[sravich1]

Hi all,
I installed all the required rpos and trying to run the rpos.js

getting below error and not able to get RTSP or ONVIF

ffmpeg - starting
ffmpeg - finished
ffmpeg exec error: Error: Command failed: ffmpeg -fflags nobuffer -probesize 256 -rtsp_transport tcp -i rtsp://127.0.0.1:8554/path_to_video_tream -vframes 1 -r 1 -s 640x360 -y /dev/shm/snapshot.jpg

Hi,
ONVIF not working ..mediamtx working..Let me know any change in the process

Here is the following way in which I downloaded and started with the rpos

download from
git clone https://github.com/BreeeZe/rpos.git
cd rpos
npm install

do npx gulp
get the rpos.js
now use rposConfig.sample-picam.json to copy and create rposConfig.json..change the IP address here
"IpAddress" : "10.35.62.108",
4 "ServicePort" : 8081,
5 "Username" : "admin",
6 "Password" : "admin",
7 "CameraType" : "picam",
8 "RTSPAddress" : "", "//":"Normally left blank. Used to set RTSP Server Address",
9 "RTSPPort" : 8554,
10 "RTSPName" : "h264",
11 "MulticastEnabled" : false,
12 "RTSPMulticastName" : "h264m",
13 "MulticastAddress" : "224.0.0.1",
14 "MulticastPort" : "10001",
15 "RTSPServer" : 3, "RtspServerComment" : "## Select RTSP Server > 1:RPOS RTSP Server 2:V4L2 RTSP Server by mpromonet (auto selected if MulticastEnabled=true)",
I have used RTSPserver 3 here...with1 getting error

getting the ffmpeg error
ffmpeg exec error: Error: Command failed: ffmpeg -fflags nobuffer -probesize 256 -rtsp_transport tcp -i rtsp://127.0.0.1:8554/h264 -vframes 1 -r 1 -s 640x360 -y /dev/shm/snapshot.jpg

mainly ffmpeg Error

[RogerHardiman]

The problem is this line in your configuration
"RTSPAddress" : "hostname_of_remote_rtsp_server", "//":"Normally left blank. Used to set RTSP Server Address",

ffmpeg is used to connect to the RTSP server, grab 1 frame of video and then make a JPEG image. It us used by the ONVIF GetSnapshotURI.

You have told RPOS that your RTSP server is at rtsp://hostname_of_remote_rtsp_server
I doubt you have a computer on your network called "hostname_of_remote_rtsp_server.local"

You started with the Proxy config example where you have to specify a remote RTSP server.
If you are wanting to use the RTSP sever inside your Pi, you'll set RTSPAddress to ""
