I’ve defined some simple tagging script which saves a tag with some string $set(Test, foobar).
The tagging script is working fine for
mp3. Instead for a
m4a-file the tag is not written at all. All other standard tags are written correctly.
The custom tag also appears in the tag panel below in Picard for
m4a-files the custom tag appears together with the standard tags when the album information is loaded by Lookup on the right panel (without any file associated). As soon as an unmatched track is associated to the album the custom tag vanishes from the tag panel and won’t be written to the
It is not related to the kind of custom tag. Behaviour is the same for any custom tag.
OS are macOS or Windows 7 x64, the debug log doesn’t contain any related strings. Anyway it is the same for
flac. (BTW, any reason why script actions aren’t logged in debug modus?)
Any hint what’s going on?
