hi all,
i am able to link the decklinksrc to udpsink host 127.0.0.1 port 5004 .
using command :
gst-launch-0.10 decklinksrc mode=17 connection=composite ! videorate !
videoscale ! ffmpegcolorspace ! "video/x-raw-yuv, width=320, height=240,
framerate=15/1" ! tee ! queue ! ffmpegcolorspace ! vp8enc bitrate=256000
speed=2 max-latency=1 error-resilient=true ! rtpvp8pay ! udpsink
host=127.0.0.1 port=5004 sync=false -v
could you help me to get the gst launch screen on webpage i.e . to fetch
the video from udpsink 127.0.0.1 port 5004 and display the gst-launch on
the webpage .
regards,
satyam
