Random Gstreamer pipeline crash in libcamerasrc

[sarathy86]

Random Gstreamer pipeline crash in libcamerasrc using with RPi5 and IMX477 HQCam.

Below is the error i am getting in log

** (node:27357): CRITICAL **: 03:04:26.117: void GstLibcameraSrcState::requestCompleted(libcamera::Request*): assertion 'wrap->request_.get() == request' failed

Below is the pipeline i am using

gst-launch-1.0 libcamerasrc ! video/x-raw,colorimetry=bt709,format=NV12,width=3840,height=3040,framerate=10/1 ! queue name=q1 ! videoconvert ! jpegenc quality=80 ! multifilesink max-files=1 location=/mnt/ramdisk/tmp.jpg

Can someone point to the reason for this assertion? Any race condition could cause this?

I suspect requestCompleted gets called before queuedRequests_.push(std::move(wrap)), is there a rare possibility of that with thread switching in place?

Unfortunately I know next to nothing about gstreamer and the libcamerasrc component. I think this might be worth posting to the libcamera developer mailing list. You will get more capable eyes looking at it and helping you out.
