My PC is Athlon XP 2000, NVidia GF4 TI 4200 (nv 96.43.13). I've tried both Totem and adobe flash player and results are similar. The video is slow at all on my Athlon XP 2000, NVidia GF4 TI 4200; The slowdown depends almost linearly on image size and the volume of picture changed from frame to frame. If output picture size is 200x200 we get good playback almost everywhere (but even not in case of camera moving or scene changing when picture changes much). In case of 1024x768 (16:9) the playback turn into slideshow (3-5 fps) almost in very static scenes, if the camera moving the image freezes up to 0.5-1 secs. This sitatuations tooks place with all codecs I'm using, the slowdown depends more on actual compress rate rather than codec type, but it is pretty annoying everywhere. From nvidia official site i've found in graphic card chipset specs >> FEATURES >> True-color hardware cursor with alpha ° >> Multi-buffering (double, triple or quad) for smooth animation and video >> playback High-quality HDTV/DVD playback High-definition video processor >> (HDVP) for full-screen, full-frame video playback of HDTV and DVD content >>° Independent hardware color controls for video overlay ° >> Hardware color-space conversion (YUV 4:2:2 and 4:2:0) ° >> Motion compensation ° >> 5-tap horizontal by 3-tap vertical filtering ° >> 8:1 up/down scaling ° >> Per-pixel color keying ° >> Multiple video windows supported for CSC and filtering ° >> DVD sub-picture alpha-blended ° >> Motion adaptive deinterlacing compositing So it's very likely none of this features (especially HDVP processor) is currently supported in my nvidia drivers, very likely the problem needs deeper research. Reproducible: Always Steps to Reproduce: 1. Play video with high resolution 2. 3.
Advertisements are not benchmarks and performance is rarely a real bug - especially if the card in question has been on the market for a few years. Perhaps you're expecting too much of your card ? And even if your problem is valid, it's still more a support question, than a bug. Are those any specific videos (links, in that case) or does it seem affect video playback on general ?
I am going to chage the status to CANTFIX If you think this is an error please reopen the bug with additional information
I've installed mplayer and video performance is excellent. Very likely the problem is in poor optimization of Totem and adobe flash players themselves (possibly the problem was in setting of wrong libraries in intermediate step between player and nvidia driver).

I would like to see some investigation and at least leave a warning to other users with this bug
