| Summary | 0007414: Synchronization gets stuck on certain files | ||||
| Description | I'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. | ||||
| Tags | No tags attached. | ||||
| Fixed in build | 1351 | ||||
|
|
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. |
