BBC R3 Lossless Stream

[DavidHB]

Thank you very much for the instructions, which I was able to follow without difficulty.

I mentioned in my PM that I was having problems with transcoded radio streams playing to my Linn ADSM/1. Because "flac:wav24" was already set on my system, I left that setting in place. The player at first attempted but failed to play the lossless stream, and the following error message sequence appeared in the MinimServer log:

Error: java.io.IOException: Stream closed at offset 0 in file null (length 0)
MPEG-DASH: error reading initial segment
Error reading DASH stream: org.jminim.LogErrorException: MPEG-DASH: error reading initial segment
org.jminim.LogErrorException: MPEG-DASH: error reading initial segment
at org.jminim.core.LogImpl.error(LogImpl.java:219)
at com.minimstreamer.NetworkSource$DASHReaderThread.playStream(NetworkSource.java:1​915)
at com.minimstreamer.NetworkSource$ReaderThread.run(NetworkSource.java:870)

If I try to play the FLAC stream without transcoding, the DSM simply does not recognise the stream; no error message appears in the MinimServer log. This consistent with the advice from Linn in this thread on their forum that

"MPEG-DASH format is not currently supported by the DS."

If I set the stream.transcode property to "flac:wav24;", thereby invoking FFMPEG, I get the same result as attempting to play the FLAC stream without transcoding. The same is true of "flac:wav24-0KB", and, now that I have repeatedly changed the transcode setting, also of the original "flac:wav24", where there is no longer a recognition of the playlist entry, and error messages are not being produced.

As I told you in my PM, I think that the cause of the problem is Version 50 and later of the Linn Davaar firmware. This, we know, involved a complete re-write of all the rendering routines. The DSM is happy to play my locally stored FLAC files transcoded to WAV24, but is not accepting transcoded radio streams. The normal BBC streams play perfectly well when not transcoded.

I'd be grateful for advice on what further settings to try. Alternatively, if there is anything I can do to help with diagnosing the problem please let me know. I can report the problem to the Linn team, but they are more likely to respond if I can give them specific information.
