Bemix is a web-based media player. It supports multiple soundcards and various networked client types, allowing a group to use a centralized server to control several speakers. Commands are issued through URLs, where the URL portion of the address represents the command to be issued, while the GET portion of the URL passes in parameters to the server.
All URLs are relative to http://slugwiki.mit.edu:8080/, and all URLs have an output=[html, client]. An example URL is http://slugwiki.mit.edu:8080/play?output=client&playerId=2. All
... must be properly encoded for URLs.
Each command returns a data structure through HTTP that defines variable names and values. A (variable name, value) combination is referred to as a field. Every command contains at least one
success field, whose value may be either
false. If any tag is
false, it should be assumed that the entire command failed. Each command may optionally return a
comment field as well, whose value gives some indication of why an operation may have failed.
In addition, most commands return additional information about the state of a particular aspect of the bemix server.
Bemix is capable of dumping data in multiple of formats. Currently on "client" and "html" formats are planned, but XML/RDF formats are possibly in the future. The format of the export is indicated in the URL by the mandatory
The "client" output format returns data in a simple newline-delimited list. String values are not delimited by quote characters, and list items are delimited by commas (including a comma after the final element). The format of each line is
name is the name of the variable being returned, and
value is the value of the variable. No whitespace characters are inserted between
The order in which the fields are returned is not guaranteed, and it should not be assumed that all tags will be present or in any particular order.
The MIME type of the client output is 'text/plain'.
