WP8 set preview resolution

On my Lumia 920 GetAvailablePreviewResolutions() returns that the following 4 resolutions are available for the target device:

  • 1280x720
  • 1024x768
  • 800x448
  • 640x480

but SetPreviewResolutionAsync() accepts only 1024x768. For the other three (supported) resolutions it throws an exception

System.ArgumentException: Value does not fall within the expected range.

I have restarted my phone but it doesn't seem to help either.

==========================================================================

For future developers who face the same problem, below are my findings.

Nokia Lumia 920 supports the following 6 capture resolutions (with their corresponding aspect ratio):

3264X2448        4:3;
3552X2000       16:9;
2592X1936        4:3;
2592X1456       16:9 ;
2048X1536        4:3 ;
640X480          4:3 ;

and following 4 preview resolutions (with their corresponding aspect ratio):

1280X720        16:9; 
1024X768         4:3 ;   
800X448         16:9 ;    
640X480          4:3;

for 16:9 aspect ratio capture_resolutions use only the 16:9 preview_resolutions.
