Original commit message from CVS: * gst/mxf/mxfaes-bwf.c: (mxf_metadata_wave_audio_essence_descriptor_parse): * gst/mxf/mxfaes-bwf.h: * gst/mxf/mxfdemux.c: (gst_mxf_demux_pull_range), (gst_mxf_demux_pull_klv_packet), (gst_mxf_demux_parse_footer_metadata), (gst_mxf_demux_handle_klv_packet), (gst_mxf_demux_pull_and_handle_klv_packet), (gst_mxf_demux_chain): * gst/mxf/mxfmpeg.c: (mxf_metadata_mpeg_video_descriptor_parse): * gst/mxf/mxfmpeg.h: * gst/mxf/mxfparse.c: (mxf_timestamp_parse), (mxf_fraction_parse), (mxf_utf16_to_utf8), (mxf_product_version_parse), (mxf_partition_pack_parse), (mxf_primer_pack_parse), (mxf_local_tag_parse), (mxf_metadata_preface_parse), (mxf_metadata_identification_parse), (mxf_metadata_content_storage_parse), (mxf_metadata_essence_container_data_parse), (mxf_metadata_generic_package_parse), (mxf_metadata_track_parse), (mxf_metadata_sequence_parse), (mxf_metadata_structural_component_parse), (mxf_metadata_generic_descriptor_parse), (mxf_metadata_file_descriptor_parse), (mxf_metadata_generic_sound_essence_descriptor_parse), (mxf_metadata_generic_picture_essence_descriptor_parse), (mxf_metadata_cdci_picture_essence_descriptor_parse), (mxf_metadata_multiple_descriptor_parse), (mxf_metadata_locator_parse): * gst/mxf/mxfparse.h: Use guint instead of guint64 or gsize for all buffer sizes and use correct format strings for them. Only local tag set sizes are still guint16 as they can't be larger. Only allow KLV packets of sizes below 1<<32 as GStreamer only uses guint for buffer sizes. The MXF standard allows packet sizes up to 1<<64.
