Hi,
this version (see attachment) works for me. The original script not! :(
Debian/SID
digikam 0.8.1+0.8.2-rc1-1

# DESCRIPTION :
#
# IMAGES2MPG : convert images sequence on a MPEG files for create a VCD/SVCD/XVCD/DVD portfolio (with vcdimager)
#
# This script use this packages : 'ImageMagick' ver >= 5.4.8 [http://www.imagemagick.org/]
# 'MjpegTools' ver >= 1.6.0 [http://mjpeg.sourceforge.net/]
#
# You give the images files names on the command line (see the options '--help').
# The images formats must be reconized by ImageMagick program.
#
# This script used this externals binary programs :
#
# - 'montage' from ImageMagick for resize the images for the TV screen size.
# - 'composite' from ImageMagick for make the transition between images.
# - 'convert' from ImageMagick for convert the images before MPEG encoding.
# - 'identify' from ImageMagick for check the background image file size.
# - 'ppmtoy4m' from MjpegTools for create a video stream from the image.
# - 'yuvscaler' from MjpegTools for adapt the video stream size before MPEG encoding.
# - 'mpeg2enc' from MjpegTools for encode the video stream in MPEG file.
# - 'ogg123' from vorbis-utils to transcode an ogg-audio file to wav
# - 'mpg123' to transcode an mp3-audio file to wav
# - 'mp2enc' from MjpegTools to transcode a WAV sound file to a MP2 file.
# - 'mplex' from MjpegTools for multiplexe the MPEG file and the MP2 sound and convert
# the final MPEG file to a DVD/XVCD/SVCD/VCD format compatible with vcdimager program.
#
# You can use the 'KIPI' KDE frontend with this script. Look this URL : http://extragear.kde.org/apps/kipi
#
# Return value : 0 -> Process finish succefuly.
# 1 -> Error.

--with-gui : running with 'KIPI' KDE GUI frontend [see http://extragear.kde.org/apps/kipi].
-t <num> : enable transition between images with the speed [1=slow, 2, 4, 5, 10, 20=fast].
-T <Temporary folder> : use a specific folder for creating the temporary files (ex: '/tmp').
-f <Video format> : video format [DVD, XVCD=default, SVCD, VCD].
-n <Video type> : video type [PAL=default, NTSC, SECAM].
-b <background file> : 768x576 pixels background image file name [black color = default].
-c <RGB color> : hex RGB color for background image (ex: AA001F).
-d <num> : duration for each image in MPEG file [10s = default, 1s = mini].
-a <MP2 audio file> : MP2 audio file to merge with the video sequence.
-w <wav|ogg|mp3 audio file> : WAV/OGG/MP3 audio file to convert in MP2 and to merge with the video sequence.
-o <output MPEG file> : the ouput MPEG file name [temporary file name = default].
-i <input images files> : images files name to merge in MPEG.
-I <ImageMagick bin folder> : folder for ImageMagick binary programs.
-M <MjpegTools bin folder> : folder for MjpegTools binary programs.
-h | --help : this help.
The 'images2mpg' bash script convert some images on MPEG sequences with a specific
duration and merge all images on an single MPEG file. It use the 'MjpegTools' &
'ImageMagick' packages.
You can use this for to build some DVD/XVCD/SVCD/VCD portfolios for your home DVD player.
Use 'vcdimager' for create this...
Notes :
- The input images files with the '-i' option must be the last command line parameters.
- If you use some whitespaces in the path folders/files, use '"' around the complete path string.
Examples :
#./images2mpg -f SVCD -d 15 -w Music.wav -o MyPortfolio.mpg -i 01.jpg 02.jpg 03.jpg 04.jpg
Build PAL (default) SVCD MPEG file with the 'Music.wav' sound file and this image files sequence :
01.jpg
02.jpg
03.jpg
04.jpg
For each image on the portfolio, the screen show duration is 15 seconds. The output file
is 'MyPortfolio.mpg'. There isn't transition between images.
#./images2mpg -n NTSC -t 2 -o MyPortfolio.mpg -i *.png
Build XVCD (default) NTSC MPEG file with a transition between image (speed 2) and all
local PNG images files. The image files sequence use the local filesystem sort.
