Media Center Core Commands

See also: DevZone

MC Core Commands are used to control various aspects of Media Center via software or command line. Each command consists of a name (or number), followed by an optional parameter which selects or specifies the particular command behavior.

The full, C++ header is available here: JRiver Media Core Commands Header File

Notes

• Save the MCCommands.h file to your hard drive to avoid potential line break issues.
• Commands have changed over time; use the Wiki's page history to see previous versions of this page. Some commands may only work with the latest version of Media Center.

How To Issue Media Core Commands

Look up the command name / number and its parameter in the tables below. For example, the command to toggle between play and pause is MCC_PLAY_PAUSE. It has command number (enum value) 10000 and its accompanying parameter is ignored. Some MCC commands may be targeted a particular Zone - see Specifying Zones.

Issuing a command from the command line

Assuming you are familiar with the first section of The Command Line, the general syntax for issuing an MCC command from the Windows command line (or equivalent) is:

MC<version>.exe /MCC <command number>,<parameter>

Note: Command numbers must be used; command names are not used on the command line.

Example: To toggle between play and pause in MC16, use the command:

MC18.exe /MCC 10000,0

Note: The MCC commands can be entered in Vista and Windows 7 directly into Search Files and Programs under the Windows Start menu, or as commands in a Windows command shell, which can be launched in Vista and Windows 7 by entering cmd.exe in Search Files and Programs under the Windows Start menu. It is available under the Accessories menu as Command Prompt in previous versions of Windows.

On Mac:

/Applications/Media\ Center\ <version>.app/Contents/MacOS/Launcher.app/Contents/MacOS/Launcher /MCC <command number>,<parameter>

On Linux:

/usr/lib/jriver/MC<version>/mc<version> /MCC <command number>,<parameter>

Issuing a command from C++

The calling syntax for posting a WM_MC_COMMAND -based message to the MC frame is demonstrated in the example below.

Example: To post a command to toggle between play and pause

HWND hwndMC = FindWindow(_T("MJFrame"), NULL);
PostMessage(hwndMC, WM_MC_COMMAND, MCC_PLAY_PAUSE, 0);

Notes on usage

• Use command numbers when calling from the command line, enum names from within software (e.g. MCC_PLAY_PAUSE).
• Set parameter to 0 if unused.

Specifying Zones

Media Center Core Commands are targeted to a specific playback zone by combining the command's parameter value with the zone specifier value from the Zone Specifiers table. MC zones are integer indexes, from 0 to n, where 0 is the the first local zone, 1 is the second local zone, and so on. Remote zones, such as those for DLNA devices, will not be contiguous with local zones. A list of zones can be obtained using the MCWS command:

http://<server IP>:52199/MCWS/v1/Playback/Zones

MC version 16.0.118 has simplified command line specification of parameter and zone, eliminating the need for manual calculations prior to usage. The /MCC option now accepts an alternate syntax in the format of [value]:[zone index] for the parameter (see examples). The text that follows documents and describes the original (and still valid) specification, which would be used when issuing an MCC command through a mechanism other than the MC18.exe command.

Technically speaking, the command's parameter is OR'd with the zone specifier value, where bits 0 - 23 specify the command parameter, and bits 24 - 29 specify the zone. For command line usage, the final parameter value to pass to Media Center can be calculated as follows:

• If the parameter is >= 0, the final value = zone specifier + parameter
• If the parameter is <   0, the final value = zone specifier + parameter + 16777216

Examples

• Increase volume to 25% for Zone 2 (new parameter specification available starting with MC 16.0.118)
  • MC18.exe /MCC 10020,25:2

• Increase volume to 25% for Zone 2
  • The MCC_VOLUME_SET command has command number 10020
  • The desired parameter value is 25
  • Zone 2 in the Zone Specifier table indicates a value of 50331648 (0x03000000 hex)
  • Zone specifier (50331648) + parameter value (25) = 50331673 (0x3000019 hex)

• Toggle pause for Zone 3
  • The MCC_SET_PAUSE command has command number 10022
  • The desired parameter value is -1 (toggles)
  • Zone 3 in the Zone Specifier table indicates a value of 67108864 (0x04000000 hex)
  • Zone specifier (67108864) + parameter value (-1) + 16777216 = 83886079 (0x4FFFFFF hex)

Notes

• When bit 32 is set, the zone portion is ignored, and Media Center assumes the parameter is a negative number.
• See the C++ macros below for more information.

The look-up table below shows some pre-calculated parameter values for each of zones 0 through 5 for some typical commands. Find the desired operation, command and command number, and select the cell under the desired zone to obtain the final parameter value.
