I downloaded DS 3.0 and I am trying to use the dewarper plugin.
I have started with the example given in the documentation, which works well:
gst-launch-1.0 filesrc location=streams/sample_cam6.mp4 ! qtdemux ! h264parse ! \ nvdec_h264 ! nvvidconv ! nvdewarper config-file=configs/deepstream-app/config_dewarper.txt ! \ m.sink_0 nvstreammux name=m width=960 height=752 batch-size=4 ! nvmultistreamtiler ! nveglglessink
I just can’t understand the type of data at the output of the dewarper. According to the documentation, it is a buffer containing four “surfaces”.
In my use case, I only need two surfaces, with different processings. How can I extract those two frames from the four provided?
I already tried some combinations of nvstreammux / nvstreamdemux with no result, and gst-inspect didn’t helped so far.
Thank you for your help.
