Non-monotonous DTS in output stream - live detection

Channels DVR Server Troubleshooting
#1

I'm getting some really odd log output and playback behavior. Watching live is fine but trying to watch the recording shows the below log and all I see is the lower thirds timeline bar with a spinning asterisk. Some of the commercial markers are displayed. I've turned off the live detection but the job is still running.

Where was this recorded from? It sounds like the sort of thing that would happen with bad reception.

I tried doing another recording via OTA and I'm still getting errors like:

2022/09/25 20:37:51.350718 New diagnostic log submitted under bf8634f2-edad-4c78-ae40-f7f813081f87

I've tried disabling the HEVC transcoding Experimental flag and watching from the web interface but that doesn't seem to correct things.

#5

Is there a place to check and see if a station is doing work on their transmitter stations? KABC-DT is throwing a lot of errors (as you predicted) which is very strange.

What is even odder is that the previous recording was from a TVE feed which shouldn't have a garbage feed?

The HEVC Experimental flag does not impact watching from the web interface.

The sigerr=33% shows that 33% of the time of recording that channel there were signal problems. Your reception is really bad with this station and there isn't much we can do about it — you'll have to adjust your antenna to fix it.
