More flv file issues

hello out there !
What is the reason that at some sites when I go to dl flv files through the activity window of the windows safari menu by double clicking on the flv file I get a text rather then a get video fora dl. And more importantly how do I get around that ? A site like teacher tube has files I'd like to save into Qt. If I could dl the actual flv I could do the rest.
thanks

You'll need to manually remove the .txt file extension after the download is complete.
Many Sites use PHP scripts to serve files from a data base. Some need updating (TeacherTube is one) so they don't append file extensions for downloads. The file works in the page code and they don't expect users to be "borrowing" the file via direct download.

Uploading flv files issue

I upgraded to DW CS3 and now when I try to upload a flv file,
it says it can't complete it and the file isn't updated. I go back
to my old version of DR8 and it works just fine. When I synchronize
in CS3 it will tel me that files need to be updated, but when I try
to do it, it says it can't complete. Why? This doesn't happen EVERY
time though which makes it even harder to figure out. I tried
deleting the version on the server, but it still won't upload the
new version. How am I supposed to update my site and get the new
files up? I make a lot of changes to the site, then synchronize
it.That is the only way to be sure I haven't missed some files. Can
someone tell me why it works ok in DW8 but not in CS3? Is there a
setting somwhere I need to change? Thanks for any help.

Welcome to our community, Leslie
I'm thinking that what's happening here is the LMS simply
doesn't recognize that the .FLVs should be included. So I'm
wondering if the following workaround would work for you. When you
insert the FLV reference, code an absolute path. For example, lets
say the LMS serves the Captivate up and the logical path is
http://www.somesite.com/training/CaptivateMovie.htm.
Maybe you store all the .FLV files in this locaton:
http://www.somesite.com/training/videos.
So you would then code the link to your FLV to use that explicit
path of
http://www.somesite.com/training/videos/MyVideo.FLV.
I'm not 100% sure this will work, but I can't really fathom a
reason it shouldn't.
Cheers... Rick

What's it take to show FLV files?

I'm fairly far out of the Flash loop.
We'd like to start hosting FLV files on our site. These are
being produced
by external vendors.
Once I get the FLV file, what would I need to do to add it to
our site. I
assume I'd need some sort of flash based FLV player.
Would I need to manually set up each FLV file in a SWF
manually in Flash? Or
is there a standalond Flash component (SWF) that could be
configured on the
server movie-by-movie to eliminate the need for setting each
one up in
Flash.
The issue is that we're going to be getting more and more FLV
files with
more and more employees wanting them posted on their
individual pages and we
don't want to be burdened with having to create a custom SWF
for each and
every video if at all possible.
-Darrel

Darrel,
I'm sure there are components out there but I've always
created my own or
created them for my clients. I've done this a couple ways:
dump all the flv
files in a folder on the server and do a dir read with a
server side script
and out put in an xml format that flash can read. Or, have a
db with the
info to the path to the flvs, then do the same xml format for
flash to use.
As for the flash file itself, you could do this any number of
ways once you
have the flv files' information.

Adobe Media Encoder Quality Issues for 4:3 FLV Files

I am working in a 480x360 window for a FLV file. Whether I export a 60 minute presentation or a 10 second pre-roll FLV file, the rendered file quality is distorted and poor. I have done the same work in CS3, but as I changed computers, the CS4 was installed.
With the video presentation, orginally capturing the video is set as .9 Pixel Aspect Ration, but interpreting the footage to 1.0 is also an issue.
The quality of video that is being produced is much worse then CS3 and unuseable in most cases.
Frame Dimensions: 480x360
Frame Rate: Same as source. (29.97)
Endoding: CBR
Passes: 2
Bitrate: 500
Audio: Mono / 48

A couple things:
1) VP6 and H.264 are codecs that operate in "mod16". What that means is that they begin by dividing a video image into 16x16 blocks, followed by 8x8, 8x4, and 4x4 blocks. This makes for a more efficient encode. Your 240 dimension is fine (240 / 16 = 15), but the 515 dimension could be slightly problematic (515 / 16 = 32.1875). The codec will stretch or compress the image to fit into that dimension, and so can result in a lower quality encode. If you can, try encoding at 512x240, by cropping a couple pixels in the horizontal dimension. May not make a big difference, but it's good practice with these codecs.
2) To me, your original encode looks like the product of Adobe's less-that-capable deinterlacing scheme. You're dealing with progressive assets and a progressive target. I'd submit that the reason your 1280x720 encode looks better is that you're using a progressive preset, with no deinterlacing necessary when exporting. One thing you could check is the field order of your original sequence setup--if it's interlaced, I'd say you have your answer. If it's progressive--well, then I'm wrong :) However, you didn't explicitly say this in your original post, but it's worth a look.
If it is interlaced, I don't think you can change that after the sequence is started, so just create a new sequence with the proper progressive settings, and copy and paste the original sequence contents into that one. Now, when you export, there will be no need for deinterlacing.
Anyway, that's my guess...

On my mac I have both Quicktime X and Quicktime 7 pro. Both applications seem to be crashing quite often lately. This happens when playing all files types. I notice it more with .flv file. It usually happens when i grab the time slider bar and try to move

On my mac I have both Quicktime X and Quicktime 7 pro. Both applications seem to be crashing quite often lately. This happens when playing all files types. I notice it more with .flv file. It usually happens when i grab the time slider bar and try to move it. The apps will freeze and I have to "force quit" to get them to close. Sometimes putting the computer to sleep and waking it up helps. Is there a way to remedy this?

Issue with FLV file in Photoshop Extended

Hi,
I have Adobe Photoshop Extended & Adobe Flash Professional and Quicktime 7 installed. The photoshop documentation states that it supports importation of FLV files. Yet when I select File -> Import -> Video Frames to Layers the only options are MOV, AVI, MPG, MPEG no FLV. Is there something else I need to do or have to import FLV's into PS Ext.?

Thanks for the reply. Unfortunately -NO- thats what I was given and I was hoping to avoid transcoding it to MOV so I could open the file in frame animation mode and make the changes. So I guess I'm stuck downstream

Green Screen issue with an flv file

I am attempting to create a Green Screen were I walk out onto my website and speak to the viewer. Everything looks good and plays within Premiere but after exporting and placing it on my webpage a black background shows instead of the background being transparent. can someone help with what I am doing wrong?

> and are flv files the only ones that I would run into this with?
There are other kinds of files that can include alpha channels (transparency). Just so that you know what to look for, QuickTime and some other formats require you to specify the inclusion of an alpha channel from a color depth or channels menu. In some cases, a plus sign (as in Millions Of Colors+) denotes an alpha channel. Similarly, choosing to output to 32 bits per pixel implies an output depth of 8 bits per channel for each of four channels: RGBA (where A is for alpha).
But, yes, FLV with video encoded with the On2 VP6 codec is the main format for web video that supports alpha channels.

Unable to opn FLV files and more with newest Quicktime vs 7 Pro

Hi and thanks in advance -
Suddenly I cannot open FLV files and I have the Flip4Mac etc plugins. NO LUCK. This is a waste of money patience and time ... or does anyone know of a way to create harmony in the cacophanous quicktime wannabe world. I have a new macbook which I adore and I am ready to throw it down the loo.
PLEASE help. It's much appreciated.

FLV is Flash Video. QuickTime isn't used (normally)
to view them and most of use use the free Flash
Player and its browser plug-in.
The free Perian http://perian.org/ component may help
you.
hi and many thanks for the advise - stupid of me not to see that the flv = flash. I have had the perian plugin installed and running 100 percent for some time.
I'll give it another go nonetheless and again thanks for the input! BTW the flash player has been running fine too. Perhaps a conflict?

Stuttering flv playback issue- need help asap

We need help asap. Have a project is due to deliver today (5/14).
We have a video to go on a dvd-rom, live action with Motion Graphics behind.
When output is done thru Projector the Motion Graphics stutter as they scroll.
Here is more technical info:
Stuttering flv playback issue:
Prores 422 timeline 29.97fps 1280x720 output from fcp using current settings.
Mov file is approx 7gb, plays relatively smooth on a mac pro with no raid.
Frame by frame analysis shows all frames are present with no jumps tears or skips.
Tried several output paths, programs and settings to create a smooth flv file to no avail.
We adjusted data rates from 2k, 3.5k, 4k and 8k, no luck
We adjusted keyframe rates from low to all frames, no luck.
We tried cs3 flash encoder, cs5 media encoder, squeeze ect, same results.
Playback in the flash projector seems to choke slightly no matter what we do.
Have also posted in the Director Forum.
Any help much appreciated!

Here are a few ideas off the top of my head:
Try playing the file using a different xtra, sometimes different ones will work better. If you have Director 11.5, there is a native flv playback xtra.
You can build a player easily in Flash using the flvPlayback component, then bring that into Director as a swf.
Once you have the video in Director, try making the member Direct To Stage (DTS). If it is already DTS, try making it not DTS.
Make sure the video is not transparent, and nothing in Director overlaps the video... in fact, when the video is playing, nothing should be moving at all, and try to keep the amount of code that is running to a minimum.
Try lowering your video's data rate further or try using a different codec.
Using VBR (Variable Bit Rate) compression often makes the video appear to play smoother.
Try compressing the flv with different software. FFMpeg, for example, is free and does a very good job, often better than the Flash Video Encoder that comes with Flash/Creative Suite.

HOW TO TURN A .FLV FILE INTO AN SWF IN ADOBE?

Questions,,,,,
1. In a flash slide,,,,,How do I add effects to the movie,
like an intro black curtain coming up from the top and closing down
on the bottom,,,,,,to make it look more
professional?,,,,,,,,,,,like this video-SUMMER NIGHTS-
http://music.yahoo.com/ar-289037-videos--Lil-Rob
2. How do I convert .flv files to swf files so I can upload
them to my site,,,,,because thats all it excepts?

Peace,
I will try to answer both questions. You abviously know how
to creat an .FLV file. when you load you files on the server you
must place the .SWF and the .FLV in the same folder. With that you
will create your link to the .SWF file.
In regards to the other issue. I am incline to think that
what you see is a video effect and not a Flash one. If I where to
try this I would upload my video into the time line and add a new
layor to hold my effect. This should do it. But it will of course
make you .SWF larger than if you did the effect in a video editing
program.
I hope I helped some how.
Peace

Difficulty using hardcoded swf file to display flv files

Hi,
I have created a swf player using the flvplayback component to display flv files. The document in flash is 275 pixels wide by 130px pixels long. I also have my video component (flyPlayBack) set at 275px by 100px to display the playback controls. My flash code is my simple like the following
import fl.video.*;
var myflashvars:Object = new Object();
myflashvars = this.loaderInfo.parameters;
var fullVideoPath:String = "";
for (var item:String in myflashvars)
if(item == "filename")
fullVideoPath = myflashvars[item];
videoPlayer.source = fullVideoPath;
So using the above it should play the video and does.
(1) First question is I tried playing 2 different videos in my html code.
<object classid='clsid:d27cdb6e-ae6d-11cf-96b8-444553540000' codebase='http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=10,0,0,0' width='275' height='130'>
<param name='allowFullScreen' value='true' />
<param name='movie' value='moviePlayer.swf' />
<param name='wmode' value='window' />
<param name='scale' value='showall' />
<param name='flashvars' value='filename=sample_sorenson2.flv' />
<embed width='275' height='130' allowFullScreen='true' type='application/x-shockwave-flash' src='moviePlayer.swf' pluginspage='http://www.macromedia.com/go/getflashplayer' wmode='window' scale='showall' flashvars='filename=sample_sorenson2.flv' />
</object>
Just like above works fine. But I tried playing 2 different videos, the first video image is below
The second video image is below
I notice the video sizes are different but not the video player size, is this to do a thing called aspect ratio? Is it possible to change this using my simple actionscript code above?
(2) I also tried the full screen button but the video only takes up part of the screen, as shown below. sorry about image size.
Is this a common occurance, is there a way to access the buttons on the flyplayback instance using actionscript and overridding the behaviour? Any advice upon my current situation would be much appreciated. Thanks.

To me the first two screen shots look like you set the wrong aspect ratio/screen size. I don't see any scaling of the player at all... only black bars on sides because the video didn't fill the entire video player display.
And yes, there is a much more powerful and versatile means of displaying Flash video, called NetStream. You can design your own player and have better control over the display. I always use NetStream rather than the FLVPlayback.
But if you are having sizing issues introduced during the creation of the video... then the player itself is not necessarily going to fix that. You need to know the correct display size and aspect ratio for each video you plan to display.
However, you can somewhat adjust the display size for each video using some actionscript... as you see here:
http://www.cataractvideo.com/cv/physicians/cataract_surgery.html
an example of a larger (high brandwidth) version and a smaller (lower bandwidth) version... depending on which button you click.
More on NetStream:

Recorded FLV files contain corrupt timestamps

Howdy -
I'm running FMS 4.5.3 r2005 on standard AWS Linux box. I'm recording the streams using NetStream.publish("appendWithGap") from a small custom Flash app running on IE+Windows.
Usually, the generated .flv file is fine. However, I've found a number of cases where the .flv file generated was corrupt. By using ffprobe -show_packets I'm able to see that the presentation timestamp (PTS) of sequential packets occasionally remain the same. This happens for both audio and video at times. For example, consider the output of the command:
$ ffprobe -show_packets saved.flv | egrep -e '(pts=|codec)'
codec_type=video
pts=0
codec_type=video
pts=0
codec_type=video
pts=0
codec_type=video
pts=0
codec_type=video
pts=0
codec_type=video
pts=0
codec_type=video
pts=3912
codec_type=video
pts=3944
codec_type=video
pts=3944
codec_type=video
pts=3944
codec_type=video
pts=3944
codec_type=video
pts=3944
codec_type=video
pts=3944
codec_type=video
pts=3944
codec_type=video
pts=3944
I really don't know much about the internals of the FLV format, but I assume that invalid timestamps like these make for a non-playable (corrupt) video.
Any idea what may cause FMS to record such a video?
What kind of information would be helpful to debug this?
Obviously, my client expects every video recorded to be one that an be played back, and so these corrupt videos are alarming to say the least.
FYI, due to privacy restrictions I can't share the recorded video without a signed NDA. If it would help, I can provide the entire output of ffprobe.
Thanks,
Ben

Flvcheck has validated the format of file, and it is correct. The logs "Adding Silence message" indicates that audio message was expected and is not recieved after a particular time check, because of which video may appear stalled.
Flvcheck may claim the file is valid, but event after running flvcheck -s the video is corrupt. According to ffprobe, many of the timestamps are still the same. When I attempt to play the file in an flv player, the entire video is run through up front in sort of a fast-forward view, and then the audio plays out more or less normally.
This makes sense, as the video player is probably playing all these frames with the same timestamp sequentially, which makes for the fast-forward effect.
To debug this issue, a good starting point would be, validating the input to FMS. FMS records what is published to it.
Does FMS tinker with the video frame timestamps, or are they just passed through to the file system?
Since you are able to reproduce this issue, can you please enable livestream logging and check if input stream to FMS is different from what it is recording.
Unfortunately I can't regularly reproduce it - though it does happen on a somewhat regular basis (it was happening a couple times a week).
Is it safe to turn live stream logging on for a few days to see if I can catch this issue happening? Or, will live logging chew up resources and cause issues?
Thanks for the assistance!

Inserting flv file in Dreamweaver CS4

When I insert a flv file using Dreamweavr CS4 using asp (Windows XP, SP3 and IE8), I only get two additional files generated (FLV-PlayerProgressive.swf and a skins file. I get no other files generated, either in my root folder of a Scripts folder. FLV file works fine in Live Mode, but all I get is a white box when I upload the files to my server. I've read numerous similar questions. Has anyone ever got a good answer? How can I resolve this issue? I appreciate any help from anyone.

I have checked numerous reference materials concerning this problem, and cannot really find any answer as to why DW CS4 is not inserting the files (for some users). I have even tried using different programs to encode an flv file, and creating an html page direct from within flash CS4, just to see if different files are created (definitely more options etc), but to no avail.
The files DW should create are -
FLVPlayer_Progressive.swf,
Halo_Skin_3.swf (this is a skins file and can be any one of 9 available)
2 files in a Scripts folder named –
swfobject_modified.js
expressInstall.swf
In the head content it should insert the following -
<script src="Scripts/swfobject_modified.js" type="text/javascript"></script>
The only option I can recommend, is to insert the flv into a new (otherwise blank) html file, and then copy the code from there (providing it works of course).
I know this is a problem for many people, and I have even considered asking the forum administrators if I could write an FAQ on how-to and possible solutions.
If DW is not inserting the files mentioned above it may be worth while trying an uninstall / reinstall, but my recommendation is to first create a fictitious site, and then insert an flv into a blank html file (as mentioned above), just to test if that works.

Playing various flv files in FLVPlayer from HTML

I have a .swf file (id=myVideo) that contains an FLVPlayer
instance (myFLVPlayer) embedded (object and embed) on my web page.
In a separate <DIV> I feature several thumbnails and
descriptions of videos that the visitor can play by clicking the
image.
Can I use javascript to call
myVideo.myFLVPlayer.contentPath="myselection.flv" as an onClick
action in the HTML?
I'm using Flash 8 and AS2.
Any suggestions, examples, or links would be
appreciated.

Thanks for the input.
The approach of opening another window doesn't fit in with
the look and feel (design values and aesthetics) of the site. I
suppose I could make a separate .html for each video, keeping the
remainder of the page identical. But this would create a
maintenance nightmare as well as creating more interaction with the
server.
I also realize that I could just put the thumbnails and AS
directly into the .swf and make it work technically. But then as I
add new videos in the future I'd have to make changes to the .fla
and re-publish the .swf. At some point in time, the Stage would
have to be so large as to render that approach impractical. In
addition, it would reduce my flexibility to place thumbnail objects
in the browser window with respect to other HTML/CSS.
So, bottom line is that what I'm looking for is the right way
to go HTML->Javascript->Flash. I know that Javascript can
talk to the Flash instance. The question is, what is the best
approach to allow it to touch the FLVPlayer instance within my
.swf?
Admittedly, it's become more of an issue with me because I'm
using Flash 8 and AS2. Much of the documentation I've found applies
to later versions of both. Because of design changes as the
products evolved, most of that isn't useable for me. It does get
confusing.
Any help, examples, or links would be appreciated.
