Originally created by @AdrianChandra on GitHub (Oct 19, 2025).

I have searched the existing issues, both open and closed, to make sure this is not a duplicate report.

The bug

When i run Refresh thumbnails an an AVI files the log show ffmpeg error (log in the relevant log output)

I try troubleshooting by removing 'reverse' on the -vf and it run sucessfully:

root@immich_server:/usr/src/app# /usr/bin/ffmpeg -skip_frame nointra -sws_flags accurate_rnd+full_chroma_int -i "/mnt/wdmycloud3000/Public/Backup/personal_sorted/2007-12-21/NURI_4D_14_A (2).avi" -y -fps_mode vfr -frames:v 1 -update 1 -v verbose -vf "fps=12:start_time=0:eof_action=pass:round=down,thumbnail=12,select=gt(scene,0.1)-eq(prev_selected_n,n)+isnan(prev_selected_n)+gt(n,20),trim=end_frame=2,format=yuv420p" tes.jpeg

Is there a possibility for me to change the ffmpeg parameter for the thumbnail generation?

I'm interested in this as it may be related to my problem. However, I have a thumbnail, and I have no errors in the logs. But AVIs simply do not play. I'll continue searching the issues and I'll submit my own if necessary.
