I have a pipeline that uses tsdemux to separate a transport stream file into its h264 and KLV elementary streams, process each, then mux the streams back into mpegts. The pipeline runs normally for a few seconds and successfully processes some buffers, then hangs.
My pipeline works properly when I let tsdemux ignore the KLV branch. However, when I include the KLV branch I see the following error at the start of my program before it processes some of the buffers and hangs.
(python3:455): GStreamer-CRITICAL **: 10:12:37.484: gst_segment_to_running_time: assertion 'segment->format == format' failed
Generally, my pipeline takes the shape of:
- What I have tried:
- Ran with ./tegrastats to ensure the hang is infact still processing (high CPU).
- Ran with GST_DEBUG=5 and saw the following repeatedly printed out:

- Only demux one of the streams (ignore/drop the other)
a. Run video/x-h264 branch and let tsdemux ignore klv, the pipeline worked
b. Run meta/x-klv branch and let tsdemux ignore video, this does not work and the same segment error is displayed. I suspect there is some formatting issue with my KLV branch.
Please let me know what you think, I am happy to try any suggestions. Thank you!
