Function gstreamer_base::functions::type_find_helper_for_extension[−][src]

pub fn type_find_helper_for_extension<P: IsA<Object>>(
    obj: Option<&P>, 
    extension: &str
) -> Result<Caps, BoolError>

Expand description

Tries to find the best gst::Caps associated with extension.

All available typefinders will be checked against the extension in order of rank. The caps of the first typefinder that can handle extension will be returned.

Free-function: gst_caps_unref

`obj`

object doing the typefinding, or None (used for logging)

`extension`

an extension

Returns

the gst::Caps corresponding to extension, or None if no type could be found. The caller should free the caps returned with gst_caps_unref().
