Indeed, very silly and inefficient code there (left over from when the demuxer
was ported to 0.10). Thanks for the patch!

        Patch by: Jindrich Makovicka  <jindrich.makivicka at itonis tv>

        * gst/matroska/ebml-read.c: (gst_ebml_read_peek_bytes),
        (gst_ebml_read_pull_bytes), (gst_ebml_read_element_id),
        (gst_ebml_read_element_length), (gst_ebml_read_buffer),
        (gst_ebml_read_bytes), (gst_ebml_read_uint), (gst_ebml_read_sint),
        (gst_ebml_read_float), (gst_ebml_read_ascii),
        (gst_ebml_read_binary):
          Don't create unnecessary sub-buffers all the time. Dramatically
          improves performance with multiple concurrently running
          matroskademux instances (#341818) (and generally avoids doing
          unnecessarily inefficient things).
