While using JAudioTagger 2.2.5 with this WMA file, i got that error:

Ive added test for to the code but isnt this a corrupt wma file, and therefore the exception thrown correct ?

[Sami32]

Actually i'll not call that "corrupt", but as i surprisingly discover that many softwares, as AudioShell, MP3Tag, TagScanner, are wrinting WMA cover incorrectly, so i take time to report it and letting you know.

That's said i was the first surprise when i discovered that while testing audio files.

[IJabz]

Do you understand what is wrong with it and why its not corrupt because I dont I rarely deal with wma files

[Sami32]

From what i understood, it's that since a video frame (MP43) was added to this WMA file, where it shouldn't, it fail to search farest than that, as it should not be there. So you are right, we can call that a corruption. Since i'm not used to WMA format either, here the specifications: http://go.microsoft.com/fwlink/p/?linkid=31334 http://web.archive.org/web/20120102100806/http://www.microsoft.com/downloads/info.aspx?na=41&srcfamilyid=56de5ee4-51ca-46c6-903b-97390ad14fea&srcdisplaylang=en&u=http%3a%2f%2fdownload.microsoft.com%2fdownload%2f8%2f0%2f5%2f80506BEB-C95A-47AE-99CF-0D6D6D028ABA%2fASF_Specification.pdf

As a side note, VLC will read the cover tag and many others players like MPC or PotPlayer will read the MP4 video frame.

EDIT: Or that could be because it's not a supported codec ?

Compression ID Specifies the type of the compression, using a four-character code. For ISO MPEG-4 video, this contains MP4S, mp4s, M4S2, or m4s2. In the Compression ID, the first character of the four-character code appears as the least-significant byte; for instance MP4S uses the Compression ID 0x5334504D. Defined as the biCompression field of a BITMAPINFOHEADER structure.
