Comment (by warpme):

 I tried Your branch ( gha-debug [v30-Pre-3d30b916cfe]) on my sample
 (http://warped.inet2.org/sample8.ts) with settings like this:

 {{{
 cat mythcommflag-override2
 CommDetectLogoSamplesNeeded=30
 CommDetectLogoSampleSpacing=2
 CommDetectLogoLocation=NE
 CommDetectLogoWidthRatio=6
 CommDetectLogoHeightRatio=8
 CommDetectLogoBorder=64
 CommDetectLogoGoodEdgeThreshold=0.80
 CommercialSkipMethod=4
 }}}
  with commandline:

 {{{
 mythcommflag --noprogress -v commflag:debug --override-settings-file /etc
 /mythcommflag-override2 --method 4  --skipdb --outputmethod full
 --outputfile /var/log/output.txt -f /var/http/sample8.ts
 }}}
 and result is:

 {{{
 mythcommflag --noprogress -v commflag:debug --override-settings-file /etc
 /mythcommflag-override2 --method 4  --skipdb --outputmethod full
 --outputfile /var/log/output.txt -f /var/http/sample8.ts
