As with other developers here, I wanted to instrument an accelerated pipeline running on the Nano. I compiled and installed GStShark, and I was able to obtain output from the example pipeline shown in the documentation.
I then tried to instrument a live src pipeline ( USB camera ) to overlay output. When I did this, once the pipeline gets to PLAYING state, the pipeline appears to freeze, I get no more output from GStShark and I have to CTRL C to exit the pipeline.
The pipeline I am using is shown below for reference.
gst-launch-1.0 -v v4l2src device=/dev/video0 !
‘video/x-raw,width=640, height=480, framerate=30/1, format=YUY2’ !
nvvidconv ! ‘video/x-raw(memory:NVMM),format=NV12’ ! omxh264enc ! h264parse ! omxh264dec !
Before running I did
has anyone else run into this problem when trying to use GStShark to instrument an actual pipeline.
Is there something obviously wrong that I am doing
P.S. Pipeline without the exports ( so no GStShark tracers enabled) runs as expected
