changed milestone to %Bugs paradize

changed the description

Taglib meta reader exiting empty()

Looks like taglib doesn't support .aac files

Does not but the mono C-sharp does. Trying to figure how everything works, as adding a FileTypeResolver for .aac isn't enough. (We should be able to just parse ID3, but it does not seem designed like this)

I can force taglib to parse aac files, but the issue is now it takes forever to ByteArray.decode() the 50MB picture.

*** Tag information for /tmp/DJB.aac
=== TPE1 (Lead performer(s)/Soloist(s)): DJ B
=== TIT2 (Title/songname/content description): Digitally Imported's 16th Anniversary Progressive Special (2015)
=== TCON (Content type): (52)
=== APIC (Attached picture): (Conver Art)[, 3]: image/jpeg, 50462708 bytes

decoding caused by unsynchronization bit, which is supposed to be only used by mpeg files

Synch decoding is broken. I can patch to enable tags on AAC, but that will be worse with the current file as it will freeze VLC. https://github.com/taglib/taglib/issues/718

Should be fixed with taglib trunk, or next stable release

Thanks for the work.

added Component::Build system: Contribs Status::not VLC labels and removed Component::Demuxers label

Do you know how the file was created? The APIC tag contains a slightly broken copy of the audio stream. Is it likely that more such files appear?
