Expand description

Tries to find if type of media contained in the given gst::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 None if the content of the data could not be identified.

Free-function: gst_caps_unref


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


a gst::Buffer with data to typefind


caps of the media


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().


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