This means that the dropout was caused by something at the BBC end rather than anything related to WAV or FLAC.
Please set the logging level to Debug and leave the log window open. After the dropout (wait a few seconds for the music to resume), click 'Save as' in the log window to save a log file. Zip the log file and attach it as a file attachment to a post here. MinimStreamer can recover seamlessly from most dropouts and this log information might enable me to extend this to additional cases.

Presumably, if the maximum size were the 4GB that it should be, the maximum duration would be something over 4 hours?

Yes, a 4GB 24-bit stream would last for over 4 hours. Please follow the procedure described in my previous post and attach a zipped log file for any future dropout to help me understand why the dropout occurred. Many thanks.

Will do. However, the stream has been playing continuously during waking hours since about 20:00 yesterday, and I have had only the one short dropout. I'll record a log if the droputs start to recur. Thanks again for your help: as you gather, I am getting a lot of enjoyment from this new radio listening experience.

Just had a dropout on FLAC before I got around to changing the log settings but found this in the log file anyway - does it help?

hppefully this has captured the dropout that just occurred.

The native FLAC stream is crashing a lot this evening. Does not auto-recover, playback just keeps stopping.

This is a different issue and should not cause a dropout. I am not sure why it happens. I have seen it occasionally myself.

The renderer dropped the connection at 18:25:09.372. A few seconds before this happened, there was a glitch at the BBC end which MinimStreamer recovered. This might be related or it might be coincidence. About 3 seconds later, the renderer (apparently a Linn DS) established a new connection, so you should have been without audio for about 3 seconds or perhaps a bit more because of renderer buffering delay.
If you could send logs from a few more similar occurrences, I could check if the renderer disconnection is always preceded by a BBC glitch. This could be useful information.
For any future log attachments, I would appreciate it if you could zip the logs before you attach them. This saves a significant amount of space in the forum database.

Were you able to capture a log for any of these occurrences? The lack of auto-recovery suggests that this is different from the log that you posted.
RE: BBC Taster - BBC Proms in Binaural sound - Cebolla - 01-08-2017 12:10
Hi Simon
The BBC are currently trialing a number of BBC Proms, live, in experimental '3D' binaural sound. The next one is this evening's Prom 23, Handel - Israel in Egypt:
http://www.bbc.co.uk/taster/projects/proms-binaural-2017/try
The actual MPEG-DASH stream is:
https://vs-dash-ww-rd-live.bbcfmt.hs.llnwd.net/al/proms/client_manifest.mpd
It is currently unavailable, but starts streaming just before the start of the advertised prom and stops just after the prom finishes, I believe.
Unfortuantely, the stream appears to be in regular MPEG-DASH AAC (320kbps), rather than the experimental lossless MPEG-DASH FLAC, which the MinimServer/MinimStreamer prototype doesn't currently appear to support.
Would it be possible for you to update the prototype to also support MPEG-DASH AAC at some point?
