I am having a problem with the adaptive bitrate settings in the Android app. I have music in both mp3 and flac formats, and have the max bitrate set to unlimited (wifi) and 256 (mobile). A couple problems I have noticed - (1) flac files are still transcoded to mp3 even while on wifi, and (2) the bitrate for the transcodes is always 128 kbps.
I have checked the transcode and user settings in the server. The command line uses the %b parameter (I have not modified anything from the stock settings here), and the max bitrate for the user is "no limit". The log file shows ffmpeg being called with 128k bitrate, and the resulting filesize delivered to the phone is consistent with 128 kbps... so I'm not sure where else to look to get the bitrate settings working.
