Video jumps a couple of seconds forward

[marceliano13]

Hello all

I built the following architecure:

App1 receives mpegts through SRT and sends it to App2 by SRT/UDP/RTP (whatever)
App2 receives mpegts, it decode and encodes it and then sends the encoded result to Oven by mpegts UDP or mpegts SRT.

I'm having some weird behavior that sometimes the video jumps like 3 seconds into the future (like going from 24/11/2025 13:01:00 to 13:01:07).

I see this logs but i don't know what i can do to prevent this.

It seems that everytime this logs pop up i have those jumps

I already tried stream directly from App1 to oven and i get the same behavior

[marceliano13]

Just an update i currently tested this workflow:

External source -> SRT -> App1 -> SRT -> Oven.

Even with this "simple" workflow i get the logs that i reported and the jumps in the video.

The pipeline for APP1 would be something like:

srtsrc ! queue ! tsparse ! tsdemux ignore-pcr=true ! h264parse config-interval=1 ! mpegtsmux ! srtsink

I already tested without the ignore-pcr and config-interval and saw no changes

My publisher settings:

<AppWorkerCount>8</AppWorkerCount>
<StreamWorkerCount>0</StreamWorkerCount>

My HLS settings:

<ChunkDuration>0.2</ChunkDuration>
<SegmentDuration>2</SegmentDuration>
<SegmentCount>4</SegmentCount>

"Failed to pop packet until 500 ms"
The log clearly states that no input signal was received for more than 500 ms. There may be a signal problem at the front end.

[marceliano13]

Front end? So this is a warning of the player that is pulling hls?
What i did was to update the ErrorToleranceDurationMs to 3000 ms in the POST create channel and now i don't have any issue.
I belive that error was making the channel go back to fallback mode and that would reproduce the video jumps.
