New MPF Components

I'm in the process of migrating some new MPF components into the public MPF space.  These components are:

Quick skim of "Automated Metadata in Multimedia Information Systems"

I just skimmed "Automated Metadata in Multimedia Information Systems - Creation, Refinement, Use in Surrogates, and Evaluation" Turns out the lecture is by Mike Christel of CMU, which I hadn't noticed ... it's a quick read, and worth the hour it takes. Here's my quick notes:

Some interesting tidbits he cites re ASR results:

The following is a high-level view of how we plan to stich together the speech recognition system. I'm especially interested in feedback on mime types for the various data flows. I'll post seperately on specific components as well.

mpf-xml-pipeline-dump component

Published June 8, 2009, 9:02 am | by stuffs

I have committed a new component to SVN to assist with diagnosing MPF (and gstreamer) pipelines: MPF/components/mpf-xml-pipeline-dump.  This component acts as an identity transform, but will dump the structure of the pipeline on the first call to component_process.  The default is a dump to stdout, but the component also supports a "location=filename" parameter to place the XML in a named file.  The dump is performed by the gst_xml_write_file function, and is rather verbose. 

Segmenter Component (mpf-segmenter)

I just committed a first version of a stream segmenter component: mpf-segmenter.  This component works together with a time-of-interest component (mpf-toi) to chop a stream up into segments of interest. Both mpf-toi and mpf-segmenter are in the public SVN tree under the MPF/components directory, and require a current build of GRDF which implements node comparison functions for uri and anon nodes.

Time Of Interest Component (mpf-toi)

I have checked in a first version of the mpf-toi (Time Of Interest) component.  This will allow for segmenting or analyzing media streams based on the stream time.  The source code is in MPF/trunk/components/mpf-toi in the svn repository.
