@rusty gapless is a feature end users absolutely demand in 2021, and they're not really interested in technicalities. If your software/app vendor isn't capable of providing that, you've got a big problem with your streaming products, and might want to consider an alternative vendor for that part.
Please read my post again about gapless.
The issue is the streaming client which is designed to handle Spotify etc is not designed to handle DLNA server in gapless mode (not yet, working on that). Other products that people used as examples are Linux based (which they implemented Spotify support through API on the server side).
Anyway, all these explanation is beyond the understanding of most users. Our supplier also supplies Harmon and many other big brands.
They are probably the only one left that can make long term commitment on the platform and provide a suite of modules and app.
Take a look at Qualcomm AllPlay. It used to be one of the supplier, and Qualcomm reportedly spent more than
$100M on audio streaming and eventually shut down the project. Many large companies that used AllPlay also suffered huge losses. And you think there are other supplier that can meet our long term requirement? There is none. Sure, if we want to develop a gapless DLNA streamer, that's very easy. That's not our plan. We need a supplier with very deep pocket, with millions of users, with the ability to provide multiple chipsets that work with the app, with system integrators that can work with us to design various form factors and streamers. And also scale from low cost module to high performance ones.
We know all the suppliers in the business
