This could really be a noob question but what good is it to enable HW deinterlacing when using QuickSync Decoder? Deinterlacing is enabled in MadVR (if in doubt) and set to auto in LAV. Based on the discussion here and here, you said MadVr would be more efficient in doing so assuming Madvr is 'completely' GPU oriented.

There are other use-cases than simple playback, where it is useful. Not always is a renderer involved, or there is some processing before the renderer which needs progressive video. Its all about the options.

Well, I just want the videos to play and have better picture quality, atleast that which can be achieved with the GPU handling almost every processing. CPU heat annoys me (I have mobile Platform).

So, I have QS Decoder HW Acceleration enabled in LAV and using MadVr, although 'avcodec' is better compared to Quicksync decoder. Therefore, I am good to go with HW deinterlacing option disabled in LAV and let MadVr handle it ? Because, both will be using GPU to do the same kind of work. But if disabling Deinterlacing in renderer and enabling HW Deinterlacing in LAV gives me something better without performance hit or costing the CPU , I would be glad to enable it. Otherwise this line is good:
"For a pure playback chain with no CPU post processing at all, in theory there should be no benefit letting LAV Video do the hardware deinterlacing instead of the renderer" - madshi

As nev says, LAV can be used in instances where there is no renderer involved (such as using it in conjunction with DirectShowSource in AviSynth). So if one wants hardware-accelerated deinterlacing it's beneficial in such a case.

total noob question...

...but I have to ask.

I understand that in order to use MPC's built-in audio delay feature, I need to enable its Audio Switcher. By doing so, am I missing out on anything in LAV Audio? I prefer the ability to tweak the delay via the keyboard.

I have MPC set up to prefer all three LAV elements in External Filters.

Thanks.

ooo. thanks for the update!

does the last change in the changelog render madflac obsolete...?
also quick question, what's the correct install procedure - uninstall and then reinstall?

thanks =3

Question related ordered chapters, just noticed a difference in behavior with the default tag for subtitles between Haali and LAV splitter.

The main video files have subtitle track 3 as default and the OP/ED which is in separate files for the series has subtitle track 1 as default, Haali switches from subtitle track 1 to subtitle track 3 when done playing the Opening and correctly switches back to track 1 when starting to play the Ending file in the virtual timeline.
LAV splitter stays on track 1 throughout the entire virtual timeline without "honoring" the default track tag in mkv.

Is this intended behavior?

Does the latest Lav 0.57 includes the latest intel QS 0.42 ?

No, it does not. I didn't have time or a Win8 system to test on right now, and i don't include untested updates.

Hello Nev.
I see good working HW deinterlacing with QuickSync in new LAV Decoder. It makes 50 fps from 25i source. Thanks!
But CUVID HW deinterlacing stop working to me. It gives only 25 fps from the same 25i source. Option "50p/60p (Video)" is selected. What I do wrong?

If you want to switch decoder on stream switch, you need to activate the option "Remove Audio Decoder on Audio Stream Switch"

Thanks for the new version, nev. QS deinterlacing seems to be working fine on a quick test.
