gallery2 and dvd-slideshow

g2s version 0.5.8 (I got sick of typing gallery2-to-slideshows )

g2s works through a complete site, including sub-albums, and produces multiple
slideshows with menus. The result is an XML definition file for dvdauthor, and
all the video objects needed to make a DVD.

Features include rotation of images, and autoplay.

Warning: crossfade is currently on by default, so generation of slideshows
could easily take SEVERAL HOURS depending on the size of your site.

Still a lot of bugs and unimplemented features... but produces nice DVDs easily.
"g2s -help" will explain just about everything.

Suggestions for improvement welcomed.

Marcus.

http://marcusbrutus.cust.internode.on.net/software/g2s-0.6.0.tar.gz

gallery2-to-dvd 0.6.3

New features include:
- random autoplay
- handle mpeg videos

Enjoy.

Marcus.

# Known Bugs 0.6.3
#	- images that aren't in leaf albums (albums without subalbums) are not
#	   included (feature?  )
#	- images in a leaf album that contain mpeg video(s) are not included.
#	- recycling needs more refinement ... strange errors grow without occasional
#	    flushing. This option is really only suitable for short rebuild
#	    runs with minor fixes, at this stage, so problem is not yet
#	    considered urgent. Probably cleaning/restoring g2s-old if break/bust
#	    detected would help.
#	- mpeg videos are assumed to be dvd ready for the video format used.
#
# Changelog 0.6.3
#	- fixed problematic custom thumbnail race condition
#	- improved selection of derivative images for highlight
#	- improved SQL error output
#	- added randomness to autoplay and changed title-jumping method
#	    (due to limit of 128 instructions per pgc)
#	- made duration of panoramic scrolling = aspectRatio * duration
#	- fixed logic for embedded highlight
#	- improved handling of mpeg videos
#	- fixed subtitle settings and added logic
#	- miscellaneous cleanups (inc. functions returning variables)

Thanks valiant!

#	- can not seem to use entry=subtitle and jump using subtitle button
#	    for brain-dead players like the PS2 (works in gxine).
#	    Option button included in root menu to compensate.
#
# Changelog 0.6.4
#	- added options menu system to change settings during playback

NOTE THAT ALL VERSIONS UP TO AND INCLUDING THIS ONE ONLY HANDLE MULTI-SITES
Version 0.6.5 will support single sites.
0.7.x development series is a complete redesign and will work on either at much higher speed.

I'd love to make it a module.

There are (probably) several issues involved.
The most important of which is that I'd like to rewrite all
the database lookup functions in php for speed and compatibility reasons.
(ie. using the g2 API rather than reverese-engineered command-line lookups)

To be honest, I had not envisaged having anyone other than the admistrator
generating DVDs, as with your suggestion ... unless the (majority of the)
slideshows had been pre-generated, it would take HOURS to produce a single
DVD (for a modest-sized site).
An email notification system could always be made I guess,
but the webserver would be flat out for a long time producing a DVD for
one customer, let alone many.

That being said, it shouldn't be too bad producing a few DVD images per day,
regenerating slideshows daily where required, and using the same slideshows
in different combinations (might be doubly painful for pal vs ntsc)
(features and content decided by the site admin)
and allowing them to be downloaded in the cart.

Food for thought.
Thanks for the suggestion.

Generation of the dvd itself is not the time consuming process,
nor the exploration of the g2 database, however should you skim through
the gallery2-to-dvd code you will see that there is much more involved
than just resizing and framing.

The majority of the time is spent generating the video object slideshows.
Multiply that time by 3 if crossfading between images (recommended effect).
This is done by dvd-slideshow (a bash script) written by Scott Dylewski,
and while it's conceivable that the process may be faster if the code was
written in (say) C, there are so many dependent programs (eg. ImageMagick)
that I can't say that I see a real benefit in doing so.

The sample site above has approx 60 titles made from over 400 images direct
from camera (4MP Canon A520). Generation of the slideshows for that takes
approx 6 hours at full (PAL) resolution on a P3/650 with adequate memory.
(The webserver is actually a virtual machine, but there's no need for details)
There are option(s) to produce lower resolution slideshows which should
significantly reduce generation time, however I have not enabled that
ability in gallery2-to-dvd yet.

I suspect that someone (like yourself?) is more likely to build the functionality
that you speak of into a program higher up the food chain.
At the moment, gallery2-to-dvd is simply a script that does what the name implies.
Packaging, pretty labels, prices, downloading and whatever all sound like
features of a "front-end" yet to be developed.

I appreciate your ideas, and I'm sure they will help shape future development.

Regards,

Marcus.

I have a "little" problem when trying to generate a DVD from my gallery2 install.

The name of the database where information are stored is "gallery2", and the tables in it are named like "g2_*", but the field names always begin with "g_*".
The result is that gallery2-to-dvd is unable to retrieve information from the database.
Here are some logs from the generated file "g2-g2s.log":

How can I bypass this problem?

I have not made anything to have this formatting issue, so I don't know how to solve it!

Can somebody help me?

Thanks!

Thanks for your answer!

First of all, I have a single-site install, as you correctly guessed.

I have made the modifications you wrote, and now gallery2-to-dvd is working without error statements!

But I have another problem now: when I type the next command ("dvdauthor"), I have this:

So what is the solution? I have run gallery2-to-dvd with the -n option but it did not do anything...

The file g2-dvdauthor.xml contains these lines:

Thanks for your help!

I have sent you an email with the content of the log and the g2s files.

Before sendong you the content of the log file, I did not noticed the 3 errors which occured. Always the problem with the "g_" beginning of the field names.

dvd-baker 0.7.29 (beta) has now been released after a complete rewrite.

Operation is now split into two parts:
- a php script on the G2 webserver creates a dvd recipe (dynamically)
- dvd-baker is a bash script capable of remote operation.

dvd-baker pulls the recipe from the website, and then all the listed ingredients.
The slideshows and menus are constructed, and linked together in a dvdauthor.xml file.
It can also (optionally) execute dvdauthor for you to construct the dvd filesystem.

Please see http://dvd-baker.sourceforge.net

Note: requires dvd-slideshow 0.7.3

There certainly are, however, I'd intended doing a few other things first:
- release 0.7.40 (any day now ) ... vastly improved structure and features
- make a php front-end (dvd-chef?) for editing recipes ... possibly to use as a basis for a g2 module
- possibly change the structure of the dvd itself to include titlesets
- make some of the dvd's I wrote dvd-baker for in the first place ;)

ie. I know a module would be nice, but it's not high enough on my list to register as important.

That being said, a very basic module may be released (with a bit of help) if it all
comes together before 0.7.40 feels ready.

Hi, ommma

Glad you got it going ... can you tell me what was wrong initially?

dvd-baker 0.7.35 is just about ready for release.
It was going to be called 0.7.40 ... but Oh well ;)
(I'm waiting for the official release of dvd-slideshow 0.7.5)
It includes two version of a g2 module (2.0 and 2.1)
The 2.1 version hasn't been fully tested, but then again, I haven't
received any complaints from the tasters yet ;)
0.7.35 is also about 6 times faster, and has many more features.

See http://dvd-baker.sf.net for more details.
You'll notice the website is ready for the updated version.

Hello,

I runned this test with the 400 Images and had no Problem, now I have this Vob, Bup and Ifo files. I opened them with my DVD Player on the Computer, and it works fine, but I am not able to burn them, or export them into an Iso file. As i don't have any DVD-Burner on my Linux Computer I have to use Windows. Which programm would you recomend to put this files into an iso (or other image file) or just burn them?

Thanks!

--EDIT--

As usual i found it out on my own, so i used mkisofs, and downloaded the file to my Computer and tried to burn it, but nero writes: Fals Disk for this file you have to Insert a CD not a DVD. I hope you have a solution before I find one

I have finally decided to bite the bullet and release.
dvd-baker 0.7.36 is available at http://dvd-baker.sf.net
The site includes compressed videos, pictures, samples,
and DETAILED manuals ;)

Most importantly, I've also released g2 modules for both
v2.0 and v2.1 galleries. They should be considered alpha.

Yes you DO have to install one of the modules to bake a g2 site.

I think my logic circuits probably burnt out some time ago. ;)
All the information about installing the g2 module is in the dvd-baker lib directory.
It's dawned on me now that the README, INSTALL and dvd-recipe modules (must rename them)
might be hard to find for a user who installs one of the distro packages (a recent invention).
I'll have a think about that for the next release.

The information you are looking for is most likely in /usr/lib/dvd-baker
The instructions are in INSTALL

There is no point in specifying '-i' (make iso) if mkisofs is not installed.

dir-dvd-recipe is a script in it's own right, but designed to be called by
dvd-baker with '-t dir' (which is the default anyway). There's no need to
use it directly.

I'll also improve the dependency checking logic when I can, and update the
version numbers.

Can you tell me which distro you're using?

ps. you might want to install mkisofs on your Linux machine, and then just
transfer the iso over for burning, rather than the whole DVD directory.

pps. the purpose of the samples is to verify that everything works correctly
before you start baking your own recipe.
Please try:

$ dvd-baker -d -e --sample 1

btw: your logfile shows that you specified an http source,
without a '-t g2' (sourcetype=g2) option.

OK, I'll have a look at the detail tomorrow (bed time now).
Would you please send gzipped versions of dvd-baker.log and slideshows/slideshow-1-1/dvd-slideshow.log
to

?
Log files clog up the forum here, and I find them hard to read.

Glad to hear you're running Debian
I'll be able to create a virtual machine to emulate yours very easily, if necessary.

Thanks for posting your results, made thing a lot easier.
I've released a new version for you on sf.net
Also included a new option '-L' that might interest you

Yes I did try to solve the problem(s) you had.
However, by the time I finished working on all the problems that I identified (4am), I had completely lost track of the original purpose. I did manage to bake a modified version of your recipe. (Nice pics)
If you would please post another tarball, I'll have another go, and this time I'll load your images onto a test account on my g2 webserver and do it properly.

Where is this message shown? Can you be more specific please?

Excellent, thanks for your trouble, however, I just discovered that sf.net mailing
lists have a 40KB limit (makes sense) so there's an email in the rejection mail that you can use.

*yawn*, hmmm
I've been working on this problem all day. (Without your tarball)
I've managed to add a new feature we'll call "intelligent diagnosis"
Got it working, just making the output look nicer.
This will help identify problems like permissions errors, module installation problems, etc.

If I fall asleep while you feel like playing, you might like to see if this works:

$ dvd-baker -d -e -u test2 -p test http://marcusbrutus.cust.internode.on.net/Kiah --debug 1

(I can't test it right now, but it WAS working ;) ... I've been forcing errors for my debug magic)
I'd love gzipped copies of login.html and dvd-baker.log from that test if you have time.
It *should* be an exact replica of your own test.

This sounds like a cool tool but having some difficulties.

As root I run

dvd-baker --get -t dir --force /var/www/localhost/g2data

[dvd-baker]     Recipe successfully retrieved
[dvd-baker]     Testing complete
[dvd-baker]     
[dvd-baker]     Done.

Then I run

dvd-baker --force recipe.txt

which produces:

[dvd-baker]     Baking progress: ln: creating symbolic link `/home/testme/Gallery2/DVD-baker/items/image_1.jpeg' to `/var/www/localhost/g2data/albums/2003_Summer_Vacation/Yellowstone/Dcp_1543.jpg': No such file or directory

It's right there is no such file because the actual file is named DCP_1543.JPG.
I then modify the recipe.txt to correct the filenames and run again but then I get:

[dvd-baker]     FATAL ERROR: Item does not exist: /home/testme/Gallery2/DVD-baker/items/_1.

So, is it me or does the script have some bugs?

marcusbrutus,

If I don't use --force then I get a version dependency failure for DVD-slideshow and the script aborts.
Logs posted to the user list.

Thanks!

hey Marcus,

Looks as though you solved the issues I had.
2 hours later and still bakin. No errors or faults so far.

Thanks!

It's still cookin... guess I have alot of images .
I don't think the progress bar works. All it does is output an "S" once every 30 minutes.
Baking Progress: SSSSSSSSS

Gotta get some sleep now so hopefully by tomorrow it will have completed successfully.

Right after I posted my above comment I noticed the CPU was railed to 100%.
I thought that was a bit excessive and then discovered I had two runaway processes.
I killed them and the cpu utilization went down to 50%.
My machine is a 1.7GHz Dual Xeon, 1GB ram.

The bad: DVD-baker aborted.

Error:
[dvd-baker] Baking progress: SSSSSSSSSSSSSSSSSSSSSSSSSSS
[dvd-baker] convert: /home/zman/Gallery2/DVD-baker/items/image_1784.tiff: unknown field with tag 37724 (0x935c) encountered. `TIFFReadDirectory'.
[dvd-baker] FATAL ERROR CONVERTING IMAGE
[dvd-baker] Image: "/home/zman/Gallery2/DVD-baker/items/image_2227.jpeg"
[dvd-baker] Aborting

This looks to be more of an IM convert issue vice DVD-baker.?
My guess is that windows/Photoshop is adding an extra 'meta-tag' to the TIFF image and IM does not understand these extra unknown tags.

I'm using Imagemagick v6.2.5.5. Viewing the source for IM tiff.h I find:
tag 37724 is private tag registered to Adobe for PhotoShop

I did in fact use Photoshop to create/edit my Tiff images.

According to some posts in the Imagemagick forums IM 6.2.6 fixes some of these tag errors.
So, maybe I'll try compiling and installing the newer version.
I'm determined to get this DVD-baker working on my system!

Thanks for your help.

Update: I upgraded to IM 6.2.6.0 and tried converting the tiff image to a png and jpg. The result was the same error but both the jpg/png image was in fact created and not corrupted. However, all the meta-tag info had been stripped out. The tiff in question here is 600dpi, 34MB.

Update2: I removed the offending Tiff images from the recipe... so here we go a bakin again.

Marcus,

I don't have problem with processes or anything like that now. After removing the Tiff images from recipe.txt DVD-baker proceeds along nicely but now I get the following error:

[dvd-baker] Baking progress: SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
[dvd-baker] parseRecipe FATAL ERROR: Item does not exist: /home/zman/Gallery2/DVD-baker/items/image_1372.jpeg
[dvd-baker] Aborted

The frustrating part is that each time I rerun DVD-baker with the recipe.txt it aborts on a different image.
The image does exist and the path is correct to the G2 album dir. The image_1372.jpeg does exist in the items dir.
Any idea what could be causing this issue?
