k4a_image_get_size() returns unexpected values
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):
