I decided to use Audacity to shorten the ac3 file from 6 seconds.
When exporting the modified file in ac3, Audacity claimed to use ffmpeg. There weren't any crash, so I suppose ffmpeg isn't the problem. But I'm not sure which ffmpeg is used here...
So I tried with this shorten ac3 file but the encoding failed the same way.
As you warned me, the length is not the problem, but I had nothing else to do, so it worthed the try.
