Changing Dialog-Based Codec Settings Programmatically (avs2avi and On2 VP6)

[Umamio]

I am attempting to perform batch encodes using the On2 VP6 codec, however, using Shodan's excellent method (http://sh0dan.blogspot.com/2006/09/command-line-flash-8-flv-encoding.html) I must set and change the On2 VP6 profiles manually.

I believe I can change On2VP6 profiles programatically by mimicking the registry modifying actions of avs2avi when changing the encoding profile manually by performing a RegQueryValue operation at "HKLM\SOFTWARE\On2 Technologies\VFW Encoder/Decoder Settings\VP62\bSettings" once I've figured out what binary data corresponds to what profile.

However, I cannot determine what exactly avs2avi modifies to set On2 VP6 as the encoder to use, or if I can set this from the command line directly if I know at which position in the list of codecs On2 VP6 appears.

Can anyone help? Or does anyone know how to build a custom avs2avi that restricts its use to a single codec so I don't need to keep having to change it to the correct one?

I do not really know in which section of the forum this belongs

Edit:
I am an idiot. The .conf file in Shodan's method is what stores the profile.

Finally, I have opted to use mencoder rather than ffmpeg as it has support for using VFW dlls (-xvfwopts) to encode and storing profiles to file using vfw2menc, so I don't have to poke around with the windows registry.

In case anyone has a similar problem.
