You can also inspect [`Format.roleFlags`](https://developer.android.com/reference/androidx/media3/common/Format#roleFlags()) for some of those parameters you've listed. I think my answer above resolves your question - possibly combined with being able to [customize track names...

I suspect the difference you're seeing between 2.16.1 and 2.18.2 is due to HLS chunkless preparation being [enabled by default in 2.17.0](https://github.com/google/ExoPlayer/blob/release-v2/RELEASENOTES.md#2170-2022-02-24). You can enable it manually in 2.16.1 to...

Ah I hadn't spotted in your original code snippet that `controllerFuture` is not locally-scoped and, if there are multiple threads involved, could potentially be re-assigned in between the future completing...

Thanks for the update. I spent a bit of time looking at the session demo app's usage of `ListenableFuture`. I prototyped a change that switched it to `Futureas.addCallback`, but actually...

Please try and play **your** RTMP stream in the demo app, using one of the approaches described here: https://developer.android.com/media/media3/exoplayer/demo-application#playing-your-own-content

Did you build the demo app 'with decoder extensions'? It's a poorly named gradle flavour in this case, since RTMP isn't a decoder, but it is used to control whether...
