Is there support in MusicBee's WinAmp (Output Plug-in) API for getting the length of the current track? WinAmp supports this in 2 ways:
SendMessage(window, WM_WA_IPC, (LPARAM) IPC_GETOUTPUTTIME, (WPARAM) 2, &error, &result);
time_t length = (time_t) result;
void GetBasicFileInfo(time_t& length, const wchar_t* const filePath, HWND hWnd)
fileInfo.filename = filePath;
fileInfo.quickCheck = 0;
fileInfo.title = NULL;
fileInfo.titlelen = 0;
fileInfo.length = 0;
SendMessageWithTimeout(hWnd, WM_WA_IPC, IPC_GET_BASIC_FILE_INFOW, (WPARAM) &fileInfo);
if (fileInfo.length > 0)
length = static_cast<time_t>(fileInfo.length) * 1000;
IPC_GET_BASIC_FILE_INFOW is 1291. There is an older message 291 for non-wide chars as well.
I have been using the MusicBee IPC plug-in, which uses the standard MusicBee API and gives me access over IPC. However, that plug-in seems to have been wiped from the internet.
