Add `option.mkvUseIndex` to use index to skip Matroska cluster elements #2219

Closed Borewit closed 3 months ago

Borewit commented 3 months ago

Change EBML iterator and Matroksa parser so that, that it processes the metadata found in elements during parsing, rather then when the entire file is parsed.

Adds flag options.mkvUseIndex, which is by default: false, if set to true, in Matroska based files, use the SeekHead element index to skip segment/cluster elements.. experimental functionality Can have a significant performance impact if enabled. Possible side effect can be that certain metadata maybe skipped, depending on the index. If there is no SeekHead element present in the Matroska file, this flag has no effect.
