Original commit message from CVS: * gst/matroska/ebml-write.c: (gst_ebml_write_float): Use GDOUBLE_TO_BE() instead of (probably slower) custom code. * gst/matroska/matroska-demux.c: (gst_matroska_demux_base_init), (gst_matroska_demux_class_init), (gst_matroska_demux_init), (gst_matroska_track_free), (gst_matroska_demux_encoding_cmp), (gst_matroska_demux_read_track_encodings), (gst_matroska_demux_add_stream), (gst_matroska_demux_handle_src_query), (gst_matroska_demux_init_stream), (gst_matroska_demux_parse_index_cuetrack), (gst_matroska_demux_parse_index_pointentry), (gst_matroska_demux_parse_info), (gst_matroska_demux_parse_metadata_id_simple_tag), (gst_matroska_demux_parse_metadata), (gst_matroska_demux_add_wvpk_header), (gst_matroska_decode_buffer), (gst_matroska_demux_parse_blockgroup_or_simpleblock), (gst_matroska_demux_parse_cluster), (gst_matroska_demux_parse_contents_seekentry), (gst_matroska_demux_loop_stream_parse_id), (gst_matroska_demux_loop), (gst_matroska_demux_video_caps), (gst_matroska_demux_audio_caps), (gst_matroska_demux_subtitle_caps): * gst/matroska/matroska-demux.h: * gst/matroska/matroska-ids.c: (gst_matroska_track_init_subtitle_context): * gst/matroska/matroska-ids.h: * gst/matroska/matroska-mux.c: (gst_matroska_mux_base_init), (gst_matroska_mux_class_init), (gst_matroska_mux_init), (gst_matroska_mux_create_uid), (gst_matroska_mux_reset), (gst_matroska_mux_video_pad_setcaps), (gst_matroska_mux_audio_pad_setcaps), (gst_matroska_mux_subtitle_pad_setcaps), (gst_matroska_mux_request_new_pad), (gst_matroska_mux_track_header), (gst_matroska_mux_start), (gst_matroska_mux_write_simple_tag), (gst_matroska_mux_finish), (gst_matroska_mux_write_data), (gst_matroska_mux_collected), (gst_matroska_mux_set_property): Add many FIXMEs/TODOs all over the matroska muxer and demuxer elements, do some checks for valid values in the demuxer, handle tracktimecodescale in the demuxer, set correct default values for all settings in the demuxer, review and add all missing matroska IDs and some more raw YUV formats, and some trivial cleanup.
