GStreamer support

+ +
+ +

If it's detected at configure time, a new decoder + program disorder-gstdecode is built. It uses the GStreamer + library for audio decoding and sample-rate conversion, among other + features. + +

The decoder has a number of options for controlling the sample-rate and + audio format conversion, allowing various tradeoffs between quality and + processor time. (High-quality conversion can consume more processor time + than decoding, so this is potentially useful on very a small device such as + a Raspberry Pi.

+ +

The GStreamer decoder can also use ReplayGain information stored in + audio files' metadata to adjust playback volume, so that tracks with very + wide dynamic range don't sound really quiet in comparison. This + information can be added using tools such as mp3gain, + vorbisgain, or metaflac. This is turned on by default if + you use the decoder; you can choose between per-album or per-track + settings, or turn it off entirely, using command-line options.

+ +

The GStreamer decoder is not used by default, but it can be enabled + easily enough by dropping something like the following into the server + configuration file: + 

+        player
+        player *.flac execraw /usr/sbin/disorder-gstdecode -ralbum -f-8.0
+        player *.mp2 execraw /usr/sbin/disorder-gstdecode -ralbum -f-8.0
+        player *.mp3 execraw /usr/sbin/disorder-gstdecode -ralbum -f-8.0
+        player *.ogg execraw /usr/sbin/disorder-gstdecode -ralbum -f-8.0
+        player *.wav execraw /usr/sbin/disorder-gstdecode -ralbum -f-8.0
+
