.SH DESCRIPTION
|
|
.LP
|
|
This program extracts specific parts from a Matroska file to other useful
|
|
formats. The first argument tells \fBmkvextract\fR what to extract. Currently
|
|
supported is the extraction of \fBtracks\fR, \fBtags\fR, \fBattachments\fR and
|
|
\fBchapters\fR.
|
|
The second argument is the name of the source file. It must be a Matroska file.
|
|
|
|
.LP
|
|
Command line syntax for the \fBtracks\fR extraction mode:
|
|
.TP
|
|
\fB\-c\fR \fIcharset\fR
|
|
Sets the charset to convert the next text subtitle track to. Only valid if the
|
|
next track ID targets a text subtitle track.
|
|
.TP
|
|
\fITID\fR:\fIoutname\fR
|
|
Causes extraction of the track with the ID \fITID\fR into the file
|
|
\fIoutname\fR if such a track exists in the source file. This option can be
|
|
given mutliple times. The track IDs are the same as the ones output by
|
|
\fBmkvmerge\fR's \fB--identify\fR option.
|
|
.TP
|
|
\fB\-v\fR, \fB\-\-verbose\fR
|
|

.TP
|
|
\fIAID\fR:\fIoutname\fR
|

Causes extraction of the attachment with the ID \fIAID\fR into the file
|
|
\fIoutname\fR if such an attachment exists in the source file. This option can
|
|
be given mutliple times. The attachment IDs are the same as the ones output by
|
|
\fBmkvmerge\fR's \fB--identify\fR option.
|
|
.TP
|
|
\fB\-v\fR, \fB\-\-verbose\fR

.SH NOTES
|
|
The decision about the output format is based on the track type, not on the
|
|
extension used for the output file name. The following track types are
|
|
supported at the moment:
|
|
.TP
|
|
V_MS/VFW/FOURCC
|
|
Fixed FPS video tracks with this CodecID are written to AVI files.
|
|
.TP
|
|
A_MPEG/L3, A_AC3
|
|
These will be extracted to raw MP3 and AC3 files.
|
|
.TP
|
|
A_PCM/INT/LIT
|
|
Raw PCM data will be written to a WAV file.
|
|
.TP
|
|
A_AAC/MPEG2/*
|
|
All MPEG2 AAC files will be written into an AAC file with ADTS headers before
|
|
each packet.
|
|
.TP
|
|
A_AAC/MPEG4/*
|
|
All MPEG4 AAC files will be written into an AAC file with ADTS headers before
|
|
each packet. The ADTS headers will not contain the deprecated emphasis field.
|
|
.TP
|
|
A_VORBIS
|
|
Vorbis audio will be written into an Ogg/Vorbis file.
|
|
.TP
|
|
S_TEXT/UTF8
|
|
Simple text subtitles will be written as SRT files.
|
|
.TP
|
|
S_TEXT/SSA, S_TEXT/ASS
|
|
SSA and ASS text subtitles will be written as SSA/ASS files respectively.
|
|
.LP
|
|
\fBTags\fR are converted to a XML format. This format is the same that
|
|
\fBmkvmerge\fR supports for reading tags.
|
|
.LP
|
|
\fBAttachments\fR are written to they output file as they are. No conversion
|
|
whatsoever is done.
|
|
.LP
|
|
\fBChapters\fR are converted to a XML format. This format is the same that
|
|
\fBmkvmerge\fR supports for reading chapters. \fBNOTE:\fR At the moment
|
|
\fBmkvmerge\fR does not yet support this format, but it will in the upcoming
|
|
release which will be in mid August.
|
|
|
|
|
|
.SH EXAMPLES
|
|
Let's assume you've made a Matroska file with one video track, two audio tracks
|
|
and two subtitle tracks, and you need the second audio track and the first
|
|
subtitle track. So first fire up \fBmkvmerge\fR with the \fB--identify\fR
|
|
option:
|
|
.LP
|
|
$ \fBmkvmerge -i movie.mkv\fR
|
|
.br
|
|
File 'movie.mkv': container: Matroska
|
|
.br
|
|
Track ID 1: video (V_MS/VFW/FOURCC, DIV3)
|
|
.br
|
|
Track ID 2: audio (A_MPEG/L3)
|
|
.br
|
|
Track ID 3: audio (A_VORBIS)
|
|
.br
|
|
Track ID 4: subtitles (S_TEXT/UTF8)
|
|
.br
|
|
Track ID 5: subtitles (S_TEXT/UTF8)
|
|
.LP
|
|
Now you can call \fBmkvmextract\fR like this:
|
|
.LP
|
|
$ \fBmkvextract tracks movie.mkv 3:audio.ogg 4:subtitles.srt\fR
