Grab RTSP stream from ip camera
Hello,
Have anyone tried to grab the rtsp image stream from ip camera with gstreamer gscam node? And If yes what GSCAM_CONFIG used?
I have successfully grabbed stream with video_stream_opencv pkg. However the resource consumption is very high, and I want to check maybe with gscam will be lighter for CPU.
Thanks!
ok what gstreamer pipeline did you try for gscam? With the rtspsrc element probably?
@Humpelstilzchen Hi , yes rtspsrc. I have tried this line:
rtspsrc location=rtsp://admin:Admin2020@192.168.57.201 latency=100 ! queue ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! videoscale ! video/x-raw,width=640,height=480 ! autovideosink -- working
Does the node which you have provide stream video? or receive? Because I want to get the video
gscam adds an appsink element to the pipeline, and uses the appsink API to pull image data and publish ROS image messages. I am not sure what you mean by "get the video".
@clyde By "get the video", I want exactly what you mentioned. I want grab the stream and publish it to ROS.

gst-launch-1.0 rtspsrc location=rtsp://admin:Admin2020@192.168.57.201 latency=100 ! queue ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! videoscale ! video/x-raw,width=640,height=480 ! autovideosinkworks, then this GSCAM_CONFIG should also work:rtspsrc location=rtsp://admin:Admin2020@192.168.57.201 latency=100 ! queue ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! videoscale ! video/x-raw,width=640,height=480To your original question, I don't know how CPU usage compares to
video_stream_opencv.
