Hello,

If you want to publish an RTSP stream you might want to use the RTSP server
from gst-rtsp-server repository
https://gitlab.freedesktop.org/gstreamer/gst-rtsp-server.

From there you can get inspiration or run the test application 'test-launch'
you can easily build with gst-build:

./build/subprojects/gst-rtsp-server/examples/test-launch "( videotestsrc !
videomixer name=comp sink_0::xpos=0 sink_0::ypos=0  sink_0::alpha=0
sink_1::xpos=0 sink_1::ypos=0 sink_2::xpos=320 sink_2::ypos=0 sink_3::xpos=0
sink_3::ypos=240 sink_4::xpos=320 sink_4::ypos=240 ! videoconvert !
video/x-raw,format=NV12 ! x264enc ! rtph264pay name=pay0 pt=96 videotestsrc
! comp.sink_1  videotestsrc ! comp.sink_2 videotestsrc ! comp.sink_3
videotestsrc ! comp.sink_4 )"

And then

gst-launch-1.0 uridecodebin uri=rtsp://127.0.0.1:8554/test ! autovideosink

Than you can replace videotestsrc by your rtsp stream.

Regards.

THX for the reply,

the server service is running in this time with the rtsp server.
I have an testvideo fron the testserver source, linke your sample.

But how looks like the pipe command to combine the quad command and the
server command ?

thx for an possible answer

Hi,

You can give a try to:
       
./server & sleep 1 && ./client && killall server works like a charm

or

/build/subprojects/gst-rtsp-server/examples/test-launch "( videotestsrc !
videomixer name=comp sink_0::xpos=0 sink_0::ypos=0  sink_0::alpha=0
sink_1::xpos=0 sink_1::ypos=0 sink_2::xpos=320 sink_2::ypos=0 sink_3::xpos=0
sink_3::ypos=240 sink_4::xpos=320 sink_4::ypos=240 ! videoconvert !
video/x-raw,format=NV12 ! x264enc ! rtph264pay name=pay0 pt=96 videotestsrc
! comp.sink_1  videotestsrc ! comp.sink_2 videotestsrc ! comp.sink_3
videotestsrc ! comp.sink_4 )" & sleep 1 && gst-launch-1.0 uridecodebin
uri=rtsp://127.0.0.1:8554/test ! autovideosink && killall test-launch

Regards.

Changing videotestsrc to an local rtsp stream from an ip camera.

./test-launch "( videotestsrc !
videomixer name=comp
sink_0::xpos=0 sink_0::ypos=0  sink_0::alpha=0
sink_1::xpos=0 sink_1::ypos=0
sink_2::xpos=320 sink_2::ypos=0
sink_3::xpos=0 sink_3::ypos=240
sink_4::xpos=320 sink_4::ypos=240


! videoconvert ! video/x-raw,format=NV12 ! x264enc ! rtph264pay name=pay0
pt=96
uridecodebin uri=rtsp://user:pass@10.0.01/stream1 ! comp.sink_1  
videotestsrc ! comp.sink_2
videotestsrc ! comp.sink_3
videotestsrc ! comp.sink_4 )
" & sleep 1 && gst-launch-1.0 uridecodebin uri=rtsp://127.0.0.1:8554/test !
autovideosink && killall test-launch

why didnt it run, it shows only the the 4 testvideo in a mosaic, where is my
error, to change one of them to my live videostream?

thx

Always look at the log messages spit out by setting the
GST_DEBUG=3 env variable when something fails and you will find the
answer there most of the time.

With gst-launch-1.0 you must be extra-careful to continuation
separators, at the end of each line, while with test-launch you might
not have to because the argument is a single string.

Also, if this is meant to be a local test, you probably want to use
"decodebin" with no properties instead of the very last uridecodebin
which is meant for the case when you have an actual server.
