Removal of ID3v2 header from FLAC files

[David Troendle]

Hi Lukáš,

Thanks for the feedback and your work on this project.

FYI, I was trying to do what "bool TagLib::MPEG::File::strip  ( int  tags =
AllTags   )" does for TagLib::MPEG::Files.

Regards.

David

There isn't any officially supported way at the moment. Even if you would
manage to make FLAC::File::ID3v2() return NULL, it would not delete the tag.
The TagLib::FLAC::File class must be modified to support this, as it has
information about the original ID3v2 tag.
Something like this should be added at the right place in
TagLib::FLAC::File::save():

removeBlock(d->ID3v2Location, d->ID3v2OriginalSize);

I'll try to implement it for the next TagLib release.

Lukas
