 +To do a clean MPG [[dvd_copy|copy]] from a DVD:
 +
 +<​code>​
 +dvd_copy -o - | ffmpeg -i - -map 0:v -map 0:a -map 0:s -codec copy -f vob dvd_copy.mpg ​
 +</​code>​
 +
 +Or into Matroska:
 +
 +<​code>​
 +dvd_copy -o - | ffmpeg -fflags +genpts -i - -codec copy dvd_copy.mkv ​
 +</​code>​
 +
 +''​ffmpeg''​ can copy a Blu-ray directly as well, once you know the playlist number (see [[bluray_info]]).
 +
 +<​code>​
 +ffmepg -playlist 800 -i bluray:/​dev/​sr0 -codec copy bluray_playlist.mkv
 +</​code>​
 +
 +** Adding Chapters **
 +
 +  * See [[https://​ffmpeg.org/​ffmpeg-formats.html#​Metadata-1]]
 +
 +Create a file with the metadata. This example here has chapters at each minute mark.
 +
 +<​code>​
 +;​FFMETADATA1
 +[CHAPTER]
 +TIMEBASE=1/​1000
 +START=0
 +END=60000
 +title=Chapter 1
 +[CHAPTER]
 +TIMEBASE=1/​1000
 +START=60000
 +END=120000
 +title=Chapter 2
 +[CHAPTER]
 +TIMEBASE=1/​1000
 +START=120000
 +END=180000
 +title=Chapter 3
 +[CHAPTER]
 +TIMEBASE=1/​1000
 +START=180000
 +END=240000
 +title=Chapter 4
 +</​code>​
 +
 +Use the file as input with the encode, and map the metadata:
 +
 +<​code>​
 +ffmpeg -i video.mpg -i chapters.txt -map_metadata 1 video.mkv
 +</​code>​
 +
 +You can extract the metadata as well:
 +
 +<​code>​
 +ffmpeg -i dvd_copy.mkv -f ffmetadata metadata.txt
 +</​code>​
