Pre-loading conditional content(pictures etc.) before it needed.

Hi, i have some linkedlist or tree-structure contents(images,sounds etc.) I want to pre-load next items(content) to cache while user interacting with current content. Thus, when user want to see next content, it'll show immideately and start loading next content in the background.
For an example,
Assume in image gallery in the tree structure. While user looking at the picture, i want to load next nodes of tree silently to improve speed.
Is it possible to do that? Or Any of you have suggestions?

Well of course i don't know exactly what the user will pick for next. But i know there are just couple of content he/she can choose from the tree structure.
Assuming next node consist 5 pictures. I want to start loading all simultaniously, so no matter what user choose, so whatever user choose, that content has %x percentence loaded. I'm also quite sure about there'll max 5 content in the next nodes.
For the future i'll collect data from user behaviour then i'll have possibility table to lookup and assign priorities for load.

Photoshop CS6 content (pictures, etc) will not display (or only partually) on the stage.

I just purchased and loaded Photoshop CS6. Pictures (actually this is for all content in any layers) will not display at all or only partually display (see picture below). I uninstalled and reinstalled the program but there is no change. The other Adobe products from the Master Suite Collection run fine (Flash, Encoder, etc). I am thinking that my instalation disc may be corrupted. Can you give me any advice?

Most likely the video card driver. Update it in GPU makers website. Need make and model of video card.

Lag after pre-loader hits 60% and before movie starts playing.

Hi all,
I’m hoping somebody can shed some light on an issue
that I’m experiencing with a Captivate project I’m
working on. I’ll try to explain this in detail so you
understand the background and scope of this project. These are
being exported as HTML/SWF and being viewed within IE6.
I’ve been tasked with taking a new employee training
course that is currently handled by a live person standing in front
of a room of people and showing them an 18 minute VHS tape and also
covering information that is presented on a PowerPoint file, and
making it into a Captivate movie.
I was able to get the original digital video cut into 4
chunks and converted to SWF by media group that produced the tape.
The four SWF files are 320x240 and range from 13 to 22 megs.
Because of the size of the files and the amount of content, I
created 8 ‘modules’ that make up the larger project.
The last slide of the first module launches the 2nd module, etc.
until the user has seen all of the modules which on their side
(other than a brief pre-loader popping up at times) is mostly
transparent and they think they are just watching a 30 minute
training course.
Basically, what I’ve done is laid out the modules so
that the whole course alternates back and forth between text slides
with voice-overs and the movie clips. The movie clip SWF’s
have been embedded into every other module, so:
Module 1: Intro to the course (text & voice-overs)
Module 2: Video clip 1
Module 3: Discussion about stuff (text & voice-overs)
Module 4: Video clip 2
Module 5: Discussion about stuff (text & voice-overs)
Module 6: Video clip 3
Module 7: Discussion about stuff (text & voice-overs)
Module 8: Video clip 4 and wrap-up
Now here is the problem:
We have 20+ offices and I am located at the main office where
the web servers are located. If I run through this, everything
works great. I tested this in one of our off-site locations today
where they have a semi-fast connection, but still going across a
WAN.
Module 1 loads fine. Hits 60%, plays, user can click Next,
Next, Next to proceed through the training. At the end of Module 1,
we prompt them with some text to let them know there may be a brief
delay before they see the upcoming video clip. Click Next, loads
Module2.swf which has the videoclip1.swf embedded in it (21 megs).
Takes a little while to load which is expected. Hits 60%.
Preloader goes away and then just white screen for at least 10
seconds (sometimes 20-30 seconds, depending on the size of the
embedded movie clip) before the movie actually starts playing.
This is not acceptable as the user will think that something is
broken. If the movie is not completely loaded, then it
shouldn’t have hit 60% and the preloader graphic disappear,
right?
I think that the problem revolves around the movie clip not
being able to play until it is fully loaded, although the Module
has loaded the 60% that it needs to begin playing. The only way
around this that I see is re-arrange my slides so that the video
clip is not the first slide to play in any given module.
We tried this on at least 7 computers, all of which were just
rolled out new last fall, so the machines are definitely beefy
enough to handle this.
Any ideas?
Thanks,
Mike

Nope, I am not being a wise guy, but I know it's possible to
have so much "weight" in the content of the last 40% that
additional delay might be required while a (early) required element
or object completes down-streaming. Just a thought...
Hi Larry,
Good to see you back on the forums and thanks for the reply.
What you posted further proves my point. From what I've been taught
about Captivate, it loads to 60% and begins to play while the
remaining 40% loads. Not loads to 60% and then some portion of the
remaining 40% may or may not have to load before it starts. If
that's the case, why not just load 100% before it starts and then
have no problems?
It shouldn't matter how large the file is, right? The only
difference is that larger files would take longer to reach the 60%
mark. 60% is 60% is 60%. Compare a feather to a car. 60% of the
weight of each item is still 60%, it doesn't matter how much it
weighs.
60% of a cubic foot of rock is the same percentage
as 60% of a cubic foot of marshmallows.
Anyway, I think the solution here is to fudge the problem by
putting a few 'less weighty' slides in front of the slide with the
embedded video so that the user has something to look at other than
a blank screen. I was just hoping somebody else might have
experience this and had a magic button I could press to make it all
better.
I could handle this if the preloader continued running so the
user had some clue that it was still working, but when the
preloader hits 60% and disappears and then nothing happens for
another 10-20 seconds, that's a problem.

But not sure how to do that. When I open iTunes it has a button that say "Back Up iPhone", but I'm not sure what that does. When I go into the sync options it say I have another user account and asks me if I want to merge of replace. I'm assuming it's trying to tell me I have an older iTunes Library, but don't know that. Geez, maybe people over 60 shouldn't have iPhones, iTunes just bafles me.

Pre-load form values before create a new Support Request

We are trying to send some values to the CRM from our system, So a User just need to click a button and He will see the CRM with some pre-loaded values, and then he will create the case after completing other fields.
Is possible to send POST - GET values?
Any suggestion?
Thanks

The values are dynamic, so is not possible to use always the same default values.
Right now we are creating the cases using a web service when someone clic on a link. The main problem here is that our users doesn't complete all the fieds and they close their window. so we have a lot of "cases" created without the entire information. That's why i'm looking a way to complete a form without using a web service (because it creates the cases)

Apple TV and Home Sharing "An error occurred loading this content"

Recently I moved and switched my homeshare library from my Mac to a Window8 PC. I'm running the same network equipent, but the bandwidth to the internet was less in the new place then the old one so I wanted to store more on the PC. My bandwidth to the internet is slow at times so I like to download to my PC and watch the shows on my appletv. I thought it might be a Windows 8 issue, but I powered up my Mac Pro (2008) again and it has the same problem. I thought it might be a WIFI issue so I ran network wires, same issue. The only new thing I can think that happened was the apple tvs recently took a SW update, I'm not sure what version they had before. (tend not too look at versions when things are working).
What I know:
All the shows play fine when I stream. (they can just take a 5-10m to start due to internet bandwidth, but they play fine).
Some shows play fine with homesharing (I have found no common thread between ones that do and don't).
All shows play fine on my PC in iTunes
Between my 2 AppleTvs (both running version 6.1) It is consistent which shows will play in home sharing and which will not. There have been a couple shows that will play on one but not the other and a couple shows that won't play one day but will the next day.
I have tried playing a show that will not play over and over for 10m. The status remains the same.
If the show has an option to resume playing or start from beginning. I'll be asked "Resume/Start over" first then be told "An error occurred loading this content"
The first time I try and play a show it takes 5-10 seconds to give me an error, repeat attempts typically take < 1 second to show the error.
Most shows on both my AppleTVs with home sharing return an error "An error occurred loading this content". I've tried running network wires, rebooting, holding menu and shift down to reboot, pulling power. I have examined the files that play versus ones that do not and they all appear to be in good working order. As an example. Episode 1, Season 2 of Big bang theroy plays fine, but Eposodes 2-5 don't, but then Episodes 6-8 do play ok. I find the same problem with Movies and Music Videos.
Setup Facts:
Asus Wireless Router is connected to my DSL modem into the Ausus router WAN port. The ASUS router creates a network 192.168.1.X my DSL has a 192.168.0.1 IP address.
On the AppleTV it has a valid IP address and I'm fairly confident the network is ok since I have NO issues streaming any shows from the internet via Music, TV shows, Movies, Hulu, Netflicks, etc.
PC is running Windows 8 and I've disabled all power reduction settings to be always ON. (Again some shows play fine, the ones that play seem to always play). Running itunes version 11.1.5.5
All the shows are ones I've downloaded iTunes. None of the shows are handbraked home videos.
AppleTV version 6.1 for both AppleTVs.
What I've tried:
Power Clearing Devices
Switching locations of Apple TV with different TVs
Trying Mac Pro and Windows 8 Home Shares
WiFi and networked
Changing HDMI Cables.
Every TV I have, 1: Sony (new), 1 LG (about 2 yers old), 1 Samsung (about 5 years old).
Any Adivce?

I have it working now.. BUT I still don't have 100% on both appleTVs. I'd guess it's closer to 99% (which is a huge improvement).
What I've done since:
First I verified that I had open on my firewall the correct ports. I use AVG Internet security so verified I had it setup ok. (this was after I tried a few times with it off). (this produced no improvement)
TCP
direction both ways
local ports 3689
remove port(s): all
remote addresses:all
UDP
direction both ways
local ports 5353
remove port(s): all
remote addresses:all
Might have been over kill, but I assigned both AppleTVs a fixed IP 192.168.0.200 and 201. by their MAC address on my router. I then added them to the whitelist in AVG Internet Security
I saved changes and rebooted my PC, AppleTVs and PCs
It still didn't work. (I described the above because when I tried removing them no shows played, so more an FYI if 100% of your shows don't play).
I then downloaded itunes (11.5) same version I was running.
I used 7-zip (winrar should work too) to unzip the file iTunes64Setup.exe into a folder iTunes64Setup. This is important, which I'll explain in the next steps.
I then ran the iTunes64Setup.exe and selected repair.
it then told me it could not find iTunes64.msi. which I gave it the directory iTunes64Setup that I had expanded the iTunes64Setup.exe into that directory. (Really apple??? This one anoyed me that it was in the EXE but I had to manually expand it and put it somewhere for you to refind )
It completed the setup and I rebooted my PCs and AppleTVs again.
I went to a show that was consistently not playing and it worked on both TVs. I'd say 99% are working fine now. What's special about the remaining shows I do not know. If the file was corrupt I would not expect to be able to play it on another appletv.
The few files that don't play:
I'm now convienced that my network is fine. with 99% playing ok. If it was an intermitent problem with the network I'd expect that re-attempts to play the shows would produce different outcomes.
What have I tried:
I've done a factory reinstall of the appleTV. (my advise is don't waste you time, it did nothing except eat up 30m of my time watching redownload and then entering passwords).
I've tried deleting the shows that don't play (which do play on my computer) and redownloading them (same outcome) (again, my advice would be don't waste your time). When I did a check of the files they redownloaded identically with only the creation dates different.
Open to move things to try. Any ideas anyone?

Dual boot Win7 pre-loaded and XP

I have a T510 that came pre-loaded with Win7 Professional. I'd like to dual boot with XP that I have loaded on a different hard drive on the same T510.
I do have the recovery disks. I can't do a fresh install of XP because it have over 300 programs installed. Is there some way to run the recovery disks with Win7 Pro to not format the XP partition. Can I make the XP partition read only and then run the recovery disks?
Maybe someone knows of a way to install the recovery disks, then ( I know how to move Win7 and make a partition before Win7 then restore XP to the hard drive) then repair Win7 so it has the correct drive letters.
Thanks,
Docfxit

What setup/programs will you be missing? I run a vanilla WIn 7 Pro 64 on my T400 and used TVSU to pull down everything that I need.
It may be that some multimedia stuff will be missing, but grab the installers for them from your Lenovo Win 7 setup before wiping it or removing that drive. Probably in C:\SWTOOLS (at least they were there in the old days. I don't have a Lenovo '7 load to examine.)
I'd probably do something like this, since I can't resist messing with a multiboot machine: clone the XP install to a large HD - or use the one you have if it 's big enough. Shrink the XP C: partition with your favorite tool. Fire up a MS '7 install DVD and install into the free space. I'm told you can use the Win 7 activation code that came w/your machine, but you may have to call MS.
Install TVSU for Win 7 and let it pull down the rest. Come to think of it, that's what I did with my XP T61.

Flash cs4 mac - Error opening URL '/:Users:someting.swf' - Not a "loading external content" problem

Hello.
I am having a weird problem when trying to test a movie or publish preview -> flash on mac with Leopard os.
The result is a blank movie with the usuall "movie not loaded" if u right click on it and the output returns the "Error opening URL 'the path of the swf here'.
This has nothing to do with loading external files or something like that. It happens even in blank movies and it gives the same error if I try to open a swf from flash ide.
I can publish the project or export the movie with no problem at all.
I can preview the movie in html. I can run all the swf files in my hard disk, network, usb stick, dvd etc., but when I try to open any of these files from flash ide I got that stupid error.
Its not something that stops me from working in flash ide but its slow to export movie any time I want to test it.
Things that I've tried so far but nothing worked:
Update the flash cs4 to the latest version
Update the flash players
Restored the release flash player as default player (I am using as default the debug player)
Cleared the preferences
Move the flash cs4 folder to another location in hd
Saved the fla document first before testing the movie (in different places with or without spaces in document name or folder)
Give read & write permissions for everyone for flash.app, players and for fla files when saved first before test movie
Unistall and install the application 3-4 times.
Test every as version just in case.
Also I've checked the folders when testing movie and I can see that it creates an swf file, which I can run it outside flash ide (the one that the flash ide player cannot load) with no problem.
The mac os has the default set up as it came. Nothing chnaged in permissions or security settings.
Thanx in advance.

In this particular example I am using this code to start the
xml file load:
// now load the XML file that contains the content strings
var sXMLFile:String = "xml/home.xml";
var xmlContent:XML = new XML();
xmlContent.ignoreWhite = true;
xmlContent.onLoad = onXMLLoadComplete;
xmlContent.load( sXMLFile );
But I don’t think the code is the problem here . This
happens on every file I load when I am using a relative path to the
content, regardless of how I load the content (XML object,
loadMovie, MovieClipLoader, etc…) and the same code executes
perfectly on every other machine in the office(Mac and PC).
I’m more concerned with the semi-colons and .swf filename
that Flash is putting into my relative path on the error message.
Is that normal?

APEX_ITEM.DATE_POPUP and ORA-01830: date format picture ends before conver

Hi,
I am using apex_item.date_popup for a custom tabular form.
When I load the form with the default sysdate it works ok. However when the user submits an invalid date I get: ORA-01830: date format picture ends before converting entire input string.
Ex: apex_item.date_popup (2, NULL, ac.my_date, :f_date_format, LENGTH (:f_date_format), LENGTH (:f_date_format),NULL)
Where f_date_format is 'DD-MON-YYYY'...
If I enter 'abc' in this field and click submit, my validations find that it is an invalid date, so I reload the page with ac.my_date is the value that the user entered (ex: 'abc'). This will cause the error...
I understand why the error occurs, but is it correct that it does happen? Any ways around this?
Thank you.

Hi Scott,
I found the work around. I'll try to make this code more readable later on.
1: Create a HTML region with the following code:
Note: F02 is the "Column" for my date field:
<script type="text/javascript">
function genCalF02(pRowNum,pYyyy,pMm,pSecurityGroupId)
elemArrLen = 0;
if (document.forms[0].f02.length) {
elemArrLen = document.forms[0].f02.length;
elemArrLen = '&F_DATE_FORMAT.'.length;
pMm = '' + pMm;
if (pMm.length == 1)
pMm = '0' + pMm;
w = open("wwv_flow_utilities.show_as_popup_calendar" +
"?p_element_index=" + escape('f02' + '['.substr(0,elemArrLen) + pRowNum + ']'.substr(0,elemArrLen)) +
"&p_form_index=" + escape('0') +
"&p_date_format=" + escape('&F_DATE_FORMAT.') +
"&p_application_format=" + escape('Y') +
"&p_bgcolor=" + escape('#666666') +
"&p_dd=" + escape('') +
"&p_hh=" + escape('') +
"&p_mi=" + escape('') +
"&p_pm=" + escape('') +
"&p_yyyy=" + escape(pYyyy) +
"&p_lang=" + escape('') +
"&p_application_id=" + escape('&APP_ID.') +
"&p_security_group_id=" + escape(pSecurityGroupId) +
"&p_mm=" + escape(pMm),
"winLov",
"Scrollbars=no,resizable=no,width=258,height=210");
// TODO "?p_element_index=" + escape('f02' + '['.substr(0,elemArrLen) + pRowNum.substr(0,elemArrLen) + ']'.substr(0,elemArrLen)) +
if (w.opener == null)
w.opener = self;
w.focus();
</script>
In you're query (or how ever else you are calling apex_item.date_popup)... use something like this instead:
WHEN is_valid_date(my_date) = 'Y' THEN
apex_item.text (2,
my_date,
LENGTH (:f_date_format),
LENGTH (:f_date_format),
NULL,
NULL,
NULL
) || '<a href="javascript:genCalF02(' || (ROWNUM - 1) || ',' || TO_CHAR (TO_DATE (my_date, :f_date_format), 'YYYY') || ','
|| TO_CHAR (TO_DATE (my_date, :f_date_format), 'MM') || ',' || apex_custom_auth.get_security_group_id
|| ')"><img src="/i/asfdcldr.gif" align="middle" alt="Calendar"/></a>'
ELSE
apex_item.text (2,
my_date,
LENGTH (:f_date_format),
LENGTH (:f_date_format),
NULL,
NULL,
NULL
) || '<a href="javascript:genCalF02(' || (ROWNUM - 1) || ',' || TO_CHAR (SYSDATE, 'YYYY') || ','
|| TO_CHAR (SYSDATE, 'MM') || ',' || apex_custom_auth.get_security_group_id
|| ')"><img src="/i/asfdcldr.gif" align="middle" alt="Calendar"/></a>'
END as xxx
This creates the text box with a date popup window beside it.
Again, this is not pretty code which can probably be done in a function etc.
Hope this helps anyone else who has the same issue.

CP5 pre-loader questions re: video

Forgive the long post..
I published a Cap 5 project in which the first 4 slides contain short videos. The pre-loader is set to 70%. When playing the course from a server or LMS the initial load ranges from 1 minute to 5 minutes depending on location and computer. After the initial load reaches 70% the first video shows its own loading screen for a few additional seconds and begins to play. Subsequent videos will also show a brief loader before they play. The video and project sizes are as follows:
- Course SWF is 12.5mb
Slide one video is 827kb
Slide two video is 1.2mb
Slide three video is 1.9mb
Slide four video is 950kb
- All videos are encoded F4V
- Project is published from CP5 on a Mac
- Latest Flash player is being used for all user machines
The Problems:
- On high performance machines with fast internet connections, the content loads and plays as expected, however on slightly older machines, or slow connections the playback is jerky and unpredictable
- Playback performance from a web server is generally better than from the SumTotal LMS regardless of the machine capabilities
- On several occasions the audio for the next slide plays simultaneous with the video from the current slide. Also bullets that are synched with the slide and video will fall out of synch. After reloading or using the nav bar to back up, the slide generally plays as expected.
My questions for the community:
1 - Will the pre-loader load F4V videos before playback? Can someone explain what the pre-loader will load what it will not?
2 - If the preloader does not load video, is there a downside to setting the preloader to a minimum number (say 10%) to at least reduce the initial load cycle?
3 - How do I ensure that audio from the next slide will not play on the current slide or video synchronized with timeline elements do not fall out of synch?
Thanks
Jeff

Hi there,
Please find the answers for your questions.
1 - Will the pre-loader load F4V videos before playback? Can someone explain what the pre-loader will load what it will not?
<ashwin> No, preloader only loads the main Movie. Once the slide with video is encountered the Video load is initiated and this loads the video. FLV video and Animations (if they are externalised) are not loaded while preloading the movie.
</ashwin>
2 - If the preloader does not load video, is there a downside to setting the preloader to a minimum number (say 10%) to at least reduce the initial load cycle?
<ashwin> Yes you can do this but i am not sure if this reduces the project loading time. I will try to explain you the way preloader works. A 10% preloader percentage indicates to load 10% of the SWF size, For instance if the SWF size is 12 MB then the project starts to play once 1.2 MB of the project is loaded. So if the project has rich content in the first few slides then loading may take time as it has it has to load the first slide fully to show the first slide. So it all depends on how the project is created and how the content is distributed in the project.
</ashwin>
3 - How do I ensure that audio from the next slide will not play on the current slide or video synchronized with timeline elements do not fall out of synch?
<ashwin>Do you have the audio from first slide to n slides continuously, if thats the case then in the published output a single audio file will be created with the published SWF and is stored in the SWF (In this case we say audio is sitched). So if a preloader is set to 10%, even though only 10% of the movie will be preloaded the entire audio should be loaded which might create sync issues as the movie will have started to play while the audio is being loaded.
To overcome this you may choose to increase the slide time of the slides containing audio by around 0.1 second. This activity will split the audio in the published output and hence will have small audio fragments to load while the movie is loading.If around 20 slides have audio continuously then you can increase the slide time for around 6-7 slides and not all.
</ashwin>
Try them and let me know if this information helped.
Thanks

QT movie will not pre-load text track for chapters when streaming

We have been trying to stream quicktime files with chapters for some time and have followed every tutorial, message board advice and trick to get this to work but with no luck. I am unable to get the chapters to show up in QTplayer when the video is streaming. I am trying to accomplish exactly what you see on this web page http://media.law.unimelb.edu.au/kalt/
Basically, we have successfully created our movie file (with fast start enabled), successfully created our text track, copied it onto our movie file, and set it to preload, as in the instructions at http://www.apple.com/quicktime/tutorials/chaptertracks.html (I had to roll-back QT Pro as the Preload checkbox has disappeared from 7.4.5!!).
Then we have saved it as a self-contained movie, and it works perfectly, with drop-down chapters in the right places, etc.
As soon as we put the file on our quicktime streaming server however, the file streams great but there are no chapters. If I look at the movie properties of our streaming file, there is no text track listed. The properties of the streaming file on the above web page DOES show the text track listed, so I am guessing that mine is simply not pre-loading the text file, even though I have checked the box to do just that and the chapters work great if I simply open the file locally, just not when it is streaming. I have tried this with many test files, large and small.
Could anyone let me know how I can get that text track to pre-load in the stream and therefore have the chapters appear in the drop-down list in quicktime player when streaming? I would be eternally grateful!

First, you don't have to roll-back QT Pro, as what you want to do can be accomplished with the latest QuickTime.
Second, skip down to the bottom of that page you linked to. You'll find a Step 1 and Step 2 that applies to Streaming QuickTime movies with chapters. This was sort of confusing when I first tried it, but the way you accomplish Step 1 is to start the stream using a computer that has QuickTime Pro, then save the stream as "Self-Contained" (NOT the original movie that resides on your Streaming Server). As when you save any QuickTime stream as Self-Contained, you'll end up with a really tiny movie that simply points to the streaming server.
Once you have that movie, you add the chapters to it (again, not to the movie that resides on your QTSS), then when someone clicks that link (or even if they download that tiny movie to their desktop), the chapter loads immediately (because it's right there) and choosing chapters in it commands the QTSS to begin playing from that point. I've got an example I posted here.

Pre-loading conditional content(pictures etc.) before it needed.
