Emby Web constantly "losing connection" when Chromecasting media.

[Mr_Scumbag 8]

This seems to happen every few versions of Emby server, which is why I usually hold off on updating for many months once this issue stops after upgrading to a "good" version. It's very frustrating and has been occurring for years.

I'm using the latest version of Chrome and Emby server.

After Chromecasting, the media will continue playing as normal, but anywhere between a few minutes to a hour after playing the media, the Web app will stop communicating with the Chromecast, meaning that the status bar will stop moving and showing how far into the media it is, and all controls (pause, next, previous, etc) will stop responding, but the media continues to play on the Chromecast. The only way to resolve this is to disconnect and reconnect to the Chromecast or (sometimes) to refresh the Emby Web page, although about 50% of the time, refreshing the page will immediately disconnect the Chromecast, stopping media.

Importantly, I also use the web app with a different server running an older version, and this issue very rarely ever occurs, so it certainly seems to be related to the version. Why it's a much bigger issue in some versions than others is worth investigating, I think.

I'm interested in hearing from others who Chromecast from Emby Web in Chrome. I imagine it's not a particularly common setup, but are there others experiencing this issue?

Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks!

 

[Mr_Scumbag 8]

Thanks for your response and sorry for my delayed reply. I had to wait for the issue to occur again in a time window where I was easily able to find the right part of the log.

The issue described above has just occurred again, although slightly differently in that instead of the stream still playing on the TV, it has completely frozen and the controls on the PC are not working either. This happened about 3min and 50 seconds into playing a movie.

The log is small enough to post here:

@Mr_Scumbag can you please attach the complete emby server log (and the ffmpeg log if there was one)? Thanks !

[Mr_Scumbag 8]

I have attached the requested log files. As the issue occurred at around 10:30am, I'm not sure the FFMPEG log will contain anything useful, though.

[Mr_Scumbag 8]

@Luke Is there any indication of the cause of this issue in the logs I provided?

[Luke 37060]

Hi, I don't see anything obvious. Have you updated to Emby Server 4.7.6? Are you still running into this?

[Mr_Scumbag 8]

@Luke I have updated and it is still occurring. It seems to be less frequent, but it's hard to tell without more time with the new version.

[Mr_Scumbag 8]

Update: Seems to be happening more frequently now. I haven't been able to watch anything (45 min episodes) all the way through without it occurring since I updated.

[Luke 37060]

Are you still seeing this?

[Mr_Scumbag 8]

Yes, and other issues. Sometimes the video just stops altogether on the TV as well as the webapp. The only way to recover it is to un-chromecast then re-chromecast, but now sometimes I'm not even able to un-chromecast Emby which is a new wrinkle I've not encountered for any app before. The only way to fix this when it happens it to chromecast something else to the TV. Othertimes, the stream will start pausing or stuttering for no obvious reason. Disk I/O is fine, wireless is fine, network traffic is fine. un-chromecasting, re-chromecasting and then resuming the video will fix the issue. Sometimes for the remainder of the video, sometimes only for 10-20 minutes. It's very random.

I've decided to switch to Plex until the next major Emby update cause it's becoming too much of a hassle to babysit.

Hi, did you see this? https://www.pcworld.com/article/871581/change-your-plex-password-right-now.html

Anyway can you try this again?

[Mr_Scumbag 8]

Tried it again. It's worse than ever. Completely unusable while Chromecasting.

[Luke 37060]

@Mr_Scumbag are you still running into this?

[Mr_Scumbag 8]

It seems to be working properly now. That has happened before, though. Usually it lasts for a while until the issue starts occurring again after a new update.

 

I guess all I can do is keep using it and see what happens.

[Luke 37060]

Thanks for the feedback.

[Mr_Scumbag 8]

Happening again. Constantly. Plex is working without a hitch.
