purevideo question

[SpeedEng66]

ok bear with me I only dab around so im no expert (im just a wannabe 🙁 )
sorry I dont know what purevideo is all about
I read alot of article how it reduces the cpu usage, how it enables h264
but does it help me out tho?

so my Q's is
do I need purevideo if im using a regular pc dvd player?
or can I use something else that will enable the hardware?


Thanks for everyones time

It depends both on what video card you have & on the software program you are using to play the DVD's.

opps my bad

I have a older card
bfg gf 6200oc (256mb 64bit ewww🙁)

I using windows media player

I would buy one of those windvd/nero software packages if it would make a difference,

here's my spec (if it matters?)
aopen i855gm (s479)
pent M 1700

Nvidia's PV decoder packs are not required (video component only for MPEG-2 anyway). But some commercial DxVA decoder is to enable the "PV" functions of the hardware to offload from the CPU for MPEG-2 (DVD & HDTV), AVC (BD/HD-DVD/HDTV) and VC-1 (BD/HD-DVD)

Whether they will make a significant difference depends upon the source material (codec, resolution, bitrate) and the degree of multi-tasking capability desired.

Best thing to do is grab a demo decoder/player (PDVD/WinDVD/Nero) and try it out with samples of what you expect to play. The PDVD decoders are the best but simply for DVD not really worth buying a full retail type package. The OEM version included with many DVD drives or available seperately for a few bucks will do. Upgrades to the AVC/VC-1/BD/HD-DVD versions are then possible at less cost but would depend upon whether playback of such material is desired or even possible given those hardware specs. An unmentioned requirement for DxVA AVC (and presumably VC-1) is SSE2 but you should be good there.

If CPU utilization is not a concern then you could just stick to free decoders such as libavcodec and libmpeg2 included with ffdshow, MPC, VLC &c.

Here's an overview of PureVideo.

Purevideo

Not really required unless you really want the hardware acceleration.
Just keep in mind that if you use ffdshow with purevideo your not gonna get hardware acceleration.
