No error reported for bad index

Postby EricOuellet » Tue Feb 09, 2016 1:42 am


I'm not a professional in video. I used FFmpeg to detect errors in files for the ones where vlc would warn me. I'm using the latest version: N-78335-g9ee4c89 Copyright (c) 2000-2016.

VideoLan (VLC) error: "Because this AVI file index is broken or missing, seeking will not work correctly. VLC won't repair your file but can temporary fix this problem by building an index in memory. This step..."

I run this command on my video file to detect error: ffmpeg -err_detect aggressive -loglevel warning -i "myVideo.avi" -f null - >error.log 2>&1

But the log file stay empty. I try many options, verbose, info, etc, without success. Each time no error are detected.

I wonder why FFmpeg does not see any error when VLC find so important to warn people of it? Is that a bug in FFmpeg or simply VLC that is too sensible?

Should I ask for a suggestion?
