ogg-index produces multiple fisbones with the same name and role, where the input has several video or audio streams

If you use OggIndex on a file without a Skeleton stream, which has one Vorbis and one Theora stream in it, the resultant Skeleton fisbones will be correct. However, if you use it on a file with multiple Theora or Vorbis streams, it will generate incorrect fisbones for the second and subsequent streams of the type, as it hard codes the name and role

Instead, OggIndex should check which stream this is of a given type, and use that to assign sequential names (eg audio_1, audio_2) rather than hardcoded (eg audio_1 for everything), and flag subsequent streams of a type as alternate ones (rather than hard coded as the main one)
