720/1080p h.264.mkv playback with P4 3.0ghz possible?

post #1 of 17
Thread Starter 
Been having a nightmare trying to get a Celeron 2.66ghz to play 720p h264 files.

Took all the advice here, coreAVC, MPC, and heali. Still wouldn't play smoothly, cpu was always 100%.

My dad is giving me his P4 3.0ghz w/1gig of ram to try out. With the same program setup should this rig be able to handle 720/1080p h264.mkv files 2-10gigs in size?

I'm not sure what vid card is has yet but could upgrade if needed to something that accelerates h264. I heard the ATI hd 2400 or something would be good.


Thanks

It won't be able to play high bitrate 1080p movies smoothly.

Have the same processor and can play 720p smoothly with CoreAVC/AC3filter, but 1080p is definitely a no-go. 1080p is a slideshow and even getting 720p to play smoothly took a decent amount of codec tweaking.

My athlonXP 2600 @ 2.0 GHZ plays back 720p with 70-95% cpu usage, the image never stutters.

1080P is unwatchable, good thing i have a DXVA videocard for those

I have a Dell XPS Dimension with a P4 3.0 Ghz Processor and 1GB of Ram. I can play any 720P movie fine at around 75 to 100 % cpu usage. 1080P are a definate no go though. I have tried WMV HD 1080 files from Microsoft and iTunes 1080P files and even the Batman Trailer from Nero Digital which is an mp4 1080P File

My video card is ATI Radeon AGP 9800 Pro

Same story here. I have a 2.6Gig P4 overclocked to 3.2 (250x13). 720p is no problem, but 1080p maxes out at 100% and skips frames badly using CoreAVC. x850Pro vid card.

Yeah, and after reading alot of threads I think alot of people are having troubles with 1080P files playing correctly, whether it be a $700 Computer or $5000 dollar computer

I'll chime in with the rest and say 1080p is a no go but 720p is good with codec tweaking. I have a P4 2.4 with a ATI 9600pro that can do 720p with aboud 90% usage (depends on the file bitrate). My Quad core Q6600 with 8800gt plays 1080p with about 35% (again depends on the file bitrate (audio and video)).

My 3.0 GHz P4 HT 1.5GB Ram won't play 1080p movies, will play 720p fine. But my laptop 2.0 Ghz Dual Core with 2GB Ram will play a 1080p movie just fine at 40-80 CPU%.

Sounds good guys, hopefully this will work smoothly. I'll update in a day or so when I get it.

Is this true even with a full offloading video card?

Ok so an update here, That file that I had posted earlier from Nero, I think something is wrong with it. I have tried on my computer, a iMac 1.83Ghz Core Duo, 1.5GB Ram, and the new 24in iMac and a Quad Core mac Pro..."I work at Apple" and none of them played it smoothly. So I went to the Dark Knight official website and the download there 1080P.mov file and it played smoothly on the iMac 1.83Ghz. I then downloaded the file on iMac running Windows XP and it played smoothly in Windows Media....Still though, I cant play on my home computer so

My old htpc was a p4 3ghz; it plays 720 and can't handle any 1080p.

My new (cheap) htpc is an e4500 overclocked a little (2.2@2.6ghz) and it can play all 1080p content using ffdshow.

There is a lot of hype about offloading dxva videocards but I think it's irrelevant when a cheapo $120 cpu can handle anything out there.

I have a P4 3.0 HT, 2048 MB DDR2, ATi HD2600XT PCIe.
I can do 1080p blu-ray/HD/DVD onto my philips tv 1x1 pixel @ 24Hz, no hassle.
My cpu is not doing overtime, GPU does it all...

What software are you using to play it? Thinking you need to use something that supports the acceleration, like PowerDVD, to do this. Thanks.

MPC-HC supports hardware acceleration. but files have to be dxva to support it.

media portal + pdvd (and its h264 codec)
2.5ghz amd x2,
ati 2400

720p is cake, can do it all day long, 1080p every now and then pegs the cpu full and gets a little hitch. The nice thing is that audio never gets out of sync.

I think pdvd is an absolute necessity to do hd. The codec is invaluable, hd video is unplayable if I didnt have it.
