1080p playback hardware (1 Viewer)

[humpty]

I have an hp dv7 laptop, it is 2.0 ghz dual core, 4gb ram and the ati 4200 hd vid card. I have been having troubles getting the 1080 .mkv top play properly. 720p plays fine using coreavc and mpc-hc, but with cpu around 70%. When I play 1080p with coreavc cpu usage goes to 100% and video starts stuttering. I tried uising the dxva on a number of different 1080p that were 4.1 or 4.0 profile and I have problems with all of them. cpu usage stays under 20% but the video gets alot of glitches with green blocks and funny lines. I was using the cyberlink h264 decoder and tried the mpc decoder but same issues with both.
I was starting to wonder if the card could even do the dxva properly. Is there something else I could try or do I have a setting wrong?

I also have a desktop I built that has a quad core overclocked to 3ghz with 4gb of ram and a geofroce 210 card with cuda.
With this computer I can play 1080p using coreavc and cuda and keep cpu around 5%. Is there a way for me to stream to the laptop which will be hooked to my plasma, using the desktop which can handle these movies no problem? It really bothers me that the comp that can handle these movies like nothing is too far away from either of my tvs and the one I can put near the tv cannot handle. I've kinda given up on the 1080 and resorted to 720 but I would sure love to figure out the full 1080p. Any help or suggestions would be appreciated!!

hello

for you laptop did you upgrade the video drivers from amd website ? did the ati 4200 has his own memory or it s shared ram ?, if it s shared ram, maybe it s to slow

1st update the video driver, it s maybe buging with your driver


but a dualcore 2ghz must play 1080p without dxva (but i don't know if laptop are slower or maybe if it s when it s onborad graphic what slowdown)

my athlon 64 4200+ was able to play 1080p 25fps with 1 core with coreavc gefoce 7600gt (but it was overclocked 2.6ghz) on asus m2n sli deluxe
but sins i move it to an lower cost motherbord with integrated graphique (gf7050) it s harder to play 1080p but olso no overclocked cpu go to 75-80%

so it s hard to say if 2ghz dualcore is ok for 1080p

on my m2n sli deluxe i puted an athlon2 620 x4 (@3.2ghz) it can olso play easly 1080p with 1 core


i don't think you can stream from your dektop to the laptop
because it s still the laptop what read the stream
but you can stream with lossing quality (to 720p for exemple)


but you can buy a wireless hdmi/dvi to hdmi transmiter or someting like that

RC2 has improved playback performance. Could you see if that helps?

 

[humpty]

what is rc2?
oh and it would be cheaperto buy another laptop then buy a wireless hdmi transmitter.

I have to go to work but i will check on the video memory when i get back

ok so I updated my catalyst control center and now the dxva seems to be working fine with 1080p. I have not had any glitches yet. my cpu usage is around 50-70% seems a little high but mpc says its using dxva. My only issue now is the motion does not seem very smooth. it's not stuttering but it just does not look smooth. Im not sure if it is droppping frames or what the problem is. Any ideas?

 

[carlo_0000]

use overlay with mpchc (but not working for sub's and dxva or maybe with directvobsub (not tested) )

overlay is the fastest and olso give's better quality as vrm9 (evr ?)

probably your 4200 share the ram memory and than maybe it s not so fast (they recomand ddr2 800 or dual channel 667)
but mine works with an ion and single channel 667 (sometime litle lag) but on xp

if you use vista or seven, you probably getting better results with xp

you can olso try to overclock 5to10% your ram (increase the volt +0.1V) it you can , and test it with memtest

and testing if it help

ok i check the ram it say its is 2048mb hyper memory which i believe is shared. The Ram is ddr2 not sure which speed or how to find that out. I am using windows 7 so I have been using EVR. and it does not seem to be laggin just not smooth but I may be wrong it coukld be from lag but it does not appear that way. I cant use overlay because it does not allow dxva and I have to use that for 1080p or I will get 100% cpu usage.

 

[carlo_0000]

for the ram speed you can use the litle softwere named cpu-z

ho maybe dxva did not work with 7 and overlay

i don't tested a lot on 7 because i don't like 7 same for vista


but under xp dxva work the best with overlay

 

[humpty]

checked with cpuz and it says I have dual channel ddr2 at 400mhz,
I have also done some more playing around and when using EVR custom I was getting alot of dropped frames, which is most likely why the motion did not look smooth. I have changed to EVR (vista/.net3) and Am now getting no dropped frames and it is working with the dxva and I am only using 15% cpu on a 1080p. So it would seem as tho I have finally figured out the right settings to run these movies.

For anyone else with dxva problems updating the drivers fixed my glitchy playback!

And Thank you so much Carlo this has been bugging me for a few weeks and I think it is finally solved!
