Webcam streaming using gstreamer over UDP

Here is what I'm trying:

gst-launch -v udpsrc port=1234 ! fakesink dump=1

I test with:

gst-launch -v audiotestsrc ! udpsink host=127.0.0.1 port=1234

And everything works fine, I can see the packages arriving from the audiotestsrc

Now lets test with the w开发者_Python百科ebcam source:

gst-launch -v v4l2src device=/dev/video0 ! queue ! videoscale method=1 ! "video/x-raw-yuv,width=320,height=240" ! queue ! videorate ! "video/x-raw-yuv,framerate=(fraction)15/1" ! queue ! udpsink host=127.0.0.1 port=1234

And nothing happens, no package appears in the dump.

Here is a logdump of what verbose shows in the server.

Does anyone have a clue on this?

Try these (You may have to install gstreamer-ugly plugins for this one)

UDP streaming from Webcam (stream over the network)

gst-launch v4l2src device=/dev/video0 ! 'video/x-raw-yuv,width=640,height=480' !  x264enc pass=qual quantizer=20 tune=zerolatency ! rtph264pay ! udpsink host=127.0.0.1 port=1234

UDP Streaming received from webcam (receive over the network)

gst-launch udpsrc port=1234 ! "application/x-rtp, payload=127" ! rtph264depay ! ffdec_h264 ! xvimagesink sync=false

Update

To determine the payload at the streaming end simply use verbose option with gst-launch -v ...

Maybe packets are too large for udp? They are limited to 64K. Try resizing frames to really small size to check if this is the reason. If so, you may be interested in some compression and payloaders/depayloaders (gst-inspect | grep pay).

gstreamer1-1.16.0-1.fc30

gst-launch-1.0 -v filesrc location=/.../.../.../sample-mp4-file.mp4 ! qtdemux ! h264parse ! queue ! rtph264pay config-interval=10 pt=96 ! udpsink port=8888 host=127.0.0.1
