Description
This ticket is related to the PR : https://github.com/MythTV/mythtv/pull/172
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

To see how and where the logo is detected, you can apply the diff on my branch here : https://github.com/hamelg/mythtv/tree/gha-debug
It comes from this patch : https://code.mythtv.org/trac/attachment/ticket/12308/mcf-display-debug.patch
Have you set CommDetectLogoSamplesNeeded and CommDetectLogoSampleSpacing well ?
comment:3 Changed 6 years ago by
Ok, I merged all commflag sources from Your gha-debug to current master and recompile.
DB settings seems to be OK (IMHO)
mysql> select * from settings where value like "CommDetect%"; +---------------------------------+------+----------+ | value | data | hostname | +---------------------------------+------+----------+ | CommDetectLogoBorder | 64 | NULL | | CommDetectLogoGoodEdgeThreshold | 0.80 | NULL | | CommDetectLogoHeightRatio | 8 | NULL | | CommDetectLogoLocation | NE | NULL | | CommDetectLogoSamplesNeeded | 240 | NULL | | CommDetectLogoSampleSpacing | 15 | NULL | | CommDetectLogoWidthRatio | 6 | NULL | | CommDetectMaxCommBreakLength | 660 | mythtv | +---------------------------------+------+----------+ 8 rows in set (0.00 sec)
Next I launched commflag on 1080i test recording (first 100MB of test recording is here http://warped.inet2.org/sample8.ts)

and many more lines of such error
this "-1" errors I have also with unpatched commflag - so I suspect issue is maybe ffmpeg resync related. I'm curious what Your's commflag will show on this recording....
By curiosity I tried patched commflag on 576i recording and results are the same :-(

I downloaded your sample.
I cut the 1st minute :
$ ffmpeg -i sample8.ts -vcodec copy -acodec copy -ss 00:01:00 z.ts
Then I flagged with :
$ cat mythcommflag-override2 CommDetectLogoSamplesNeeded=30 CommDetectLogoSampleSpacing=2 commDetectLogoLocation=NE commDetectLogoWidthRatio=6 commDetectLogoHeightRatio=8 CommDetectLogoBorder=64 CommercialSkipMethod=4 $ mythcommflag/mythcommflag --noprogress -v commflag:debug --override-settings-file mythcommflag-override2 --method 4 --skipdb --outputmethod full --outputfile output.txt -f ./z.ts
And it works !
To understand the meaning of the parameters and stats in the output file, reading the code and resources below should help :
- https://www.mythtv.org/wiki/Mythcommflag
- https://github.com/MythTV/mythtv/blob/master/mythtv/programs/mythcommflag/README.txt
- https://www.mythtv.org/wiki/Commercial_detection
You get -1 everywhere in output file because you have selected the logo method only. I have tested other methods and combinations, method=4 is the most reliable if a logo is available.
To enable the debug mode, you must uncomment
#define SHOW_DEBUG_WIN
in commercial_debug.h and recompile.

Thx for replay. I'm trying to exactly replicate steeps You are doing:
[root@mythtv ~]# cat /etc/mythcommflag-override2 CommDetectLogoSamplesNeeded=30 CommDetectLogoSampleSpacing=2 commDetectLogoLocation=NE commDetectLogoWidthRatio=6 commDetectLogoHeightRatio=8 CommDetectLogoBorder=64 CommercialSkipMethod=4
Next I launched commflaging exactly as You are doing:
mythcommflag --noprogress -v commflag:debug --override-settings-file /etc/mythcommflag-override2 --method 4 --skipdb --outputmethod full --outputfile /var/log/output.txt -f /myth/tv/23809_20181025181500.ts
console output is following:
[root@mythtv etc]# mythcommflag --noprogress -v commflag:debug --override-settings-file /etc/mythcommflag-override2 --method 4 --skipdb --outputmethod full --outputfile /var/log/output.txt -f /myth/tv/23809_20181025181500.ts

I'm not sure - is this OK (expected)?
I tried commflaging with first 15min of recording trimmed via ffmpeg (exactly like You done):
ffmpeg -i /myth/tv/23809_20181025181500.ts -vcodec copy -acodec copy -ss 00:15:00 /myth/tv/23809_20181025181500-1.ts
Results are the same :-(
Also I tried to recompile with #define SHOW_DEBUG_WIN but launching commflag gives me segfault. Segfault trace is following:
----Proces trace------------------------------------------------------
generally: I scratching my head why commflaging on my recording is working OK for You but not for me?
I'm on current master (as of g2ce3cd7) with programs/commflag sources replaced to Your repo.

I'm scratching my head why comflaging on my recording works ok for You but not for me? My comflag is based on current master with programs/comflag sources dir replaced to dir from your repo. Maybe I should use your code differently?
pls advise

Ah - one remark: console log in comment#5 is from ffmpeg trimmed recording. Thats why You see only 40% of progress.

Replay exactly my test case on your sample, and you'll see it works. The logo detection works in 2 steps :
- 1st : logo searching on a sample : If you see "No suitable logo area found." in logs, this step has failed and the flagging will not work.
- 2nd : Apply the mask built at 1st step to check if the logo is displayed or not on each frame of the video.
The 2 params CommDetectLogoSamplesNeeded and CommDetectLogoSampleSpacing are very important at 1st step and must be set according the video length. They determine the sample used to search the logo.
CommDetectLogoSamplesNeeded=30 CommDetectLogoSampleSpacing=2
means look for logo every 2s, 30 times = It scans the first 60s of the video. It needs a success threshold to decide if a logo has been detected or not (see ClassicLogoDetector::searchForLogo() in ClassicLogoDetector.cpp)

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

may You pls provide here Your log+settings from Your successful run on my sample? how it is possible that the same code+sample+settings gives different results...
comment:10 Changed 6 years ago by
Replay the same steps on the sample z.ts.
You get z.ts by removing the 1mn from sample8.ts with ffmpeg utility.
$ ffmpeg -i /var/http/sample8.ts -vcodec copy -acodec copy -ss 00:01:00 z.ts $ mythcommflag --noprogress -v commflag:debug --override-settings-file /etc/mythcommflag-override2 --method 4 --skipdb --outputmethod full --outputfile /var/log/output.txt -f ./z.ts

Looking on Your logs: You are using v29 while I'm on master.
Sad You are not mentioned this in our all conversation here, so I'm wasting my time trying to understand where root issue is....
Its looks like master has regression in commflag as there is clearly difference between Your results and mine.
comment:14 Changed 6 years ago by
You don't waste your time, you will be happy when you'll enable the ad-breaks skip automatically :) The commflags settings require some times to get results.
The logo flag detection works in the branch master : to convince you, try it with my sample [1] [2].
I tested your sample z.ts with branch master. The different behavior comes from your sample.
- In v29 : It correctly detects the frame rate.
- In v30 : For unknown reason, the new libav detects a wrong frame rate at 50/s. With my sample the frame rate detected is ok. You can see that if you enable the libav logs (-v libav).
So, If you modify the setup according that (CommDetectLogoSamplesNeeded=15), It works with your sample [3].

It still not works for me at current master.
Are You using official mythtv repo?
Here is what I'm receiving trying to build exactly Your version of mythcommflag (v30-Pre-832-g4e207477be-dirty from Your logs)
git checkout 4e207477be error: pathspec '4e207477be' did not match any file(s) known to git.
eh....
comment:16 Changed 6 years ago by
I've just pushed 4e207477be in master. It should be ok now. But there is no modif, just merged gha-logo2 (the PR) and gha-debug.
comment:17 Changed 6 years ago by
Well - lest synchronise terminology:
what you mentioned as "in mater" isn't master in terminology mythtv devs nor me nor mythtv users.
It should be called "my repo branch master". If You want to successfully include Your PR to myth code, it should:
1.pass some testing on _official_ myth code base
2.review with myth devs regarding myth coding standards+implementatoin correctnes (i.e. nor leading to regressions in other parts of code)
You are now in pahse1
While I understand that in development phase it might be easier to do thing initially on developer fork - but if development is engaging time of other persons - good collaboration requires proper communication.. . Since our last few exchanges I'm feeling constantly like person not informed correctly.
So I propose following:
1.You will demonstrate You PR code works ok on _official_ myth master. I'll be then co-work with You to move forward with Your code inclusion into master
2.You will choose not doing 1\ and then I'll stop guessing what You are doing

Ok, let's go back from zero.
Please, build from my repo, branch gha-logo2.
git clone https://github.com/hamelg/mythtv.git git checkout gha-logo2
It contains just the PR and nothing else. You must get :

Get the file sample.ts here : https://app.box.com/s/yhq0yisbalnz37d8wcmh5corsno6e8r3
Then run this test case.
$ cat mythcommflag-override CommDetectLogoSamplesNeeded=30 CommDetectLogoSampleSpacing=2 commDetectLogoLocation=NE commDetectLogoWidthRatio=6 commDetectLogoHeightRatio=8 CommDetectLogoBorder=64 CommercialSkipMethod=4 $ mythcommflag --noprogress -v commflag:debug --override-settings-file ./mythcommflag-override --method 4 --skipdb --outputmethod full --outputfile ./output.txt -f ./mysample.ts > mythcommflag.out 2>&1
I put output.txt and mythcommflag.out in attachments.

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