Command-line tool to quickly create an FFMETA file for ffmpeg, mainly for building the chapter metadata from a CSV file.
Just clone and run yarn.
First, create a CSV file for the chapters. It should look like this:
title,startTime,endTime
Chapter 1,0:00:00,0:01:00
Chapter 2,0:01:00,0:05:00
The duplication is not required; you may omit endTime if the subsequent chapter has a startTime, and you may omit startTime if the previous chapter has an endTime.
After preparing the CSV file, run a command like the following:
$ ./cli --chapters ./data/chapters.csv --title "Test Video" --author "Video Tester"
;FFMETADATA1
title=Test Video
author=Video Tester
[CHAPTER]
TIMEBASE=1/1000
START=0
END=60000
title=Chapter 1
[CHAPTER]
TIMEBASE=1/1000
START=60000
END=300000
title=Chapter 2
