ylee at pobox Nov 20, 2008, 12:58 AM Views: 4830 Permalink Just how great can VDPAU be? Like everyone else, Nvidia's surprise announcement[1] of VDPAU has excited me. I've already begun imagining buying an inexpensive fanless 8-series card and instantly making my frontend capable of playing full-bit h.264 HD-PVR recordings as well as the MPEG-2 recordings it does such a great job with, instead of building a new high-powered Core 2 Duo box. On second thought, though, I'm not sure how realistic this is. My understanding is that VDPAU is basically an updated version of PureVision, Nvidia's longstanding hardware-dependent video decoding-offloader for Windows. I watch AVSForum's HD-PVR forum for Windows users. Intermixed with the numerous messages detailing forum members' ever more-convoluted ways of recording and watching their TV shows--Rube Goldberg-like setups that would make any MythTV user alternately burst out in laughter and shake his head in pity---are many reports of how horsepower-dependent HD-PVR recordings are, even for Core 2 Duo owners using CoreAVC. In other words, despite their having PureVision already, things don't seem to be any better performancewise on that side on the pond. Am I mistaken? What am I missing, if anything? The recently-posted test of VDPAU and mplayer (<URL:http://www.gossamer-threads.com/lists/mythtv/users/357702#357702>) is certainly *very* encouraging regarding both GPU and (more importantly) CPU usage, but a) Jason used a Core 2 Duo box and b) as we all know, mplayer isn't the MythTV internal player. [1] 2008 has certainly been a year of exciting MythTV-related announcements, eh? It opened with the HD-PVR announcement--something we'd all hoped for but, I don't think, anyone expected quite so soon--and now it is closing with this. -- Frontend: P4 3.0GHz, 1.5TB software RAID 5 array Backend: Quad-core Xeon 1.6GHz, 6.6TB sw RAID 6 Video inputs: Four high-definition over FireWire/OTA Accessories: 47" 1080p LCD, 5.1 digital, and MX-600 _______________________________________________ mythtv-users mailing list mythtv-users[at]mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
