Picam gst-rtsp to vlc

[henryco]

i'm trying to receive a gst-rtsp stream from a raspberry Pi camera on vlc.

On Pi

raspivid -t 0 -w 800 -h 600 -fps 10 -b 4000000 -vf -n -o - | gst-launch-1.0 -v fdsrc ! h264parse ! gdppay ! tcpserversink host=127.0.0.1 port=5000

followed by

test-launch "( tcpclientsrc host=127.0.0.1 port=5000 ! gdpdepay ! rtph264pay name=pay0 pt=96 )"
gives message:
stream ready at rtsp: 127.0.0.1:8554 test

but on client PC, vlc is not able to show the video and thgere are no error messages

on the other hand with this more simple example
. test-readme

, vlc does show the simple video image
can someone help please ? is there somewhere a working (up to date) example with (GStreamer) gst-rtsp, and pi camera streaming

Hi!

This works( without rtsp though):

 

sudo modprobe bcm2835-v4l2

./src/http-launch 8080 \( v4l2src  device=/dev/video0 ! "video/x-h264, framerate=15/1, width=1280, height=720" ! queue ! h264parse ! mp4mux fragment-duration=10 faststart=true name=stream \)

In vlc open "http://192.168.1.6:8080”

I would recommend Jan's rpicamsrc element which does roughly the same
as raspivid, but you can use it directly in a GStreamer pipeline. That
way you can just use it in test-launch directly. It has the added
benefit of setting proper timestamps on the buffers.

You can find it here: https://github.com/thaytan/gst-rpicamsrc

thanks but eventually the stream should be received bu zoneminder (i first test with vlc because simpler) so i really need a rtsp stream, moreover this is for a webcam, not The Picam right ?

so i really need  raspivid ==> gst-rtsp ==> vlc (or zoneminder)

[Tonu Jaansoo]

Module bcm2835-v4l2 creates v4l source for picam. No need to mess with raspivid.

I tried it, and ... it works ! thank you ... i can hardly believe it after spending hours trying all sort of tutos on the web...
i use it inside test-readme and zoneminder receives the stream ...

Then I noticed that i have one second latency at ~ 5 fps and latency reduces importantly with higher fps : so probably a buffering effect. i'm wondering if i could modify the pipeline to do better with rtsp at low fps or if it's zoneminder which is fully responsible for the latency.
I know that with gstreamer pipeline alone i had negligible latencies in the past but it was not with the RTSP protocol ...

the line with the pipeline in the test-readme.c code is:

gst_rtsp_media_factory_set_launch (factory,
      "( rpicamsrc bitrate=10000000 ! video/x-h264,width=800,height=600,framerate=60/1,profile=high ! h264parse ! rtph264pay name=pay0 pt=96 )");

thank you again

[henryco]

hello,

really no feedback on the possibility to reduce latency (reduce buffer ?) in the pipeline of my previous post ?

thank you in advance
