6800series+WMV HD playback with BETA 71.20's discussion.

I have used just about every alpha and beta driver out there with varying results but the one consistancy has been zero help with WMV HD. Most of the dets newer than the 61.77's have caused IQ issues in full screen mode, and stuttering issues with DIVX/XVID, the 70.90 fixed that for me *the 71.20's work perfectly here too. Again though, the consistant factor has been playback of the SIL trailer is identical regardless.

This is where it gets interesting, I have been testing on my dual Opteron@1.725ghz system and when playing the trailer would drop hundreds of frames with both CPUs showing a max of 55% CPU usage, this using just about every driver from 66.71 till now. All my testing on this system is being done with MP10 and nVDVD 2.0.

Well, I just played it with the 71.20's and the CPU usage exceeded 60% at times during playback and I only dropped 34 frames consistantly in the same spots on 3 runs with reboots in between. To add to the strangeness nVDVD 2.0 will play it but while I can hear the audio and watch the playback time progress, there is just a slightly grayer black screen where the video should be.

Please post your results and experiences with these players and the new betas. I am at a loss as to how it could be increasing the balanced CPU load on my boxen and drop so many fewer frames, and why it suddenly does not display the video for this file in nVDVD despite the fact it is obviously playing 😕 I am looking forward to reading speculation by our technically informed members as to what could possibly be going on here if this doesn't turn out to be isolated to just my system.
 
Ok, let me get this straight, with the 71.20s, CPU usage goes up, but you get no picture? What media-player are you using? What playback mode (overlay, VMR7, VMR9, etc.)? Very wierd..
 
Yep....Same story. Even though I'm only getting 65% cpu w/no dropped frames....it doesn't matter, that's only b/c of my cpu. The 6800 still isn't working properly.

The CPU balanced load is higher, but the dropped frames are far less than they were with older drivers using MP10. With nVDVD there is no picture but you can hear it playing and see the time progress. With older drivers the video plays but is uberchoppy with nVDVD 2.0
Media player settings are defaults


EDIT:Just tried high quality mode with MP10 and the CPU usage spiked to 68% and I only drop 20 frames now Screenshot
 
In order for a video to play under Windows, the program must create a DirectShow filter graph, or use the Video for Windows interface. Windows Media Player 10 uses the Video for Windows codec for Windows Media Video (on my PC at least). Other players like Media Player Classic or possibly nVDVD (not sure) may attempt create a DirectShow filter graph and fail on the video part because the DirectShow format codec isn't present. Your problem most likely lies in the fact that nVDVD uses DirectShow filters. Fortunately, a program called graphedit can track and hook on to DirectShow (but not Video for Windows). It really depends on how your media players are configured.

Download the Windows Media codec package (freeware)

Download Graphedit (freeware)

If it doesn't work after the codec package is installed, then try the following:

Next time you load up nVDVD, start graphedt.exe while the file is 'playing', even if it is playing without video. Make sure no other video programs are open. Then, once in graphedit, find the button that says 'connect to a running graph' (third button from the right on the toolbar). Select the only graph in the list that appears and click OK. Then open another player that can play WMV HD, with the exception of Windows Media Player. Try Media Player Classic (a GREAT freeware player that uses DirectShow filters).

Download Media Player Classic (Freeware, Win98/ME)

Download Media Player Classic (Freeware, Win2K/XP)

If you have any questions just reply. I'll be checking out this forum often because I'm concerned about the video processor issue as well.
 
Thanks for taking the time to help xtknight 🙂 I'm somewhat familiar with graphedit and I am not concerned with the failure to suddenly playback in nVDVD. We have been using WM9 since July as the default player for testing the SIL trailer and 10 for a few months now, which is why I use 9&10, just to be consistant in the testing methodology. Others had established sometime back that other players do a better job than Media Player. So you see, I'm not looking for a better player with improved playback, I'm just attempting to understand why this is happening, and only with these drivers.

Why with these particular drivers I see increased CPU utilization and less dropped frames over any other dets is the topic I was hoping others could help investigate. The failure to display the video in nVDVD though it was obviously playing, is also only a issue with these particular drivers. I think I will need users who already have systems that drop frames during playback to test it and see if they too see fewer dropped frames or not. I can't imagine that it is SMP specific though with dual-core coming who know? 😕
