Can I increase the CPU priority of the IR software?

[judoGTI]

I use a combination of nVidia decoder, DScaler interlacer and ffdshow and this gives me about a 90% load when watching TV or recordings.

Because of this my remote response time is really sluggish. Sometimes when I try to manually key in a 3 digit channel, Sage only gets 2 of the three digits. Or if I press volume up it takes 5-7 seconds to have the command be executed.

Can I increase the 'priority' of the IR software have have it perform better? Does this make sense what I am asking?

You don't mention the name of the software that you're using to process infrared signals, so I'll assume that it's SageTV. If that's the case, then I think the answer is no.

But, you could switch to Girder and increase that application's process priority, which *might* help you with this problem.

What about the '/abovenormal' switch when starting sage?
Your real problem, I believe, is your processor. I think this is a sign to upgrade

If his goal is to make the IR features of Sage have priority over the decoding and rendering features of Sage (and that's what I thought the goal was), then increasing the priority of the Sage process isn't really going to accomplish that.

Okay. Good point.
But if all that other stuff is muscling out sage ... ?
Thanks for the learning, salsbst

[salsbst]

All that other stuff is happening inside Sage's process as well. In most cases, DLLs (Directshow filters like Dscaler and MPEG2 decoders are DLLs, they just have different file extensions) run inside the process of their client (SageTV). Thus, the relative priority is not controllable from outside the application.

Sorry, Im using the Hauppaugge new 45-button remote and the IR & Blaster software that comes with it.
(I obviously told Sage to use this software in the setup)

If his goal is to make the IR features of Sage have priority over the decoding and rendering features of Sage (and that's what I thought the goal was), then increasing the priority of the Sage process isn't really going to accomplish that.

This is what I was trying to do. I was thinking that since the remote/IR is used so infrequently that boosting its priority would give me the response I was looking for and still keep the decoding and rendering working strong.

It probably is just not having enough CPU umph, (AMD64 2800+ @ 2.4Ghz) but I dont want to keep dropping more and more money into this money pit! lol.

I suppose you could try increasing the priority of ir.exe -- the Hauppauge remote code is not run from within SageTV.

One other thing to look into, however, is what someone here found out a long time ago: If you happen to have Norton AntiVirus (or possibly others), make sure that you exclude the SageTV recording dirs from its autoprotection.

That I didn't know. Learning has ocurred!

That I didn't know. I think this holds promise.

Yeah -- the Hauppauge remote program is like Girder, in the sense that it is separate from any application it controls. I just figured you were referring to SageTV interacting directly with a USB-UIRT or some such thing.

Cool, Ill give it a shot this weekend. I believe this needs to be done everytime the program is loaded or each reboot.

"
To do this: Load the program you wish to change the priority for and press CTRL+ALT+DEL to bring up the Task Manager. Select the applications tab and highlight your program. Right click the program and select 'go to process.' Now right click on the highlighted process and choose 'set priority.'

The higher you set the priority above normal, the more CPU time the program will steal from other applications when you are multitasking.

Well I tried it and it didnt change too much. It seems you need to have CPU usage under 50% to have instant IR response in Sage. I tried turning all my filters off and had my CPU load around 60% and still had the channel guide scroll lag. Ah well.
