This is so that complex FFMpeg operations can be abstracted into small amounts of code. You can see the current set of extensions with: ~~~PowerShell Get-RoughDraftExtension ~~~ ### Extension Scripts Extensions are simple scripts files named with the regular expression ```\.(rd|RoughDraft)\.(ext|extension)\.ps1$```. They can exist in any module that adds the tag "RoughDraft". Extensions should include the following attributes above their parameter block: ~~~PowerShell # It's an extension [Runtime.CompilerServices.Extension()] # that extends Edit-Media # (Change this to indicate which command you'd like to extend) # (Add additional Cmdlet attributes one to extend more commands) [Management.Automation.Cmdlet("Edit","Media")] # that is inherited (this is the default). # (an extension that is 'Inherited' will return control to the main function when it is done.) # (an extension that is 'NotInherited' will run and return directly) [ComponentModel.Inheritance("Inherited")] param( # At least one parameter of the extension should be mandatory. [switch] $MyEditExtension ) ~~~ ### Commands that can be extended: The following commands can currently be extended: * Convert-Media * Edit-Media * Get-FFMpeg * Get-Media * Join-Media * New-Media * Show-Media * Split-Media |
