Step 2: Configuring ffdshow

We must now configure ffdshow so that VirtualDubMod (and any AVI supporting software) will be able to open up the AVI file produced by FLV Extract (which uses the FLV1/FLV4 codec).

Download ffdshow and start the installation. Click "Next" until you get to the "Select Components" screen, and make sure you select the "VFW interface" option. Press "Next" to continue.

When you reach the "Select Additional Tasks" screen, it will now allow you to select which codecs ffdshow will decode for you (if you already have ffdshow installed, the current selected decoders will be shown). Although the settings here won't actually affect the VFW codec configuration needed for VirtualDubMod, it might be worth selecting the "FLV1", "VP5/VP6" settings for video and "MP3" for audio, which will then allow playback of the extracted AVI file in multimedia players like Media Player Classic or Windows Media Player. In any case, there will be a chance to change these settings after the installation.

Press "Next" and then "Install" to start the installation. Once it is done, the follow screen will appear. Select the options as shown below (run video and VFW decoder configuration) and press "Finish" to complete the install.

The "ffdshow video decoder configuration" and "ffdshow video encoder configuration" windows should now have opened up (check the titles of the windows to tell which is which). In the "ffdshow video decoder configuration" program, select "Codecs" on the left hand side, make sure the "libavcodec" option is selected for both "VP6F" and "FLV1" as shown below and then press "Apply" and then "OK" to close this window. This should now allow you to playback the extracted AVI file in most multimedia/Directshow players.

ffdshow video decoder configuration: VP6F

ffdshow video decoder configuration: FLV1

In the "ffdshow video encoder configuration" window, click on the "Decoder" tab and select "Codecs" on the left hand side.

ffdshow video encoder configuration: Codecs

Again, make sure the "libavcodec" option is selected for both "VP6F" and "FLV1", press "Apply" and then "OK" to close this window. This should now allow you open the extracted AVI file in VirtualDubMod.

nice post! It works for me :) Only the quality from mine movie (got it from video.google) is 320 by 240. Someone knows how2 give mine movie some better quality?

I don't have the streams menu / stream list option in virtual dub, can anybody help me out? I'm having to convert mp3 to wav in order to get sound on my outputs thus bigger than needed file sizes. Please help me out if can.

I've sorted it myself, turns out I was using a later version (1.6) where this function has been dropped.

hatemailme: The guide uses VirtualDubMod (which has the "Stream" menu), not VirtualDub (which has the "Audio" menu, with similar functionalities).

Nice guide, but the latest version of FLVextract is telling me that my .flv file uses 'Nellymoser' audio which can't be decoded. How do I extract the nellymoser audio from my FLV fle?

Hi there, i followed this to the tee but seem to be having trouble merging two avi files together now because of the audio. VirtualDub says that the sample rate is different and VirtualDubMod says that the audio has different data formats, either way i am stuck, any ideas? Thanks in advance Rob

I use a totally different way That is completely LOSSLESS .Flv conversion to .Avi with Virtual Dub Mod ,By enclosing the .flv into an Avisynth envelope. Then then Virtualdub or Virtualdub Mod will read it as if it was an avi . then you can edit the flv ,then save it to ANY format and there will never be any audio synch problem like the way listed here...its all done with not going into the audio stream or anything ! you can use this method to use a lot of formats into Avi.. like MOV,SWF, and tons more formats..try it ... this is not my specialty but it so easy to use virtual dub for everything ,I had to post this response....for the guy that wants to convert the videos from direct upload from youtube that has the stupid nellymoser audio codec this way will not work for nellymoser...but the way to do that in which i had success is to convert the nellymoser audio to wave , then mux it in with vdub ...thats all....... The End - :) Jayson

I have never used Avisynth, how did you enclose the .flv into an Avisynth envelope?

Works a treat! Thanks very much, has solved a long-standing problem for me :-)
