.FLV Files Corrupt?

Lately, a few videos I have loaded to sites have stopped
playing - this is after a period of playing successfully. I reload
the .FLV file and it plays normally again.
I do not make any changes to the .swf of .flv file -
reloading the .flv file to the server solves the issue. Also, the
size of the .FLV file remains the same.
Anyone know what is going on, or have a similar
experience?

Just to reiterate:
1. A page with a .swf loading a .flv file
2. video plays fine
3. a few months later, video stops part way through
a) consistently stops at the same place
b) download bar shows video fully loaded
4. reloading original .flv file fixes issue

.flv file corruption on server?

i'm trying to use progressive download to play an .flv file
on an html page. i'm using flash and dreamweaver 8, and when i
insert the .flv and open the html file locally with a browser, the
video plays just fine.
however, when i upload the files (along with the flv_player
and skin .swfs) to a server, there is nothing there. any ideas what
might be causing this?
i'm using an intel macbook pro and uploading to a linux
server. i've also tried it on a unix server.
i've run into cases in the past where i've tried to transfer
files from my mac to a server or email a file to someone else, and
the file won't work, i guess it gets corrupted in the transfer. in
those cases, i just enclosed the files into a .zip folder and
transferred that, and then when the user on the other end unzips
it, the files are fine.
however, this doesn't seem like a practical solution for this
particular problem, assuming that's even the case.
any ideas, or anyone else encounter this out there? i saw
another post with a similar problem, but no one seems to have
replied to it yet. does that mean nobody knows how to address
this?

URL?
It is one of two things...
#1 - Mime type for FLV on server is not set:
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_19439
#2 - Path to FLV is incorrectly pointing at your local
machine instead of using a relative path.

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

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!

Starting and Stopping FMLE from command line yields corrupt .flv files

I am using FMLE to record and live stream TV content. In order to this I am remotely calling FMLEcmd in order to start and stop encoding processes. The problem that I am running in to is that the .flv files generated are corrupt. The odd thing is that if I use the exact same profile XML from the GUI, then the encoding process works just fine and results appear as intended.
Here is the way my workflow works:
I start the process by calling
FMLEcmd /p C:\lighttpd\htdocs\xml\default.xml /l C:\lighttpd\htdocs\logs\log.txt
then at the conclusion of the recording I call
FMLEcmd /s "C:\lighttpd\htdocs\files\default.flv"
When I attempt to open the files using FFmpeg I get a codec error saying that no codecs were detected. When I attempt to open the files in VLC I get a error saying that the media types are "Undf". When I attempt to open or modify the files with flvtool2 I get an end-of-file error. My guess is that my stop command is incorrect and somehow abruptly stopping the stream, but I don't know another way to stop the stream. Do I need to specify a specific stream duration in the XML and make sure to call the stop command *after* the duration has been reached? What would cause this codec corruption when the same profile works properly from the GUI?
Here is the profile I am attempting to use.

Anyone have a clue how I can open or convert the Adobe Connect FLV file?

I'm searching for an answer to almost the same exact problem, using almost the same exact hardware and software. Has an answer been found?
The files that I'm trying to burn come from eMusic, and they are formatted mp3. Recently, (after the iTunes update to 9.2.3?,) they would not drag and drop from iTunes into Toast. From several different discussions I've tried working around this by dragging to the desktop first then dragging and dropping to Toast, going to Toast from a programmer's homemade help window, " iToons," and today, after talking with Apple support, going directly to Toast from my eMusic folder. Alas, all recordings do not perform like they use to. Sometimes they play and sometimes not. There is one I managed, that is listenable, but sometimes I have to put it in my car stereo over and over again as it gets ejected with an error code, sometimes, finally it takes it... Some of the recordings on other disks I've burned are not clean - they have white-noise sounds creeping in... I use to have none of these problems. One time as I was listening to a CD that managed to play, and it just stopped playing... Is there an answer out there to get back to how it use to be? Thanks for you help.

Quicktime and flv files

I have just bought quicktime pro because research suggested it would open a flv file and convert it. Having gone through a painful process of having to redownload and reinstall various add ons it is still not working only opening the first few seconds of the file. Can anyone suggest a solution?

Quicktime X is a great little piece of software. However, Quicktime X is very finicky on which codec/file format it can decode/play.
Luckily, there are DOZENS of alternative video/media players and extensions available for the Mac. Some of them are even FREE. Some of the better FREE ones include...
PERIAN (quicktime extension)
http://www.macupdate.com/app/mac/22923/perian
QUICKTIME 7.6.6
http://support.apple.com/kb/DL923
VLC Media Player
http://www.macupdate.com/app/mac/5758/vlc-media-player
NICEPLAYER
http://www.macupdate.com/app/mac/15136/niceplayer
... And if none of those work, there is a possibility that, that video file may be corrupted.

Please help me with .flv files

Hi Everyone, first of I am a newbie when it comes to
dreamweaver and flash. I am trying to create a slideshow video to
play on my website. I am haveing ZERO luck this is day 3 of this
adventure and I just can't figure it out.
This is what I want to have my slideshow look like.
http://www.mod4.com/slideshows/erin/
However I don't know if I'm using the right programs or
exporting things correctly cause my slideshows are grainy distorted
and look like dung.
I have After Effects, Premier Pro, AVID Express HD, Flash 8,
Dreamweaver and Frontpage at my disposal. For the slideshow I am
using Iphoto as that program does the Ken burns effect very easeily
and quickly. It then exports them as a quicktime.
But my problem is getting the .flv file to be clean, small
and playing on my website without any problems.
I've gotten it to play but only for like 10 seconds out of
the 3 minutes.

ANY help would be apprecitated.
Thanks!

Well, the Flash video file you've uploaded (

) is only
11.5 seconds in duration:
Perhaps it's become corrupted during upload? Does is play OK
locally for
you?

Flash 8 Video Encoder- Necessary Codec or File Corrupt

I have a bunch of quicktime files I'm looking to convert but
keeping getting this error from the Flash 8 encoder when I try to
encode or click 'settings':
You won't be able to encode this file. Your computer doesn't
have the necessary codec or the file is corrupt.
I am having success with other quicktime vids, so what gives?
Thanks

That kind of question is very hard to answer. There is so
many factors to consider,
it will be one, never ending guessing game.
Try multiple videos, divx, mov , wmv etc... See if you can
mange to get any of these
to work. If none than perhaps the FLV player is not set up
properly or the encoding
setting isn't correct. If some of these work, than perhaps is
the video in question
that is Flash incompatible and you might need to save it in
another format using video
editing tools. Also make sure that the browser players are
compatible with the file version
you publishing to.
Than, after having all these answers, we can't start to try
to figure
out what and where it goes wrong.

Premiere Pro is no longer reconnecting certain FLV files

I have a clip that premiere is reporting as "disconnected media". It is right where it started, and the directory has not changed.
When I try to reconnect the media (which is the exact same file name still), the file is greyed out in finder, so I am unable to reconnect it. I'm also unable to import the clip new.
Why is premiere preventing me from dealing with this FLV file? It plays perfectly find on VLC, and it is not a corrupt file.

Internal or external drive, and if so, what connection?

Problems importing some flv files

I'm using Premiere CS4. I am able to import some flash .flv video files without difficulty, but in many cases a file will not import successfully. Instead, I get the following error message:
The file appears to have no media data.
Which is odd, since such files play without any problem in, say, Real Player.
I'll be grateful for any help with this.

You might also want to give Moyea's FLV Importer a try. Their site was down when I tried, but I was just on it a few days ago. Give them time to get their server back up. Now, if the FLV is corrupt (though it seems to play fine), there might be issues. Also, there is a great deal of difference between playing an AV file, and editing that same file.
For conversions, I've had success with FLV to AVI.
Good luck,
Hunt

FLV File does not play when published to my web server

Hi. I have created a short video in VC3 and selected the FLV option to create a web page. When I uploaded the entire file content to my web server (windows 2003 server hosted at Network Solutions) the FLV file will not play. Now... if I do the same with a WMV tile, the video plays.
You can view the file at
http://www.airforcehomeseller.com/videos/va_education/VATutorials/index.htm
We have another video published in WMV format, although the video vs audio sync is out of wack at the moment, at
http://www.airforcehomeseller.com/videos/Energy%20Pricing%20101/index.htm
What am I doing wrong?
Any help would be greatly appreciated.

Hi again
You should probably double-check to ensure the standard.js file was also copied in when the HTML page was imported. It should be there but it never hurts to double check.
You might also perform a double-check to ensure things ended up in the correct folder (if you are organizing your project into folders). It could be that you moved the HTML page into a different folder and orphaned the JavaScript file.
Cheers... Rick

Is there a cure for persistent file corruptions across the suite?

i am having terrible and consistent problems with file corruptions across the suite. for example…
1: i collected for output (indesign) – corrupted over 100 small images that were linked.
2: opened an indesign job and all linked files failed to update and could not be imported (simply would not import those files and were all corrupted).
3: had a hang in photoshop followed by a 150:30 error (would not open any of my applications). this prompted a clean install of system and adobe cs4 see below
4: most recently, had a hang in photoshop (photoshop will also no "force quit") whilst indesign was open. two of my image files corrupted and, most surprisingly, all my illustrator files that i had placed also corrupted (will not even open in illustrator any more). illustrator was not even running at the time, so, get this – a hang in photoshop destroys illustrator files simply because they are placed in indesign.
this last event has made me more certain than ever that there is a fundamental problem at the cs4 core.
can anyone help?
please note the following:
i am running a macintosh imac, 2.66 GHz Intel Core 2 Duo (latest imac), with 4 GB 1067 MHz DDR3 ram.
before this last disaster, i had reloaded the system software (archive and install), and updated it all the way to version 10.5.8
i then uninstalled the creative suite, ran the cleanscript from adobe, reloaded the creative suite, downloaded all the cs4 updates
(so, latest mac, latest system, latest cs4 – all clean installs).
is there something i can do? or is this just a very unstable and disappointing upgrade – i have had nothing but problems from day one!
many thanks if anyone has any advice.

Re: 150:30 error:
Please try this KB article's solutions, and report back on how it went for you. If you can provide details about any recent OS updates, backups, or migrations, that would help is nail down the root cause of the new rash of this error for Mac users recently:

How can I mask on flv file in flash cs4?

Hi,
I am new to Flash CS4. I saw one video on how to use flv file in flash and mask it. It is working fine when I am using the following option while importing a video file to flash:
Load external video with playback component
But when I tried with the following option it doesn't show the background, it shows only movie which is playing nicely. But not the background which has a bill board.
Embed FLV in SWF and play in timeline
It seems the mask is not working with this option.
How to solve this problem? Please help.
Actually it should be like the above.
But when I am using the option Embed FLV in SWF and play in timeline while importing the flv video, getting the result like below: It is not showing the Bill board as above.
See the layers created:

Hi,

Flash CS5 unable to play .FLV files on Macbook Pro

I have a colleague who is trying to put together a Flash package for me on her macbook pro. It needs to play an flv file. She is unable to play flv files on her computer either in Flash or using the Adobe Media Player. I have no problem playing the same files on my macbook pro, we're both running the latest OS and have version 1.8 of Adobe Media Player.
She went to the Adobe site to download the latest version of Adobe Media Player, hoping that might include whatever component is missing on her system. Because of Adobe's decision not to distribute AMP that didn't help. She has Flash Professional CS5 11.0.2 on her system. When she imports an flv video into a Flash project and tries to play it she gets an error message saying it can't stream the video. Note that the video is on her hard drive, it is NOT on the internet so no streaming should be required.
The actual error message is: "the video player is in the connection error state. It enters this state when a video stream attempted to load but was unsuccessful. There are two possible reasons for the error: no connection to the server or the stream was not found."
Since it's a file on her hard drive, and she has loaded the file into the Adobe development environment successfully, the one thing we know for certain is that neither of these reasons is correct. Something is obviously missing on her system, what is it and what can we do to fix it?

I'm getting error too (Error #2044: Unhandled NetStatusEvent:. level=error, code=NetStream.Play.StreamNotFound). I'm getting this with CS5. This file was previously made in CS4 and never got this error.
Everything (fla and flv too) is on external hard disk.
As this work requires to be exported to mov, I've found out that everything needs to be on the mac (don't know for pc), like on desktop.
So, let me wrap up disadvantages I got with Flash CS5:
- TextField.embedFont makes the font disappear in CS5, so I can't use it, so I can't "play" with text in a comfortable way (in CS4, with embedFont = true, I was able to rotate and stuff). Now I have to make a bitmap out of it. It means 3 lines of code and a new variable, instead of just an easy one.
- I have to rebuild my entire source path structure for AS classes, as my old one (that took me years of effort to be reasonable and used to work just fine in CS4).
- I have to move stuff from my hard drive to the desktop, to make flv be played and to make a mov out of my animation.
CS5 is making my job harder and making me lose a lot of time to find out errors that have no good reason to exist (it was not error. just "place CS5 doesn't like").
