Server Side Flash Video Encoding

I looked into server-side video encoding last year and wrote about it on my blog: -

Thanks, interesting article!

Since [url=http://gallery.menalto.com/]Gallery[/url] can use ffmpeg to convert uploaded videos, there is a lot of discussion on their forum about this topic.

This thread [url=http://gallery.menalto.com/node/55500]Convert video to .flv or .swf on upload[/url] is an example.

Also, this guy has a Windows version of ffmpeg available here [url=http://www.flashyourweb.com/filemgmt/index.php]Flashyourweb.com[/url] for those who need it.

psykokwak, I'm interested about your "flv on-the-fly" script to do video streaming using ffmpeg.

If it works, where I can contact you?

thanks

Gallery2 now has transcode :)

" Does anyone know it is possible to encode flv video files in batch server-side (linux server) from other formats? (.mov, .avi, .wmv, .mpg) A php API would be particularily great! "

:S

ust FYI, I released phpVideo 0.2 (with few bug fixes and thumbnailing) available at www.wattz.net. Just thought i would keep you guys updated :-)
:PPPP

Check http://www.effectmatrix.com/total-video-converter/

Should be worth of it !!

:S

ffmpeg can't encode rmvb either...

Yes, it will convert wmv, but only wmv1 & wmv2. Not 3 unfortunately.

@ Jeroen: Actually, On2 just released the Linux version of the engine. I may be switching to that because ffmpeg just isn't working for me

Or you could keep the movie in a folder not on the web and access it through, say, a php script that checks permissions.

Thanks. I'm been doing some research and it seems like that is the consensus. Store the files in the file system with a reference to them in the DB. If anyone else has a good case for storing the files as binary data in a DB I'd be interested to hear it.

Thanks for getting back to me.

If we can't completely hide the controlbar in fullscreen mode .. can we change the opacity then? meaning ... lowering the opacity to around 10 and when the mouse over .. turn it back to 100 ... that way, it will be like pseudo-hiding ..

that might be possible using some command like list files, and you point it to your files directory so he grabs each flv file and place it in the playlist, but i dont know how to do it.

Hmm, does mencoder do serverside encoding? I can't really tell from what I've read.

It seems that On2 engine actually costs around $3000 per year(!) so ffmpeg is the only viable solution for small websites to convert videos SERVER SIDE.
Too bad it only converts from AVI to FLV as far as I know.

The Company Movavi Ltd. just published a serverside SDK named Movavi Flash Engine SDK that cost $ 300 a year or 1000 $ unlimited license.
It supports the conversion of AVI (DivX, XVid), MPEG (1, 2, 4), MP4, 3gp, 3gp2, WMV, MOV (QT), VOB to Flash video using COM technology: C/C++/C#, .NET (Visual Basic), ASP, PHP, Python, Perl, and others.

Hello All Guys,

Hope all are doing well here

I need help for linux server Is there any one who did FLV conversion from WMV file on linux server in PHP

Please let me know if anyone know this

Thanks in advance

Hello everyone

I'd like to add online video encoding to my site, and since many of you are already using open source tools (ffmpeg, mencoder) to convert video files to FLV, I'd like to know where (if) you acquired the licenses to use the patented technologies (MP3, MPEG4, H.264, etc). The ffmpeg FAQ states that the MPEG-LA is one of the autohrities to contact. Are there any others? Are the licenses expensive?

Thanks!

take a look here :

I've download Media Handler Pro dll file which converts the videos formats into desired formats. For instance if you want to convert wmv files into flv then it will convert and upload it and then make thumbnail nail....but the problem in this control is that it only have 5 sec duration. Can any body tell me how to crach it so that I can change its time ellipse.

I was working on a social network that allowed users to upload video and we were on a tight budget so On2 was not an option $3700 per server per year! I also spend some time with opensource ffmpeg (now that they support H.264 for Flash 9) but found it took a lot of time to configure and tweak on a server, also since user upload demand could be sporadic with user generated video sites I did not want to scale out an entire server farm to support encoding as I found one dedicated Linux box (dual processor with 4GB RAM) could only handle about 20-30 simultaneous encoding tasks which meant I needed to develop some type of encoding queue. We finally settled on http://www.fastencoding.com, because they made a very nice XML API available and also had a nice encoding queue. This was very cost effective for us because they have on demand pricing and make up to 10 of their servers available simultaneously for big demand, also they had great presets for all of the mobile formats, PSP, iPOd, iPhone, Zune, 3GP phones etc.

@Jack,

Thanks for the info.

Ffmpeg encoder do large sized files, we code movies on our site http://www.arionmovies.com ,
but 1 Mb/min - to low quality. If you know encoders better like ffmpeg, please tell.

i,
i found after goggling that it is not possible in flash with actionscript to force the Microphone/Camera/NetStream classes to use a codec of your choice.

It is, however, possible to transcode the resulting FLV from the server side to something that uses the 3GP container format and AAC for audio.

I have successfully converted flash media server flv to 3gp with AAC codec that 3gp file is playing fine but it has one major problem that is of audio video synchronization that "video comes first and then audio".

I am using ffmpeg higher version command line tool for this.

how can we do so ?

is there any solution for this problem?

Thanks

Try Sothink Video Encoder Engine. It works for me.
http://www.sothinkmedia.com/flash-video-encoder-command-line/

One of the most impressed advantages is that it supports too many video formats than the popular ones. And you can even add more by yourselves.

hi,
i am using totoal video converter pro command line version to convert my

webcam recorded flv to 3gp formate but small flv i can convert successfully
but in big flv the converted 3gp file loses audio just i can hear i small peace

of audio at the starting of 3gp file when i play it .

any one can give me proper suggestion?

Thanks

hi,

finally the aim is to convert flash media server flv to 3gp that has nellymoser
audio codec using any command line tool.

waiting for your valuable suggestions.

Thanks

Hi,
i want to convert flash media server flv to 3gp using any command line tool.
i download a flv from

http://www.seesmic.com,
http://www.youtube.com,
http://www.audioacrobat.com/learnmore/samples.htm

and try to convert in 3gp using total video converter pro that is

command line and the flv is converted to 3gp successfully and playing

fine,but when i try to convert my flash media server flv to 3gp it converted

successfully but with audio/video synchronization problem that is video is

playing fine but audio comes just only when flv start playing for few

seconds .

when i view matada information of my flv and downloaded flv i looking that

the flv that i downloaded from above website has not

framrate and my flv showing 36.608 fram per second.

i am using flv metada tool to view flv matadata information.

not what to do for proper flv to 3gp conversion and what tool above

websites are using to encode flv?

Thanks

Is there a way to cluster the transcode process.

Hi Everyone,
I want a server side flash video encoder(with on2vp6, H.264 codecs supported). The encoder should also support embedding navigation cue points in the video. Please suggest me the appropriate encoder sdk or command line tool
thanks

There are Desktop tools available for the purpose I mentioned in the above post but i didnt find any except the on2's Flix Engine which costs an arm and a leg.

thanks

Try looking at videohelp and doom9. Those sites are more oriented to video transcoding, whereas these forums are mostly for the JW FLV Media Player.

www.encoding.com is a cost effective solution

Server side video encoding.

http://code.google.com/p/multimedia-conversion/
http://code.google.com/p/jakubiak-mcc/

With a small modification set this server will support cloud encoding.

for the purpose I mentioned in the above post but i didnt find any except the on2's Flix Engine which costs an arm and a leg.

You can also look into a service called "panda". They're a free package that more or less wraps around FFMPEG. Easier to setup and with features such ac queueing.

As to the ON2 Flix engine, this is indeed an option. There's more commercial packages out there, e.g. FlipFactory or Rhozet.
