    there are two issues in play here:
    first of all you code is terribly wrong:

    Code (csharp):
    1.  
    2. webcamTexture = new WebCamTexture(640, 480);
    3. data = new Color32[640 * 480];
    4. webcamTexture.GetPixels32(data);
    5.  
    the extents you request are used by unity/OS ONLY as "i want something like that", so you might get totally different extents (e.g. it wont work even on editor on osx).

    second issue:

    even you would correctly query extents, there is indeed a bug with ios WebCamTexture being forced to report 16x16. That is fixed and will be backported to 5.2.something

    I don't see anything wrong with the code. Yes, the extents are hardcoded for this bug report as those values should work with iOS / iPad. Thanks for confirming the bug. Nice to hear it's fixed.
