Minim stream being throttled on QNAP NAS ?

[bubbleguuum]

I have just read the last page of this long thread.

In the Media Renderers page, all settings under "Audio decoding to PCM (FFmpeg)" to PCM will be grayed out (disabled) if either ffmpeg or ffprobe or both are not found. Here it is probably just ffprobe being not found (Syno does not has it by default).
When that section is grayed out, nothing is ever touched by FFmpeg and it is entirely disabled.

The "Audio transcoding supported" line is the Status tab can be misleading as it only refers to transcoding audio in videos, when using BubbleUPnP Server is used to access a remote video UPnP/DLNA media server for playing videos on an Android device (eventually transcoded, configurable in Android BubbleUPnP Settings), which was one of the first functionality it supported. Thus not related to OpenHome PCM audio transcoding, implemented much later.
