Check the clock difference between the host running para_server
and the local host running para_audiod that many times before
starting any stream I/0. Set this to non-zero for non-local
- setups if the clocks of these two hosts are not syncronized
+ setups if the clocks of these two hosts are not synchronized
by ntp or similar.

- This option may be given multiple times, once for each
- supported audio format. The \"receiver_spec\" consists of
- an audio format and the receiver name, separated by a colon,
- and any options for that receiver, seperated by whitespace.
- If any receiver options are present, the whole receiver
- argument must be quoted.
+ This option may be given multiple times, for each audio format
+ separately. If multiple definitions for an audio format are
+ given, the first one is selected.
+
+ The \"receiver_spec\" consists of an audio format specifier
+ and one or more receiver arguments, separated by a colon.
+
+ The audio format specifier is a regular expression which
+ specifies the set of audio formats for which this option
+ should apply.
- Example:
+ If any receiver options are present, the whole receiver
+ argument must be quoted:
-r 'mp3:http -i my.host.org -p 8009'
+
+ Since a single dot '.' matches the name of any audio format,
+ specifying '.' instead of 'mp3' above activates the http
+ receiver for all audio formats.

If (and only if) this option is set, the --filter options

- You have to configure filters manually if you want to use
- the amp filter or the compress filter which are not activated

- Playing udp streams also requires manual filter configuration
- because the output of the udp receiver must be fed into the
- fecdec filter first to produce a stream which can be decoded
- by the appropriate decoder (mp3dec, oggdec, aacdec). In other
- words, the fecdec filter must be specified as the first filter
- of the filter chain for any udp stream.

+
+ For http streams, only a single filter per audio format,
+ the decoder for that format, is activated. On the other hand,
+ since udp and dccp streams are sent fec-encoded by para_server,
+ the client side must feed the output of the receiver into
+ the fecdec filter first. Therefore the default for udp and
+ dccp streams is to activate the fecdec filter, followed by
+ the appropriate decoder.
+
+ You must give this option if you want to use any other filter,
+ for example the amp or the compress filter.
