Dear Friends, Currently, I am looking for command to create Webvtt for my video by using FFFMPEG. The requirement is creating a webvtt file with preview-thumbnail for using as THEOPlayer (https://support.theoplayer.com/hc/en-us/articles/207460505-Preview-Thumbnails-in-1-X<https://support.theoplayer.com/hc/en-us/articles/207460505-Preview-Thumbnails-in-1-X>) Example: WEBVTT
00:00.000 --> 00:10.000 /thumbnails/thumbnail1.jpg 00:10.001 --> 00:20.000 /thumbnails/thumbnail2.jpg 00:20.001 --> 00:30.000 /thumbnails/thumbnail3.jpg What I did so far: 1. I get duration for video (Cause: requirement required 100 sections for each video) #Get duration of mp4 file need to generate thumbnail duration="$(ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 $video)" 1. Then, I creating thumbnail with duration above: #Create folder to store thumbnail if not exist. mkdir -p $BASEDIR/$filename #Create thumbnail with size 200:100 ffmpeg -i $video -filter:v scale=200:100:force_original_aspect_ratio=increase,crop=200:100,fps=100/$duration $BASEDIR/$filename/thumbnail%04d.png –benchmark Now, I was successful to create thumbnail as I wish, but for creating Webvtt, I still looking the document and googling with no sign. Please someone help to point me the correct way or suggestion.
