Perplexed: spumux or image problem?

2009-12-01T11:48:26Z

Hi at all,

Following an old message of Samantha Lane (Re: Perplexing problem with
spumux Date: 2005-04-29 04:07:16 GMT
<http://article.gmane.org/gmane.comp.multimedia.dvdauthor.user/3093/match=last+button+parameters>)

I'm working for several days to a very very simple dvd-menu with these
free software tools ;)

So, here are three images of a button

gm convert -depth 8 -colors 2 +antialias -size 720x576 density 75x80
xc:transparent menux1_normal.png
gm convert -size 720x576 -density 75x80 xc:transparent -colors 2
+antialias -fill none -stroke blue -strokewidth 1 \
-draw "rectangle 36,30 218,176" menux1_highlight.png
gm convert -size 720x576 -density 75x80 xc:transparent -colors 2
+antialias -fill none -stroke red -strokewidth 1 \
-draw "rectangle 36,30 218,176" menux1_select.png

and then a spumux.xml:

<subpictures>
<stream>
<spu
force="yes"
start="00:00:00.00"
image="menux1_normal.png"
select="menux1_select.png"
highlight="menux1_highlight.png">
<button name="1" x0="36" y0="30" x1="218" y1="176"/>
</spu>
</stream>
</subpictures>

When I run spumux it seems all OK:
[...]
INFO: Picture menux1_normal.png had 1 colors
INFO: Picture menux1_highlight.png had 2 colors
INFO: Picture menux1_select.png had 2 colors
INFO: Pickbuttongroups, success with 1 groups, useimg=1
INFO: Found EOF in .sub file.
INFO: Max_sub_size=470
INFO: 1 subtitles added, 0 subtitles skipped, stream: 32, offset: 0.12

Statistics:
- Processed 0 subtitles.
- The longest display line had -1 characters.
- The maximum number of displayed lines was 0.
- The normal display height of the font arial.ttf was 0.
- The bottom display height of the font arial.ttf was 0.
- The biggest subtitle box had 470 bytes.

But when I run dvdauthor I receive:
[...]
INFO: Creating menu for TOC

STAT: Processing menux6_final.mpg...
ERR: Cannot find button '2' as referenced by the subtitle

Running spuunmux, it seems to me that the program sees two bottons where
there is only one!
Here is sub.xml:
<subpictures>
<stream>
<spu highlight="sub00000h.png" select="sub00000s.png"
start="00:00:00.00" xoffset="36" yoffset="30" force="yes">
<button name="1" x0="36" y0="30" x1="218" y1="176" up="1"
down="1" left="1" right="1" />
</spu>
<spu highlight="sub00001h.png" select="sub00001s.png"
start="00:00:00.00" xoffset="26" yoffset="28" force="yes">
<button name="1" x0="36" y0="30" x1="218" y1="176" up="1"
down="1" left="1" right="1" />
</spu>
</stream>
</subpictures>

Is a problem of my XML file or - as I read in others various messages
the list - a problem with the RGBA channel in ImageMagick/GraphicsMagick?
How I can fix it?
I'm working with fedora 10 (kernel 2.6.27.38-170.2.113.fc10.x86_64),
ImageMagick 6.4.0 07/27/08 Q16 and GraphicsMagick 1.1.14 2008-06-05 Q8
on a AMD, on a machine with AMD Athlon(tm) 64 X2 Dual Core Processor 5200+

Thanks!

Safe Output Directory Deletion

2009-11-28T19:49:35Z

Reminder: if you want to delete an output directory created by
dvdauthor, use the dvddirdel script provided. This only deletes the
subdirectories and files that you would expect to find within a
DVD-Video directory structure, reporting errors if it finds anything
else. This helps to guard against accidentally deleting the wrong
directory, as is possible with “rm -rf”.

Having suffered more than one accident in this regard makes me
appreciate this sort of thing. :)

how to use existing mpeg2 files?

2009-11-25T03:44:14Z

Using qdvdauthor 2.0.0, I am building DVDs that are composed of multiple
mpeg2 files that were built by a Hauupauge PVR-500MCE capture card with
hardware mpeg2 compression.

The execution consists of, in part, such blocks as:

cmd> /usr/bin/ffmpeg -i
"/home/me/videos/emmett/geiger_30-way.mpg" -vn -acodec ac3 -ar 48000 -ab
224000 -y "/tmp/gsppt/geiger_30-way/geiger_30-way.ac3"

cmd> /usr/bin/ffmpeg -i
"/home/me/videos/emmett/geiger_30-way.mpg" -an -acodec copy -y
"/tmp/gsppt/geiger_30-way/geiger_30-way.m2v"

cmd> /usr/bin/ffmpeg -i "/tmp/gsppt/geiger_30-way/geiger_30-way.ac3" -i
"/tmp/gsppt/geiger_30-way/geiger_30-way.m2v" -aspect 4:3 -target
ntsc-dvd -ar 48000 -ab 224000 -y
"/tmp/gsppt/geiger_30-way/geiger_30-way.mpeg2"

Stripping the audio and video streams and then re-combining them causes a
very pixelated finished product, something totally undesirable.

I thought I could use the existing mpeg2 files with less processing as
follows:

cmd>
cmd>
cmd> /usr/bin/ffmpeg -i "/home/me/videos/emmett/geiger_30-way.mpg" -aspect
4:3 -target ntsc-dvd -ar 48000 -ab 224000 -y
"/tmp/gsppt/geiger_30-way/geiger_30-way.mpeg2"

Everything appears to continue processing normally, but I find that the
VTS_01_0.IFO is of zero size, as is the dvd.iso file.

Am I missing some necessary options to the ffmpeg command?

I did a variant of this patch that also returns a nonzero status if the
caption bits were previously set. This way you get an error if you try
to specify this more than once.

As usual, my version of the code is available here

New release DVDwizard 0.6.1 is out

2009-11-18T00:38:30Z

Hello,

the new release of DVDwizard version 0.6.1 is out.
This are the changes:

0.6.1 (2009-11-17)
-----
- Minimal version of ImageMagick defined to 6.3.5-0
- Second patch for ImageMagick 6.5.5.x
- Check valid duration time of video streams
- Solution for warning 'geometry does not contain image'
- Check for NTSC videos; check existance of screenshots
- Tested with transcode 1.1.5

Especially the checks with NTSC were my work the last days. From my
side all is o.k. for NTSC. But there are some bug messages. It would
be very nice that some other people could test the new DVDwizard with
original NTSC videos.

Ciao, Joo

Actually, both the original code and the patch are wrong. Casting an
actual argument to “const” is pointless. In fact, there is one
compilation warning because a const buffer is being passed to the second
argument of iconv(3), which is not declared as const (src/readxml.c,
line 268).

I have removed all this ICONV_CONST/ICONV_CAST business, and put in one
unconditional cast to fix the above warning.

Kind of. This gets complicated when you consider how it interacts with
interlacing.

Yes, well, maybe it's not so useful to treat the third number as part of
a ratio.

But those chroma samples are shared between the lines. So the value is
0.5, not 0. Unless you truncate it to an integer.

Per scan-line, not per line of chroma samples. To a first
approximation, the sample sites for 2x subsampling look like:

YCY YCY 4:2
Y Y Y Y :0

It's a ratio between:
- number of luma samples per line, l
- greatest number of chroma samples per line, c1
- least number of chroma samples per line, c2
usually scaled so the largest number is 4.

In practice c2 can either be equal to c1 (no vertical subsampling) or
zero (2x vertical subsampling).

As far as I understand the second number shows downsampling factor
horizontally (it is equal for both chroma). Third number shows nothing
real, just mapping to a particular schema (IMHO).

Multimedia Course Notes

2009-11-09T01:13:19Z

Been reading these online notes
<http://www.cs.cf.ac.uk/Dave/Multimedia/index_html> for a course on
multimedia. Just noticed on this page
<http://www.cs.cf.ac.uk/Dave/Multimedia/node136.html>, it says:

Using the traditional (and rather subjective) television measurement
of lines of horizontal resolution DVD can have 540 lines on a
standard TV (720/(4/3)) and 405 on a widescreen TV (720/(16/9)).

Actually, that’s wrong. The 4:3 factor is the “Kell factor”, it has
nothing to do with the aspect ratio of the screen. Thus the same 540
value applies to both narrowscreen and widescreen formats.

Not sure about the second problem, but as for the first one--do you have
a command in the FPC to jump to the first menu?

Players might do something automatically in the absence of this, but DVD
recorders probably won’t.

Hello all -

OK from the original development files, here is a copy of my final version
of dvdauthor-0.6.14-ivtv-patch-0.2

I think it is almost certainly the same as the one that Joo just posted,
but I did make a few tweaks in the final days. The attached is the
definitive final version.

thank heavens for backups...

Kind regards to all

PS - Although the MPEG headers are a bit intimidating to start with (I
find most of the specs almost impenetrable) it's well worth persevering,

Re: ivtv patches gone?

2009-11-08T13:02:00Z

Hi Joo -

That's my patch :-) thanks very much for keeping a local copy; I don't know
what happened to the copies I posted to the IVTV site (I'll check back in
the archive on my development machine in a minute or two, but I need to
reboot out of Vista and back into OpenBSD and I have couple of things I need
to finish first).

The version you have here is great, because I actually included some
comments (unlike me ;-) - but do you happen to know whether what you have
there is against 0.6.14 or 0.6.11 ? I had two different versions floating
around...

I'm so glad these patches helped a few people out.

Krgds, MartinC

I have found in my archives a version of the dvdauthor patch from 06/06/2008.

+/* NOTE TO THOSE UNFAMILIAR WITH MPEG FORMAT
+ * This code contains many 'magic numbers' related to analysing and
+ * and parsing MPEG data. MPEG content consists of a series of
+ * 2048 byte 'packs'. Each pack begins with a pack header that is
+ * identified by the byte sequence 00 00 01 BA. The rest of the pack
+ * contains other headers (each identified by their own start code),
+ * plus payload data and optional stuffing bytes. The headers contain
+ * data fields describing different aspect of the payload, timing etc.
+ * Frequently encountered types of header include:
+ * 00 00 01 BA : pack header;
+ * 00 00 01 BB : system header;
+ * 00 00 01 B3 : sequence header;
+ * 00 00 01 B5 : extension header;
+ * 00 00 01 B8 : group-of-pictures (GOP) header;
+ * 00 00 01 E0 : programme-elementary-stream (PES) header for first video channel
+ * etc...
+ * A useful quick reference for identifying and decoding MPEG headers
+ * is available at http://dvd.sourceforge.net/dvdinfo/mpeghdrs.html
+ * For detailed information try chapter 10 (p230) of 'digital video
+ * introduction to mpeg2' (Haskell, Puri and Netravali), which you can
+ * read online at http://books.google.com

Re: ivtv patches gone?

2009-11-08T11:45:39Z

Hi L and all

Thanks for pointing out that they have gone!

Next time I write some patches, I will know to post them in more than one
place :-)

I have just posted a copy of my patch to 0.6.14 (dvdvob.c) taken from an
archive site, but I'll go back to my development machine and make sure that
is the final version.

For reference, here also is a link to a copy of the earlier (and less
well-developed) version of the patch against 0.6.11 (it's in the first
attachment, at the bottom of the page).

Cheers MartinC

Re: Attempt to solve "ERR: SCR movesbackwards, remultiplex input."

2009-11-08T11:35:48Z

Here is a copy of my patch against version 0.6.14 (taken from
http://www.mail-archive.com/ivtv-users@.../msg08199.html):

The only file that needs to be patched is dvdvob.c

Re: Attempt to solve "ERR: SCR movesbackwards, remultiplex input."

Hi Lawrence -

I did quite a bit of work on this issue back in Jun 2008: see
http://www.mail-archive.com/ivtv-users@.../msg08234.html.
Unfortunately for some reason the source code of the patches themselves
seems to have vanished from that site, so I'll dig it out from archive and
sent it to you.

I was taking a lot of input from a hardware MPEG encoder card, that
triggered this problem *a lot*.

I wrote a bit about the causes of the issue here (see in particular "Part 2:
how to patch dvdauthor").

My post here:
http://old.nabble.com/Submission-of-proposed-patch-to-dvdauthor-0.6.14-(affects-dvdvob.c)-p17695878.html
explains a bit more what the patches are doing

The patches that I developed are probably a bit long in the tooth these days
(they are against version 0.6.14) but I think that they might be helpful for
you to have a look at.

One warning though: while I found that the DVDs produced via this patch work
absolutely fine with my players here (Sony, Denon), I have had reports from
some friends that they don't work in certain older kit.

Cheers - and good luck
MartinC

PS: for the benefit of the list, here is another document I wrote a while
ago, on the subject of how to use the Gimp to do anti-aliased menu text with
dvdauthor. It's well worth the effort!

ivtv patches gone?

2009-11-07T20:27:51Z

Hi folks.

Once upon a time there were dvdauthor patches posted at the
ivtvdriver.org wiki. I just searched for them
<http://ivtvdriver.org/index.php?title=Special%3ASearch&search=dvdauthor&fulltext=Search>,
and found a couple of hits, but they led to nonexistent pages.

Wonder what’s happened to these?

Re: QDvdAuthor and Qt4

2009-10-28T14:48:38Z

Not at the moment.

I believe there was a port at some point to OS/2 but since I coul not
install OS/2 on VirtualBox or VMWare I could not help out.

So you should be able to compile the application with the Qt 3.x devel
version and then QRender with Qt4.x

If I remember correctly the issue was on the backend side. That is you
need to have MPlayer in the path and accesible through the/a command
line interface. Can you use bash ?

If you want to invest the time and effort I am willing to help you out
getting it to a certain point. From there on it is mostly an
administrative project.

Question, do you have ffmpeg, or xine libs, or VLC or MPlayer available ?

How to input mpgs or audio/videostrams into Q-DVDauthor?

2009-10-03T07:02:22Z

Hi all,
I use Q-Dvdauthor 1.10 on a Suse 11.1 machine to make dvds with menus and chapters. My source files are recordings of an VDR (I use linvdr), which are processed by vdrsync.pl, either on the VDR itself or on my suse-desktop. vdrsync extracts audio (*.mpa and/or *.ac3) and video streams (*.mpv). Then comes multiplexing with mplex, and there is a mpg-video with suitable quality. The VDR makes this all in one when I click on "export as mpeg2", which leads to the same mpg-video. With two dvdauthor commands I create an ISO, which I can burn. So far so good.

But these DVDs have no chapters. And here comes the task of Q-DVDauthor.
I make some menu and define some chapters.
When I click on the "Create DVD"-button, I come to the command window. So I thought, because the multiplexing for DVDs is already done (mplex with option -f = 8 or 9), I skip the conversion process. But I get (in the dvdauthor display") "Wailting for the first VOBU".

What can I do to give ready multiplexed files to Q-DVDauthor? Or is there another way to process VDR recordings with Q-DVDauthor?

Thanks for helping,
Richard

No problem, actually I believe if you have this questions, other people
will too, so I will try to put up some more vids on Youtube to show how
to use the dialogs or how to create a slideshow etc. It all helps, now
if I only would have enough time to do all of this :)

QDVDAuthor: Slideshow rendering issue

2009-09-29T02:44:27Z

Hello
I have made progress since the response I got to my ffmpeg issue.
But, while attempting to create a slide-show using QDVDAuthor (instead of
QSlideshow like I was trying before,) sometimes the individual chapters will
just stop rendering. I can't remember for sure how many chapters were set to
render at once, but I changed the setting to "1" and tried again. I started the
slide-show over again, and started the rendering process, and then went to bed.
About eight hours later, only three out of twelve chapters had completed, and
one was stalled at about 41%.

Here is a screen-shot that will give you some idea about how many pictures are
in each chapter:

During the time that I thought QDVDAuthor was rendering my slide-show chapters,
nothing else was being done on this computer.

Right now, rendering only one chapter (the only reason it is rendering now is
because I right clicked on it and chose "Re-Render") this is what the resources
on our system look like:
http://www.afolkey2.net/~steve/QDVDAuthor-Screenshots-0009.jpg

As you can see, only one processor (this is a quad-core processor) is maxing out
at 100%. Also, only about 1.2GiB of memory (out of the 8 that are on this
system) is being used. So at least on the surface anyway, it's not like our
system is being over taxed :)

I am at a loss as to what might be the issue here. It was implied elsewhere in
this message, but for the sake of clarity, I will restate some relevant
statistics about our system:
1. Processor: Intel Xeon 2Ghz Quad-core
2. Memory: 4x2Gib, for a total of 8Gib.

I know that all four processors are used to their full capacity when I compile a
lot of different projects from source code all at the same time. This is with no
noticeable reduction in the usability of the system.

Thank you,
Steven P. Ulrick

P.S.: I really apologize for my last two question to this list. Some of the
information that you gave me I did need to know. But a lot of it you needed to
tell me because I was too lazy to look into it just a LITTLE bit further. So, I
apologize, and hope that I do not become a nuisance.

Re: QSlideshow: "ERROR during ffmpeg execution!"

2009-09-28T02:36:00Z

Steven,

now that you know how to use the dialog to add videos to your project
you should use the same dialog to add your slideshows to the project.

The QSlideshow dialog is the 'old' way of creating a slideshow. I
believe the dvd-slideshow script has an issue with one ffmpeg parameter.
It will also NOT allow you to add audio, and vids to your slideshow. So
hop on over to the new dialog.

Click on [Add / Organize Images ]. Basically for every slideshow you
want to create you add a Group and then drag the images and vids into
that group. Once you play a bit with the dialog you'll see that it is
very easy to create multiple slideshows with a lot of images / vids
embedded.

When you leave this dialog, your slideshows should start to render ( 2
at a time ) and you should see the thumbnail increase from 0% to 100%.

Under the hood it uses qrender ( which is part of QDVDAuthor ) to render
the slideshows. So you have to make sure qrender is in your path.

Hope that helps.

Varol :)

QSlideshow: "ERROR during ffmpeg execution!"

2009-09-28T01:49:09Z

Hello Everyone
While attempting to create a slideshow to burn to a DVD, QSlideshow exited with
the following error:
[dvd-slideshow] Creating ac3 audio...
[dvd-slideshow] ERROR during ffmpeg execution!
[dvd-slideshow] see /tmp/dvd-slideshow.log for details
[dvd-slideshow] cleanup...

Here is the entire output from the "Create Dialog":
http://www.afolkey2.net/~steve/QSlideshow-CreateDialogOutput-001.txt

And here is the entire output of "/tmp/dvd-slideshow.log":
http://www.afolkey2.net/~steve/dvd-slideshow-0001.log

The only thing I noticed was that the ffmpeg that was used is one that I compiled
from source. So, just for fun I commented that ffmpeg out of my path and tried
again. We will find out how that went in just a moment... The result was the
same.

I may have missed something stupid like I did in the last (resolved) issue that
I brought to your attention. But my unlearned eyes did not see anything helpful
in http://www.afolkey2.net/~steve/dvd-slideshow-0001.log

Your help is greatly appreciated.
