I found FFmpeg in the repository of Ubuntu 8.10, Will it be legal for usage in India, for production purpose?

If this is for personal use you probably shouldn't worry about it, but I am not a lawyer. You should first read FFmpeg License and Legal Considerations. Secondly, you should check if India has implemented software patents. Also, by default ffmpeg from the Ubuntu repositories has not been configured to use many non-free or restricted formats. You would have to manually install the "unstripped" ffmpeg libraries to enable encoding and decoding of these additional restricted formats.
If you enable restricted formats
license IS NOT GPL ... so *i think* you can't redistribute
that's is written when you compile ffmpeg.
