HD 1080p Playback

[guyzk1]

Hi

My computer configuration is as follows
CPU: E8400
MB: ASUS P5K Pro
RAM: OCZ 2x2GB 4-4-4-12 (Dual Channel Mode)
GC: Galaxy 8800GT 512GDDR3 + HDMI

When playing HD 720p movies everything is fine.
When trying to playback divx or xvid HD 1080p movies or movies from my HD JVC camera (recording at 1080p) the picture is jittering!
What kind of hardware do you need to playback this type of quality without any problems.
Isn't my hardware supposed to be enough, I just bought the machine a few days ago!

Please help me.

Tell us what your display is. I assume you have a 1080p-capable HDTV?

You might simply have a driver issue with the NVidia card, though I can't help there.

 

[guyzk1]

I have a Samsung Full HDTV 1080p display and I am using a HDMI cable.

I just need to know if my computer configuration is enough to playback these kind of movies. and if it is what could be the problem for me.

Thanks

i'm assuming you have all the proper updates, mobo/vid drivers installed? i play 1080P content on my HTPC with an x2 5600 with onboard video with no jittering or skipping.

Your hardware should handle any kind of 1080p with ease, if under proper acceleration. What application do you use to view HD and what's the CPU usage like when you play 720p, 1080p? Sounds like there is no hardware acceleration.

 

[TheOtherRizzo]

It's not about resolution, it's about codec and bitrate. You have to make sure you use the right software for the right video.


short overview

AVC/h264: best software decoder is CoreAVC, best hardware decoder is Cyberlink (only newest generation cards support this, and many pirated videos don't).

VC-1: no good software decoder available, best hardware decoder microsoft (works on most setups except ATI/WinXP combo).

MPEG-2: best software decoder dscaler5, best hardware decoder cyberlink (works on any card).

Everything else: best software decoder ffdshow, hardware decoder not available.

And another thing most people don't realize is that it's not 1080p that's hardest to display, it's 1080i. 1080p is only decoding, 1080i is decoding + deinterlacing.

Installing the Purevideo drivers helped a lot for me, you can buy them from the Nvidia website. AFAIK, Zoomplayer and PowerDVD also support the Purevideo drivers and integrate them. I am personally a large fan of Zoomplayer, but then again PowerDVD has run HD-DVD 1080p content flawlessly for me and distributed the load pretty good across both CPU cores as well.

hey i see people saying ati is better for HD playback, why is this?

 

[TheOtherRizzo]

There's no such thing as purevideo drivers. What you are talking about is the nvidia mpeg-2 decoder. It's not bad but the cyberlink on is better for TV streams. And it won't help for VC-1 or AVC.

One reason people say ATI is better is because nvidia doesn't support full VC-1 decode (only part acceleration) which isn't really a problem though, as opposed to ATI who don't do any VC-1 acceleration at all in WinXP (only in Vista), which is a problem.

Guyzk1, first the good news: there is absolutely nothing wrong with your system; the display is great; the machine has plenty of power to do the job

Unfortunately, as noted above, NVidia forces you to pay for additional PureVideo HD driver software. I REALLY think this is a scummy practice, because ATI does it right out of the box and doesn't charge extra. It's a big reason why I opted for ATI for my newest build.

I'm not a big fan of NVidia as a company. They try to soak their users at every opportunity.

:thumbsdown: :thumbsdown: :thumbsdown: :frown:

But purchase, download the PureVideo software and install it, and I think your problems will go away. Too bad you have to deal with NVidia's racketeering operation.

No. Nvidia's PureVideo software is not only not required but also undesirable. It's old garbage, to be flippant.

Decoder software is required to make use of DirectX Video Acceleration, particularly for advanced formats namely AVC and VC-1. Such is available free of charge from projects such as ffmpeg which is incorporated into MPC-HC (highly recommended), and eventually ffdshow and VLC if not already. Otherwise, it may be purchased from the likes of CyberLink.

False. VC-1 is indeed accelerated with XP. I cannot even guess where such misinformation originated.

I stand corrected. I am ashamed. :brokenheart:

I have to admit, NVidia should really include all the decoding software you need. I think you're right about that stupid PureVideo stuff; I installed it on my Athlon X2 system and it basically failed to work at all. It wasn't compatible with any of my movie players and I wound up having to uninstall it just to view standard-def DVDs. I don't remember the details, it was awhile back.

Unfortunately, our OP still has this terrible problem. His computer is plenty powerful enough to do 1080p in its sleep. I hope your info will help him.

So, original poster, I apologize if I led you astray.

theres no good VC1 software decoders?

 

[Auric]

A couple things worth noting aboot VC-1 are that CyberLink's decoder is not functional outside of their own player (unlike their excellent AVC and MPEG-2 decoders) and that Microsoft's decoder is not capable of DXVA in XP, at least, despite being enabled by WMV Power Toy and no matter the output renderer (Overlay, VMR7 Windowed, VMR9 Renderless, or EVR). So, that's why aforementioned ffmpeg VC-1 is such a boon. Also, a stand-alone filter is available so MPC-HC is not strictly required -particularly, for instance, if some media center type software is preferred.

microsoft: terrible performance without dxva, despite multithreading, problem for many ATI cards
libavcodec: single core only, no interlaced support
cyberlink: doesn't work outside of PDVD
arcsoft: only connects to its own splitter, no deinterlacing


auric: maybe there are some ATI cards that do vc-1 dxva in XP but I can't tell because they lie about the card that I use on their own website (x1950 pro). And why do you say ms decoder doesn't do dxva?

 

[kkk60091]

powerdvd's vc-1 decoder has been cracked since last year. you can already use it outside powerdvd... don't ask me where to find it.


vc-1 full acceleration only works on ati hd2400,2600 &hd3xxx series & those new nv 8400gs

Now that's something I would be interested in! Any hints?

With any splitter though or only Sonic's which introduces other limitations?

Well, the first generation hardware decoding from both ATI and Nvidia had limitations. Like kkk60091 says, a current model is required for full decode anyway so there's little point to messing around with old gear for partial decode at best.

 

[UpstartXT]

If I didn't understand anything but "HDMI" and "HDTV" said in this thread, is there some sort of guide or resource I can go check out to figure out WTH is being discussed?

 

[kkk60091]

back to early dec'07, my friend told me that some chinese people cracked the clvc1dec.ax file when i bought him a 2600xt. just like the h264 decoder, we loaded it up through kmp. it works fine.

he showed me the info from a hardspell.com website page. it was chinese. don't ask me. i don't remember. it was just a zip file with that clvc1dec.ax in side.

i heard the purecodec pack has that cracked file since last dec. so you may be able to extract the file from there.

personally, i don't even use that thing. on a quad, it's meaningless.

 

[Dadofamunky]

Just took a look at ffmpeg; they certainly don't make it terribly intuitive to integrate it into your system.

I'll be investing in a 24-inch or 26-inch monitor Real Soon Now to get 1080p out of my Vista system. Sure hope my existing player still works. I don't care if I'm stuck with CyberLink as my player.

Too bad Microsoft still doesn't understand hidef support. Ballmer is the worst CEO in the US, for many reasons that are too numerous to mention here..

I am not aware of a guide but as for resources, doom9 forums should bring you up to speed.

Linky and direct linky. The advantages of a purposely designed video processor (versus general purpose CPU) are superior quality and efficiency (which at the least translates into lower power useage, if not better performance against a quad core).

As said, it is already integrated into MPC-HC and available seperately:
release version (MPCVideoDec.ax) or test version. PowerDVD is not a bad player as commercial offerings go and its decoders and filters are top notch but MPC-HC as a universal DirectShow player is more powerful yet sports an ergonomic interface. It is a pity that CyberLink has cranked up the restrictions on its filters with the latest version

Well, I think its a bit more complicated then that. I'm sure there's licensing fees and such that MS doesn't want to pay to integrate HD playback, especially since HD-DVD was powered by their software and Blu-Ray is powered by Java. Once MS rolls out their digitally downloaded content I'm sure you'll see HD playback supported, suddenly. I'm not holding my breath though considering how long it took them to integrate a software DVD player into WMP and MC. But ya I'm pleased with PowerDVD Ultra, even though they're constantly stripping its non-disc format HD playback capabilities.

I agree that there is no point at all of partial decode for AVC but for VC-1 this isn't the case. Without partial dxva the microsoft decoder can't play HD DVD VC-1 smoothly even on a 2.8 GHz AMD X2. Cyberlink can but it won't work outside of PDVD (I tried the linked version but it didn't change anything).
