MJPEG decode failed: -1

and it goes on forever? I just reset the device and it works after. It doesn’t happen too often but sometimes it does and I find it interesting/annoying. 😃

I guess I’m luckier, I have the unit at home… 😃 Got it, makes sense. And I’m not keeping images indefinitely… after some investigation, it seems to be an issue with K4A, not about freeing buffers.

See here : https://github.com/microsoft/Azure-Kinect-Sensor-SDK/issues/1187

I will try to investigate the work to not using BGRA as a format in the capture, or at least what it means in this python package. I’m not super familiar with C/C++ so it might be a bit challenging for me but I can take a stab if I can’t mitigate the issue.

Hey if MJPEG decoding is still a problem, you can try directly getting compressed MJPEG color images now: https://github.com/etiennedub/pyk4a/pull/38
