Is there a way to manually EOS in python object?

[erfansafaie]

Hello @dusty-nv.
I have two questions:
1- How we can send EOS event or closing the stream manually in python? Or any object in c++? (without OpenGl window)

2- Is OpenGL window run in main thread? I have a Qt app and I use videoSource and videoOutput objects. When I clicked start recording video in my app it will start recording in other thread. Finally, I close OpenGL window, recorded video is saved but OpenGL window not close and freeze! It will close when I close my app. So I think showing window is running on main thread?!

Hi @erfansafaie, the OpenGL window runs in the same thread as from where you call it from - you can find the source here:

Also to close videoOutput interface, call videoOutput->Close() - for GStreamer pipelines, this will gracefully shut them down and send EOS (so the video files/ect should be seekable)

I appreciate your response and help.
Is it work in python the same(videoOutput.Close())? I read the binding codes and Close function, I think it's not working like destructor in C++.
