ProxyStream re-encodes my output source always

[storaid]

Hello, Tiki
Why does ProxyStream always re-encode my output file to FLAC format before outputting it?
This is a bit strange…
No matter if it is FLAC, WAV, AAC, etc., they will be re-encoded…
This mean that TuneBrowser needs to consume resources and wait for the re-encoding operation to complete?
The iFi Stream device I tested, it supports a lot of MIME formats:

http-get:*:application/flac:*
http-get:*:audio/flac:*
http-get:*:audio/x-flac:*
http-get:*:audio/aac:*
http-get:*:audio/x-aiff:*
http-get:*:audio/dff:*
http-get:*:audio/x-dff:*
http-get:*:audio/dsd:*
http-get:*:audio/x-dsd:*
http-get:*:audio/dsf:*
http-get:*:audio/x-dsf:*
http-get:*:audio/m4a:*
http-get:*:audio/x-m4a:*
http-get:*:audio/mp1:*
http-get:*:audio/mp4:*
http-get:*:audio/mpeg:*
http-get:*:audio/x-mpeg:*
http-get:*:audio/ogg:*
http-get:*:audio/vorbis:*
http-get:*:audio/wav:*
http-get:*:audio/x-wav:*
http-get:*:audio/wave:*
http-get:*:audio/x-ms-wma:*
http-get:*:audio/x-ogg:*
http-get:*:audio/x-scpls:*
http-get:*:audio/x-vorbis+ogg:*
http-get:*:audio/x-vorbis:*
http-get:*:video/mp4:*

It’s possible that the TuneBrowser avoids re-encoding operation if the UPnP device does support the output source’s format?

Hello,

You are using CUESHEET. Almost (maybe all) UPnP renderers are not supporting CUESHEET. So, TuneBrowser is extracting part of music file according to CUESHEET.
