k4a_image_get_size() returns unexpected values

[denniskb]

Expected behavior

k4a_image_get_size() should return:

• The size in bytes of the JPEG-encoded image, (format==MJPG)
• k4a_image_get_width_pixels() * k4a_image_get_height_pixels() * 4, (format==BGRA)
• k4a_image_get_width_pixels() * k4a_image_get_height_pixels() * 2, (format==YUY2)
• k4a_image_get_width_pixels() * k4a_image_get_height_pixels() * 1.5, (format==NV12)

Observation

Most of the time, the above is true. However, sporadically, k4a_image_get_size() returns a size that is less than the expected quantity for formats YUY2 and NV12. For example, I observed these values for a resolution of 720p and the YUY2 format (every few seconds/every few hundred frames):
