[BodyTrackingColorCamera] 'Body tracker capture enqueue failed!'

[ytop0386]

Hi I tried running the exampleBodyTrackingColorCamera.py It did work, and video window was opened, but it shutdown after a while it occurred below these errors

when i tried running the exampleBodyTracking.py, these error won't happen

Did anyone know how to solve this problem? thank you lot!

Were you able to solve the issue? Sometimes I have a similar problem if the cable or the USB port is does not support enough USB speed, but not sure if it is the same issue.

Hi. I found it may appear if the capture is empty. I use the following code to jump this frame.

ret, depth_color_image = capture.get_colored_depth_image()
if not ret:
    continue

I think this has to do with https://microsoft.github.io/Azure-Kinect-Sensor-SDK/master/structk4a__device__configuration__t_a8208974f05d89fc1362c6a0900bdef4d.html

See #https://github.com/microsoft/Azure-Kinect-Sensor-SDK/issues/1416

[1]:

device_config = pykinect.default_configuration
# device_config.color_resolution = pykinect.K4A_COLOR_RESOLUTION_1080P
# device_config.depth_mode = pykinect.K4A_DEPTH_MODE_WFOV_2X2BINNED
# device = pykinect.start_device(config=device_config)

Config [1] was causing (a similar) error:

[2024-03-28 08:35:02.147] [error] [t=8488] D:\a\1\s\extern\Azure-Kinect-Sensor-SDK\src\image\image.c (51): k4a_image_t_get_context(). Invalid k4a_image_t 0000000000000000

Body tracker capture enqueue failed!

Fixed by modifying Config [1] to [2].

[2]

device_config.color_resolution = pykinect.K4A_COLOR_RESOLUTION_1080P
device_config.depth_mode = pykinect.K4A_DEPTH_MODE_NFOV_UNBINNED
device_config.color_format = pykinect.K4A_IMAGE_FORMAT_COLOR_MJPG
device_config.camera_fps = pykinect.K4A_FRAMES_PER_SECOND_30
device_config.synchronized_images_only = True`

Specifically; device_config.synchronized_images_only = True
