I have just encoded some cd's to m4a using nero's new command-line encoder. I have tagged them with foobar2000, mp3tag and tag&rename. In every case, MC refuses to read the tags. (I always did an 'update library from tags' after re-tagging). The import of these files also took a verrrrry long time. (about an hour for 108 songs).
Renaming to m4a, well, they were already m4a. enabling the mp4 directshow option also gave no result.
I have one of the files
here. As you can see in this image:
no tags are recognized...I can, however, read the tags using itunes, foobar2000 or any of the tagging programs I used.
When I play the files in MC, they are played back using directshow instead of quicktime, as they should.
Strangely enough, when using mp4ip's mp4creator -optimize on the files, the tags get read correctly after updating from tags in MC...However, mp4info showed the tags correctly before optimizing the file. (and let's not forget that itunes showed them too before optimizing...not to mention that I did not find a way to detect the problem with mp4ip tools.)
Quick question!
Is MC11.1 capable of writing tag information to m4a files?
Hope that makes sense
As far as I understand it, it does not and might take a while to get implemented...
