I tried so many solution, but no any one doesn't work. This is my simple code for just get result (rtsp stream). It working without error, but I cant open rtsp stream.
And second question how to set stream name like rtsp://192.168.1.158:8554/test
First what I do, get camera's frame format from Basler camera 2. Creating video capturing 3. Getting current IP 4. Configuring pip_out string for rtsp streaming 5. Creating opencv writer 6. Read frame from camera and doing yolo detections (here not showed) 7. Showing result on local machine 8. Write frame to rtsp
VLC doesn't connect to rtsp. When I tried open it on local machine like this:
gst-launch-1.0 rtspsrc location=rtsp://localhost:8554 latency=100 !
queue ! rtph264depay ! h264parse ! avdec_h264 !
videoconvert ! videoscale ! video/x-raw,width=640,height=480 !
Xvimagesink
It give me follow error:
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Progress: (open) Opening Stream
Progress: (connect) Connecting to rtsp://localhost:8554
ERROR: from element /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0: Could not > open resource for reading and writing.
