Methods

  • getLength(data: object): number
  • peek(data: object, offset: number, size: number): number
  • Parameters

    • data: object
    • offset: number
    • size: number

    Returns number

  • suggest(data: object, probability: number, caps: Gst.Caps): void
  • suggestEmptySimple(probability: number, mediaType: string): void
  • If a #GstTypeFindFunction calls this function it suggests caps of the given media_type with the given probability.

    This function is similar to gst_type_find_suggest_simple(), but uses a #GstCaps with no fields.

    Parameters

    • probability: number

      The probability in percent that the suggestion is right

    • mediaType: string

      the media type of the suggested caps

    Returns void

  • Registers a new typefind function to be used for typefinding. After registering this function will be available for typefinding. This function is typically called during an element's plugin initialization.

    Parameters

    • plugin: Gst.Plugin

      A #GstPlugin, or %NULL for a static typefind function

    • name: string

      The name for registering

    • rank: number

      The rank (or importance) of this typefind function

    • func: Gst.TypeFindFunction

      The #GstTypeFindFunction to use

    • extensions: string

      Optional comma-separated list of extensions that could belong to this type

    • possibleCaps: Gst.Caps

      Optionally the caps that could be returned when typefinding succeeds

    Returns boolean
