Join FLV

[forzainter80]

Hello, I have a problem that got me stuck for all last week!

I would like to know if it exists any software that allow me to merge or join two different .flv files; the software must be usable by command line (no GUI) in order to be embedded in external application. I tried ffmpeg and mencoder but they didnt produce any playable .flv, or maybe i just dont know them well enough.

I also would like to avoid re-convert .flv to other format before joining them and re-convert in flv.

Thank you all!!

I removed the request guide topic so moved your post here.

How do you use ffmpeg? what commands?

Macromedia Flash Proffesional I think can join but it wont be that easy to embedd...

Hello Baldrink!

Thank you for moving my post in the right place!

I tried to use this:

ffmpeg -i first.flv -i second.flv third.flv

It just gives a flv with the content of the first.flv.
I also tried to use in windows:
copy /b first.flv + second.flv third.flv
and then reencode third.flv with ffmpeg but the result is the same

what syntax would you write using ffmpeg?
Thanks again a lot!!!

Good luck. Unless all of the files have exactly the same resolution, bitrate, frame speed, etc, it won't work. You can try Mencoder


Mencoder -o Output.flv -oac copy -ovc copy file1.flv file2.flv file3.flv

Already tried, the result file just plays the first .flv (

The files do have the same characteristics since I tried to concat the same file after giving it a different names. So it seems there's no solution....

thanks anyway

[Soopafresh]

ffmpeg -i file1.flv -vcodec rawvideo -acodec pcm_16le file1.avi
ffmpeg -i file2.flv -vcodec rawvideo -acodec pcm_16le file2.avi

mencoder -o output.avi -oac copy -ovc copy -noskip file1.avi file2.avi



Then, encode the result back to flv

I got this message Unknown audio codec 'pmc_16le' while converting to avi

Seems like i have something missing, can I use some other codec?

[Soopafresh]

Probably your version of ffmpeg. http://tirnanog.fate.jp/mirror/ffmpeg/ffmpeg.rev6199.7z

You might need pthreadgc2.dll in the same folder :

Thanks Soopafresh,

at the end Ive been able to make the operation by using just mencoder! It makes the job in a unique command line since it is allowed to have more than one input file!

Thank you!

flvjoin.exe that is shipped along with Movica should do the trick for you.
