how could i use gstd with python is there nat way to use with python about gstd-1.x

[fischer]

A python client binding was recently added - https://github.com/RidgeRun/gstd-1.x/tree/master/libgstc/pygstc. Looks like the documentation for using python is not yet in place - https://developer.ridgerun.com/wiki/index.php?title=GStreamer_Daemon. Hopefully you can see the pattern on how to create and control pipes and then transfer that knowledge to enable you to use the python GSTD client binding.

@DeveloperRachit you can find the PyGstc documentation here: https://developer.ridgerun.com/wiki/index.php?title=GStreamer_Daemon_-_Python_Client

We released GstD v0.9.0 yesterday, including this feature, so it is pretty new and the documentation is a work in progress. We would be happy to hear your feedback!

can i get example using pygstc with python

how to create pipeline by using pipeline_create these kind of example

i am getting that error when running my code because in element_set i set listen-to property

Hi @DeveloperRachit, we have a demo available that uses these Python bindings. It's based on interpipes + deepstream, you can check it here: https://developer.ridgerun.com/wiki/index.php?title=NVIDIA_GTC_2020:_How_to_build_a_multi-camera_Media_Server_for_AI_processing_on_Jetson

About the issue, it seems you're receiving a empty JSON (this is happening because an error generated when setting the listen-to property). Please check you're defining properly your pipelines. You can look at the demo provided above. Also if you can provide code it would be helpful to try to replicate and provide a more precise feedback.

Dear do you hve any kind of switching example between two source using gstd with but should be seamless when I would use live rtmp source

Hi @DeveloperRachit, the next Gstd Release v0.11 will improve the error handling for the python GSTD client.
