== Configuration file parameters for upmpdcli === MPD parameters mpdhost:: Host MPD runs on. Defaults to localhost. This can also be specified as -h host mpdport:: IP port used by MPD Can also be specified as -p port. Defaults to the normal MPD port, 6600 mpdpassword:: MPD password. Password for connecting to *MPD* (only necessary if password access is enabled in the *MPD* configuration file). ownqueue:: Set if we own the MPD queue. If this is set (on by default), we own the MPD queue and will fearlessly clear it. Can also be specified as -q 0|1. === Upmpdcli general parameters friendlyname:: "Friendly Name" for the UPnP Media Renderer. This will be displayed by most Control Points to identify the Renderer. Some OpenHome Control Points may display the 'ohproductroom' value instead. upnpav:: Enable UPnP AV services (0/1). This is set by default, but it may useful to switch it off with some OpenHome Control Points which are too easily confused by the presence of UPnP AV services. openhome:: Enable OpenHome services (0/1). This defaults to 1, as OpenHome queuing is superior for most usages. There should be little reason to turn it off. logfilename:: Log file name. Defaults to stderr. This can also be specified as -d logfilename. loglevel:: Log level. 0-4. Can also be specified as -l loglevel. checkcontentformat:: Check that input format is supported. Extract the protocolinfo information from the input metadata and check it against our supported formats. Set this option to 0 if a control point or media server sends good audio data with bad metadata. Default 1. iconpath:: Path to the Renderer icon. The image will be displayed by Control Points which support it. The UPnP protocol has provisions for a renderer to send the URL to a descriptive icon as part of the device description. Due to current (and probably permanent) *upmpdcli* limitations, the image file *must* be a 64x64 32 bits-per-pixel png file. Default: '$pkgdatadir/icon.png'. The icon will only be read once, when upmpdcli starts up. pkgdatadir:: XML and other constant data storage directory. Default: '$prefix/share/upmpcli' (e.g.: '/usr/share/upmpdcli'). cachedir:: Directory used to store cached data Only used for the OpenHome queue metadata for now. The default value is ~/.cache/upmpdcli for normal users or /var/cache/upmpdcli when upmpdcli is started as root. presentationhtml:: Path to the presentation HTML document You can change it to replace the default presentation page. The page will only be read once, when upmpdcli starts up. It can't presently be used for status updates (but I guess that you could put a redirect in there, to something more dynamic served by a real HTTP server). Default: '$pkgdatadir/presentation.html'. pidfile:: Name of lock file used to store the current process pid. Only used if the process is launched by user root. Used by the init system, and to avoid multiple instances. The only reason to change the value is if you actually want to have several instances running (also change cachedir in this case). === UPnP network parameters upnpiface:: Network interface to use for UPnP. libupnp/pupnp only supports communicating on a single interface and will use the first found, this allows forcing the use of another interface. upnpip:: IP address to use for UPnP, alternative to using an interface name. upnpport:: Port number used for UPnP. libupnp/pupnp defaults to using the first free port after 49152. Note that clients do not need to know about the value, which is automatically discovered. === Audio control hooks onstart:: Command to run when playback is about to begin. Specify the full path to the program, e.g. /usr/bin/logger. onplay:: Command to run when MPD state switches to "PLAY". Specify the full path to the program, e.g. /usr/bin/logger. onstop:: Command to run when MPD state switches to "STOP". Specify the full path to the program, e.g. /usr/bin/logger. externalvolumecontrol:: Use external commands to manage the the sound volume (0/1). This is used in the case where MPD is unable to control the volume, but some other command can, for example if you have an external amp on which it is possible to set and read the volume through scripts. If set, the calls to MPD to set and read the volume will be replaced by executions of 'onvolumechange' and 'getexternalvolume' getexternalvolume:: Command to run for reading the sound volume. The command should write a 0-100 numeric value to stdout. onvolumechange:: Command to run to set the volume. Used when 'externalvolumecontrol' is set. Specify the full path to the program, which is called with the volume as the first argument, e.g. /some/script 85. === OpenHome parameters radiolist:: Path to an external file with radio definitions. Radio stations can be defined at the end of the the main file, or in a separate one (or both). Using an external file can ease distribution to multiple machines. Either way, each radio station is defined as a section with a name beginning with "radio", containing an URL parameter, and an optional icon URL. Example: ---- [radio My Radio] url = http://some.host/some/path.pls artUrl = http://some.host/icon/path.png ---- ohmanufacturername:: Manufacturer name. Does not vary at run-time. ohmanufacturerinfo:: Manufacturer information. Does not vary at run-time. ohmanufacturerurl:: URL for manufacturer web site. Does not vary at run-time. ohmanufacturerimageuri:: Uri for manufacturer’s logo. Does not vary at run-time. ohmodelname:: Model name. Does not vary at run-time. ohmodelinfo:: Model information. Does not vary at run-time. ohmodelurl:: URL for model web site. Does not vary at run-time. ohmodelimageuri:: Uri for model’s icon. Does not vary at run-time. ohproductname:: User-visible product name. By default this is set to ModelName. ohproductroom:: The name of the room where the Product is located. Set to “Main Room” by default, displayed in place of the "friendly name" by some control points. ProductRoom is used to group the Product with other related Products in the same physical room (e.g. a source with a pre-amp). Products which are physically linked must always share the same ProductRoom name. ohproductinfo:: Product information. Does not vary at run-time. ohproducturl:: URL for product web site. This may be the UPnP presentation page. ohproductimageuri:: Uri for product image. Does not vary at run-time. ohmetapersist:: Save queue metadata to disk (0/1). This allows persistence of the metadata information across restarts, the default is 1, and there is no reason to turn it off. ohmetasleep:: Mimimum interval (Seconds) between two cache saves. Increasing this may improve playlist load speed on a slow device. The default is to start a new save as soon as the previous one is done (if the list changed again inbetween). === Songcast Receiver parameters sclogfilename:: Log file name for sc2mpd (default stderr) The value *must not* be the same as the one used for upmpdcli. scloglevel:: Log verbosity for sc2mpd. scplaymethod:: sc2mpd play method (mpd/alsa). With this set as 'alsa', sc2mpd will send the audio directly to the sound driver, which is the only way to really avoid skips and control the synchronization in multi-room setups. schttpport:: Port used by sc2mpd for MPD to connect to. Used only for scplaymethod=mpd. sc2mpd only accepts connections from localhost. scalsadevice:: Alsa device used by sc2mpd for playing audio. Only used for scplaymethod=alsa. Use 'aplay -L' to see the possible values. sccvttype:: sc2mpd resampling method. Only used for scplaymethod=alsa. sc2mpd uses libsamplerate. The default method is SRC_SINC_FASTEST and a Rasberry Pi 1 is fast enough to use it. Possible values: SRC_SINC_BEST_QUALITY, SRC_SINC_MEDIUM_QUALITY, SRC_SINC_FASTEST, SRC_ZERO_ORDER_HOLD, SRC_LINEAR. See the libsamplerate documentation for descriptions. Anything above SRC_SINC_FASTEST needs a serious CPU. BEST_QUALITY uses approx 25% cpu on a core i7 4770T. Obviously too much, actually might not be sustainable (it's almost 100% of 1 cpu). MEDIUM_QUALITY is around 10% on the same machine, FASTEST is 4-5%. Given that this is measured for the full process, probably a couple % for the conversion in fact. sc2mpd:: Path to sc2mpd. Only useful if it is not in /usr/bin and the location is not in the $PATH for the init scripts. === Songcast Sender parameters scsenderpath:: Path to the script which starts the auxiliary mpd and the sender process. scstreamscaled:: Decide if we scale the songcast stream. If set, MPD software volume control will be applied to the stream. True by default: using a Control Point to set the volume on the upmpdcli instance which started the Sender affects the volume for all Receivers. scsendermpdport:: localhost port to use by the auxiliary mpd. scripts_dir:: Location for the scripts used to set up additional external sources. See the Songcast Sender support documentation page.
