WinampEasyService

Making it easier to integrate services with good old WinAmp

Goal:

• Make it easier to write plugins and integrate services into WinAmp and WACUP

Installing plugins:

• Put the ml_easysrv and in_easyfngetter plugins in the WACUP Plugins folder
• Also put isrv_managed and isrv_web in the WACUP Plugins folder
• Put any service plugins (esrv_\*.exe, msrv_\*.dll, srv_\*.dll, wsrv_\*.html) in the same folder
• The services will be accessible in the Services tree of the Media Library

Using plugins (Instead of this, plugins can now provide their own custom UI):

• Press the Invoke plugin button to interact with the selected service
• Double click an entry in the list to play it
• Alt + double click an entry in the list to enqueue it
• Right click an entry for more options

Service plugin development:

• Managed (.NET based) DLLs have to be named msrv_\*.dll and contain the msrv.EasyService class implementing the following:
  • public void InitService(Dictionary<string, object> functionDict, string pluginDir, uint serviceID)
    • functionDict contains the following functions:
      • string GetOption(string optionName, string defaultValue)
      • void SetOption(string optionName, string optionValue)
      • void SkinForm(Form form)
  • public Tuple<string, string, string, uint> GetNodeDesc() should return a tuple with the following information:
    • Category
    • Node name you wish to show in the Media Library
    • The column names you wish to show in the Media Library, delimited by \t
    • Capabilities (0):
      • const uint CAP_DEFAULT = 0; for no additional capabilities
      • const uint CAP_CUSTOMDIALOG = 1; for custom UI support
  • public List<List<string>> InvokeService(IntPtr hwndWinampParent, IntPtr hwndLibraryParent, IntPtr hwndParentControl, string skinPath) should return the entries to populate the Media Library ListView with
    • The inner lists should always contain three strings in this order: Column contents delimited by \t, Title to show in the playlist, Filename
    • The filename can be a direct filename (e.g. e:\\example.mp3) or a reference (e.g. ref_examplefile)
  • Optional: public string GetFileName(string fileID) should return the direct filename when called with a reference
  • Important: If you wish to show a window, call ShowWindow(form.Handle, SW_SHOW); on your Form after creation
    • ShowWindow resides in user32.dll, SW_SHOW equals 5
  • Full example: WinampEasyService\\msrv_exampledll
• Managed (.NET based) DLLs with custom UIs have to be named msrv_\*.dll and contain the msrv.EasyService class implementing the following:
  • public void InitService(Dictionary<string, object> functionDict, string pluginDir, uint serviceID)
    • functionDict contains the following functions:
      • string GetOption(string optionName, string defaultValue)
      • void SetOption(string optionName, string optionValue)
      • void SkinForm(Form form)
  • public Tuple<string, string, string, uint> GetNodeDesc() should return a tuple with the following information:
    • Category
    • Node name you wish to show in the Media Library

    • Capabilities (1):
      • const uint CAP_DEFAULT = 0; for no additional capabilities
      • const uint CAP_CUSTOMDIALOG = 1; for custom UI support
  • public UserControl GetCustomDialog(IntPtr hwndWinampParent, IntPtr hwndLibraryParent, IntPtr hwndParentControl, string skinPath) should return the System.Windows.Forms.UserControl you'd like to show
• Unmanaged DLLs have to be named srv_\*.dll and implement the functions in WinampEasyService\\ml_easysrv\\easysrv.h:
  • void InitService(AddItemFunc addItemFunc, GetOptionFunc getOptionFunc, SetOptionFunc setOptionFunc, const wchar_t\* pluginDir, UINT_PTR serviceID):
    • The function pointers are described in easysrv.h:
      • typedef void (\*AddItemFunc)(const wchar_t\* displayInfo, const wchar_t\* playlistInfo, const wchar_t\* filename, UINT_PTR serviceID);
      • typedef void (\*GetOptionFunc)(UINT_PTR serviceID, const wchar_t\* optionName, const wchar_t\* defaultValue, wchar_t\* output, DWORD outputSize);
      • typedef void (\*SetOptionFunc)(UINT_PTR serviceID, const wchar_t\* optionName, const wchar_t\* optionValue);
  • NodeDescriptor GetNodeDesc() should return a NodeDescriptor struct with the following information:
    • Category
    • Node name you wish to show in the Media Library
    • The column names you wish to show in the Media Library, delimited by \t
    • Capabilities (0):
      • #define CAP_DEFAULT 0u for no additional capabilities
      • #define CAP_CUSTOMDIALOG 1u for custom UI support
  • void InvokeService(HWND hwndWinampParent, HWND hwndLibraryParent, HWND hwndParentControl, wchar_t\* skinPath) should call AddItemFunc as many times as needed
    • Filenames can be direct filenames (e.g. e:\\example.mp3) or references (e.g. ref_examplefile)
  • Optional: const wchar_t\* GetFileName(const wchar_t\* fileID) should return the direct filename when called with a reference

Multiservice plugin development:

• Managed (.NET based) DLLs have to implement the following, in addition to those above:
  • public int GetNodeNum() should return the number of services implemented by the plugin
  • public void SelectService(int multiID) is called to select the currently needed subservice
  • Important: The selected subservice ID should be taken into consideration on subsequent function calls
  • Full example: WinampEasyService\\msrv_examplemulti
• Unmanaged DLLs have to implement the following, in addition to those above:
  • int GetNodeNum() should return the number of services implemented by the plugin
  • void SelectService(int multiID) is called to select the currently needed subservice
  • Important: The selected subservice ID should be taken into consideration on subsequent function calls

  • Full example: WinampEasyService\\esrv_examplemulti

Custom Reference ID usage:

• Declare CAP_CUSTOMREFID in your Capabilities
• Implement GetCustomRefId and return your custom Reference ID
• To declare a playlist entry using a custom Reference ID, the file name yourcustomrefid_ref_examplefile.ref has to be used, instead of the usual ref_examplefile
• Reference handling through GetFileName is unchanged
• Example: WinampEasyService\\refidexample

Custom URL Handling:

• Declare CAP_URLHANDLER in your Capabilities
• Implement GetUrlPrefix and return the prefix of the URLs you want to handle
• URLs have to be handled in GetFileName
