Comskip 0.71 posted

[erik]

I have posted comskip 0.71
It can be found here

It contains a description of all tunable parameters and the cvs file format and it has some improvements in aspect ratio recognition.

Have fun!

Do most people think .71 works better than .63? In most show, there is one commercial that comskip does not fully recognize - for me.

I have non-hdtv cable in the US.

Does .71 not recognize a commercial?
If so, send me the log (verbose=10) and indicate the exact frame boundaries of the missed commercial.

Thanks for the new version, but I have trouble understanding the new settings, and how they work. If the defaults don't work, should I make them higher, or lower, or which one's higher or lower, and why are the defaults in the ini different that in the .txt file you included?
These are the ones I mean:

Code:

score_percentile=0.00    ; 0.67
black_percentile=0.005    ;0.0073
logo_threshold=0.70        ;0.75 (0.05 added because of strict)
brightness_jump=200
non_uniformity=20

Should I change my logo_threshold from it's current working value of 83, to 70?
Brightness jump, up or down to detect better, and how can I tell?
non_uniformity=20, up or down? According to the log, uniformity runs from about 48 to 77 or so, is 20 a good number? why? Should it be higher?
What do these do:

Code:

score_percentile=0.00    ; 0.67
black_percentile=0.005    ;0.0073

What do the numbers mean, and again, up or down to improve detection, and is it in the log somewhere I should be looking for these numbers?

Sorry for all the questions, but new stuff without explanation is very confusing.

Please read the previous posts.
The new logo algorithm can recognize weaker logo.s without (many) false positives so you should lower the logo_threshold
YOu can put score_percentile to 0.0 if you always have a logo on shows and not on commercials
Look at the histogram for brightness to understand the black_percentile
non_uniformity is to generate cutpoints at uniform brightness frames (black, blue, white, whatever color), start at 200, if you et too many cut's with a 'u' (see block list in log) lower the value
Defaults shoule be ok.

Is this a release from Jere? I'm more than happy with 6.3, and until I here from him, I'm going to hold on this release IMHO.

[reboot]

I thought score_percentile was for percentage of recording that was show, or roughly 71%. If it's strictly for logo, then I CAN USE 0.00, because all the shows I record, only have a logo during show, and not commercial...except for the odd one, that has a disappearing logo about 5 seconds before a commercial. I could use 0.001 or something for this?

I figured out black_percentile, thanks

I don't see the "u" in the log...which portion should I be looking at?

A couple of things, by my understanding of the way INI files work this

;detect_method=43
detect_method=255

Should be read as the 43 is a comment and 255 is the value. But after several confusing Hours I find that 43 is the value (i.e. the ; is ignored) and that the first of any value is accepted all later values are ignored.

Also in this case:-

;garbagedetect_method=43
detect_method=255

detect_method would be set to 43

Comskip uses very basic code for the ini file. It searches for the first "detect_method=" it can find and then extracts the number following the "=". That's just the way the code is designed.

It should work as you desire if you changed:

Code:

;detect_method=43
detect_method=255

to

Code:

;detect_method!=43
detect_method=255

But it works still no matter how basic the code is

I didn't mean to come across as saying it is bad code. It does exactly what is should do. Or, as you say, "it works." It just isn't full fledged ini parsing code like would be needed to skip comments and such. That's all.

Didn't mean to come across as negative, only helpful.

I am very happy that Jere and the others that have initially written comskip did use 'C' because that's the only language I can realy write software in.
I still have to get used to the 'void' keyword.
So you can gues my age now :o
