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[edit]

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[edit]

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++[edit]

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.

MC Commands[edit]

Specifying Zones[edit]

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.

Current	0	0x00000000

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)
