I've updated Minimstreamer and made an .m3u playlist containing your BBC URLs above. These show in my Naim control app, eg as [R3] BBC Radio 3, but won't play on my NDS. Is there something else I should be doing?

It seems that Naim streamers can't play ADTS AAC streams served by MinimServer. This might be caused by a MIME type mismatch but I can't find any information on this.

The stream will play if you transcode it to L16. To do this, add the 'aac' stream type to the playlist entry, for example:

#EXTINF:-1,[*R3;aac] BBC Radio 3
http://a.files.bbci.co.uk/media/live/manifesto/audio/simulcast/hls/uk/sbr_high/ak/bbc_radio_three.m3u8

and add the following to the stream.transcode property:

aac:L16

After making these changes, do a MinimServer rescan and clear the Naim app's UPnP cache.

Thank you Simon.
It works!

May I share this on the Naim forum?

I tried all of this and it isn't working for me on my Naim Unitiqute 2. Did you mean clear the app's image cache Simon? Also, do I just add the .m3u file to my Nas drive? It is showing as a playlist but nothing happens when I select a station...

Hope you don't mind me replying.
The clear UPnP cache is rather hidden in the Naim app menu.

Simon,

My Pioneer N-50 & Denon DNP-F109 streamers have a similar problem with the ADTS AAC streams served by MinimServer over UPnP.

Both devices when used as DNPs don't even appear to react when the AAC stream is selected for immediate playback, with not even an error is reported. They remain on the track selection screen within the playlist, rather than move on to the now playing screen.

For both streamers, when used as DMRs with the BubbleUPnP control point, the DMC's UPnP Mime-type check has to be switched off, otherwise it immediately reports a "track is not playable: no compatible decoder found (try disabling the Mime-type check..." error when the AAC stream is selected to play.
With the controller's UPnP Mime-type check disabled, this time after a few seconds delay it reports an "illegal MIME-type(code 714)" error on playback, for both devices.
Interestingly, both streamers remain on standby with the Mime-type check enabled and come out of standby on play with it disabled. This would seem to imply that both control point and streamer are indepentally reporting a similar sort of error.

Could the issue be something as simple as the control point and/or streamers checking to see if the 'file's' extension matches the Mime-type and failing?
Given that UPnP/DLNA streaming is normally used for physical files, rather than network streams, it's possible that this may be a common check done by UPnP devices (maybe even more likely dictated by DLNA). I've noticed that you kept the original stream's 'file extension' as .m3u8 in MinimServer's URL for it. Could a simple name change to the URL by adding a '.aac' suffix, sort the problem out?

Incidentally, both the Pioneer & Denon streamers use vTuner. Using MinimServer's URL for the BBC stream as an added station in their vTuner accounts results in the radio station streaming properly on both devices! Sort of backs up the above theory, since network stream URLs don't even have to have a file suffix, making the actual file type vs file name extension check inapplicable for the devices' internet radio function.

Many thanks RK, I have tried that now too and still nothing! I guess I will have to see if Naim pull their fingers out and get it sorted...just another thing in the long list of moans about the Naim app since they "updated" it!

Here are the steps to get this working on Naim:

1) Make sure you are running MinimServer 0.8.3 and MinimStreamer 0.5.2

2) Add the playlist to your library and make sure the URLs are correct. Here is a small sample playlist for testing purposes (note the 'aac' specification in the stream type):

Code:

#EXTM3U
#EXTINF:-1,[*R3;aac] BBC Radio 3
http://a.files.bbci.co.uk/media/live/manifesto/audio/simulcast/hls/uk/sbr_high/ak/bbc_radio_three.m3u8

3) Make sure ffmpeg or avconv is installed

4) In the stream.transcode property, add aac:L16

5) From the minim icon, select Rescan

6) In the Naim app, clear the UPnP cache

7) In the Naim app, browse to the playlist entry and play the radio stream

Please try adding an 'aac' stream type to the playlist entry (see my previous post for an example). This adds a .aac extension to the stream URL and also adds audio/aac as the MIME type in the protocolInfo information that the server sends to the control point.

Hi Simon
I never installed ffmpeg or avconv but your fix works.
How would it have got there? Would it have been installed on the Synology NAS with another package?

Synology DSM includes a free ffmpeg.

Many thanks Simon for your explanation, I have tried all these steps as specified and unfortunately it does nothing when I click on the playlist.

And Marantz being a flavour of Denon it works on my M-CR603 streamer as well. Sadly not on my Musical Fidelity player. It's not impossible that the length of the URL could be an issue, since it does play from a local playlist containing the new BBC URLs.
