add_param

• add_param(s: Structure): void

  Attach element-specific parameters to meta meant to be used by downstream elements which may handle this ROI. The name of s is used to identify the element these parameters are meant for.

  This is typically used to tell encoders how they should encode this specific region. For example, a structure named "roi/x264enc" could be used to give the QP offsets this encoder should use when encoding the region described in meta. Multiple parameters can be defined for the same meta so different encoders can be supported by cross platform applications).

  Parameters

  • s: Structure

    a Gst.Structure

  Returns void

get_param

• get_param(name: string): Structure

  Retrieve the parameter for meta having name as structure name, or null if there is none.

  Parameters

  • name: string

    a name.

  Returns Structure

  a Gst.Structure

Staticget_info

• get_info(): Gst.MetaInfo

  Returns Gst.MetaInfo
