ViewModeSwitcher plugin (Version 0.3) (3 Viewers)

Hi ketjap.

The idea of the boxes is that they are always centered. That means if you set the box width to 30%, there are 35% on the left and 35% on the right of the box that's not analysed. The most broadcasters have their logos in corners of the upper black bar so it is necessary to analyse only the middle part of a black bar.

The startpos is a kind of an offset. Some broadcasters send "garbage" in the first lines of their signal (i.e. teletext). Because of this it is important to define a box to analyse that does not contain this "crap"

The centerbox has the job to make the detection more reliable. Just analyse the top and/or bottom bar is a bit critical, because even programs without letterboxes have from time to time "black content" in the analysed boxes (i.e. during an intro of an movie where the whole screen is black with only some words in the middle).
The letterbox detection is only allowed to change from activate to deactive (or the other way around) if the centerbox is not black and the upper or bottom box is black...

I hope that explains it a bit

Bye
Lars

Hi lkuech,

Thank you for your explanation. It's more clear for me now.

Here in The Netherlands the logo's are not in the black box, so that's a bit different in our countries. Now that I changed it to 70% it works great for me. With some shows there is not really a letterbox in the middle of the screen, not in the 25% area. That area looks black and outside that area there is something from the image so it shouldn't be zoomed. (Don't know how to explain this better). As I said, I changed it to 70% Width and till now it always choose the correct zoom mode.

Again, great plugin! Thank you for your good work.

Please explain..., some help!

I just installed your plugin. THX for your hard work!
I'm using an "old" analog CRT (4:3) with a fireDTV-S2 -Card, Vista 32Bit SP1 at a Radeon 34xx Graphics Card (S-VHS) I tested and found no entries in my logfile like "video AR..."

Please look at the attachment. The logfile is from my second pc. (Using a multiseat installation with whs).
I'm not right, if i just understand all...?

Thank you for your support!

Hi,
at first thanks for this tool.
thats something i searched for a long time.
but i'm a noob, could somebody give me a config for:

res = 1.366 x 768 (Lg42" LCD)
4:3 = real 4:3 without stretching (cut on left and right)
16:9 = 16:9

thanks too all and the developer!

Hi piranhabox,

The resulution you give is probably the res of your monitor and not the res of the stream. If you read the first post a couple of times you can figure it out how it works.

Configuration Help

Hi!

I have just reinstalled my MP and now I'm lost...How shall I set up the viewmodeswitcher with those parameters:

2008-12-07 12:56:32.875000 [Debug][VMRenderer]: PlaneScene: crop T, B : 0, 0

This should be a 16:9 PAL stream (it's ARD), and now a 4:3 stream:

I Do not see any difference!

Thanks for any help!

Hi baldur.

Which codec are you using?

It looks a bit like you are using a codec which is not aware of aspect ratio changes, because even the 4:3 content is detected as 1024:576 which is 16:9

Cu
Lars

 

[baldur]

Thanks for your reply - I used ffdshow when I created these logs. In the meantime I know that this codec cannot be used...I switched to Cyberlink, now the log file seems to be alright but nevertheless always the fallback rule is applied.

Currently I have no access to my MP PC, but I can post the new logs shortly.

 

[Swede]

Great plugin! Not sure if this is a bug, but it works the first time I start a movie and not the second, it might be a bug. Anyway, check the log for the first time I start Heroes. First a fallback, then it finds that 16:9 is correct. The second time it's only a fallback. AND even if it says "Switching to viewmode: Normal" it doesn't.

Only way I found to make it work again with avi files is to reinstall ffdshow and the it only works once again.

TV and recordings works fine

All use ffdshow.

Edit: This is an XP pc. I did the same test on another pc with vista and there it worked. Attached vista log. Same version ffdshow.

Edit again: Got it to work if I unchecked fallback. Fallback didn't always work in Vista either. Without fallback, everything works perfectly for me

Trimmed log (first time OK, second not): Whole log attached.

[cpp2005]

Hi Lars,
sometimes a correct rule is not matched and I found the problem: g_Player.Width and g_Player.Height values are sometimes zero in Worker method of ViewModeSwitcher.cs. To fix it, I changed the line
ProcessRules(ARCalc, g_Player.Width, g_Player.Height);
to
ProcessRules(ARCalc, VMR9Util.g_vmr9.VideoWidth, VMR9Util.g_vmr9.VideoHeight);

that's because g_Player.Width and g_Player.Height are initialized sometime after they are available in VMR9Util so there is a possibility that ViewModeSwitcher will see them before that.

btw: what about this patch?
