Commercial Detection

[pancapangrawit]

I think Dai's idea is good, might be a bit complicated to implement, though.

A bit simpler but still cool might be, to make 'play' become 'skip' every time, when we are within a block, which comskip has identified as commercial (the ones greyed out in the time-line).

I guess the simplest, yet still functional would be, to make play mean skip any time when a video is allready playing and a comskip file exists.

Hello,

where can I down load the comskip detection? Is it a plugin or included in the lastest version fo the build? I couldn't find it in the download section

Thanks!

comskip is a 3rd party app. i have updated the first post in this thread to point to the latest comskip by Jere_Jones.

In future i'll update the first post to point to the latest binary,

Cheers,
Colin.

It's been awhile, but I've finally put up another version.  0.61 is available here.

It adds:
* a command line argument to select the ini file
* min_show_segment_length to ini file
* dictionary file for show/commercial substring matching
* massive improvements on logo detection to reduce false positives
* aspect ratio as a detection method

Enjoy,
Jere

Sounds great, Jere_Jones, can't wait to try it - but I'm out for a week.

Thanks

commercial detection has something to do with special (maybe hidden) scanlines in TV broadcast or is based on something else probably useful to people in all countries?

what is the concept behind commercial detection?

[Jere_Jones]

ComSkip looks for things that are plainly visible.  I wish there was some secret code that was sent to indicate show or commercial, but the sad truth is we have to look at things like black frames, the presence of a logo, scene change rate, etc. to determine if a given frame is a part of a show or a commercial.

This link explains how an older version of comskip worked and may explain a couple things better for you.

I just installed subversion and grabbed all the latest source, but I can't get it to build completely. Libmpeg2 builds fine. However comskip is missing two files:

config.h
strings.h

There is a config.h inthe libmpeg2\vc++ path, is that the one to use? I don't see a strings.h anywhere on my hard drive. What am I doing wrong? I am using Visual Studio 2003 to build.

Thanks.

[Jere_Jones]

The config.h is located in the libmpeg2/include directory.
The strings.h should come with Visual Studio 6.

Thanks Jere.  I will try and build it on the other machine that has VC6 installed.

Update: I had to add the file comskip.c to the comskip project to get it to link, but it did end up building in VC6. Thanks Jere.
