Record UDP stream

[Gary Gilbreath]

You need to split the stream in two with the tee and queue elements.
Here's an example of a working video pipeline that displays and records simultaneously:
gst-launch-1.0 rtspsrc location=rtsp://127.0.0.1:8554/front latency=0 ! tee name=t t. ! queue ! rtph264depay ! avdec_h264 ! fpsdisplaysink sync=false t. ! queue ! rtph264depay ! h264parse ! mpegtsmux ! filesink location="ts.mpg"
You will need to modify it to work with RTP, but that is straightforward. Note that you don't have to re-encode with x264enc unless you want to, but you do need to parse it and wrap it in a muxer.

 Subject: Record UDP stream
   
Hi, I'm a gstreamer newbie.

I would like to see and record a UDP stream from my camera.

I use for see

C:\gstreamer\1.0\x86_64\bin\gst-launch-1.0.exe -e -v udpsrc port=5000 !
application/x-rtp, payload=96 ! rtpjitterbuffer ! rtph264depay ! avdec_h264
! fpsdisplaysink sync=false text-overlay=false

and this for record

C:\gstreamer\1.0\x86_64\bin\gst-launch-1.0.exe -e -v udpsrc port=5000 !
application/x-rtp, payload=96 ! rtpjitterbuffer ! rtph264depay ! avdec_h264
! decodebin ! x264enc ! mp4mux ! filesink
location=C:\\Users\\Progettazione\\Desktop\\file.mp4

All the attempts I made to record and see in one command did not work

For example, I get the error:

WARNING: erroneous pipeline: could not link fpsdisplaysink0 to filesink0

How can I do? Thanks in advance.
