testing the Audio-Video sync of a USB WEBCAM using simple Gstreamer AV streaming scripts
Here are the Gstreamer scripts for the Linux Gstreamer Transmitter:
STREAM VIDEO TO WINDOWS 10 LAPTOP from USB WEBCAM
gst-launch-1.0 -v v4l2src device=/dev/video2 ! "image/jpeg,width=768,height=480,framerate=25/1" ! rtpjpegpay ! udpsink host=192.168.1.142 port=5006
STREAM AUDIO TO WINDOWS 10 LAPTOP from USB webcam MIC
gst-launch-1.0 -v alsasrc device=hw:4 ! "audio/x-raw,rate=48000,channels=1" ! audioconvert ! opusenc bitrate=128000 frame-size=5 ! rtpopuspay ! udpsink host=192.168.1.142 port=6003
Here are the RECEIVER Gstreamer scripts used on Windows 10 pc
RECEIVE USB WEBCAM VIDEO
C:\gstreamer\1.0\x86_64\bin
gst-launch-1.0.exe -e -v udpsrc port=5006 ! application/x-rtp, encoding-name=JPEG,payload=26 ! queue ! rtpjpegdepay ! jpegparse ! jpegdec ! queue ! autovideosink
RECEIVE USB WEBCAM AUDIO
C:\gstreamer\1.0\x86_64\bin
gst-launch-1.0.exe -v udpsrc port=6003 do-timestamp=true ! "application/x-rtp, media=(string)audio, clock-rate=(int)48000, encoding-name=(string)OPUS, sprop-maxcapturerate=(string)48000, sprop-stereo=(string)0, payload=(int)96, encoding-params=(string)2, ssrc=(uint)3863443941, timestamp-offset=(uint)1230448530, seqnum-offset=(uint)12158" ! rtpjitterbuffer latency=60 ! rtpopusdepay ! opusdec plc=true ! audioconvert ! wasapisink buffer-time=30000
