pub fn type_find_helper_for_data_with_caps(
    obj: Option<&impl IsA<Object>>,
    data: &[u8],
    caps: &CapsRef,
) -> (Option<Caps>, TypeFindProbability)
Expand description

Tries to find if type of media contained in the given data, matches the caps specified, assumption being that the data represents the beginning of the stream or file.

Only the typefinder matching the given caps will be called, if found. The caps with the highest probability will be returned, or None if the content of the data could not be identified.

Free-function: gst_caps_unref

§obj

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

§data

a pointer with data to typefind

§caps

caps of the media

§Returns

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

§prob

location to store the probability of the found caps, or None
