Media Center Core Commands

Each command has a "what command" (i.e. MCC_PLAY_PAUSE) and also an optional parameter, which is explained by the comment following the command. If you don't use the parameter, set it to '0'.

The full, C++ header (may be newer than the wiki) is available here: J. River Media Core Commands Header File

Note: You may need to save the MCCommands.h file to your hard drive for the line breaks to appear correctly.

Remember that some commands may only work with the latest version of Media Center.

How To Issue Media Core Commands

Post a WM_MC_COMMAND based message to the MC frame

C++ Example:

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

Fire the same command through the launcher (i.e. 'MC12.exe') in the system directory

MC12.exe /MCC 10000, 0

Zones

To issue a Playback command to a specific zone, mask these values with the parameter:

Current: 0         (0x00000000 hex)
Zone 0:  16777216  (0x01000000 hex)
Zone 1:  33554432  (0x02000000 hex)
Zone 2:  50331648  (0x03000000 hex)
Zone 3:  67108864  (0x04000000 hex)
Zone 4:  83886080  (0x05000000 hex)
Zone 5:  100663296 (0x06000000 hex)
...
Zone 31: 520093696 (0x1F000000 hex)

For the geeks, the actual parameter is bits 0-23 and the Zone is bits 24-29 of the 32-bit parameter (see the C++ macros below if you like). If bit 32 is set, Media Center assumes you passed in a simple negative number, so the Zone portion is discarded.

Creating the final parameter value:

For parameters >= 0
 final parameter value = Zone mask + parameter

For parameters < 0
 final parameter value = Zone mask + (16777216 + parameter)

Example:

parameter -1 to Zone 3: 67108864 + (16777216 + -1) = 83886079
