Additional httpd outputs can be configured using the following variables:
| VARIABLE | DESCRIPTION |
|---|---|
| HTTPD_OUTPUT_CREATE | Set to yes if you want to create an additional httpd output |
| HTTPD_OUTPUT_ENABLED | Sets the output as enabled if set to yes, otherwise mpd's default behavior applies |
| HTTPD_OUTPUT_NAME | The name of the httpd output, defaults to httpd |
| HTTPD_OUTPUT_PORT | The port for the httpd output stream, defaults to 8000 if not specified |
| HTTPD_OUTPUT_BIND_TO_ADDRESS | Allows to specify the bind address |
| HTTPD_OUTPUT_ENCODER | The encoder defaults to wave, see here for other options |
| HTTPD_OUTPUT_ENCODER_BITRATE | Encoder bitrate. Refer to the encoder documentation |
| HTTPD_OUTPUT_ENCODER_QUALITY | Encoder quality. Refer to the encoder documentation |
| HTTPD_OUTPUT_MAX_CLIENTS | Sets a limit, number of concurrent clients. When set to 0 no limit will apply. Defaults to 0 |
| HTTPD_OUTPUT_ALWAYS_ON | If set to yes, then MPD attempts to keep this audio output always open. This may be useful for streaming servers, when you don’t want to disconnect all listeners even when playback is accidentally stopped. Defaults to yes |
| HTTPD_OUTPUT_TAGS | If set to no, then MPD will not send tags to this output. This is only useful for output plugins that can receive tags, for example the httpd output plugin. Defaults to yes |
| HTTPD_OUTPUT_FORMAT | The output format, defaults to 44100:16:2 |
| HTTPD_OUTPUT_MIXER_TYPE | Set to software if you want to be able to change the volume of the output stream |
The port number default is calculated for each index by incrementing the default (8000) value.
When using multiple httpd outputs, remember to open all the relevant ports, not only 8000, otherwise only the first output will work.
