Help ! Synology / Minimserver / Ministreamer / Bubble / Lumin app / Chromecast Audio

[Snico]

Hello,

I managed to install Minimserver and Bubbleupnp on my Synology DS212j.
Control app is the Lumin on Ipad, Rendered is a Chromecast Audio.
I works, ..but i need to transcode alac and dsd that are not supported by Chromecast.
So I installed Minimstreamer. This is where I need help: now the chromecast doesn't play anything anymore from Minimserver (it works with other apps).
I think I missed something with ffmpeg and that minimstreamer doesn't transcode. Or is Bubbleupnp trying to transcode also and there is a conflict ?..

Thanks for your help.

Nicolas
