vdpau xineliboutput tviikkausta

Postby ppaalto » 22.02.2014 17:39

Kun tuli lisää HD-kanavia ja aikaa virittämiseen, aloin tuunailemaan systeemiäni (mopo AMD-prossu (AMD Sempron 145) ja GT210)
Alustana Arch

Ensin Nvidian performance tappiin:
/usr/bin/nvidia-settings -a '[gpu:0]/GPUPowerMizerMode=1'

CPU:n virransäästö ja samalla väyläkello korkeammalle:
echo 2000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

Jostain netistä sitten poimin seuraavia:

xorg-asetuksia
/etc/X11/xorg.conf.d/20-nvidia.conf


Section "Device"
Identifier "Nvidia Card"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "NoLogo" "true"
Option "TripleBuffer" "True"
# ...
EndSection

Section "Extensions"
Option "Composite" "Disable"
EndSection


config_xineliboutput:

video.output.vdpau_enable_inverse_telecine:0
engine.buffers.audio_num_buffers:500
engine.buffers.video_num_buffers:1000
engine.buffers.video_num_frames:22
media.xvdr.scr_tuning_step:150
media.xvdr.num_buffers_hd:4000


Tämän jälkeen temporal_spatial nykii vain aavistuksen verran. Olisko jotain muuta, jolla kuvaa vois parantaa?

No tein sitten heräteostoksen ja ostin GT630 Keplerin passiivijäähyllä (Asus GT630-SL-1GD3-l 1024Mb). 25W max teho houkutteli... Tosta on aika vähän tietoa HTPC-käytössä. Onko kellään kokemusta?

Joo toi olikin päällä. Onko 630 Kepler vai Fermi? Paperilla aika paljon eroa...

Pahoittelen threadin varastamista, mutta jos tuollaisen 630:n hankkisi, niin onko 2GB muistista jotain olennaista hyötyä verrattuna 1GB:hen?

OT: Nykypäivän vaihtoehtona voisi olla tietenkin uusin Maxwell, joka puolittaa tehonkulutuksen Kepleriin nähden: http://www.kfa2.com/750oc.shtml

GT630 Kepler on asennettu ja kuva on kyllä huomattavasti parempi kuin GT210:lla

Itsekin laitoin 630:n tilaukseen kun tulee kolmen viikon sisään pakollinen huoltokatko vdr:lle muutenkin. Samassa yhteydessä löisi sitten uuden kortin sisään tuon vanhan 220:n tilalle.

Itsellä oli aikaisemmin GT220 ja nyt GT630, mutta en huomannut niiden välillä eroa. Niiden välissä käytössä oli myös ION2, jonka teho ei riittänyt HD-kuvalla temporal spatial-lomituksenpoistoon. Videotykillä katsottuna GT220/GT630 1080i HD-kuva oli ainakin minun silmään hieman parempi kuin ION2:lla.
