Title: Gapless Playback with UPNP and DLNA
Post by: MikeO on November 17, 2020, 04:39:22 am
I am struggling trialling a control app, mConnect, it seems not to provide gapless but it’s a control app why should it have an impact, it shouldn’t touch the signal? MC server to renderer by Ethernet

I have used Andrews tool to check my renderer, Cambridge Audio CXN, it returns gapless true. I have gapless set in options

Playing from MC controlled by JRemote I get gapless (dark side of the moon), likewise using StreamMagic the CA app I get gapless

Using mConnect I don’t ?

MConnect claims gapless by uPNP , the only difference I can see is DLNA v uPNP. They provide two gapless option switches neither makes any difference.

Correct me if I am wrong but doesn’t JRemote work with a protocol outside of uPNP/DLNA

The only reason I am considering this app is that in one app it gives me access to my local DLNA library and to Tidal in a direct stream to my hifi rather than having to AirPlay to the CXN wirelessly

Clearly if it doesn’t support gapless it’s a dead loss

Anybody got any ideas ? MConnect support suggest it is my renderer which it clearly isn’t

Try setting the MC server to no conversion.

What will that do ?

As you get Gapless when you play local files (in the MC Library) from MC to the CXN using MC as the DLNA Server and JRemote DLNA Controller, then do you also get Gapless if you simply replace JRemote with mConnect?

If Gapless does work in that situation, but doesn't work when you try to play Tidal to the CXN, then mConnect is probably having the same issue as when people try to play Tidal via the WDM Driver and MC to a DLNA Renderer; streams of unknown length can't be played to a DLNA Renderer.

But it may not be that straight forward.

By the way, the DLNA Controller is involved in sending the SetNextAVTransportURI, which is what enables Gapless playback to a DLNA Renderer.

If you are using mConnect as a source of Tidal content, then is is really acting as a Streamer, and DLNA Controller for the CXN DLNA Renderer. That is quite a different thing. I assume that Tidal will play locally on the device when using mConnect.

Also, JRemote uses a mixture of JRiver MCWS and uPNP/DLNA. When playing to a DLNA Renderer, it must use the DLNA protocol. Basically, it uses MCWS and the JRiver Access Key method to connect to a MC Library Server, and DLNA for just about everything else, I think. I could be wrong.

PS: I've only ever checked out mConnect Lite on Android, so don't know its full capabilities.

Thanks, comprehensive as ever

Tidal via mconnect works fine , I assume by DLNA as I am not using the iPad to stream

DLNA via JRemote runs fine, DLNA  via the CXN app works fine

I don’t think it’s my system, it’s the app, I was really just checking my facts

Between tracks I see the wait circle on the app, then the artwork changes, I suspect the app is too busy processing the artwork to move tracks, it not an iPad issue it’s a new spec iPad Pro. It must be the app. My old Mede8er had the same issue

It’s with their support team now

It takes two to tango: The renderer must support the gapless command. And the Control Point must send it.

Thanks Andrew , I think that’s the issue . I need to persuade mConnect of that

It looks like a $10 experiment gone wrong, c’est la vie

I’ll report back if they fix it. It was a nice option with my local MC library and Tidal in one app
