SUMMARY (ver. %s):
Encodes a series of PNG or JPG images into an Ogg Theora
(.ogg) stream and is also capable of performing some simple image
enhacements using ImageMagick. The images and audio are assumed to
be in an uncompressed LiVES format, hence making this encoder
more suitable to be used within a LiVES plugin (but can also
be used directly on a LiVES temporary directory).
OPTIONS:
-h for help.
-V shows the version number.
-C check external program dependencies and exit.
-o out will save the video in file "out".
Default: "'type'_movie.ogg". See below for 'type'.
-p pre the encoder assumes that sound and images are named using
LiVES' conventions i.e. "audio" and "00000001.ext",
"00000002.ext"... where "ext" is either "jpg" or "png".
However, lives_theora_encoder3 will create temporary files
which can be saved for later use (for example, after
enhancing the images with "-e" , which may take a long
time). These temporary files will be named
"pre_00000001.ext", etc... where "pre" is either "eimg"
or "rimg" and will be kept if the "-k" option is used.
lives_theora_encoder3 can then be run over the enhanced images
only by selecting the appropriate prefix ("eimg" or
"rimg") here. See "-e" to see what each prefix means.
Default: "" (an empty string).
-d dir "dir" is the directory containing the source image
files. These must be of the form "00000001.ext" or
"pre_00000001.ext" as explained above.
Default: "."
-a aspect sets the aspect ratio of the resulting Theora file. This can be:
1 1:1 display
2 4:3 display
3 16:9 display
4 2.21:1 display
Default: "2"
-D delay* linearly delay the audio stream by "delay" ms.
Default: "0"
* = NOT IMPLEMENTED (YET?)
-q quiet operation, only complains on error.
-v be verbose.
-t type type of video created. The options here are:
"hi": a very high quality movie, suitable
for archiving images of 720x480.
"mh": medium-high quality movie, which still allows
to watch small videos (352x240 and below)
fullscreen.
"ml": medium-low quality movie, suitable for
most videos but in particular small videos
(352x240 and below) meant for online
distribution.
"lo": a low quality movie format. Enlarging
small videos will result in noticeable
artifacts. Good for distributing over slow
connections.
Default: "ml"
-e perform some simple filtering/enhancement to improve image
quality. The images created by using this option will be
stored in the directory specified by the "-w" option (or
"-d" if not present, see above) and each filename will be
prefixed with "eimg" (see "-p" above). Using this option will
take enormous amounts of disk space, and in reality does
not do anything that cannot be done within LiVES itself.
Using this option enables the following four:
-w dir "dir" is the working directory where the enhanced
images will be saved. Although these can all
co-exist with the original LiVES files it is
recommended you use a different directory. Note
that temporary files may take a huge amount of
space, perhaps twice as much as the LiVES files
themselves. If this directory does not exist is
will be created.
Default: same as "-d".
-k keep the temporary files, useful to experiment
with different encoding types without having
to repeatedly enhance the images (which can be
very time-consuming). See "-p" above.
-c geom in addition to enhancing the images, crop them
to the specified geometry e.g. "688x448+17+11".
Filename prefix remains "eimg". Note that the
dimensions of the images should both be multiples
of "16", otherwise some players may show artifacts
(such as garbage or green bars at the borders).
-r geom this will create a second set of images resulting
from resizing the images that have already been
enhanced and possibly cropped (if "-c" has been
specified). The geometry here is simple a new
image size e.g. "352x240!". This second set will have
filenames prefixed with the string "rimg" (see "-p"
above). Note that the dimensions of the images
should both be multiples of "16", otherwise some
players may show artifacts (such as garbage or
green bars at the borders).
-s sndfile name of the audio file. Can be either raw "audio" or
"[/path/to/]soundfile.wav".
Default: "audio" inside "dir" as specified by "-d".
-b sndrate sample rate of the sound file in Hertz.
Default: "44100".
-f fpscode frame-rate code. Acceptable values are:
1 - 24000.0/1001.0 (NTSC 3:2 pulldown converted FILM)
2 - 24.0 (NATIVE FILM)
3 - 25.0 (PAL/SECAM VIDEO / converted FILM)
4 - 30000.0/1001.0 (NTSC VIDEO)
5 - 30.0
6 - 50.0 (PAL FIELD RATE)
7 - 60000.0/1001.0 (NTSC FIELD RATE)
8 - 60.0
If the input value is a float (e.g. 5.0, 14.555, etc.)
the encoder will use that as frame rate.
Default: "4".
-L lv1file use the images stored in the LiVES file "lv1file" (e.g.
"movie.lv1"). Files will be extracted inside "dir" as
specified by "-d". Using this option allows to encode
a movie without having to restore it first with LiVES.
Note that the encoder will not delete the extracted
files after it has finished, this must be done manually
afterwards. If frame code/rate (-f) and/or sound rate (-b)
are not specified the defaults will be used (30000/1001 fps
and 44100 Hz). These, however, may not be correct, in which
case they should be specified explicitly. Furthermore, the
.lv1 audio (if present) is always assumed to have a sample
data size in 16-bit words with two channels, and to be signed
linear (this is usually the case, however). If any of these
latter parameters are incorrect the resulting file may be
corrupted and encoding will have to be done using LiVES.
firstframe first frame number. If less than eight digits long it will
be padded with zeroes e.g. 234 -> 00000234. A prefix can
be added using the "-p" option.
Default: "00000001"
lastframe last frame number, padded with zeroes if necessary, prefix
set by "-p".
Default: the last frame of its type in the "-d" directory,
where "type" is set by the prefix.
Note that either no frames or both first and last frames must be specified.
EXAMPLES:
Suppose you have restored a LiVES' .lv1 file (in either JPG or PNG format),
and that the images are stored in the directory "/tmp/livestmp/991319584/".
In this example the movie is assumed to be 16:9. Then, in order to create
an ogg file you can simply do the following:
lives_theora_encoder3 -d /tmp/livestmp/991319584 -o /movies/default.ogg -a 3
and the clip "default.ogg" will be created in "/movies/" with the correct
aspect ratio.
Suppose we want to make a downloadable version of the clip, small in size
but of good quality. The following command activates the generic enhancement
filter and resizes the images to "352x240". Note that these operations
are performed after cropping the originals a bit (using "704x464+5+6").
This is done because we are assuming that there is a black border around
the original pictures which we want to get rid of (this might distort the
images somewhat, so be careful about cropping/resizing, and remember to
use dimensions which are multiples of 16):
lives_theora_encoder3 -v -d /tmp/livestmp/991319584 -w /tmp/tmpogg \\
-o /movies/download.ogg -a 3 -k -e -c "704x464+5+6" -r "352x240"
Since we use the "-k" flag the enhanced images are kept (both full-size
crops and the resized ones) in "/tmp/tmpogg". Beware that this may consume
a lot of disk space (about 10x as much as the originals). The reason we
keep them is because the above may take quite a long time and we may want
to re-use the enhanced images. So, for example, creating a high-quality
clip at full size can be accomplished now as follows:
lives_theora_encoder3 -d /tmp/tmpogg -t hi -o /movies/archive.ogg \\
-s /tmp/livestmp/991319584/audio -a 3 -k -p eimg
If, for example, we only want to encode frames 100 to 150 we can run
the following:
lives_theora_encoder3 -v -d /tmp/tmpogg -o /movies/selection.ogg \\
-a 3 -k -p eimg 100 150
Note that no audio has been selected ("-s"). This is because
lives_theora_encoder3 cannot trim the audio to the appropriate length.
You would need to use LiVES to do this.
To delete all the enhanced images you can just remove "/tmp/tmpogg".
If you notice that the video and audio become out of sync so that
near the end of the movie the video trails the audio by, say, 0.2s,
you can use the "-D" option as follows:
lives_theora_encoder3 -d /tmp/livestmp/991319584 -o test.ogg -D 200
Note that negative time values are also allowed ("-D" NOT IMPLEMENTED YET).
Suppose that you have "movie1.lv1", "movie2.lv1" and "movie3.lv1".
Batch-encoding can be done as follows (zsh-syntax):
for i in movie?.lv1
do
mkdir /tmp/$i:r
lives_theora_encoder3 -d /tmp/$i:r -o /tmp/$i:r.ogg -L $i
rm -rf /tmp/$i:r
done
This will generate the files "movie1.ogg", "movie2.ogg" and
"movie3.ogg" in "/tmp". Note that is is not necessary to
specify whether the files are stored in JPG or PNG format,
and that potentially time-consuming options (e.g. "-e") may
be enabled. It is not necessary to have a working LiVES
installation to encode .lv1 files.

CHANGELOG:
25 Sep 2004 : 0.0.1 : first release.
01 Oct 2004 : 0.0.2 : made all fps fractions.
13 Oct 2004 : 0.0.3 : fix aspect ratio by using
pixel aspect ratio instead of
frame aspect ratio (j@v2v.cc).
calculate frame size to do the above.
fixed extension from ".ogv" to ".ogg".
14 Oct 2004 : 0.0.4 : "size" is (width, height) (original
patch had assumed it switched).
26 Oct 2004 : 0.0.5 : can handle arbitrary fps values.
02 Nov 2004 : 0.0.6 : tweaked encoding quality levels.
08 Nov 2004 : 0.0.7 : make sure that the enhanced
color depth is 8-bits/channel.
tweaked encoding quality levels.
02 Jan 2005 : 0.0.8 : updated docs.
added sound rate (-b) option.
22 Jan 2005 : 0.0.9 : fixed stream.yuv fps calculation.
11 Feb 2005 : 0.1.0 : fixed aspect ratio error (my bad :( )
26 Mar 2005 : 0.1.1 : use env python (hopefully >= 2.3).
replace denoise3d with hqdn3d.
24 Aug 2005 : 0.1.2 : fine-tune mplayer filters (thanks to
zikzak@tele2.fr).
Fixed 2.21:1 aspect ratio.
09 Mar 2006 : 0.1.3 : added '-depth 8' to resize, as ImageMagick
keeps changing its damn behaviour.
02 Apr 2006 : 0.1.4 : small aspect ratio bug fixed.
tweaked audio quality settings.
28 Jun 2007 : 0.1.5 : handles paths with spaces appropriately
(thanks Gabriel).
