Buffering then failing

Having trouble with some TVE channels. It will load play for a few seconds then buffer and not play. Doesn't seem to be every channels though. Ones I have noticed the most is espn and freeform.

You are not alone John. Quite a few channels are not playing properly. I'd guess there is an internet issue between us and them.

For me it's TVE Verizon FIOS Queens NYC

If it happens often enough you could narrow it down.

  1. Try playing the trouble TV channel from the DVR web UI on a PC/Mac on your local network.
  2. Also try logging into the network live feed in a web browser and playing it.

If both have the same issue, it's the TV network feed.
If neither of the above have an issue, it's the client device or network path from the DVR server to it.
If #1 has an issue and #2 doesn't, it's probably Channels DVR.

Hmm, I will have to do some investigating. It is not always consistent. This morning one channel buffered a lot or would not play, came back a few min later and no problems. I have tired playing through the web player with same issue but not on network live feed. I am signed in though dish but have friends YouTube tv as well and they always play fine there.

1. Try playing the trouble TV channel from the DVR web UI on a PC/Mac on your local network.

This is how I tested and it was a problem. No problem today. A recording from this feed had the same symptom yesterday, now that is strange...

2. Also try logging into the network live feed in a web browser and playing it.

If it happens again, I'll try this. I'm a retired network director/engineer. It's not my network and I have no other issues related to the internet.

Having multiple people with the same issue and then having it go away without an update to channels makes me believe it had something to do with the source, or the path to the source.

Was having trouble with ESPN playing. Attempted the web browser player and it was performing the same with buffering a lot or not playing at all. Able to play through the YouTube tv app and on ESPN.com with no problems. It seems to be a channels issue.

Any errors in the DVR web ui logs at the time of the issue?

I forget what time I was playing at but having the same issue right now. You're the logs when I try to start ESPN again.

I see there is transcoding happening in the logs, are all these attempts from the web browser? Do you have any full clients like iOS/android you can try to see if they also have issues?

Some of those are likely me testing it out on my phone Android as well. I have an iPad I haven't really seen If it happens at the same time on there. I'll have to do some testing. The little bit I've been using it recently. It's buffered a lot but eventually played. But on YouTube TV app I get almost no buffering.

Apples and oranges. The streams are coming from entirely different sources.

I could not get it to play on iPad at all for this channel. The logs are from the web player, it would not play either.

What device are you running the server software on? Does it have an internet connection? The logs indicate it’s having trouble connecting to the external streams.

Nvidia shield hardwired. Has internet connection it is my main steamer on living room tv.

Odd. I’m assuming you’ve already tried rebooting it and the issue remains?

I have. I rebooted the whole network. The strange thing is it isn't always consistent. Sometimes it plays without a problem, sometimes it plays for just a few seconds and then buffers and won't play again, and then in this case won't play at all. And it's not all channels. This one seems to be the biggest issue though.

Try the latest prerelease

I tried playing these from my Google Chromecast, one in the basement and one upstairs. One of them is hardwired and the other is not. Not what my server is running on which is the shield. It buffered played for a few seconds and then would buffer and not play again.
