Subject: audiod: Make default filters work also for udp streams.
X-Git-Tag: v0.4.2~29
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=081ea8699e6a309c44446884b8c3752529d96a25;p=paraslash.git

audiod: Make default filters work also for udp streams.

Currently one has to use --no_default_filters and must specify fecdec as the
first filter for UDP streams, a fact that is not documented anywhere. Make decoding
of udp streams work if no filters were given by changing init_default_filters() to
add fecdec automatically if the udp receiver is used.

 	  for the new buffer tree API.
 	- Fix audible buffer underruns for wma streams.
 	- The alsa writer no longer prints meaningless underrun durations.
+	- audiod: Defaults work also for udp streams. If no filter is
+	  given for an audio format that is received via upd, fecdec is
+	  automatically added as the first filter (along with the decoder).
