mapping mux vector question
Hello everybody
According to "vorbis-spec-ref.html"
paragraph: "mappings", the vector [vorbis_mapping_mux]
should contain the following:
4.
if [vorbis_mapping_submaps] is greater than one, we read channel multiplex settings.
For each [j] of [audio_channels] channels:
1. vector [vorbis_mapping_mux] element [j] = read 4 bits as unsigned integer
2. if the value is greater than the highest numbered submap
([vorbis_mapping_submaps] - 1),...

...^^^^^^^^^^^^^^^^^^^
is floor1_partition_class correct ? or should it be
floor1_partition_class_list

Help understand decoding of stereo vorbis data
...at I'm handling the submap number/floor mapping incorrectly;
I'm interested in finding out about this from the documentation;
(4.3.2. floor curve decode)
[submap_number] = element [i] of vector [vorbis_mapping_mux]
What happens if during mapping decoding vorbis_mapping_mux is empty because vorbis_mapping_submaps was 1? Do both channels use the single submap in this case?
Also, I'm noticing that in this same situation, I'm getting a vorbis_floor_count of 2. What's the purpose of the second floor in this case, if both channels are referencing the first floor?
Thanks,
