pub fn parse_launch(pipeline_description: &str) -> Result<Element, Error>
Expand description

Create a new pipeline based on command line syntax. Please note that you might get a return value that is not None even though the error is set. In this case there was a recoverable parsing error and you can try to play the pipeline.

To create a sub-pipeline (bin) for embedding into an existing pipeline use parse_bin_from_description().

pipeline_description

the command line describing the pipeline

Returns

a new element on success, None on failure. If more than one toplevel element is specified by the pipeline_description, all elements are put into a Pipeline, which than is returned.
