Glitchy playback on unique time-shifting application

[Nathan_Kordyjaka]

I’m running into a lot of glitchy and choppy playback on some timeshifted streams. I’m hoping someone might have some ideas on what to look for or try here.

We’re running a 3xtimezone timeshift server plus live.

Workflow is as follows:

Application 1 (“ingest”) takes the rtmp feed in, transcodes a 360p and a 720p passthrough, and sends them to the CDN for a realtime stream, while also sending the 720p passthrough to Application 2 (ironically currently named “live”).

Application 2 takes that stream in, and timeshifts a 1 hour, 1xhour and 3xhour delayed signal all in 360p and 720p passthrough, then off to the CDN.

On playback, the realtime feeds from Application 1 is playing back flawlessly.

Playback from the delayed feeds (both the transrated 360p and the passthrough 720p) are glitchy, choppy, the audio skips, the video skips. Seems to be about every 4-6 seconds or so.

Any help with what to look at would be amazingly helpful. Thank you!
