Coral Dev Mini Support - PVR Error

[chunyeow]

Description

I have tried to modify the gstreamer pipeline using examples-camera/gstreamer as follow:

            scale_caps = 'video/x-raw,format=BGRA,width={w},height={h}'.format(w=src_size[0], h=src_size[1])
            PIPELINE += """ ! decodebin ! queue ! v4l2convert ! {scale_caps} !
              glupload ! glcolorconvert ! video/x-raw(memory:GLMemory),format=RGBA !
              tee name=t
                t. ! queue ! glfilterbin filter=glbox name=glbox ! queue ! {sink_caps} ! {sink_element}
                t. ! queue ! glsvgoverlay name=gloverlay sync=false ! glimagesink fullscreen=true
                     qos=false sync=false
            """

However, when running the "python3 detect.py --tracker sort", the following error occurred:

(1795) PVR:(Error): ScheduleTA: Skipping render from different gc/thread! [ :0 ]

Any ideas on the PVR error?

@chunyeow Can you please let me know what is the objective of this pipeline change ?

[chunyeow]

@manoj7410 Currently, it is not able to support Coral Dev Mini, nope?

[manoj7410]

@chunyeow yes, this demo doesn't currently work on Dev Board mini. I have made some modifications locally but yet to test them. will try to merge the changes soon and will notify you.

@manoj7410 mind to share over the branch, I can do the testing as well.
