Get depth buffer from the capture handle failed!

[derivativerobmc]

I am getting occasional failures when trying to obtain both the color image and body index from a Femto Mega camera. When it gets in this mode it stops receiving any images and I have to restart the system.

This is happening with the latest 1.10.8 version of the Orbbec SDK and version 1.10.1 of the K4A wrapper. Our users have also reported this in the 1.9 SDKs and with the Femto Bolt camera.

Could this be an issue of having frame sync off? If it receives a color frame without a depth frame?

You can set synchronized_images_only in k4a_device-configuration_t to ensure that all frame data is received simultaneously in one frameset. Otherwise, you will need to manually check it yourself
