Summary0007414: Synchronization gets stuck on certain files
DescriptionI'm not sure why this is the case, but synchronization seems to just get stuck on certain files.

i.e. synced ~ 6500 files, but then tracks in a particular directory just can't sync.

Note:
-Auto-conversion was not enabled
-Files were synced using Mass USB Plugin, with save AA to Tag enabled
-Files were just being synced to a portable drive
-Upon trying to sync again, sync would get stuck at file1 (the problematic file--see debug log)
-Upon deleting the problematic files synchronization worked as expected.

Log and problem files posted to server.
TagsNo tags attached.
Fixed in build1351

Note: when 'Save AA to Tag' is disabled, synchronization proceeds normally. Re-assigning to Ludek.

It freezes in ID3Lib when calling ID3Tag_UpdateByTagType, probably the images are too large (>4MB) to be written to ID3 tag. The same freeze appears when user tries to add the large JPG image to tag via Properties->Artwork.

By testing I found that 1MB large JPEG takes ~ 20 seconds when writing to ID3 tag.
4MB large JPEG seems to be endless.

I resolved this by auto-resizing large images to 256x256 px JPEG when writing to file tag during device sync.

Fixed in build 1351.

Note that you can still notice a 7 second delay, but this is because of the conversion of the 6 hi-res JPEGs to 256x256.

Reverted the changes, because the original problem of slow tagging is now resolved by fixing ID3Lib directly (0007431).

So all should work fast now without a need to resize large images.
