Hi！
deepstream_python_apps many examples of video stream analysis are provided here, but I want to analyze pictures. I input a picture and get the analysis results. The following is the pipeline I wrote, but it always reports errors. How can I modify it?
GObject.threads_init()
Gst.init(None)
print("Creating Pipeline \n ")
pipeline = Gst.Pipeline()
if not pipeline:
sys.stderr.write(" Unable to create Pipeline \n")
print("Creating Source \n ")
source = Gst.ElementFactory.make("filesrc", "file-source")
if not source:
sys.stderr.write(" Unable to create Source \n")
source.set_property('location', "./1.jpg")
pipeline.add(source)
decoder = Gst.ElementFactory.make("jpegdec", "vorbis-decoder")
if not decoder:
sys.stderr.write(" Unable to create Source \n")
pgie = Gst.ElementFactory.make("nvinfer", "primary-inference")
if not pgie:
sys.stderr.write(" Unable to create pgie \n")
pgie.set_property('config-file-path', "config_infer_primary_peoplenet.txt")
pipeline.add(pgie)
print("Creating filter1 \n ")
caps1 = Gst.Caps.from_string("image/jpeg,,framerate=(fraction)30/1")
filter = Gst.ElementFactory.make("capsfilter", "filter")
if not filter:
sys.stderr.write(" Unable to get the caps filter \n")
filter.set_property("caps", caps1)
pipeline.add(filter)
nvvidconv = Gst.ElementFactory.make("nvvideoconvert", "convertor")
if not nvvidconv:
sys.stderr.write(" Unable to create nvvidconv \n")
pipeline.add(nvvidconv)
# Create OSD to draw on the converted RGBA buffer
nvosd = Gst.ElementFactory.make("nvdsosd", "onscreendisplay")
if not nvosd:
sys.stderr.write(" Unable to create nvosd \n")
pipeline.add(nvosd)
sink = Gst.ElementFactory.make("fakesink", "nvvideo-renderer")
sink.set_property('enable-last-sample', False)
pipeline.add(sink)
print("Linking elements in the Pipeline \n")
source.link(decoder)
decoder.link(pgie)
pgie.link(nvvidconv)
nvvidconv.link(nvosd)
nvosd.link(sink)
# create an event loop and feed gstreamer bus mesages to it
loop = GObject.MainLoop()
bus = pipeline.get_bus()
bus.add_signal_watch()
bus.connect("message", bus_call, loop)
# start play back and listen to events
print("Starting pipeline \n")
pipeline.set_state(Gst.State.PLAYING)
try:
loop.run()
except:
pass
# cleanup
pipeline.set_state(Gst.State.NULL)
