Hi Everyone; I'm trying to design real time video streamer.Firstly i tried it in my local system with my webcam.The senario is,I'm sending my webcam capture via udp at the same time i'm receiving this data from my local network.I could succeed to show my webcam capture but I couldn't overcome the latency and the video is not smooth.I wrote my command below,please advise me how can i handle these problems. Receiver gst-launch udpsrc buffer-size=16777216 port=1234 ! ffdemux_mpegts ! ffdec_mpeg2video ! autovideosink Sender gst-launch v4l2src ! video/x-raw-yuv,width=320,height=240,framerate=\(fraction\)30/1 ! ffenc_mpeg2video ! ffmux_mpegts ! udpsink host="10.0.0.217" port=1234 Faruk |
Why video is not smooth is because you are not forming rtp packets of encoded data and that's why some of the packets are getting lost or not reaching in proper order while transferring data from sender to receiver. Its would be better if you use rtp packetizer and depacketizer plugins at respective side.
So pipeline should be something like this,
Sender:
gst-launch v4l2src ! video/x-raw-yuv,width=320,height=240,framerate=\(fraction\)30/1 ! ffenc_mpeg2video ! rtpmp2tpay ! udpsink host="10.0.0.217" port=1234 Faruk
Receiver:
gst-launch udpsrc buffer-size=16777216 port=1234 ! rtpmp2tdepay ! ffdec_mpeg2video ! autovideosink
