Crash: Auto-Tag causes Access Violation On Video Files [#22053.]

Post by mrevile »

I have encountered a consistent crash when using Auto-Tag on video files.

Steps to reproduce:

1. Right-click a video file (e.g. MKV) and select "Auto-Tag from Web"
2. Ensure the file name is clean and recognizable (e.g. "Shazam (2019)")
3. Let MediaMonkey populate metadata and artwork automatically
4. Do NOT manually change or select a different image
5. Click "Save"

Result:
MediaMonkey crashes with the following error:
"Application thrown an exception: Access violation at address ... in module 'MediaMonkeyEngine.exe'"

Important observations:
- If the file is NOT recognized (unclean filename), no crash occurs
- If I manually select an artwork image before saving, the crash does NOT occur
- The crash only happens when the default auto-selected artwork is left unchanged

This suggests the default artwork object may not be fully initialized or validated before being written.

Environment:
- MediaMonkey version: 2024.2.1.3213 Gold Lifetime
- OS: Windows 11
- File type: MKV

This issue is reproducible 100% of the time under the conditions above.

Please let me know if logs or additional testing would be helpful.

Re: Crash: Auto-Tag causes Access Violation when saving without modifying default artwork

I'm unable to reproduce this. Please capture this issue in a debug log (step 4b) and attach the log to a Support Ticket: https://www.mediamonkey.com/forum/viewtopic.php?t=86643

This will help a developer analyze why this happens on your setup.
