Live vs. archive of .flv files

I am playing some short videos (.flv files ) in a presentation. Within the live presentation, the audio plays, but the screen is black. However, on playback of the archive, everything looks great, both video and audio. Any idea why this might be happening?
Should add that these files are being played from the content library.

Live Stream Pre-Recorded FLV File

Hi I'm using FME 2.5 to stream a web cam feed (to Akamai).
Has anyone ever used this set-up (or something similar) to deliver
a pre-recorded video file? Basically, I'd like to use a file as the
video input device.

Normally, only a device which appears as a video camera
driver will be supported for live streaming. That includes USB web
cams and firewire cameras.
However when using programs like MSN or Yahoo chat, many
users have successfully used "virtual camera driver" software,
which supplies images from a file source, but appears to the system
to be a physical (camera) device.
So for example, without making a specific recommendation,
"Broadcaster StudioPRO" appears to be one such virtual camera
driver :

Probably the best approach is to hunt on (insert favourite
search engine) for the search term above, in conjunction with "MSN
messenger" or "Yahoo messenger" to restrict the search
results.

How to write live video to .flv file

We have an application that sends a live stream to offices in
different locations. We'd like to capture that stream at the
receiving end and write it to an .flv file so those who couldn't
make the live broadcast can see the video on demand.
Can anyone point me to a link that describes how to capture a
live audio/video stream with AIR and write it to a local file store
on the receiving end? We want to store the files remotely rather
than using a central file store. I've seen how to write text files
but not .flv's.
Thanks for any direction you can provide.

There are two solutions here that I see, but one is probably more reasonable than the other. Without the use of a streaming media server, you can't really record video/audio. However, the FLV spec is open source and you can accomplish a "recording" by writing bitmap data bytes to a flv file (using the open source spec). This won't capture the audio though, and you can't do that without a streaming server. Also, if you're recording long videos, chances are the writing will either make your application unresponsive/crash it, or the saving time if you broke it down to manageble chuncks would take forever.
The second option, probably what you want, is a streaming server. Whether it be Red5, Wowza, FMS, etc, you'll be able to accomplish what you want, and it should be fairly easy. All be it much more expensive. For what you're describing though, recording live streams, it is probably the most likely approach.

FLV file not opening up in media encoder

I am on a unique job where we are trying to figure out our workflow for video live and on-demand production. Basically, we will be streaming live video during the day and then we would then like to post the video that just went live and have it available in our on-demand archives. For our on-demand, we have to have 3 different flv files at 3 different bitrates since we have no idea what our audience's individual computer/internet can handle.
Because we are doing a high volume of video for this job over the course of two weeks, I am trying to streamline our workflow so that my editors don't have to deal with long hours of babysitting a computer while it is encoding. Because we have to go from injesting DV footage, then exporting QT, and compressor to make it a H.264 file since Media Encoder cannot read FCP QT files, and then into media encoder to make it to flv. That is a lot of steps to be taking. We also have lots of other things to edit aside from the live material.
We ourselves are sending out the video live on line, so permission is not an issue and we are not ripping off things off of big network websites at all. You see, the video is encoding as it is going out and I found a way to record the flv video and maintain it in flv format. However, we would just like to trim the heads and tails for the on-demand version as well create two other flv versions with a different bit rate.
For some reason, when I open the flv file that we recorded, media encoder does not see anything. I took that same test flv file and put it in three different media players/compression software. The flv opens in media streamclip, Adobe Media Player, and Sorensen Squeeze, so I don't understand why you don't see anything when it is in Media Encoder.
I was even able to trim and re-compress the recorded flv to a lower bitrate flv file. I don't really want to use Sorensen because I tested versus Media Encoder and it is really slow compared to Media Encoder. Can someone help me?
Thanks in advanced.

I don't think that Adobe's Media Encoder can open FLV files at all, it only creates them.
Alternatively you can use some of the tools below to top & tail your videofiles:
- After Effects CS4
- Premiere CS4
- RichFLV (www.richapps.de)
Regarding workflow, have you looked into Adobe's Flash Media Encoding Server?

Editing FLV files - Split / Merge

Our studio is moving to a Flash video streaming solution from
a RealVideo streaming one. We stream multiple live streams daily
and archive our streams as well and there are times when we'd like
to edit the .flv video files to cut out a section or maybe merge
two flv files. For RealVideo files, this can be done using the Real
Media editor that is built into Real Producer. Is there any
solution to accomplish this with FLV files?
I've scoured google and I've found workarounds that involved
converting the .flv file into an avi or an mpeg, editing it and
then converting it back using multiple programs and plugins to
accomplish this, but that process is too complicated for most of
the end-users in our studio and converting the format over and over
obviously causes degradation in the quality of the video. Has Adobe
created a standalone tool to split/merge flv files? If anybody has
a solution please share. Thanks!

Hey Jason,
Your best bet is to do all the editing you need prior to
encoding. Forgive me if this is a little condescending, but for our
company, the encode to .flv format is the penultimate/final stage
of production.
I can't be sure, but I believe a program such as preniere or
after effects has good integration with Flash - you could output
directly to .flv
In terms of merging two .flvs, you're right - the options are
limited. You can either redo your edit (tricky for long sequences)
and re-encode, or alternatively code something to stick the two
flvs together...very heath robinson, i know!

FLV file not showing up on page

I am a novice with Dreamweaver. I created a site several
years ago using just Contribute 2. Yesterday I used Adobe Media
Encoder to encode some QTs to FLV (.f4v) files using a preset for
Flash 8 compatible FLV files. I created a completely new html page
in Dreamweaver and inserted the FLV file onto the page. When I use
"live view" the page works and plays the FLV file perfectly. Then I
save the file and save to the server. The page updates perfectly
EXCEPT for the flv file. In Firefox it says I need the latest Flash
version, (which I don't) in Safari, it just shows up as a blank
spot on the page, but there is a warning at the bottom of the page
and it allows you to see what the error is.
The browsers "activity" window says:
http://www.veralith.com/FLVPlayer_Progressive.swf
not found
Did part of the code - the FLVplayer - not get uploaded to
the server maybe? What could have gone wrong and how do I fix it. I
did not write special code to get the FLV file to play on the web,
I just used the insert function and thought that Dreamweaver was
going to do the rest for me "behind the scenes."
Any help would be much appreciated. I read as many "help"
files as I could, but I just don't know what I'm searching for. The
website is www.veralith.com. I'm trying to update the "demo" page
by adding about two dozen FLV files, eventually. Right now, there's
only supposed to be one on that page, but it's not showing
up.

Hmm. I just did a test with CS3 and it did exactly that.
1. Created a new HTML page and saved it in the defined site
folder
2. Insert->Media->Flash Video
3. Browse to the .flv file (also in the local site)
4. Chose a skin
5. [OK]
6. Save
A dialog box appeared informing me that it created a Scripts
folder and
that I should upload that folder to my server.
There are now two .swf files in the same folder as the new
.html file.
They were not there before.
1. FLVPlayer_Progressive.swf
2. Clear_Skin_1.swf

Video Freezes when overriding flv files on FMS server

I have an flash application that captures a web cam video stream and stores it on the FMS server.
I notice when I create a brand new video, and store it on my FMS server, it works fine.
When I make another video and my application overrides the file with the new video, this is where I get problems.
When I download the flv file from the FMS server, and I play it locally it plays fine, but the timeline is weird.
The web player freezes the video during that first 15 seconds.
A 30 second video, will have a time line of like 45 seconds, the local flv player is smart enough to skip over the paused part of the video.
You will see it skip over the timeline to the good video (from 0sec to 15 secs). The web player freezes the video during that first 15 seconds.
Any clues that I described that makes you know what is going on?

Great that gives me a big clue, which asc file do you think I need to look in?

How to create Live and Archive Streaming URLs??

Hello Pros,
I am new to QT Streaming Server, and how it is setup and delivered. Please take it easy on me. Here are my questions.
Our school has been using Helix (Real) Server to deliver some video content via Live/Archive streaming video. The school will be changing a format to QuickTime Streaming server to move away from Real. We would like to deliver MPEG4 file via Live Streaming and archive. We set up QT Streaming Server and we can deliver video now.
How do you create and display URLs on a webpage to share live and archive movies? In RealServer, you can list URLs with live and archive, and RealPlayer opens separately and play movie. The videos are lectures so the website will have list of lecture links as we record every week.
If I click this link, a RealPlayer opens and start playing. Currently, I know that “sdp” file is assigned under RealPlayer. When I changed it to QuickTime Player, the player does not open to play movie. Is there way for me to setup URL to open it in external player? We are not interested in making the movie playable inside webpage. We would like to let viewers have option to stretch the movie player to view larger image if they wish. Strange thing is that when the live movie is played in RealPlayer, the image size is smaller that what we stream (320x240). How is it possible? I am confused…
How about archived streaming URLs? I have seen sites with embedded movie in the webpage, but how do you make links that when a viewer click the URL, it will start QuickTime Player externally instead of open it in new webpage? Is this possible? In RealServer, you can use “ramgen” code in a part of URL to open RealPlayer to play a movie.
Any help will be appreciated it.
Thank you.

.FLV files ..why do some play in HTML and others don't?

hi,
I am using dreamweaver 8 to embed 'FLV videos into html
webpages.
the problem is that when I embed and test some flv files, the
player shows up on the page and the videos play fine,
but when I try with a couple of other flv files, these files
do not work - a blank screen shows up (though when I right-click on
the screen where the video player is supposed to be, the flash
drop-down menu appears).
I know that the Size of the files is not why these files are
not working, and I have the latest version of flash player
installed. Also, I'm sure I have not made a mistake in the code,
and I suspect that it is something to do with difference/s in the
files themselves... ?
If you need any further info, please let me know.
this is quite frustrating - so please help.
thank you.

wutronic,
Maybe the following bits from the following Adobe page may be relevant:
Considerations
You can use the Live Corners feature multiple times on a corner, and modify either the radius or the corner style. However, if an associated anchor point in the corner is dragged or manipulated in such a way that the roundness is lost, then the widget will no longer appear for that corner.
Maximum Angle Limit
Users have the option to hide the Live Corners widget
for corner angles greater than a specified value. You can specify this value in the Preferences
> Selection & Anchor Display
> Hide Corner Widget
for angles greater than field.

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!

Problem Inserting Flash Video (flv) File into Site

Hi -
I'm having problems inserting a Flash Video (.flv) into my webpage. I'm using Dreamweaver 8.
I'm going to: Insert - Media - Flash Video, browsing to the .flv file that's in my local site folder, entering the settings.
In Dreamweaver, there's a big gray box w/ flv icon in the middle. But when I go to preview, the screen is empty, no video.
I'm creating the .flv file w/ Screen Mimic (a screen capture recording software). This could be a problem w/ the Screen Mimic file because I have no problem inserting other flv files supplied to me by others. This is the first video that I've made that I'm trying to insert.
If anyone has any suggestions, I would be most appreciative.
thanks!
Stacey Stanley

This could be a problem w/ the Screen Mimic file because I have no problem inserting other flv files supplied to me by others.
That would my guess too. Here are few other things to consider:
1) Does your FLV filename contain any spaces or special characters? If so, rename it without spaces as these can cause problems.
2) Output Screen Mimic project to a QuickTime MOV file. Then use Adobe Flash Encoder to convert the MOV to FLV.
3) When you tested your page, was it a live page on remote server? Did you upload the page and all supporting files to server (Scripts folder, SWF, FLV...)?

How to control framerate in f4v/flv files in a Build / Flash process?

I am quite new to Encore and would kindly ask for an advice.
I am trying to build Flash material from projects, to be played from local PC, not necessary to be used as internet stream. In the final material I just run "index.html" and it plays in my local browser, say Google Chrome. I need that the generated f4v / flv video clips to be rendered in high quality (usually 1280x720 progressive) with framerates as high as 30 fps or 60 fps. Suppose I load in Encore CS5 as asset an AVC mp4 clip rendered with 60fps. I select preset "1280x720 Widescreen High Quality". When executing "Build / Flash..." Encore produces a flv / f4v file with 25 fps. I cannot find where to control this aspect, I would like to endup with a f4v / flv clip with same framerate as the asset, in this case 60fps. Or at least 30fps. Any idea where to control this? I do not find any controls in Encore regarding this setting. Encore simply outputs 25fps flv clips, and sometime 15fps clips (I could not find out why 15fps...). Is there a way to force Encore to output flv clips with same framerate as the original asset?
Thanks in advance!

Thank you, Stan, for looking at this problem.
Yes indeed, Flash output in Encore is limited in many ways. I have done some experimenting now. It seemes I have found a nice application for Flash, but this application was not forseen by the developers of Encore, thus it is only poorly implemented. Unfortunately. Let me explain.
I produce multimedia material (video clips with film footage, still pictures & some effects) to be watched on PC with large screens or on PC & projector. Thus I need HD resolutions. At large resolution effects may sometimes not be perceived to run smoothly unless the video clips are rendered with high framerates. A trivial example would be rolling vertical credits at end of a video clip. When the clip is rendered with 25fps or lower you need to make the credits roll to run very slowly, otherwise the rolling down looks not smooth. Smoothiness gets better with material rendered at 29,97fps or 59,94 fps. I expected Encore would keep the framerate of the original asset when transcoding to Flash f4v / flv. This does not happen. I input assets (carefully observing the accepted input formats you mentioned) with high framerate, whereas Encore produced 25fps f4v files out of them. Unfortunately DVD formats have too low resolution for my intend and BR disks are not very popular where I live. I discovered that delivering material in Flash, to be played as an off-line website from local PC in the default browser - this would be a very nice solution. Unless Encore would perform better for this job. Probably it was simply not designed for this.
My first surprise was that I ended with 25fps f4v material. Trying to change this in Project Settings was not possible. Project was started in PAL and this option was now greyed out. Ok, I started a new project from the scratch as NTSC material, now at least the generated f4v files feature 29,97 fps instead of 25 fps, which would be acceptable. Unless...
The Flash transcoding machine of Encore drastically lowers bitrate for the generated f4v / flv files. I believe somewhere near 4Mbps (but may vary, I have not tested thoroughly). This can be ok for 360p material or lower resolution, or for watching video on youtube, but for HD resolution the effects look very bad and they do not run smooth at such low bitrate. I also noticed there is a problem with the Flash Player. The same generated (poor) f4v palyed in VLC or WMP looks much better than when played with Adobe Flash Player. Not to speak about difference between playing the original asset at 59,94fps with VLC versus playing the generated f4v (25fps) with Adobe Flash Player - here the difference is enormous!
It seemes I had some unrealistic expectations from Encore. I realy like the menus one can design with it, I like the possibility to build the project as Flash, but the results are quite poor. I need to look for an alternative solution.
When issuing the first post I just hoped I was doing something wrong...

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.

If issue of corrupt file after cmd line not in GUI mode. Are you using some automation to copy/paste output flv to someother location?
AFAIK, after placing stop command, FMLE took some time to write proper EOF in FLV. wait ~10 sec for FMLE to complete file writing process and than play in FLV PLayer.
I tried manually with steps you mentioned and it's working fine for me.I playerd file in Applian Flash PLayer. "http://www.applian.com/flvplayer/"

Viewing .FLV Files

Hello Everyone,
I have a few questions regarding the "YouTube" scenario:
1. When a video file is uploaded to youtube, does the flv
file created call the original video in? In other words, is the
original video live on the server?
2. My understanding of .FLV files is that they can only be
viewed on a page via a .SWF file. True? Are there other ways to
view a .FLV file on
(embedded) a page?
TIA,
Greg

Hi
1...I'm not familiar with youtube's methods, but it would be
logical to suppose that any file you upload to a 'public server'
will be accessable by anyone, therefore each instance will be a
live preview of the original. And if its not 'LIVE' on the server
how would anyone know it exsisted?
A swf alone cannot play .flv's even this needs a 'player',
such as the very basic Video object in Flash to the fuller featured
FLVPlayback component. .flv's can be viewed with 3rd party Desktop
apps such as FlashStreamWorks player
FLVPlayer
Check out youtube info maybe they have .flv related
documentation on how to use.
Hope it helps

FLV file won't play vid and audio for more than 3 secs

that's the error i get, and supposedly ffmpeg should be able to handle this conversion

...so i have QT Pro, and it plays the vid and audio for 3 secs and then only plays video. I'd like to be able to use the vid and import it into iMovie. That's what I'm going for...
...suggestions

It seems that I can't login to the developer forums. I'm in the university program and when I try to login to apples developer forums I'll always be redirected to the login screen.
