Is ffsubsync support auto adjust subtitle duration #152

Subtitles from opensubtitle normally have correct texts, but their timestamps are ofhen messed up. Partially because aegisub used by most fansubbers is not user-friendly on timestamps adjustment.

Is ffsubsync support auto crop/extend subtitle entry display duration base on data from speech detection?

This isn't supported currently. Unfortunately, the VAD isn't precise enough for this sort of fine adjustment to individual subtitles. Possible this could change after investigating the use of a more modern VAD (see #153) but I would be surprised if any VAD is accurate enough to support this use case.
