webrtcbin blocks indefinitely when set back to a state of NULL if added dynamically to PLAYING Pipeline (webrtc plugin bug?)

Open rjhowell44 opened this issue 3 years ago • 0 comments

There are two uses cases defined on the WebSocket Server API Reference page with two corresponding python examples:

  1. 1file_webrtc_connect_post_play.py
  2. 1file_webrtc_connect_pre_play.py

Use case 2. -- where the WebRTC Sink is added to the Pipeline prior to playing -- works without issue. Use case 1. -- where the WebRTC Sink is dynamically added to a playing pipeline with the main-loop running -- will lead to a lockup when the wbrtcbin gst-plugin is set back to a NULL state.

After considerable debugging and some research, the issue is believed to be in the GStreamer webrtcbin plugin. More information to follow.
