Chromecast Picker showing duplicates

[tinskip 0]

I run about a half dozen Chromecast devices on my (switched) network.  One Ultra, three Audio, one built-in (Sony Bravia), and three Home.  Each and every one of these devices shows up twice in the Cast device picker.  And more often than not, picking a device does not work, sometimes even trying both "instances" of the same device.  Only quitting the Emby app, and restarting it will fix the connection issue, but not the duplicate device one.

 

This could be due to my running Android Pie (Pixel 2xl), but anyhow is something that ought to be addressed.  Anyone else experiencing this problem?  BTW, it does not occur with any other cast-enabled devices.

 

Thanks!

Hi there, why would you say this? It works just fine in my testing. We get the list of available cast devices from using Google's cast api. I have a plethora of Chromecast devices on my network for testing and haven't seen any problems.

I say this because I am a horrible person who is trying to make your life difficult.

 

Actually, it appears only actual Chromecast devices may be duplicated.

 

Are you testing with Android Pie? 

 

Please see screen attached.

Figured out the problem.  Somehow I wound up with two concurrent instances of the server running on my Mac.  I do not know how this could happen, since afaik you can only launch an app twice.  Killing both instances (via Activity Monitor), and re-launching, fixed the problems.  So not broken, sorry for the false alarm.

Oops.  Not figured out.  Issue re-occurred.  I have a theory: Currently my DHCP lease is set to 24 hours. Perhaps a different IP address is being assigned on lease renew, causing whatever component is caching the Cast device list to duplicate receivers.  Seems like a stretch to me, because the router ought to just renew the lease with the same IP address, but have upped the lease time to test the theory anyway.

 

QQ: Where does the mDNS scan for cast devices occur?  Server (would make some sense since it has the media, which can be pulled directly), or the client (most probably)?

 

Anything else I can do to debug the issue?

 

Thanks!

It is in the client.

Unstable HDCP leases was not the issue.  I'm still seeing the problem, and still do not know what triggers it.  I have attached three files:

 

- Before.png: Cast devices on Emby app after reboot.

- After.png: Cast devices on Emby app after things start to go South.

- Plex.png: Cast devices in Plex app (sorry).

 

In addition to the duplicate items, my Cast-enabled TV (XBR...) does not show up in Emby at all.

 

I am liking Emby more than Plex, other than this one snag, and I'd like to stick with it if possible.  Anything I can do to further debug this?

We'll look into it thanks.

Hey. I have this exact same issue - has there been a fix yet please?

[Luke 39003]

We're looking into this, thanks.

Just for information. Same problem on my chromecast interface. They are duplicate only on EMBY (not on DEEZER, ...).

Not duplicate on multiroom chromecast group.

 

Thanks in advance.

Can you please try this version and let me know how it compares:

Thanks !

Thanks for this - but it's no different for me unfortunately.

Like Rolhion, Chromecast groups appear correctly but each indivisible Chromecast appears twice. I've a tried a few other casting apps and all Chromecasts and groups appear correctly.

Cheers.

I'm having the same issue, It appears as soon as a chromecast device is a member of a chromecast group, it is seen double by the emby app. Since a short while it is possible to add a video chromecast to a chromecast group, as soon as I did this (for test) my video chromecast appeared twice in de chromecast picker.

[Luke 39003]

We're still looking into it, thanks.

I am also having this issue. All my chromecasts show up as duplicate entries. And 1 of the duplicates does not work for each device.

 

I've tried restarting emby and restarting all my chromecast devices.

[Luke 39003]

Apologies for the delay on this. It is on our list for review. Thanks guys.

Hi Luke, Maybe, I have the same issue reported in my topic https://emby.media/community/index.php?/topic/70588-some-smaller-issues-ive-found-with-emby-android/
I fugured out one specific situation when my chromecast device will be duplicated in the emby android app.

 

Maybe, this can help you finding the root cause?

[Luke 39003]

Thanks, we are looking into it.

[CChris 58]

sure, I will try it over the weekend

Sorry if somehow hijacking the thread but I also had the issue.

 

It seems resolved now when I just tested, but I can see all my Google Homes and also my Google Speaker Groups in the list. This isn't the case other streaming services so I believe they can be filtered?

 

Thanks

[CChris 58]

No issue for hijacking the thread
I have't got the time to test the app yet - and since I have had the issue on an older Device with an older Android version, I'm not sure, if this app could run on it.

I haven't setup a newer device for my streaming yet... something I should consider for this weekend...

[Luke 39003]

Thanks.

Hi @@CChris, Please let me know how the latest app update compares. Thanks.
