Progressive download. How to?

Hello!
I need to enable visitors to my web site view video and listen to audio files. I learned from some articles on the internet that there are two ways to achieve it:
1. Real time streaming
2. Progressive download
Are there any examples of progressive download in Java? If I understand it correctly use of JMF is not a very good approach in this case because visitors would need to have JRE and JMF installed on his machine before he can play media files and it is quite large amount to download and install. Is there a better/cost effective solution/approach to realize progressive download than JMF?
Thank you very much.

Yes, JRE is on most PCs nowdays but not in CIS
(former Soviet Union Countries). Aaah.. that was dumb of me. I had been lulled
into a 'false sense of security' by seeing my sister
buy computers for her kids recently, and they all
had Java pre-installed. I was not thinking of "legacy
and older PC's", sorry.
If JMF is used for Progressive Download are
there articles or tutorials, hints online on how
to implement it correctly? And on that matter, I will just add that I only
commented on the parts of your original
message about which I (thought I) knew
something. I had never heard of "progressive
download" before your post!
Perhaps other folks can help you more..

How to Load Progressive-Download Video just when I press Play?

I have set the Progressive-Download video instead of Streaming-Video (because my webserver provider "aruba.it" doesn't offer
streaming videos), in Flash CS4 Professional, and exported to Dreamweaver CS4.
I have also inserted the HTML code in Dreamweaver CS4 to enable FullScreen Playback of Flash .flv Videos.
Now I have a problem:
- When the webpage loads into Internet Explorer 7, it take much time to load all the videos at same time!
Thus I want this:
- I want that the videos start to load just when I press the Play button, individually, not at same time.
- I don't not want that start the load immediately when the webpage opens in IE7.
- I want that the videos start to load content in the same manner of YouTube videos, just when I press play.
How can I do?
What is the HTML code that I should insert into DreamweaverCS4?
I have seen this help page:
http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/fl/video/FLVPlayback.html#lo ad()
At Chapter "Public Methods" I have seen this "load" function:
"Begins loading the FLV file and provides a shortcut for setting the autoPlay property to false and setting the source, totalTime, and isLive properties, if given..."
Can be useful this function?
Horsepower0171.

Excuse me, I am a beginner user of FlashCS4.
OK!
StepByStep:
My site is http://www.cavallodario.it. Please see the third top section called "Sezione 3D">Maya>the last bottom video on the page is published as Streming video (I think)...
There, are all the videos.
I have understood that YouTube video is http streaming.
Instead, in FlashProCS4, I have seen a second Option after ImportVideo Menu (is Flash Media Server streaming?):
1) "Sul Computer" (on the Desktop, local); NOT CHECKED
2) "Già distribuito su un server Web, Flash Video Streaming Service o Flash Media Server"; CHECKED and selected the URL: http://www.cavallodario.it/filmati_Maya/flv/Wagon_01_PAL_Letterbox.flv
> Next > SkinBar with Fullscreen Button (called "SkinUnderPlayStopSeekFullVol.swf") > Next > End.
But I have a doubt if this is a streaming function:
-After published the webpage via FTP with Dreamweaver, in IE7 browser the loading progress bar appears immediately, and loads the video when the webpage appears, not when I press Play Button!
Why this?
How I can do to load the video just when I press the Play button?
- I have seen the "NetConnection / NetStream" classes in the FlashCS4 Help, but I am a confused beginner user and I don't want write an ActionScript code to build a custom navigation bar.
Please response me!
Thanks!

How do I force progressive download?

I have an Adobe Media Server all set up and playing videos over RTMP.
Users on low bandwith settings experience buffering, on occasion. To combat this, I want to force users to download the entire video before they watch any of it.
Through my research, I've found that "Progressive download" is the way to go if I want to do this, though I haven't found how to enable or access this on the server.
How do I force progressive download?

I am in control of the client. I'm using the Strobe Media Playback, and alternatively, a simple flash client using netConnection and netStream.
How do I set it on the client? Is it a change of "rtmp://" to "http://", or do I have to change a flashvar setting or what?
And if I set progressive download on the client, would it be different than using HDS or HLS?
In my http.conf, what I changed is:
Under <Location /hls-vod>
HttpStreamingContentPath
from "../webroot/vod" to "../applications/recorder/streams/_definst_"
All of my videos are in that directory.

How to disable progressive downloads

We have FMS interactive configured to do RTMP and HLS streaming. However the clips still can be downloaded through http://domain.name.com/vod folder. Is there a way to disable progressive downloads? While at it is there a way to disable HDS also? I want to allow HLS and RTMP only.

Reason for your data available for progressive dowload is because its there in webroot. Webroot/<extendend-path> is by default available to any client via http://server-name/<extendend-path> unless you have taken measures to protect it inside Apache's httpd.conf.
You can do one thing. Keep your content outside Apache's webroot. Say C:/myvideos/. for example there is a video there sample.f4v i.e C:/myvideos/sample.f4v
Now you can change the location "HttpStreamingContentPath" pointing to from "../webroot/vod" to "c:/myvideos/" under hls-vod inside httpd.conf (Apache/conf)
<Location /hls-vod>
    HLSHttpStreamingEnabled true
    HLSMediaFileDuration 8000
    HttpStreamingContentPath "C:/myvideos/"
    HLSFmsDirPath ".."
    HLSJITConfAllowed true
   Options -Indexes FollowSymLinks
</Location>
Or you can disable(modify) content availibilty by making appropriate changes unders in httpd.conf
<Directory "../webroot">
    Options -Indexes FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>
To disable HDS-Live, set "HttpStreamingEnabled" to false under hds-live location directive
<Location /hds-live>
    HttpStreamingEnabled false
To disable HDS-vod, set "HttpStreamingJITPEnabled" to false under hds-vod location directive
<Location /hds-vod>
    HttpStreamingJITPEnabled false
To disable HDS-vod offline fragmented content, set "HttpStreamingEnabled" to false under vod location directive
<Location /vod>
    HttpStreamingEnabled false
You need to restart the Apache server after making the changes to get them reflected next time..
Hope it help

What is the difference between SWF and F4V in the context of Streaming or progressive Download?

Hello everybody,
I am absolutely a beginner in working with Captivate and furthermore my technological know how is not that good.
So, I have problems to understand if the export formats SWF and F4V are both capable to be published in the Internet as streaming video and as progressive Download? Well so, I do not really understand the difference between streaming and progessive download either?
Furthermore I was asking myself if this issue depends on how I imported flash videos (there are these two options) in my Captivate project during the production phase?
I would be very thankful for some helping information!
Greetings,
Mareike the beginner

Welcome to our community
I'm not certain I fully understand the differences myself, but will toss out what I believe to be true about the formats. Hopefully, if I'm incorrect in my bellief, someone with more definitive knowledge will chime in.
It was explained to me a couple of years back and is my understanding that "streaming" only applies to a video based format such as F4V, FLV and it doesn't apply to SWF. With SWF, you may specify a preload value. So when the SWF transmits from the web server to the PC, a certain percentage has to be received before play begins. But that's not streaming. It's preloading.
For streaming to occur, the web server establishes a communication channel between the server and the destination PC. This channel is monitored to see what speed is in use. Only enough information is then transmitted to be comfortable at that speed. If the speed improves during the connection, the server serves data at a faster rate. If the connection degrades, the information transmitted is also scaled back so as to accommodate the lower speed.
With SWF, after it has all been downloaded, a savvy user is able to poke around in their temporary internet files and save the SWF for play later. With streaming, this isn't possible because as the stream is viewed, it evaporates from memory.
Seriously hoping others will chime in here to confirm or deny this.
Cheers... Rick

FLV Progressive Download SeekNavCue

Hello! I have been working on this issue for a couple days
now and cannot seem to find the resolution. I have a flash movie
that includes three FLV files that are progressively downloaded. I
have no problems playing them, but when I get to a certain point in
one, I want to switch to the other, but start the second FLV at a
certain cue point. The test works when I play from my hard drive,
but Since the files are progressive download, they don't jump to
the correct cue point when viewed online. Any suggestions on what I
should try next? My code for the FLV switch is below:
This is on the first frame (checks to see if the root var is
set to 1, if not then it should jump to a specific point in the
FLV):
import mx.video.FLVPlayback;
var pam_vid:FLVPlayback;
if (_root.link == 1) {
pam_vid.play();
if (_root.link == 2) {
pam_vid.seekToNavCuePoint(repeatStory);
pam_vid.play();
This script is put on the last frame (detects when the video
file is done playing, then jumps to frame 1 and checks the root
var):
import mx.video.FLVPlayback;
stop();
var listenerObject:Object = new Object();
pam_back.addEventListener("cuePoint",listenerObject);
listenerObject.cuePoint = function(infoObject:Object):Void {
if(infoObject.info.name == "cue2"){
trace("cue2");
_root.link = 2;
gotoAndPlay(1);
thanks,
Christy

It's a snap with Flash 8 Pro. You just attach a skin to the
FLV with all the components (such as volume, mute, play, and pause)
and your good to go. Not sure how it works with earlier versions of
Flash.

Skip to a point in progressive download mp3 before downloaded

Is it possible these days to skip to a point within a progressive download mp3, before this point has preloaded, similar to what i'm seeing with video players such as youtube? in the past, i've used FMS to achieve this, was wondering how people achieved this without using a streaming server.

Actually i think my questions are answered here: http://flowplayer.org/plugins/streaming/pseudostreaming.html
It's talking about movies but i assume the same applies for mp3s. Thanks peoples!

No progressive download for H.264?

I was encoding a 6 minute video for web delivery in H.264 and it appeared that there is no provision for encoding for Fast Start or other setting to allow progressive download. The 6 minute video compressed in H.264 to about 30MB and was only downloadable off our web host as a full download. This required about 20-25 seconds on cable modem. Not a satisfactory result!
Does anyone know how to set for progressive download? I had the same experience when encoding into the variations in QuickTime.
This is crazy. If this is not currently possible, does anyone know if Adobe is taking steps to remedy? Is this remedied in CS4? I have heard reports of excessive crashing in Premiere CS4 so I have been reluctant to upgrade.
Regards.
Jeff

For a meaningful comparison, would you not have to view the same video,
encoded at the same bit rate for each format and in the same frame size and
frame rate?
I am not the expert here, but it seems to me that this condition would
have to be met to farily compare. Easily done of course if you provide your own
video for comparison, and that is exactly what I am trying to do. Can QT
Pro output an H.264 in MPEG-4 as well as QT wrappers?
I am going to experiment with both formats as well as Real Media and
Windows Media at similar settings. I do not have a program to simply encode
swf's without taking a few extra steps. It is cumbersome. To my knowledge,
flv's need to be embedded into a web page or otherwise incorporated into a swf
to be widely viewable. While I have a few players which can play flv's
directly, these are not as widespread as QuickTime or Real Player. Not sure,
but I think that Window's Media Player can play QuickTime files. I do not
try this too much so I am not positive.
Thanks for the help and best wishes. I will probably bite the bullet for
QT Pro in the next day or so. I think it is only around $30.

Progressive download doesn't display

I'm attempting to add video to our site using flv files
created in Premiere Pro and creating the swf files in Flash. The
video is intended to popup in a new window. Everything works
wonderfully inside Flash and in my browser, but when I move it to
the server, it doesn't work. When the button is clicked, the popup
opens and the file name and address displays correctly, however,
the window remains white. When I right-click on the window, I can
see the Flash settings.
I verified with our web administrator that flv is a
registered file type. I read about Enabling the FLV MIME. Is that
the same thing as "registering flv"? Any ideas what else could be
my problem?
Thanks.

I figured out my problem by posted in the DW forums. All of
my paths were correct between the HTML, SWF's, FLV's, and the
JavaScript. So, for those of you experiencing the same thing:
End's up it was the MIME types on my host. The host computer
didn't know how to handle FLV files, just like sometimes on a local
desktop you have to sometimes associate certain file types with
certain programs. It has something to do with the HTML header. All
I had to do was go to my host settings through their website and
add the MIME FLV type.
Responding to the last post:
1. You actually want to save your video out from an AVI
straight to FLV, not mp4 if you are planning on having people view
it through a Flash player. Mp4's have some compression so you don't
want to add another compression on top of that once you change it
to FLV. You can even save an FLV file directly out of Premiere
rather than going the AVI to Sorenson Squeeze route. Better yet,
export an AVI from Premiere and open it Flash Video encoder (free
program). The quality will be determined by your encoding settings
in Premiere/SS/FVE.
2. Progressive download works for every Flash player that
supports FLV's (I forget what the first player was, 6 perhaps). The
only difference between 8 & 9 is that 9 also supports the new
compression codec On2 VP6, which lets you do alpha channels and
compresses a little better. Just use Sorenson codec and you'll
cover your bases.

Mountain Lion is downloading, how can I tell where it is downloading to and how much has downloaded?

Mountain Lion is downloading, how can I tell where it is downloading to and how much has downloaded?

In the "purchases" tab in the App Store you'll see a progress report.
Also once it completes downloading the installer will auto-launch.
Once you get Mountain Lion installed, if you have the Downloads folder in your dock you will get a progress indicator in the dock while it's downloading :-)

Deactivate progressive download in Adobe Flash Player

Concerning progressive download in Adobe Flash Player, I have these questions:
1) Is it possible to deactivate or disable progressive download in Adobe Flash Player? For instance, if I want to watch a 30 minute video on a video site, and I have Adobe Flash Player installed, then by clicking on the video link, Adobe Flash Player will automatically begin to progressively download the file, thus enabling me to watch the video while it is being downloaded. At the end of the download, the entire 30 minute video file is stored in a temporary folder on my computer's hard disc. Supposing I don't want that file to be fully downloaded unto my harddisk, what options do I have to prevent Adobe Flash Player from progressively downloading the said file?
2) Since Adobe Flash Player utilizes progressive downloads, what happens to the downloaded file? Will it be automatically deleted when the browser is closed, or will it remain in the temporary folder?
3) Are there any settings which I can to configure either on the operating system or in the browser which will prevent or deactivate progressive download?
Thanks very much in advance for your reply.
Best regards
Jack

What are local storage settings?
Applications that run in Adobe Flash Player may want to store some information on your computer, but the amount they can store is limited to 100 kilobytes unless you agree to allocate additional space. Local storage settings let you specify how much disk space, if any, applications from a particular website can use to store information on your computer. Note that it is the person or company that has created the application you are using that is requesting such access, not Adobe (unless Adobe has created the application that wants to save the information). In the dialog box shown above, [website] represents the name of the person or company requesting access. It is the responsibility of the person or company requesting access to make it clear to you why they want access and how they plan to use the information they save. You should be aware of the privacy policy of anyone who is requesting access to your computer. For example, see Adobe's privacy policy. Contact the website requesting access for information on their privacy policy.
It's important to understand that even though this settings panel is part of Flash Player, the information will be used by an application created by a third party. Adobe assumes no responsibility for third-party privacy policies, actions of third-party companies in storing information on your computer, or such companies' use of such data or information.
What kind of data can an application that runs in Flash Player store on my computer?
The kind of information stored depends on the application. Information can be anything from your user name to your current score in an interactive game to a list of stocks in your portfolio. The application should make it clear what kind of information it wants to store.
Who has access to the information?
This information may be accessed by an application that is currently running in Flash Player or by another application that runs in Flash Player on the same website. Adobe does not have access to this information (unless Adobe has created the application that wants to save the information).
As discussed in What are local storage settings? above, it is the responsibility of the website requesting access to make it clear to you why they want access and how they plan to use the information. For example, will it be available only to you, or will it be posted in a public place? Who will have access to it in the future? Will it be deleted after a certain period of time? The privacy policy of anyone who is requesting access should address these sorts of issues.
I've already set privacy and disk space options in my browser. How do these settings interact with my Flash Player settings?
You may be aware that some websites work together with your browser to store small amounts of data, called cookies, on your computer for their own use in the future. For example, when you go to a website regularly, it may welcome you by name; your name is probably stored in a cookie, and you can use browser options to determine whether you want cookies or not. You may also have specified in your browser that pages you visit can take up only a certain amount of disk space.
When SWF or FLV content is being played, the settings you select for Flash Player are used in place of options you may have set in your browser. That is, even if you have specified in your browser settings that you do not want cookies placed on your computer, you may be asked if an application that runs in Flash Player can store information. This happens because the information stored by Flash Player is not the same as a cookie; it is used only by the application that runs in Flash Player, and has no relation to any other Internet privacy or security settings you may have set in your browser.
Similarly, the amount of disk space you let the application that runs in Flash Player use has no relation to the amount of disk space you have allotted for stored pages in your browser. That is, when SWF or FLV content is being played, the amount of disk space you allow here is in addition to any space your browser is using for stored pages.
No matter how you may have configured your browser, you still have the option to allow or deny an application that runs in Flash Player permission to store the information, and to specify how much disk space the stored information can occupy, as discussed in the rest of this document.
What are my local storage options?
If you don't want to let applications from this website save any information on your computer, and you don't want to be asked again, select Never. Note that applications from other websites may later ask to store information on your computer. If you don't want applications from any website that you haven't yet visited to store information on your computer, and you don't want to be asked again, use the Global Storage Settings panel.
If you want to let applications from this website save information on your computer, but you want to decide on a case-by-case basis for each application, move the slider to the far left (None). Each time an application from this website wants to save information on your computer, you will see a question asking for more disk space.
If you want to let applications from this website save as much information on your computer as they need to, move the slider to the far right (Unlimited).
If you want to let applications from this website save information on your computer, but want to limit the amount of disk space they can use, move the slider to select 10 KB, 100 KB, 1 MB, or 10 MB. If an application needs more space than you have allotted, you will see a question asking for more disk space while the application is running.
If an application from this website has already saved some information on your computer and you select a value that is lower than the amount of information already stored, Flash Player informs you that any information that has already been saved will be deleted.
If you don't want existing information to be deleted, click Cancel to return to the Local Storage Settings panel, and then select a higher value. Otherwise, click OK to delete the information and return to the application.
How can I change my local storage settings?
You may want to change your local storage settings if, for example, you want to allot more space for information from this website. To display the Local Storage Settings panel:
Right-click (Windows) or Control-click (Macintosh) the application image while it is running.
From the context menu, select Settings, and then click the Local Storage tab.
You can also change storage settings directly with your browser here: http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager03.htm l

HTTP Progressive Download

Hi,
We tried to stream from FMS 3.5 flv files through HTTP,
How can we prevent Progressive download when we stream flv via HTTP?
We tried some configuration but it seems that files are always download to the local computer temp folder
Can someone point to documentation that explain how to stream flv without Progressive download ?
Regards,
Kobi Shalom

If you're already running IIS, there's no reason to use the included Apache installation.
Apache isn't really an integral part of FMS, and IMO, really shouldn't be part of the FMS distribution. When FMS encounters an HTTP requests, it forwards that request to a port defined in fms.ini (8134 by default). If you need to support HTTP redirection from FMS, you could just as well use your existing IIS.
The only benefit I see in using the included apache installation is if you don't already have an httpd server running, and you want to serve both streaming and progressive video. Beyond that, I see no reason to use (or even install) Apache.

Changing existing embedded video to progressive download

First, forgive me - I am not experienced with Flash and am
flapping around with it a bit.
We have some Flash 5 files that included embedded video and
were thus published as QuickTime files. The embedded videos have
been converted to flv files, and I've attempted to follow all the
instructions for progressive download. However, the flvs seem to
either not play or to become embedded in the timeline. All the
examples I've encountered do not also have an existing timeline
with other (non-video) content, and I can't figure out how to do
this.
These files also have embedded audio.
We have three kinds of timelines:
1. Video plays first, followed by audio and graphic content.
2. Video plays somewhere in the middle, with audio and
graphics on both sides.
3. Video plays last.
Most of the videos are less than 30 seconds. I would really
prefer not to recreate these files from scratch. I'd really like to
figure out how to keep the existing file, and play the linked video
at the appropriate time in the timeline.
Any suggestions for samples or tutorials? From my
description, can you tell if I'm missing some simple little fix?
Thanks,
Mary

no way to change the video you already have. Create a new
movie clip and insert your video with progressive dload selected.
Then replace the video frames with the movie clipplaced at the 1st
frame where your movie frames started. The movie will play and the
timeline will continue on.

Merging Progressive Download Files?

I'm looking to combine multiple progressive download files into one. What is the best way to do this?

and is it possible/doable to, for ex, at 20 seconds in to press a key and jump to another video at, for ex, 30 seconds in that clip?
i know how (or used to) to do it with simple clips, just dont know how harder it gets with external videos (with progressive download each time theyre called in).
the idea is to do something like honda's press r video (2 story lines, switch between them when you press "r"), but using about 6 videos, jumping between them at the press of a key.

FLV progressive download and MediaPlayback component???

Hi
I have to use FLV and progressive download. I did that with
the Video Object. That works great. The problem is that Video
Object does not allow us to control movie volume. It does not give
many function to control my movie. So the solution should be to use
the MediaPlayback component that gives me many fonctions, listner,
... But how to make it works with a FLV that reside on the server
but not in Streaming. I need to load it in progressive.
Any idea.

It's a snap with Flash 8 Pro. You just attach a skin to the
FLV with all the components (such as volume, mute, play, and pause)
and your good to go. Not sure how it works with earlier versions of
Flash.
