[FFmpeg-user] Naming chapters in Matroska video

[Ulf Zibis]

Hi,

This is the meta data from my original video:

;FFMETADATA1
SOURCE_TYPE=dvd
encoder=Lavf58.45.100
[CHAPTER]
TIMEBASE=1/1000000000
START=0
END=10911555556
[CHAPTER]
TIMEBASE=1/1000000000
START=10911555556
END=819225777778
[CHAPTER]
TIMEBASE=1/1000000000
START=819225777778
END=1839369955556
[CHAPTER]
TIMEBASE=1/1000000000
START=1839369955556
END=2689490133333
[CHAPTER]
TIMEBASE=1/1000000000
START=2689490133333
END=3289574977778
[CHAPTER]
TIMEBASE=1/1000000000
START=3289574977778
END=4584758088889
[CHAPTER]
TIMEBASE=1/1000000000
START=4584758088889
END=5516019688889

I've edited the file to (added chapter names):

;FFMETADATA1
SOURCE_TYPE=dvd
encoder=Lavf58.45.100
[CHAPTER]
TIMEBASE=1/1000000000
START=0
END=10911555556
[CHAPTER]
TIMEBASE=1/1000000000
START=10911555556
END=819225777778
title=1 - Intro
[CHAPTER]
TIMEBASE=1/1000000000
START=819225777778
END=1839369955556
title=2 - Restaurant
[CHAPTER]
TIMEBASE=1/1000000000
START=1839369955556
END=2689490133333
title=3 - At home
[.....]

After importing it to the video, with

ffmpeg -i INPUT.mkv -i INPUT.meta -map_metadata 1 -c copy -movflags +faststart OUTPUT.mkv

, ... I still don't see the named chapters.

How to correctly add chapter names?

Here the ffprobe output:
