dvpackager
Rewrap a DV stream. This script is part of the dvrescue project.
Usage:
dvpackager [options] file.dv
Options:
By default, dvpackager will split the output files so that each time
significant technical characteristics of the dv stream change (such as aspect
ratio, frame rate, audio channel count, or audio sample rate) a new output file
will be written. The following flags adjust the way dvpackager will split the
output.
-s (split the output file at recording start markers)
-d (split the output file at non-consecutive recording timestamps)
-t (split the output file at non-consecutive timecode values)
-o <dir> (provide a custom output directory)
-O <pattern>
(specify a pattern for output files. The following variables may be
used:
%FILENAME% - will use the filename of the input file without it's
extension
%RECDATE% - will use the recording date of the first output frame,
in YYYY-MM-DD format. If there is no embedded recording
date, then 'XXXX-XX-XX' will be used.
%RECTIME% - will use the recording date of the first output frame.
If there is no embedded recording date, then
'XX-XX-XX' will be used.
%TC% - will use the timecode value of the first frame or use
XX-XX-XX-XX if no timecode is stored in the first frame.
%PARTNO% - This is an incrementing number of the output starting
from 1.
The default pattern is "%FILENAME%_part%PARTNO%". The
extension of the output file is determined by the -e
setting.)
Note that if the output pattern would generate multiple output files
with the same name then a 3-digit incrementing number such as "-001"
will be added to the end of the filename.
-e <ext> (specify the extension of the container to use. Tested with:
mkv, mov, dv. Defaults to mov. Note that using the 'dv' option
shall simply extract the dv from the file while using the
selected options to split the output.)
-l <code>(specify the language code to use for the audio tracks.
If multiple languages are provided with a comma delimiter such as
'eng,spa,fra,nor' then they are used for each audio track in order.
Note that usually could be one or two stereo tracks, but if -m is
enabled then it is possible for two or four mono tracks, each
with it's own language code.)
-L <code>(specify the language code to use for the caption tracks (if
any).
-m (By default, audio will be handled in stereo pairs, enabling this
option will arrange the audio into tracks with mono channels.)
-S (embeds a caption track if there are captions to represent in the
source DV)
-Z (generate a DVRescue technical subtitle file, which contains
timecode and other frame-based metadata. This is an experimental
dvrescue subtitle format)
-n (do not repackage, simply generate a dvrescue xml if one doesn't
already exist, and report on what the output files would be)
-N <parts> (List the numbers of the segments that should not be packaged.
Multiple segments numbers may be listed as comma-delimited; for
instance "-N '1,3'" would output the 2nd segment and any segment
after the 3rd. Use "-n" to list the segments by number.)
-v (shows ffmpeg stderr output, otherwise this is hidden)
-z (disable colored terminal output)
-F <path> (provide a custom ffmpeg path)
-M <path> (provide a custom mediainfo path)
-D <path> (provide a custom dvrescue path)
-X <path> (provide a custom xmlstarlet path)
-x <path> (provide a custom path to a DVRescue XML that corresponds to the
input file)
-V <path> (provide a custom path to a DVRescue technical subtitle file that
corresponds to the input file, ignored if -S is not set)
-C <path> (provide a custom path to a DVRescue SCC that corresponds to the
input file, ignored if -S is not set)
Audio Resample Options
By default, dvpacakager will preserve the sampling rate of the input DV stream;
however, if the input contains a mixture of 32000 Hz and 48000 Hz audio, then
dvpackager will resample the packaged audio to 48000 Hz when muxing to a
container.
-3 (Enable this option to keep the sampling rate in its native format.
Setting this may result in more output files as each change in
sampling rate will require a new output file. Automatically enabled
when '-e dv'.)
-4 (Force all audio to be resampled to 48000 Hz.)
Aspect Ratio Options
-a <opt> (Choose a strategy for handling mid-stream changes in aspect ratio.
Options:
- n: Split segments for aspect ratio changes.
- 4: Do not split segments for aspect ratio changes alone,
and if packaging a mix of 4/3 and 16/9 content together,
then label it as 4/3 in the container.
- 9: Do not split segments for aspect ratio changes alone,
and if packaging a mix of 4/3 and 16/9 content together,
then label it as 16/9 in the container.
- c: Do not split segments for aspect ratio changes alone,
and if packaging a mix of 4/3 and 16/9 content together,
then label it according the more common aspect ratio in
that segment.
)
For example, the following command:
dvpackager -s INPUT.dv
will read -r INPUT.dv and rewrap those dv frames into an output file while making
one new output file whenever there is a change in significant technical
characteristics or frames with recording-start flags.
dvpackager also has an 'unpackage' mode
-u (export the dv stream from each provided file into a single dv stream)
For example, the following command:
dvpackager -u INPUT_1.mkv INPUT_2.mkv INPUT_3.mkv
will create one dv stream that contains all the DV of each input file.
dvpackager also has a method to express a table of how the file would be
repackaged given an XML input.
-T <xml> (provide only a table of information about the output files without
making any, provide the xml as an argument)
For example, the following command:
dvpackager -s -a c -T file.dv.dvrescue.xml file.dv
will show a table of the outputs for file.dv with the provided options (-s -a c).
