RTMP to WebRTC issue after enabling ABR #4668

Open yashtandon113 opened 1 year ago

yashtandon113 commented 1 year ago

Short description

When the ABR on the server is enabled, the WebRTC stream does not work after the stream is published from the specific encoder (Live Shell X). Although the stream works fine without ABR.

Environment

Steps to reproduce

  1. Enable the ABR on the server
  2. Publish an RTMP stream from Live Shell encoder.
  3. Play the WebRTC stream

Expected behavior

Stream should work fine without any issue.

Actual behavior

The stream did not always work. After restarting the server, the stream started to work on a round-robin basis. The stream did not work on a GPU server, even after restarting the AMS.

When we print packet type, the calculated dts and the packet time stamp, we got these for working and non-working cases:
