Intelligent Frame Correction - PlugIn (9 Viewers)

[Marvman]

I'll try using a non-DXVA codec to see if it makes a difference. VMR9 doesn't work properly for MP on my Vista system, so that might be difficult to test.

One thought to work around the high CPU spikes - could you implement another hotkey (like the 'manual control' key) to trigger a 'one-shot' black-bar detection. Or maybe it could toggle the auto detect on/off ?

Tony

toggle auto detect on/off would be the easiest way, I'll think about it

The spikes are absolutely strange, you already use a DXVA codec and still have those spikes?!?!?!?

I saw you had 56 open process' in your task manager, when I'm running firefox for example my cpu jumps +20% up, and I'm notice stuttering too. Try to disable all non needed services and process' if you didn't already. Otherwise I have no clue. As I already said, your pc specs are better than mine.

It's a dedicated HTPC so I already have some services disabled, and normally nothing much else is running other than MP.

The spikes happen at the 'scan interval' rate when black-bar detection is enabled, so it's definitely related to the frame grabbing. I think the other person complaining about high CPU usage (Nephilim, near the start of the thread) was also running Vista.

Hope in Windows 7 this doesn't happen, want to change some day. Or could that be a EVR thing? EVR doesn't work here (get a gray screen)?

Hi Marvin

I am using IFC on my "productive" system now. Especially the zooming effect is a highlight

There is only one thing that is a kind of disturbing. The left bar detection is too "nervous". That means in a normal 16:9 transmission you often have pictures with black bars at the left (e.g. a picture is shown in the news, advertisment). So if possible I would vote for a dedicated flag to deactivate left bar detection.

Regards

Oliver

I have same problem. Pls make an option for disable the left bar detection.

thx

I'm voting for that flag too , it will be in the next version.

Tip: when you move the rectangle of Black Area L/R to the middle (you can make it smaller too), then it shouldn't detect black

For Wouter:

the attached config that should work for him.View attachment IFCwouter.xml

For all other I attached my config to the first posting. Import (if you want) and press "save and close".

Yes, 480p/576p is not HD - whatever Apple might think

Yes, correct. I wonder why the frame grabbing causes such big spikes (with Vista+EVR+DXVA+nVidia at least) ?

Tony

Maybe you can play a lil bit with VMR9 and EVR and codecs, maybe you notice a difference.

I'll try using a non-DXVA codec to see if it makes a difference. VMR9 doesn't work properly for MP on my Vista system, so that might be difficult to test.

Tony

I've done some testing - I still get the CPU spikes using VMR and non-DXVA codecs, so it looks like it's maybe a Vista thing.

Anyone else using IFC on Vista or Win 7 and could check for CPU usage with black-bar detection enabled ?

Actually, i think this is causing some hangs for me. Using Windows XP, VMR9. I get this thing repeating in my error.log - seems to happen whenever I want to stop TV, or possibly changing channels. Any ideas?

At some point I'm going to try this on Windows 7 to see if it's an XP/VMR9 thing.

Thanks.

Hi bazz,

try the latest DirectX version and driver, that exception comes from MP. Had a similiar problem while coding that plug-in, and i had to need to update my drivers.
