Comskip 0.79 build 16 posted:Small bugfixes and improvements

[erik]

happy to hear
I would like to receive some .csv files and the .txt files (reviewed by you for correctness) so I can add them to my reference set.

I sent my CVS and TXT files to you email address 11MB

And I had a look and found a possible mistake made by comskip. :o

Wow,
That was fast. I'm open for suggestions.

LilY0da:
Could you send me a .csv, the comskip.ini and a corrected .txt file so I can have a look?

I'm not sure I kept them, or that I kept shows that would have that format, but I'll check tonight.

I ran more tests after my post and what I found is that if you enable logo detection, and your logo isn't in that very short initial show segment, then it doesn't get detected. Once I removed logo detection, the short initial show is detected OK (however the end commercials don't get detected anymore )
Looks like logo detection supercedes that "short initial segment" detection method.

The comskip.ini file contains the setting
delete_show_after_last_commercial=1
This will instruct comskip to delete anything after the last commercial found.
If you change this to
delete_show_after_last_commercial=0
The last part will not be deleted.

I have the INI file set to delete_show_after_last_commercial=1 should it be 0 or 1?

I found another possible reason for this strange "skip last 2 minutes" behaviour.
I did add a very small 1 frame commercial at the end of the recording to signal the total length of the recording in the edl file, I did the same for the .txt file.
Please try to delete the last 1 frame commercial in the .txt file and see what happens.
if this solves it then i will delete it.

this is the txt file for that show what do I do? I do not see a 1 frame commercial. that is if I am reading it write.

If you want to delete the show after the last commercial it should be
delete_show_after_last_commercial=1

In the example you give

FILE PROCESSING COMPLETE 53852 FRAMES AT 2997
-------------------
1 6724
12474 16429
25140 29935

The last commercial runs till the end of the recording (frame 53852) so no need to add the one frame commercial at the end.

LilY0da:
Indeed there is a link between some of the more advanced algorithms and logo detection. If you disable logo detection some of them get switched off.
I hope I did explain that in the tuning manual.

Could you send me the csv and corrected .txt for such a recording?

Comskipad has three functions

beginpadding=x
endpadding=y

These act the same as the
padding=x
setting in the comskip.ini file where x is the amount of seconds the commercials will be decreased in size at start and end

startLimit=z
acts the same as the
delete_show_before_first_commercial=1
although comskipad allows you to select the maximum size of the part before the first commercial, in comskip its fixed to about 15% of the total recording.

You are right I deleted the last line 40635 53852 and all works. I understand what is going on now. Thanks. What would of keep me from being so confused would be if GBPVR showed that as a commercial skip them I would have seen it and known what was happening. What I did last night was change 53852 to 50852 and now GBPVR shows it as a commercial break.

Thanks for your help!!!
Also the commercial detection has been around 90% accurate on my system now!!! Great job!!!
