Selective transcoding possible?

[rt1440]

That failover option indeed looks like a very useful feature.

Unfortunately it doesn't seem to be handled correctly at the other end by the OpenHome Soft Player renderer build I am testing (v1.0.6). Whether I use Linn Kazoo (on iOS) or BubbleUPnP (on Android), the transcoded ALAC stream (set up as alac:-/wav) is handed off correctly - it can be seen in the renderer's playlist. But the renderer does nothing with the ALAC stream, and also doesn't fail over to the alternate WAV stream. I do know it at least plays 16-bit 44100 Hz streams encoded in WAV, FLAC, or AAC (haven't tested other types like Ogg, etc).

I really like the OpenHome feature of offloading the playlist from the control point to the renderer, so I am going to try upmpdcli next, which I believe has some OpenHome support built in.

(In case anyone else is interested in the OpenHome Soft Player: the Media Renderer Analyzer tool by whitebear gave me some insight into what the renderer actually supports. Below is an excerpt from that tool's report.)

Code:
