LAV video decoder question.

[wcwman18]

How can I activate hardware decoder? I have a ADM Radeon HD 6450. Which I believe I can use DXVA2 Native. Right now active decoder shows "inactive"

Here is my current avs script

DirectShowSource("imma.ts")
Lanczos4Resize(704,400,6,6,-6,-6)

u can't use native DXVA for anything but playback using specific renderers under specific OSes

So, the best way to use my 6 core AMD system to encode is to use threads for multi-threading 6?

There is no best per forum rule 12. :devil:

Ok, I meant with using the settings in LAV.

Not necessarily.

N threads will fully utilize a system with N processor ocores only if you make the assumption that each threads always is ready to execute and never has to wait for another thread.

In reality this assumption often doesn't hold true. The x264 encoder, for example, needs about 3/2 * N threads to fully utilize a system with N cores...

Is their any taskbar icon that you can see to make sure that LAV is being used?

If I am using your encoder software with this script

DirectShowSource("imma.ts")
Lanczos4Resize(704,400,6,6,-6,-6)

Any settings within lav you can recommend?

You are asking the same things over and over again, but it seems you don't really take the time to understand the answers.

In your other threads it has already been explained how you can build a DirectShow filter graph for DirectShowSource() manually, to be sure that a specific splitter and/or decoder filter is used...
