gstreamer send and receive h264 rtp stream

gs.sh

# linux send h264 rtp stream:
gst-launch-1.0 -v ximagesrc ! video/x-raw,framerate=20/1 ! videoscale ! videoconvert ! x264enc tune=zerolatency bitrate=500 speed-preset=superfast ! rtph264pay ! udpsink host=127.0.0.1 port=5000

# Macos send h264 rtp stream:
gst-launch-1.0 -v avfvideosrc capture-screen=true ! video/x-raw,framerate=20/1 ! videoscale ! videoconvert ! x264enc tune=zerolatency bitrate=500 speed-preset=superfast ! rtph264pay ! udpsink host=127.0.0.1 port=5000

# receive h264 rtp stream:
gst-launch-1.0 -v udpsrc port=5000 caps = "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ! rtph264depay ! decodebin ! videoconvert ! autovideosink

sdp file for playing in vlc:
c=IN IP4 127.0.0.1
m=video 5000 RTP/AVP 96
a=rtpmap:96 H264/90000

This is rough and may be wrong: it worked but video was off-looking.

Also to generate a stream with a test video instead of a screen capture in osx do:
gst-launch-1.0 -v videotestsrc ! video/x-raw,framerate=20/1 ! videoscale ! videoconvert ! x264enc tune=zerolatency bitrate=500 speed-preset=superfast ! rtph264pay ! udpsink host=127.0.0.1 port=5000

Could you maybe give an example over tcp?

You generate a video appling videobalance saturation=0 "greyscale"
gst-launch-1.0 videotestsrc ! videobalance saturation=0 ! x264enc ! video/x-h264, stream-format=byte-stream ! rtph264pay ! udpsink host=127.0.0.1 port=5000

Consume it :)
gst-launch-1.0 udpsrc port=5000 ! application/x-rtp, encoding-name=H264, payload=96 ! rtph264depay ! h264parse ! avdec_h264 ! autovideosink

If you need to stream the video to another computer you need to change the host ip and it was what i was doing it wrongly!

The host is the machine tha will recive the stream and not where the place when the video is hosted 🐙 it's tooks me a lot of time to overlap it!

gst-launch-1.0 videotestsrc ! videobalance saturation=0 ! x264enc ! video/x-h264, stream-format=byte-stream ! rtph264pay ! udpsink host=SERVER_THAR_WILL_RECIVE_THE_VIDEO port=5000

sudo -E gst-launch-1.0 udpsrc port=5000 ! application/x-rtp, encoding-name=H264, payload=96 ! rtph264depay ! h264parse ! avdec_h264 ! autovideosink

Hello All,

I need your help. On my computer I am receiving stream as UDPSRC on some port(port 5004) . I need to forward this from a different port to an end point that receives rstp streams. I am using the following:

udpsrc uri=udp://localhost:5004 ! application/x-rtp, encoding-name=H264, payload=96 ! rtph264depay ! h264parse ! avdec_h264 ! rtspclientsink location=rtsp://localhsot:5006/test

I even tried this:

udpsrc uri=udp://localhost:5004 ! rtspclientsink location=rtsp://localhsot:5006/test and didn't work.

But I cannot get it working. Anyone has any idea? what I am doing wrong. I am new to streaming. I am not sure if all these pipe are necessary or not. I would greatly appreciate your help.

I have this and works fine but I don't want to create .m3u8 files
udpsrc uri=udp://127.0.0.1:5004 ! application/x-rtp, payload=127 ! rtph264depay ! mpegtsmux ! hlssink max-files=10 playlist-root=http://127.0.0.1:8888/ location=./hlssink%05d.ts playlist-location=./wedpalylist.m3u8 "

Thanks,
Farshid

BTW, I am getting connection refused message. I hope this helps.

Is there any plugin can automatically generate sdp file?

Hi guys I need to stream h264 streams from a udpsource on omxh264dec and sink it to wayland ... can someone please help

Follow these steps to generate a sdp source
a) gstreamer source stream append a -v as follows

gst-launch-1.0 v4l2src device=/dev/video0  do-timestamp=true !
 video/x-raw,width=1280, height=800,framerate='(fraction)'20/1 ! autovideoconver
t  ! omxh264videoenc  !queue ! h264parse  config-interval=1 ! rtph264pay pt=96 !
  udpsink host=192.168.2.158 port=5000 sync=false -v

b) This will give verbose output like one below

debug  : cedarc <BitStreamCreate:102>: BitStreamCreate OK
/GstPipeline:pipeline0/GstH264Parse:h264parse0.GstPad:src: caps = video/x-h264, stream-format=(string)avc, alignment=(string)au, width=(int)1280, height=(int)800, pixel-aspect-ratio=(fraction)1/1, framerate=(fraction)20/1, interlace-mode=(string)progressive, colorimetry=(string)bt709, chroma-format=(strin2

/GstPipeline:pipeline0/GstRtpH264Pay:rtph264pay0.GstPad:sink: caps = video/x-h264, stream-format=(string)avc, alignment=(string)au, width=(int)1280, height=(int)800, pixel-aspect-ratio=(fraction)1/1, framerate=(fraction)20/1, interlace-mode=(string)progressive, colorimetry=(string)bt709, chroma-format=(st2
/GstPipeline:pipeline0/GstRtpH264Pay:rtph264pay0: timestamp = 3016666383

c) Use the information above to make your sdp file.
Example sdp file from above is

v=0
o=IP4 192.168.2.62
i=test
c=IN IP4 192.168.2.62
s=ESP H264 STREAM
m=video 5000 RTP/AVP 96
a=rtpmap:96 H264/90000
a=fmtp:96 media=video; clock-rate=90000; encoding-name=H264; sprop-parameter-sets=Z00AIOVAKAMogA\=\=\,aO4xEg\=\=

d) Note that in the SDP file the IP address is that of the server. In the server gstreamer code, the IP address is that of the client

can anyone help me to generate rtp stream using decklink video source ?
