Very long time of parsing of tags (mp3, mp4, ...)

[Vladimir Skuzovatkin]

Hi!

I try to write "tag editor" with using "TagLib" library.
OS: Windows, library version number: TagLib 1.6.3.

I found next problem.
The file (mp3, mp4, ...) is opened for a long time (>30 sec) after writing
to it a image (attached picture, coverArt).

For example:
1) Small (~10Kb) PNG image was written into media file. Time of opening file
(after writing of image) is equal to ~4 milliseconds.
2) Small PNG image was deleted from media file and big (~400Kb) PNG image
was written into media file. Time of opening file is equal to ~30 seconds.

Why the time to open (to parse tags) is very big?
Can you reproduce this error?

Vladimir
