i don't understand above error when try to get sdp file by running get_sdp.py pls help me asap!!

[pkeroulas]

Do you have a response for this command? curl http://[your Embrionix IP here]/emsfp/node/v1/sdp/

[boyexpert]

I did not run that command individually. But i got some errors when running get_sdp.py

[pkeroulas]

1. can you ping that device?
2. can you explore the device in your browser?

[boyexpert]

I'm running to connect to NIC port on my own PC

From the script description: get_sdp.py - helper script to fetch SDP file from Embrionix sender so it uses Embrionix (now Riedel) API. If your PC is serving an NMOS node, please see ./nmos/get_sdp.sh.

[boyexpert]

Embrionix (now Riedel) API may not be installed on my PC can u help me install it ? (by a link)

[pkeroulas]

It's going to be hard: https://www.riedel.net/index.php?id=629 What are you trying to achieve? Do you have any ST 2110 source?

[boyexpert]

i'm trying to use transcoder to convert st2110 source to output (h264) and monitor it on screen it'll work like gstreamer tool

[boyexpert]

By the way, i got some responses when running /nmos/get_sdp.py

[pkeroulas]

ffmpeg takes an SDP as input, right. But you won't get any SDP from your PC. Take that sample, strip the audio (225.0.1.16) and the ancillary (225.17.0.16), and modify the video (225.164.5.190) with the network and video format corresponding to the output of your gstreamer process.

i tried to get sdp from another source but it got the same error i have to generate a sdp file from my st2110 source by running get_sdp.py or another to input a new file by coding somewhen i can't edit file manually

[pkeroulas]

Hi, if your source is a software running on a regular PC, you won't magically get a SDP from there. You'd rather have to craft the SDP from the example above or here

[boyexpert]

so, i'll try it. thank for your support!
