Multiple deinterlacing profiles

[sub]

You could probably roll your own solution using the ".exe channel changer" in your capture source. This way your could run whatever batch files you want per-capture source or even per-channel.

Holy crap, I didn't expect this. I had resigned this thread to wishful thinking.

Pastro, your suggestion is something I will definitely try and post the results.

Sub, is your suggestion something that someone with minimal programming skills like me can do? Is there some example out there similar to this I can use to get the hang of it?

It doesnt require any programming, but if you were going to try replacing registry settings, then you'd need to be able write batch files, and need know what registry settings you were intending to change.

Not that I can think of.

I can do the batch files, and I'm comfortable with messing with the registry.

So in the ".exe channel changer" configuration, I choose an executable, I'm guessing "cmd.exe" and enter the parameters to run a batch file that merges registry setting for deinterlacing on or off. But what executable do I call to then change the channel? I was using "No Channel Changer Required" before so I don't know how to manually change the channel.

You dont need to do anything extra other than your registry work. The channel should still be changed internally within GB-PVR. It would only have been hassle if you'd have the channel changer set to someth other than 'no channel changer'.

Sweet...
I'll experiment later tonight and post the results. I'm afraid I have to break for dinner. Women get grumpy when you don't set the table on time.

Thanks Sub.
and pastro!

If you're using ffdshow as a decoder or postprocessor you can use the "Preset autoload conditions" under the "Image settings" section to automaticly load a "Preset" you define. There is enough flexibility with various match criteria such as dimensions, decoder, DS filter, aspect ratio, and framerates you can easily accomplish this based on content.

I think sub's is more elegant (pisses me off too :-) ) since it would use the same technique to use a batch file called by cmd.exe but would do it automatically instead of with a custom button.
Just create a couple of batch files to write the registry and call the correct one with each tuner's channel changer. Nice..

Well pastro, sub was right. It works using the ".exe channel changer" method. I can clearly see that my liveTV analog channels are deinterlaced, and my liveTV digital channels are still interlaced.

I made two .reg files, one for deinterlace-on and deinterlace-off, used cmd.exe as the executable, and used these as the parameters:

Code:

/c "regedit /s deinterlace_on.reg"

and

Code:

/c "regedit /s deinterlace_off.reg"

I had to put the reg files in c:\windows\system32 for it to work this way. I'm going to tweak it so I can put the path in the parameters.

You can even see it called out in my log file.

Thanks you guys!
