Hello, 

I'm using a flir boson camera with the voxl2. The image type passed from voxl-uvc-server to ROS is NV12 (or NV21), and the output image from the voxl_mpa_to_ros package is YUV422. Is there any way to get the image format in MONO8 or MONO16? 

Thanks,
Mia

The first width x height bytes of NV21 and NV12 are the 8-bit luminance values (mono). So, you should be able to publish MONO8 pretty easily with a little extra code.
