How to use ffmpeg to encode a file with possible error?

Question

I have a video file, which contains some error. The file is readable, but possible some blocks are wrong during some disk operation. So while playing the video, a few seconds will no be displayed correctly. Most media player will let me play this file without crash.

Now I want to use ffmpeg to encode the file into some other format. But the re-encode process is blocked by that error.

I want to know if there's anyway to let ffmpeg to ignore that error, just like the media players. It can just ignore/skip that few seconds, and continue working on the rest.

Solution

The simple solution I found, is to use the -ss option to skip the place that have errors.
