Utility: ShowAnalyzer Beta

[Jere_Jones]

Interesting. Thank you for pointing that out. That little feature is amazingly complicated and I guess I ended up getting a little confused. I'll get that fixed.

Not a prob. I've kinda been looking forward to that feature myself and thought I'd give it a swing but it was kinda freakin me out!

I calibrated my capture cards, which involved increasing the brightness by almost 20% above default and now SA is having problems detecting the segments on some shows. Are there any settings I can adjust to compensate or is my only option to lower the brightness until SA can detect the segments again?

Maybe you should be calibrating your playback rather than your recording... I've found the default settings for my hauppauge cards to be pretty darn good.

My display is already calibrated and I used the histogram in FFDshow to calibrate my capture cards. I have a couple of PVR-500's and the default settings had the contrast and brightness way too low.

It seems the problem has more to do with version 0.6 of SA than the settings of the capture cards. I reverted back to 0.5.10 and it detects almost every commericial perfectly. At least for me the newest version of SA isn't anywhere near as accurate as the old one.

I've done the exact same thing. Back to the old version.

Me too... 0.6.0 seemed to miss the last commercial in each segment.. 0.5.10 rarely missed anything... I'm sure with some tweaking though, it will eventually get back to where 0.5.10 was/is

Odd that, 5.10 was pretty bad for me, 6.0 is working really well. Must depend on your capture card and how you have it set up or something. Mine is all defualt.

I tried it with the default capture settings for my PVR-500 and detection was still very bad. I ran it on Close To Home which had very long black scenes between the show and commercials (at least 2-3 seconds) and it couldn't even detect those. For 1 hr shows it detects at best 2-3 commericial breaks and when viewing the show in schoolhouse the commericial breaks it did detect showed up as 1 long commericial instead of several shorter commercials. For some reason it just can't detect the scene changes.

With 0.5.10 it catches well over 98% of the commericials and when viewing them in school house it detects almost every individual commercial during the break.

I think I'll just stop upgrading because the older version works so well for me.

I'd love to see a FAQ that addresses possible causes and resolutions for those of us with detection issues. I'm guessing it may be due to signal strength or perhaps contrast/brightness etc.. Some people, running the same hardware of the same show get great results.. others don't.. which would imply that perhaps the capture devices record the shows differently...

Does level of encoding play any part? Would something encoded at 1 GB an hour do as well as something encoded at 5 GB an hour? That too could be something that would make mine do poorly and somebody elses do well? Maybe??

[Wheemer]

yeah new version is a no go for me too. Even with the older version my success rate was probably somewhere around 75%. Now it's closer to 25%.

Not sure if this is the proper place to ask, if not let me know

I have just started using SA in combo with dirmon and Nielm's plugin. I am in the Netherlands, so perhaps someone else already knows, but is there a way to detect the part right after the commercial......? I'll try to explain further
Most channels have a commercial break, and after that the channel has some trailers of programs to follow or for other days before the real program continues.
In my case SA very nicely detects the 'real' commercial, but it doesn't recognize the info part the channel shows right before continueing the show.
As far as i can see SA works bij detecting the channel logo (perhaps more stuff, that i don't know yet...). With these info parts there is also no logo shown yet, so i don't understand why SA thinks that this is the program.
Anyway, what settings (if they exist) can change this behaviour?

Cheers,

I agree with the detection taking a step backward on this version. Mine is around 25% as well and I am going to rollback. The new feature to "Never detect last ___ seconds as commercial" is a needed feature but the drop in detection takes priority. I have no doubt Jere will get this fixed shortly though so I will wait till next release and update again.

0.6.1 16 January 2006
- Fixed misidentification of the "Always/Never mark last" property.
- Edge Profiles are ignored if they match 100% of the recording.
- Corrected various causes of crashes.
- Fixed "divide by 10" error in chapters.xml output. (Thanks robogeek!)
- Added "Depth of Analysis" to SAConfig. This is to help with over/under segmenting.

And you can always uncheck it if you want.

Jere

Has anybody in the SageTV comskip world looked into modifying it to use .edl files yet?

I'm still getting leftover SA icons in my system tray. Any ideas to what could be causing them?

[blade]

When I try to change the depth of analysis it always reverts back to the default setting. Also Schoolhouse won't let me apply changes to the settings, I have to reprocess the entire show to see how the changes effect the detection.

That would indicate that SA is crashing. Can you isolate a file that does that?

Jere

[MrApollinax]

I'll have to look when i get home but I'm pretty sure they are all recordings of the show "24" on A&E.

How embarassing. The value is getting saved in the ini file so it is being used correctly, but SAConfig doesn't load it correctly so it looks like it has been saved. In the process, it corrupts the value of "Aggressive Segmentation". I'll post a fix shortly.

Kinda defeats the point of the schoolhouse, doesn't it. I'll get that fixed as well.
