flash flv codec

andy

isnt sorenson using some vp6 codec in their flash video codec....??

maybe you mean macromedia...
yes, they use VP6 from on2.

You can get the VP6 plugin for the latest version of Sorenson Squeeze. Some people prefer Squeeze over On2 Flix. I've never tried Squeeze.

Is it possible to convert a .flv file to AVI or MP4

Yes.  I'm currently using eRightSoft's transcoder, Super, for such purposes.

SUPER.html

quot; The download size is 18 MBytes, and comes with all windows compiled versions of ffmpeg, mencoder, mplayer, x264, ffmpeg2theora and the libavcodec library.quot;quot;

Mmm...does that mean that it installs all those codecs/players? If so, is there  more barebones alternative to just convert FLV to HuffYUv avi?

afaik you can do it with mencoder 'simply' from cli.

Care to expand on this? I never used mencoder.

something like
mencoder file.flv -o file.avi -oac mp3lame -lameopts cbr:br=128 -ovc xvid -xvidencopts bitrate=500
could just work...

mencoder compiles
mplayer-win32.php

I'm trying to encode to huffyuv, not xvid, can mencoder do that?

Does it? Little_Dragon: could you please answer my question about Super?

Converting FLV with MEncoder to x264 or XviD is easy to do  

Unfortunately audio/video get unsynchron in some cases  
But might be a problem with my specific FLV file...

I'm trying Super right now and other than registering a bunch of filters (nothing that can't be solved by uninstalling it and reinstalling ffdshow I guess), it seems to be ok. Weird thing: even though I selected huffyuv as video codec and pcm wav as audio codec, I have to select bitrates. I have no idea if it respects them in this case. Also, contrary to video size and aspect ratio, I have to manually select a framerate .

Yes, mencoder can encode your video to huffyuv, even in the yv12 colour space. See mencoder manpage
Code:
mencoder ... -ovc lavc -lavcopts vcodec=huffyuv -oac ...
for yv12
Code:
mencoder ... -ovc lavc -lavcopts vcodec=ffvhuff:vstrict=-2 -oac ...
More options to set:
Code:      pred  (for HuffYUV)     0    left prediction     1    plane/gradient prediction     2    median prediction
Add the option to the other lavcopts with a ':' inbetween

Code:
mencoder .. -ovc lavc -lavcopts vcodec=ffvhuff:vsctrict=-2:ped=2 -oac ...

Yes, it installs copies of all that stuff, into subfolders under Super.

ffmpeg

ffmpeg-doc.html#SEC16

how is this conversion in ffmpeg and mplayer possible if the .flv contains vp6 video?

you can do it with mencoder using dll's

Hello,
I have a FLV video which I cannot convert to anything usable. I started a thread for my problem, but haven't got any answer. Sorry for crossposting, but I haven't found this discussion before.
I tried almost everything there is, but without success. The file plays in standard flash web plugin and also in FLV Player. But if I try it in MPC, I only get sound (MP3). I also registred Gabest's DirectShow splitter and opened the FLV file in Graphedit. But the splitter only has audio output pin, there is no video.
So now I found your advices here and I wanted to try mencoder. I downloaded the VP6VfW.DLL and put it in the same folder as mencoder.exe. Then I tried command line

Code:
mencoder input.flv -o output.flv -nosound -ovc lavc -lavcopts vcodec=huffyuv
After some time mencoder crashes, I found in the output this:

Code:
VIDEO: 0x0 0bpp 30.333 fps 0.0 kbps
filefmt: 35 fourcc:0x4
Do you have any idea what is mencoder trying to tell me? Do I have to load the VP6 DLL somehow? Please help me, I'm going mad.  

Thanks,
Vlada

For me MEncoder does the job...

Are you sure you use an up-to-date version of MEncoder ???BTW: MEnocder won't load any DLLs, excepts the Codec package from quot;codecsquot; subfolder
