Convert .flv file

[kol_korivo]

I need to make a .flv file available to mobile device.

We are creating our file with Flash Communication server.

So im trying to convert the .flv file to a .3gp file.

I was able to do so by using the Total Video Converter software, but i have to
remove the audio track to have the file convert.

Is there an alternative solution to convert a .flv file to a mobile enable
file?

IS there a way to change the audio codec that the Flash Communication server
use so i can convert the file ?

Any input is greatly appreciate.

The newest version of total video converter V3.34 supports FLV Nelly
Mosser decoder.

I've successfully used FFMPEG... take a look a it, but it can handle both formats, and the documentation is well explained..

Could you give me any hits on how this works?

Ive downloaded the "ffmpeg-0.4.9-pre1.tar.tar" but im not to sure what to do with it!

There is no install or such.

Thanx for any info

Hi

Hope Im not changing the subject but whats the best way to convert a 3gpp file into a flv file? I assume that flv is a common file type which would work on most browsers, thanks a lot...h

i am converting litterally "everything" to "everything" and last night i found
something call SUPER (simplified universal player encoder renderer.... only the
french can come up with such a name!!!!) ...it is built on top of ffmpeg .....

[sdrouin]

oohh...about SUPER.....it's also super free

[kol_korivo]

cool!
i'll take a super look at it...:)

[kol_korivo]

yeah, its looking super good indeed!
But i still have problem with the audio codec!

Not a single settings seems to be working right.

Got any tips on this?

kol_korivo...can you refresh me on the specifics of the problem(s) you have
with audio? don't forget that 3gpp and 3gpp2 are fairly new and present
different sets of problems for different sets of handsets....in the meantime
what I did is that I converted with SUPER to a quicktime format using the aac
codec and then used the flash 8 video exporter to convert to flv (which is what
I needed...)...i have a nokia development platform here along with flash 8 pro
so if you tell me more I'll run some tests....

[kol_korivo]

Ok, heres what im trying to do.

On our web site, we have the flash communication server steup.
From the flash server, were are creating .flv file.

I need to make these .flv file available from a portable handset.

So my thinking is, "i need to convert the .flv file to a 3gp file!"

I was able to convert the video but not the audio.
I was not able to find the right "setup" to convert the audio and video from
the .flv to a 3gp.

So, is this possible at all ?
Any other solution that i overlooked?

Thanx a lot for the follow-up

ok now i got your info. I recently converted a bunch of our video to 3gp and
had sound problems. There is several elements that need to be considered.

1) What codec do you use? mpeg-4 or h.264 or both?
2) what handsets you want to target? you cannot expect to target all
handsets as they all use different players (for example I had to use the nokia
multimedia converter available from the nokia developer site to retain the
audio when i converted from quicktime to 3gp to test on my nokia 6600.
3) one of the newest feature in flash 8 pro is instrinsic support for
handsets so what could be done would be to embed your video directly in the
..swf file and put into the communication server but again that would be for
specific handsets supported in flash 8 (at least you would know which one will
be working as flash 8 provide you, depending on the features you are using in
the swf file, with a list of compatible handsets).
4) How come somone from Macromedia does not help provide an answer to this
thread?

Again my view is that you will not be able to just throw one 3gp file and
expect it to be streamed down to the handset and work....the problem again is
not the protocol but the video player on the handset itself...which depend on
the OS being used and the player compatibility with the 3gp file being
downloaded.

Finally there are opensource applications that allow you convert for several
different handsets directly from your flv....I am currently looking for them
and will come back to you as soon as I find them!!!!

to be continued....

Also I think that FLV files created with FlashCom uses a propietary audio codec, so check this first, how to extract audio track from flv file....

Thanx for your follow up sdrouin

1) About the codec, the output video codec dropdownList only give me 2 choices
for the three possible conversion (3gp nokia/NEC/Siemens, 3gp sony Ericsson,
3g2 Sony Ericsson). Its either mpeg4 or h263.
Both of them failed

If i try to convert my .flv to a .mov, it doesnt work at all with the mpeg-4
codec, but with the h264, the SUPER start the conversion but crash after 1 or 2
sec.

2)About the type of handset , ill take anything that works! Seriously, i cant
target a specific device, i just want to get the video out there. If there is
only a few device that can listen to it, fine by me.

3)Im not too sure about this here. Is the end result would be a .swf file?

4) And yes, somebody for Macromedia should shed some light on this, im sure im
not the only one that is trying to do this, and there will be a lot more in the
near future.

I also heard about this property audio codec, but im pretty sure that flv file
can be decoded.

Anything else?

There are lots of great products out there, I've always used the FLV Converter . It is free and gives me the flexibility of conversion formats that I need to go to all kinds of devices and even video editing software.
