name: string

Methods

getLength

getLength(data: object): number

- Defined in Gst-1.0.d.ts:23302
Parameters
- data: object
Returns number

peek

peek(data: object, offset: number, size: number): number

- Defined in Gst-1.0.d.ts:23295
Parameters
- data: object
- offset: number
- size: number
Returns number

suggest

suggest(data: object, probability: number, caps: Gst.Caps): void

- Defined in Gst-1.0.d.ts:23296
Parameters
- data: object
- probability: number
- caps: Gst.Caps
Returns void

suggestEmptySimple

suggestEmptySimple(probability: number, mediaType: string): void

- Defined in Gst-1.0.d.ts:23315
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

Static register

register(plugin: Gst.Plugin, name: string, rank: number, func: Gst.TypeFindFunction, extensions: string, possibleCaps: Gst.Caps): boolean

- Defined in Gst-1.0.d.ts:23342
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
