HDHomeRun Apps slowly get behind playing live stream

[stalecheetos]

The HDHomerun app on PC and Google TV slowly get behind as time elapses.

For example, if I start a stream via VLC and another in the HDHomeRun app and they are perfectly in sync, after a few minutes the HDHomeRun will be 2-3 seconds behind.

A couple things I have noticed:
-VLC does not have this issue
-Plex does not have this issue (It is slightly delayed of course, but it remains the same throughout the life of the stream)
-HDHomeRun on Windows 10 has this issue
-HDHomeRun on Android (phone and chromecast with google TV) has this issue


It's almost like its playing a 30fps stream at 25 fps and slowly getting behind as time passes.

I tried searching the forum for this and couldn't find anything, is this a known issue?

I’ve posted about this before but can’t find it back.

I left the football game running for around an hour and twenty-five minutes and when I skipped forward, it went ahead nine seconds. This is on an Xbox.

Yeah, It's most obvious when you have something like a game on in multiple rooms and the xbox or chromecast using the hdhomerun app get behind compared to the vlc stream on pc.

This is by design - the HDHomeRun app will drop behind real time until it reaches 4 seconds behind, then it will maintain 4 seconds behind.

This approach provides fast channel change time and avoids buffering pauses.

Alright, I guess that makes sense. Thanks Nick!
It would be nice if we could choose to disable this. 4 seconds can be a lot of time when you are watching something like live sports.

I’m watching a hockey game tonight and there’s a 6 second gap between my Xbox which has been tuned for 30+ minutes and a just tuned-in iPhone.

This is why whenever I would try to watch the NFL with my radio broadcasters it would constantly go OOS and I was always trying to FF or pause to fix it. It was so frustrating to have to listen to the terrible announcers we got, because the Eagles sucked and not be able to listen to the home announcers. Thanks for the info.

Another hockey test tonight... watching on a wired Xbox for under 90 minutes and it was over seven seconds behind a just-tuned-in iPhone. Skipping ahead dropped the gap to two seconds. This long of a gap seems to be outside the intended buffer. I also feel as if there is some stuttering in the live feed on the Xbox, particularly noticeable in sports and more so on 720p sources. The LG app is much smoother looking, but with no transport buttons and the fact that not all cable channels display video on the LG TV, that’s not a better solution for me.

I have tested this some more too and it certainly goes past the 4 seconds @nickk mentioned previously. Over the span of a half of football it gets about 8 seconds behind

I'd like to know if this is related to the choppy display of 720p programming (particularly visible during sports) that I see or if that's a separate issue with the player in the Xbox. A game on a 1080i source (CBS, NBC) doesn't appear to have the same issues.
