Parse Id3v1 tags #3

Open notryanb opened 4 years ago

notryanb commented 4 years ago

Currently the rust id3 crate defaults to parsing id3 tags as Id3v2.x. It will fail to parse a tag that is v1. The plugin should fallback to v1 if v2 fails.

Hello

Should the version number be provided as an argument? This way the user could explicitly display v1 or v2 tags. A both argument is also very useful to quickly discover which files have information in both formats which is a bit redundant and may be cleaned in a later operation.

@Delapouite I was thinking this plugin should be parsing a file at the version it supports/specifies and return the version number as a column. nushell can filter the data beyond that with the where command. ex id3 | where Version == "Id3v2.4" or id3 | where Version == "ID3v1".

I am very new to ID3 parsing. I am under the impression that a file can only contain a single version of the ID3 tag, as that is encoded into the header? I am also assuming mixing frames that exist between ID3 versions inside the same tag would be against the standard? I need to do more reading on this.
