Title: GStreamer jpegparse caught SIGSEGV
Hi there,

I was trying to do a Logitech BRIO 4K webcam streaming by the following GStreamer pipeline:

GST_DEBUG=3 gst-launch-1.0 v4l2src device=/dev/video9 ! "image/jpeg,width=(int)3840,height=(int)2160,framerate=(fraction)30/1" ! mppjpegdec ! kmssink sync=false

Although it usually worked fine, I wanted to add a jpegparse into the pipeline to make sure every frame mppjpegdec got would be parsed.

Unfortunately, when I tested this pipeline:

GST_DEBUG=3 gst-launch-1.0 v4l2src device=/dev/video9 ! "image/jpeg,width=(int)3840,height=(int)2160,framerate=(fraction)30/1" ! jpegparse ! mppjpegdec ! kmssink sync=false

or this pipeline:

GST_DEBUG=3 gst-launch-1.0 v4l2src device=/dev/video9 ! "image/jpeg,width=(int)3840,height=(int)2160,framerate=(fraction)30/1" ! jpegparse ! fakesink

I got "Caught SIGSEGV" error.

Does anyone have an idea? Thanks in advance!

Platform: ROC-RK3566-PC_Buildroot_v1.2.4a
Kernel version: 4.19.232
GStreamer version: 1.20.0
