Description:

[ CCode ( cname = "gst_type_find_helper_for_buffer_with_caps" ) ]
[ Version ( since = "1.22" ) ]
public Caps? type_find_helper_for_buffer_with_caps (Object? obj, Buffer buf, Caps caps, out TypeFindProbability prob)

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

Tries to find what type of data is contained in the given data, the 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 null if the content of the data could not be identified.

Free-function: gst_caps_unref

Parameters:

obj

object doing the typefinding, or null (used for logging)

buf

a Buffer with data to typefind

caps

caps of the media

prob

location to store the probability of the found caps, or null

Returns:

the Caps corresponding to the data, or null if no type could be found. The caller should free the caps returned with gst_caps_unref.
