+ | 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> | ||

Also, MV1234.MP4 is the old supported format. My PSP (firmware >5) supports "movie.mp4" naming scheme, as well as folder structures just fine! | Also, MV1234.MP4 is the old supported format. My PSP (firmware >5) supports "movie.mp4" naming scheme, as well as folder structures just fine! | ||

- | ffmpeg seems to have issues creating MKV files. For one, they are much larger | ||
- | than an AVI with the same encoding options. Secondly, they dont' seem to work | ||
- | well when AC3 is placed in there. I'd recommend encoding to AVI (or MP4) and | ||
- | then using mkvmerge. |
