Compatibility: Windows, Mac, Linux. This software is a free and open-source video. The MediaMetadata interface of the Media Session API allows a web page to provide rich media metadata for display in a platform UI.
- Meta tags are specific snippets of text and image content that provide a summary for a webpage. Often meta tag data shows up whenever someone shares a link on social media, in messaging, or in your business chat software 🙌.
- Code MMPython is a Media Meta Data retrieval framework. It retrieves metadata from mp3, ogg, avi, jpg, tiff and other file formats. Among others it thereby parses ID3v2, ID3v1, EXIF, IPTC and Vorbis data into an object oriented struture.
Media files contain properties that describe the contents of the file. In Microsoft Media Foundation, these properties can be categorized as follows:
- Media-type attributes specify the encoding parameters, such as the encoding algorithm (media subtype), video frame size, video frame rate, audio bit rate, and audio sample rate. For more information about media-type attributes, see Media Types.
- Metadata contains descriptive information for the media content, such as title, artist, composer, and genre. Metadata can also describe encoding parameters. It can be faster to access this information through metadata than through media-type attributes.
- DRM properties contain information on usage restrictions. Currently Media Foundation does not support DRM properties through metadata, with the exception of the PKEY_DRM_IsProtected property.
There are two ways to read metadata in Media Foundation:
