I have tried to cast 24bit 192kHz flac to GMediaRender DLNA Renderer but it seems that either Hi-Fi Cast or the Renderer itself don't support that format. Hi-Fi Cast doesn't tell me that it is a 192k file at all, it says 'FLAC' and that's all. I want to transcode this kind of format to a compatible format, maybe WAV or LPCM or just downsample it to 16bit 48kHz but I didn't find anything useful to do that other than using other applications.
So, am I missing something? If not, will this feature be added in the future?
