Adding a Table of Contents to Videos Using iiif-prezi3

Overview This is a memo on how to add a table of contents to videos using iiif-prezi3. Segment Detection We use Amazon Rekognition’s video segment detection. https://docs.aws.amazon.com/ja_jp/rekognition/latest/dg/segments.html Sample code is available at the following link. https://docs.aws.amazon.com/ja_jp/rekognition/latest/dg/segment-example.html Data Used We use “Prefectural News Volume 1” (Nagano Prefectural Library). https://www.ro-da.jp/shinshu-dcommons/library/02FT0102974177 Reflecting in the Manifest File We assume that a manifest file has already been created by referring to the following article. The following script adds a VTT file to the manifest file. f # c r | l o a m e s x s d d i p e e i o I f f i r i f t i l w m r a m p w r r c f o w r _ f o i a e d a a i a a a o u i e p C a t n t d n t t n n n r t t t r l d h i u _ i h h g g v p h u e i _ m f r s f d e e i l a s s i i s e r r } u f r z e m o a e n e e = o a _ _ d a s _ f n t n a a ) t o . n i n a p n s g s p t i t = b _ i t d a d n n _ p w 3 t n e i t m m t f e a d o f e i n y s e r g g p e r o : i n f a e " n c " l d p _ c x t = e i l e " " a n i u i f ( e = n n = { ( = = { = d e t o _ d a _ i t t ( t t m e m s i t s p = r " = a y n = = s s = b s d y h o e p p s a t M f ( s e a j f a T t = p t [ e f e e " p u ( u o t n _ a e s e l t s " m n a m a e i s s " g " l g : e = t m t r ( i j n s e l f h o { a g b a [ s n [ [ E { = .
