dscaler 5.0.0.4 codec

[m0ng00se30]

No you can use DScaler5, just like nvdvd, or sonic decoders. This is a software decoder, the 3rd party page is referring to a hardware solution I believe.

FFDSHOW is of great value... its does a lot more than Dscaler's MPEG2 decoder... If you have the horsepower I think FFDSHOW is the way to go because you have total control over everything. If you like to tinker till its just right.. then I would say ffdshow... I've tinkered with it and gotten a decent picture, but my lack of knowledge about all the settings limits my setup, so far out of the box for my setup dscaler5 has been the best so far...

But one persons good setup is another mans junk... milage may vary... try them all if you can. Can't hurt...

I have to agree with m0ng00se30. I really like Dscaler. Out of choice I would use the NV4 decoder (as I have a 6800GT) but I just can's get it to work without dropping frames every few seconds. I was really amazed at Dscaler5 as I had tried it when it was at vsn 4.xx and it wasn't that good. The fact that it is free is superb. I would put it as the second best decoder that I have seen (NV 1st). winDVD6 is actually a pretty close 3rd.

As far as ffdshow goes, I had a short fling with it but I didn't really see any major benefits. I only run sage on a 32" CRT at the moment, so the quality looks fine so far. I am going to be upgrading to some sort of flat panel 40"ish screen at some point soon and I am slightly worried about how the whole thing will look on that. I have a feeling that I will have to get involved with ffdshow again!!

To expand, what the 3rd party page is referring to is that Elecard is required to use the built-in Dscaler deinterlacing filter that comes with Sage.

FFDSHOW is of great value... its does a lot more than Dscaler's MPEG2 decoder...

However (and this seems to at least get overlooked a lot) ffdshow is NOT a decoder, it still requires a decoder like Dscaler 5 to work, what it does is process the raw, uncompressed output of a filter like Dscaler 5.

Dscaler 5 + ffdshow has great potential. Firstly, Dscaler 5 has only very basic (weave or bob) deinterlacing built in, however if you were to combine Dscaler 5 with ffdshow and MoComp2 or TomsMoComp deinterlacing you'd have a nice combo.

For my part, nVidia 4.0 is offers great PQ, and is just easier, I don't need to mess with ffdshow or anything, I just have it set up in DXVA mode and my 6800 takes care of the film detection and if necessary Pixel Adaptive deinterlacing.

alsp dscaler 5 especially with ffdshow is going to use more CPU usage than nvidia decoders with DXVA enabled either for the regular decoder or the VPP

[Wheemer]

Is the Dscaler 5 decoder hardware assisted decoding? or dvxa decoding, whatever you want to call it...

[kny3twalker]

no
it does not use DXVA at all
so CPU usage will be a little higher

[stanger89]

Of course I can play a 1080i transport stream with Dscaler 5 on my AXP 1800 so that's pretty good IMO.

5.0.0.5 is out:
http://prdownloads.sourceforge.net/d...e_mirror=voxel

[edbmdave]

ok, Anyone looked at the new PowerDVD 6.x? I saw on some on the MCE pages it was out and given goods reviews on low CPU and good PQ.

Is there anyway to confirm they (PowerDVD 6) support VMR9? Also it looks like ATI has just updated it ATI DVD Decoder, thought I would give it a try too, anyone know anything about it?

I tried it and compared to the Sonic, I had less stutter/tearing in my video. I will let it run for a while. I did install DScaler 5.0.0.5 and it also had better PQ (to my eyes) than the sonic decoders, I will see if can see a difference with PowerDVD.

I have installed Dscaler and changed in the properties file the additional video filter line.
I can now select and use the Dsaler decoder in Sage but cannot enable the Dsaler Deinterlacing filter in Detailed setup.
What do I need to enable that, please?

[m0ng00se30]

If I'm not mistaken... that setting doesn't apply to using DScaler5. Thats only use for a specific hardware card using the filter can came with SageTv.

[gplasky]

No-you need to use the Elecard (Moonlight) Decoder to take adavantage of the Dscaler Deinterlacing Directshow filter. Once you install the Elecard decoder you will be able to go into that setting and configure different DScaler filters. This really has nothing to do with the Dscaler Decoder 5.0.0.5.

Plus there's not really a point since you can do the same thing with ffdshow.

[jan smit]

Thank you both

This should work with 2.0.20 right? I installed DScaler 5.0.0.5, changed the sage.properties line to:

videoframe/additional_video_filters=DScaler Mpeg2 Video Decoder

Shut down and restarted Sage, and it still does not appear in the decoder list in Sage.

[Wheemer]

Just a guess, I thought the video in out stuff was needed until recently, so give this a try:

videoframe/additional_video_filters=DScaler Mpeg2 Video Decoder,Video In,Video Out

[GbrNole]

if you're using sage service you have to add that property to both sage.properties and sageclient.properties

Thanks that worked! I should have seen that little note at the beginning of this thread, but lost track since everyone seems be using 2.1+.

DScaler definitely takes up more CPU. About 20% more on my Athlon XP 1600+, therefore I get stuttering. Looks like the nVidia decoders still work best for me.

How do you go about configuring ffdshow to use Dscaler5 as the decoder??

I looked in the settings and I can't seem to figure out how to do it. Purevideo drops framed and has the picture flicker. Dscaler5 is better overall for me... but leaves just a bit too many deinterlacing artifacts for my taste, so I would like to get the best of both worlds if possible.

Are you using smart or automatic? Smart doesn't always work properly and will drop frames and cause some artifacts.
