mp4tags can't add tags to files created with enhAacPlusEnc #68

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

1. Use enhAacPlusEnc (http://dgaapenc.berlios.de/en/) to create an HE-AAC v2 
file.
2. Try using mp4tags to set a song title: mp4tags -s "My title" file.m4a
3. Confirm that the title was not set: mp4info file.m4a
4. Use any other tagging utility, such as easytag 
(http://easytag.sourceforge.net/) to set any tag.
5. Remove all the tags that were set: mp4tags -r sawEyAtTdDgcP file.m4a
6. Set a song title with mp4tags: mp4tags -s "My title" file.m4a
7. Confirm that the title was set successfully: mp4info file.m4a

What is the expected output? What do you see instead?

If I run

  mp4file --dump file.m4a | grep moov.udta

after step 2, I would see that a moov.udta atom doesn't exist in the file's 
metadata. It looks to me like mp4tags doesn't try to create it (or one of the 
other atoms leading up to moov.udta.meta.©nam) if it doesn't already exist, 
leading to the inability to tag any file produced by enhAacPlusEnc.

This used to work with an older version of mp4tags.

What version of the product are you using? On what operating system?

1.9.1 on Arch Linux i686

Could you attach a small HE-AAC v2 file to this posting that I could test with? 
 Also, have you tried using the r355 release or trunk?  You might give those a 
try, as I know there were substantial changes to metadata stuff between 1.9.1 
and r355/trunk.

Test file attached.

I tried using mp4tags from r355, and that seems to be working fine. Thank you 
for the tip. :)

If it works in main, I'm going to mark this as closed.  Reopen it if you still 
have issues moving forward.  Thanks!
