Playing FLV in reverse

Seems that you can't play an flv in reverse? I've searched a
lot but couldn't find a solid answer or any hints to overcome this.
Is this simply impossible (without embedding and reversing the
timeline) or is there a solution out there?

I think the format of the flv does not make this easy...
perhaps not even possible. The only way I could think of attempting
it would be like this:
1. Encode your video to have a keyframe every frame. (This
has implications in terms of quality vs. bitrate). This allows
seeking to each frame for a progressive video (assuming its
completely downloaded).
2. Use the freeware tool FLVMDI (easy to find with google) to
inject metadata for the keyframes. This will give you the timecode
(and byte address - which we don't need here) of every keyframe in
a keyframes.times property of the metadata.
3. use the playheadTime property of the FLVPlayback component
to track the current frame (because all frames are keyframes) as
the index in the array of timecodes in the metadata. When you want
to go backwards, seek to previous keyframes (using the metadata
timecodes) at the fps rate of the flv (also obtainable from the
metadata). You would also have to maintain a paused state after
each seek to prevent the playhead moving forward.
This is a very much a workaround to get over the limitations
(design?) which is that a flv format is not really designed to play
backwards-
I think it could work in principle, but I have no idea how well
it would work in practice
- I haven't tried it. It's all I can think of.

How do I make my Timeline play forward or reverse depending on its current location?

I'm attempting to make a side scrolling site. I have a wide div set up in the main timeline that animates 1000px at a time on the x-coordinate between the labels I have set for each "page".
I would like to click a button and go to the associated label and stop. I am faced with 2 problems:
1. Sometimes this would require the playhead to move in reverse rather than forward.
2. I originally had stop triggers on the timeline under the labels but if I am able to get my first problem fixed these triggers would stop the animatin before reaching the label.
I'm just learning java so I'm guessing I need an if statement and a function.
Example of what I'm trying to figure out:
I want to press work button and play to label "work".
If I'm at label "home" I need to play(); and stop at label "work". If I were at label "blog" I would need to playReverse(); to label "work".
Please help! I've been going looney trying to figure it out!

Thank you for your reply!
My post may have been a little misleading...
I have a navigation bar with 5 items. Home, work, blog, about, contact. My main timeline has a symbol that is 6000px wide. Inside that symbol are individual symbols that make each of these "pages" which are 1000px each. My timeline has animations that last 1.5 secs each and animate the main symbol 1000px on the x dimension to stop on the main stage which is 1000px. Essentially it creates a 5 "page" side scrolling layout. I have the five labels on the timeline starting at 0s with "home", 1.5s labeled "work", 3s labeled "blog"... etc.
I wish to be able to click blog and travel forward or reverse on the timeline and then stop on "blog". Then If you click home you should reverse along the timeline and stop on "home". If I have any stop(); triggers on the timeline it would stop in transition to my target label without reaching it. In addition a generic play(); or playReverse(); doesnt target a specific label which is whats required for my navigation bar.
I need to play forward or reverse from the current location on the timeline and stop when it reaches a specific label. Visually you would be sliding back and forth across the pages as you use the navigation.
Is there a way to do this with variables?
I'm going to try triggers on the timeline like this sym.setVariable("pageValue", "home"); when on the "home" label. sym.setVariable("pageValue", "work"); when on the "work" label.
but then how would I tie that to my buttons?
If I click work and I'm on home I need it to check: var myVariable = sym.getVariable("pageValue"); and then an if or else statement I think? I'm such a noob. I'm trying really hard to grasp it
something like: if pageValue = "home" { sym.play();} else if pageValue = "blog","about","contact" {sym.playReverse} if pageValue = "work" {sym.stop();};
I know there is probably all kinds of syntax errors there but can someone understand what I'm getting at?
to make this even more tricky I am interacting with the stage with an html and css navigation bar that lays over the stage so I need this to be in function style (see code)
function goHome()
javascript:var targetComp = AdobeEdge.getComposition('EDGE-57204389');
 targetComp.getStage().playReverse();
and then call it like this in html
<li><a href="javascript:goHome();" class="three-d">
 Dynamic
 DynamicArtisans
 </a></li>
This works to play the stage in reverse but its not the functionality I need. Any help would be greatly appreciated and a great learning point for me and hopefully others in my situation!

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").

Is there a way to play flv & mkv file formats through media element in windows 8.1 app ?

i am trying to develop a video player so i just thought Is there a way to play flv & mkv file formats through media element in windows 8.1 app ? , coz when i tried media element it is supporting only mp4 & avi formats.

Here is a list of Media Foundation codecs
http://msdn.microsoft.com/en-us/library/windows/desktop/dd757927(v=vs.85).aspx
For the rest of the formats you have you write your own MFT-based codec and ship the codec with your app. See also
implementing a Codec MFT (http://msdn.microsoft.com/en-us/library/windows/desktop/dd757274(v=vs.85).aspx)
Media extensions sample (https://code.msdn.microsoft.com/windowsapps/Media-extensions-sample-7b466096)
MKV and FLV are just container formats, though, you need to survey some video files to see what video codecs are actually in streams and support them one by one. Supporting some proprietary video formats may involve licensing costs from patent holders.

Flash Player 10.2.152.32 won't play FLV file

I seem to be having similar problems to several others here.
I am running Windows XP, SP3, 32 bit on Dell Pentium 4, 2Gigs of RAM, 3.0Gig HD.
Since the March 8, 2011 update I have not been able to play FLV files. Previous to the upgrade, I was able to play these same files.
I have checked - Shockwave Flash Object (VS 8.0.24.0) is apparently installed and enabled, although it DOES NOT show up in the file list (that I can tell at least) in the System32/Macromedia folder. It may be called something else perhaps? These are the files that show as updated on March 8, 2011.
Flash10n.ocx - Active X Control
FlashInstall - text file
FlashUtil10n_ActiveX - application
FlashUtil10n_ActiveX.dll - application extension
Files with previous dates are:
flashplayer.xpt - XPT file, install - text document - dated Feb 17, 2010, NPSWF32.dll - dated Nov. 20, 2007, and NPSWF32_FlashUtil - also dated Nov. 20, 2007.
I can play stuff from YouTube. I am able to see the Flashy thing turn on the link you supplied to others here.
My security is set to "Medium". I have had NO virus issues, and run a VERY tight anti-virus protocol with AVG, AdAware and SpyBot all active, updated either daily (automatically) or weekly (manually).
Should I uninstall and then re-install, so the SFO will be included, or is there a way to retrieve the (apparently) missing Shockwave Flash Object file on its own? This issue has now taken up my entire evening, and I am ready to PERMANENTLY delete Flash from my life!
Thanks,

Hi, you don't need to scream at me. I've been on the Forum 12 hours today and 12 hours yesterday helping users with their problems. This past week I had over 1,000 email notifications in my email account and 90% were from the Flash Player Forum.
And this:Let's try again..........arrrrrrrghhhhhhhhhhhh!!!!
Please don't insult me and act like I don't know what I'm doing or talking about.
The Shockwave Flash Object is not supposed to be in the System32 ...Flash file location. It is never there. It is always in the addons of the browser, it must be since it is the Flash Player Control. Without it and without it being the correct version(which yours is not) Flash Player cannot work! I repeat, Flash Player is a browser plugin and works thru the browser.
The fact that you have a 32bit OS doesn't tell me anything about what browsers you use. I have a 32bit OS, but I use IE6 on one and the other PC I use IE8.
I know you checked some of my posts, I'm not so dumb that I don't recognize my own writing.
Yes, you need to Uninstall and Install again, that is the only way you are going to have the correct SFO Installed.
If you'd tone it down some, I may give you the best way to do that in order to be successful in that.
However, it won't be tonight. Maybe you'll be in a better mood tomorrow.

[SOLVED] VLC no audio, Volume stuck at 0%-5% only when playing FLV

Hello Friends,
I've had this issue for a while, only on one laptop (I run Arch on everything)... VLC will play my .FLV files, video works, playback works but no sound. The volume gets stuck and can only be changed by 5% (If VLC was running before and volume was at 60% I can change to 65 and back to 60. If VLC was closed and I open a FLV file it is always at 0% volume and will only go up to 5%).
I get the following error every time I try to adjust the volume.. Other file-types work fine.

C7: How to play .FLV files on Nokia C7

Can I ask how do you play .FLV files on Nokia C7? I searched for FLV player in the Ovi Store and nothing is returned, whereas on Android Market loads of FLV players are available.

I couldn't find an FLV player either. But you can download freemake video converter from internet. Its really a very good converter and I transfer my vids to C7 only after converting to C7 resolution because it makes the processor to do less work. If you transfer an HD vid directly to phone it will play fine but will cost u battery life. (more processor usage)

How to create a .f4m manifest files to play .FLV files

I typically use .f4v files for my on demand playback media files, however I converted a .mov to a .flv file... How do I create a .f4m and .m3u8 manifest file that plays .flv files? Below is the code I normally use for the .f4m and .m3u8 files. This works great with .f4v files. I also included my player code. What am I doing wrong? The only difference is I'm using a .flv that I didn't use the f4vpp cleaner on.. That shouldn't give me the parse error I'm getting.
022714.f4m is the name of my .f4m Flash manifest file. Below are the contents.

to create a file in appl server you have to use open dataset and close data set..
see the sample code
REPORT zanid_test MESSAGE-ID zz .
parameters: FULLPATH(128) obligatory lower case
 default 'E:\usr\sap\put\file.txt'.
*you change the appl sever path as per your config.
DATA : BEGIN OF list_asc OCCURS 0,
 msg(300) TYPE c,
 END OF list_asc.
start-of-selection.
*---populating data
list_asc-msg = 'abcdefghijkl'. "your sample data
append list_asc.
list_asc-msg = 'faagoaagiagig'. "your sample data
append list_asc.
OPEN DATASET fullpath FOR OUTPUT IN TEXT MODE.
LOOP AT LIST_ASC.
 TRANSFER LIST_ASC-MSG TO fullpath.
 CLEAR LIST_ASC-MSG.
ENDLOOP.
CLOSE DATASET fullpath.
now if you go to appl server , you will find that file in that specified path..
to create a directory yu can go to transaction AL11 and click the 'konfigurieren'button, you then you can specify the directory attibutes to create a directory
and to load a file from your loacl pc to appl server you can use transaction CG3Y also, instead of the abap code.
plz rewrad points if it helps you.

10.5.3: CAN play .flv, 10.5.4 canNOT

i have a bunch of .flv files that would play fine in the quicktime player (i could hear the sound and scrub the video). i could play them in the app called "flash player" but it wouldn't let me scrub the files. vlc would crash when i scrubbed the files, but i could hear the sound.
this worked (playing .flv files in quicktime player) on my macbook pro without quicktime pro installed. strangely, on my desktop mac pro, which also has 10.5.3, it did not work.
i just upgraded the macbook pro to 10.5.4, now .flv files will not play sound in quicktime player, vlc still crashes when i scrub (but does play sound), the app "flash player" won't let me scrub, and i found an app called "swf & flv player" that plays sound and will let me scrub (but not always, sometimes it snaps ahead in time when i scrub).
quicktime player worked best in 10.5.4, what happened when i upgraded? why did it work on my macbook pro, but not the mac pro when using the same system?
why is this so hard to get right? why doesn't all "just work"?
thanks.
marc

Neither OS X nor QuickTime natively allows the playback of .flv content. However, adding Perian to your system

playback. I imagine that at some point in the past, you must have installed Perian on your MBP but not on your Mac Pro.
