The TsMuxStream internal_stream_type field stores the original 'full' stream type (such as Opus), while the stream_type field stores the value that will actually be written into the MPEG-TS packets according to the codec mappings. When checking if input caps are changing stream type, check the original type. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/9430>
