[theora-dev] Using the VP3 ENCODER in a DIRECTSHOW GRAPH wit defined quality and BANDWIDTH - HOW?

[Daniel B. Miller]

so you are using the VFW codec, right?

The codec presently looks in the registry to get the bandwidth parameters.

I would suggest looking at this function (in vp31vfw.cpp):

void registry2settings(COMP_CONFIG &CompConfig)
{
        char vp3settings[120];
        unsigned long size;

<p>Registry_GetEntry(&vp3settings,REG_CSTRING,&size,"strSettings",REGACCESS);

    sscanf( vp3settings,
                "%ld %ld %ld %ld %ld %ld %ld %ld %ld %ld ",
                &CompConfig.TargetBitRate,
                &CompConfig.Quality,
                &CompConfig.KeyFrameDataTarget,
                &CompConfig.AllowDF,
                &CompConfig.QuickCompress,
                &CompConfig.AutoKeyFrameEnabled,
                &CompConfig.AutoKeyFrameThreshold,
                &CompConfig.MinimumDistanceToKeyFrame,
                &CompConfig.ForceKeyFrameEvery,
                &CompConfig.NoiseSensitivity);
}
