 My patch allows to spot where to lookup the logo.

 * !CommDetectLogoLocation: Choices include N (North), S (South), E (East),
 W (West). The direction you choose specifies where to lookup the logo.
 * !CommDetectLogoWidthRatio: To specify the maximum width of the logo.
 * !CommDetectLogoHeightRatio: To specify the maximum height of the logo.

 For the french TV channels, the reliable method to flag commercials is by
 logo detection. Unfortunately, the current method works fine if there is a
 only one logo displayed. The CSA is the French public authority of
 regulation of the audio-visual one. It adds another logo to protect
 children against harmful program. Here is a example here ![1], the CSA
 logo is located at the bottom right corner.

 Below is my commercial flagging setup and it works very fine :
 {{{
 CommDetectLogoSamplesNeeded=240
 CommDetectLogoSampleSpacing=15
 CommDetectLogoLocation=NE
 CommDetectLogoWidthRatio=6
 CommDetectLogoHeightRatio=8
 CommDetectLogoBorder=64
 CommDetectLogoGoodEdgeThreshold=0.80
 CommercialSkipMethod=4
 }}}
