Details

libavmasf.so is a Metadata extractor for Microsoft audio and video formats.
It is only used by fritznasdb, the media database server.

The name comes from the ASF container format, which is a proprietary successor of the RIFF format.
Most famous usages of the ASF container are the WMA and WMV formats.

Structures

ASF container structures extracted by libavmasf.so:

  • Header
  • ExtendedContentDescription
  • HeaderExtension
  • Metadata
  • MetadataLibrary
  • StreamPropertiesObject
  • StreamBitratePropertiesObject
  • FilePropertiesObject
  • AudioMedia
  • VideoMedia
  • CodecListObject
  • ContentBrandingObject
  • Extended_Stream_Properties_Object
  • Payload_Extension_System_Pixel_Aspect_Ratio
  • ASF_Content_Encryption_Object
  • ASF_Extended_Content_Encryption_Object

Metadata

Metadata extracted from the ASF container:

  • Title, Author, Copyright, Comment, Rating, Genre (ID3)
  • Codec names and FourCC IDs
  • Extensible wave format Descriptors - see here (audio)
  • Bitrates and Samplerate
  • CBR / VBR, amount of channels (audio)
