViewModel = (IEnumerable<object>)mediaSettingsViewModel.GetType().GetProperty("CameraViewModel", BindingFlags.Instance | BindingFlags.Public).GetValue(mediaSettingsViewModel, null);
            var rollSetting = (camSettingsViewModel.ToList()[6]); // Rool option 
            PropertyInfo pi = rollSetting.GetType().GetProperty("Value", BindingFlags.Instance | BindingFlags.Public);
            var val = pi.GetValue(rollSetting);
            pi.SetValue(rollSetting, 0); // from 0 to 3

Hello, Stefan,

Currently, RadWebCam doesn't support video rotation. However, it seems to be a reasonable request: https://docs.microsoft.com/en-us/windows/win32/medfound/mf-mt-video-rotation
