Comment (by warpme):

 Hi,

 This is excellent idea as here in Poland we have exactly the same
 regulation and by this logo detection totally fails in Poland for me.

 I remember, I asked for feature of defining logo placement in algorithm 5
 or 6 years ago...  now I see You implemented this and this is fantastic.

 I applied Your patch to current master, add in DB settings params as You
 listed in this ticket and tried commflaging.
 Test was on SD channel where logo is in right upper cornet (place is quite
 similar to mkv You provided; pls see yellow "16" in
 http://pasteall.org/pic/4519418035b37f4ae264eeac9152d83d).

 commflag cmd line is following:

 {{{
 mythcommflag --loglevel debug --verbose commflag --jobid 102750
 --outputfile /var/log/ --outputmethod full --logpath /var/log/
 }}}

 Unfortunately in /var/log/mythcommflag log I see:

 {{{
 2018-10-26 20:45:01.094213 I [26042/26042] CoreContext

 (714,570), bottomright (5,5), pixelsInMask (0). Not within specified
 limits.
 2018-10-26 20:45:01.100984 N [26042/26042] CoreContext
 ClassicLogoDetector.cpp:277 (searchForLogo) - No suitable logo area found.
 }}}

 so probably DB params are wrong or I'm doing wrongly something else...

 BTW: is there a way to get better logo detection debugging (or losing
 whole detection process)?
