ehh wait 1920x792
though mod8 should be no problem, not 2.40:1 so someone wanted to save every pixel here i guess

Update Newest driver doesn't solve this. I'll report this clip.

Well it's a very old encode (edit: 5 years), so it's not a big deal. IIRC CoreAVC also had this problem with some x264 encodes back then.
I could just re-encode it to fix the problem, but thought I'd see if it could also be fixed on the decoder side. Last edited by ajp_anton; 22nd April 2012 at 22:16. |

Broken clips such as this one will help produce a better HW decoder/driver. Keep 'em coming. Thanks.

Eric,
is it possible to give us a direct QS1(sandy) vs QS2(ivy) comparison on H.264 dxva benchmarks of my collection ? I think both native DXVA and MSDK modes would be useful (maybe together with DXVA-CP) What about 4K H.264 decoding playback utilization of GPU and some benchmark performance ? Can Ivy decode complex 4K H.264 clips of today like the Crowd Run- 3840x2160@50fpsRef4-275Mbps ? Some figures would be useful. If you have a clue - that you can share in public - about HDMI limitation of motherboards, it would be very welcomed to share it with us. Is the lack of 4K output something that will be fixed in the future by M/B manufacturers, or we must forget about 4K output in current generation of Ivy processors ? I was thinking of upgrading to Ivy platform but I think I'll wait for: 1) Drivers to include OpenCL functionality (and check out the performance) 2) Motherboards to include Thunderbolt 3) Motherboards to include 4K HDMI output ? (or DisplayPort ?) 4) Prices to drop ?

HDMI 1.4 supports up to 4K (4096x2160) but only at 24fps. Unless you have money to burn, you should wait for two things to happen: 1) Screens become mainstream ($$$). 2) Real content (movies/tv) becomes available. IVB will be old by then I was thinking of upgrading to Ivy platform but I think I'll wait for: Quote:

More and more products are launching that use Thunderbolt but their price might be high. Quote:

A good sample is this also:
http://xhmikosr.1f0.de/samples/2160p...x264.CRF24.mkv If someone can try to play it in DXVA mode with Ivy and report GPU utilization during normal playback. Also it would be useful to benchmark Ivy with that 4K sample. Quote:
I don't really care - right now - for 4K output. Quote:
My final decision of buying Ivy will be 4K decoding performance and Thunderbolt. I would like to see OpenCL performance too. I think I have to wait for a few months for Thunderbolt and OpenCL and I hope normal H.264 and 4K H.264 benchmark results to come sooner than the first two. @Jakmal Maybe Jakmal could help with benchmark results of 4K H.264 decoding and direct comparison of QS1 (Sandy) and QS2 (Ivy) on 1080p H.264 clips. I have a nice collection of 4K clips I could share for benchmark reasons.

Just to clear things up:
IvyBridge can decode 4K H264 video in HW easily. IvyBridge has nothing to do with Thunderbolt (it's a separate chip). Thunderbolt existence is up to the board manufacturer.

Media SDK sample DS filters
Some users wanted the compiled Media SDK Direct show filter. Here they are.

Do you mean the player's process CPU utilization not the entire system? Which clip did you use (bitrate, codec, resolution)? RAM type? OS? 32 bit?

There is only a resolution limit for DXVA2 Native (not even CB), because auto-detection of 4K support is not working yet. I also did a (very quick) test with QuickSync and 4K decoding, and it does not activate itself for me. Might be a driver thing, i dunno. Need sleep, more testing when i have time.
