--errors-to and --meter-data options.

  .PP When --errors-to=STDOUT is specified, glasscoder(1) will output error messages on standard output in the
  .PP
                 ER  [priority]  [msg]

         .PP where [priority] is an integer the indicates the priority level of the error as defined by the
       syslog(3) interface and [msg] is a text string describing the error. Each message is terminated by a
       newline character.

         .PP When --meter-data is specified, glasscoder(1) will output realtime audio level information suitable
       for being rendered as an audio meter display in the following format:

         .PP
                 ME  [left-lvlright-lvl]

         .PP where each argument is the current audio level of the corresponding channel in hexidecimal,
       referenced to 0 dBFS. Each message is terminated by a newline character.

         .SH "CONTROL VIA STANDARD INPUT"

         .PP glasscoder(1) supports the following command, sent via standard input:

         .PP
                 MD  [text]

         .PP Send the metadata [text] to the stream. The command should be terminated by newline.

         .SH "CONTROL VIA HTTP"

         .PP If the --metadata-port=port option is given a non-zero value, metadata updates can be sent to the
       stream by means of HTTP calls. For details, see the METADATA section of the glasscoder(1) man page.

         .SH "PROXY CONNECTIONS"

         .PP It is possible to implement proxy connectors for glasscoder(1)'s IceStreamer server through use of
       the --server-pipe command switch. This switch will create a UNIX socket which can be used to pipe in open
       descriptors for player connections by means of ancilliary socket messages with the SCM_RIGHTS message
       type. See the unix(7) man page for more information. A fully worked-out example is also available in the
       GlassCoder source package in the 'src/tests/' subdirectory.
