MediaPipe CLI

The MediaPipe Command-Line Interface (CLI) provides a straight forward way to use the MediaPipe Framework. You can either build or load a pipeline and execute it from the terminal. This makes it easy for you to use other tools, such as Perl or AppleScript, to automate MediaPipe. RNC's MissingMpegTools (MMT) is a perfect example of how the command-line version of MediaPipe can be used through scripting.

The parameters to mediapipe look like this:

mediapipe <selector> [<arguments>]

The Selectors

-list

"-list" lists all the pipes that mediapipe found and loaded. If you have pipes installed in multiple locations, you might want to look at the path of the pipe to see which one has been loaded.

Eg.
mediapipe -list

-attributes

Eg.
mediapipe -attributes "File Browser"

-pipeline

mediapipe -pipeline [flags] [pipe attr=val] [! pipe attr=val] ...

Note that the '!' has the effect of joining the output of one pipe with the input of the following one

The possible flags are:

• "-d <directory>" indicates where the files output by the pipeline should be saved
• "-f <file>" tells mediapipe to use a saved pipeline
• "-s <file>" tells mediapipe to save the pipeline instead of executing it

Here are a few examples:

Building and Executing a Pipeline
mediapipe -pipeline "File Browser" Path=/Users/mobodo/clip.mov ! "QuickTime Decoder" ! Preview

Building and Saving a Pipeline
mediapipe -pipeline -s pipeline.mpline "File Browser" Path=/Users/mobodo/clip.mov ! "QuickTime Decoder" ! Preview

Loading and Executing a Pipeline
mediapipe -pipeline -f pipeline.mpline
