Hi, using the new ffdshow DXVA Video Decoder with the newest version of Zoom Player Pro, I get no video picture, just a grey screen. Normally use madVR as my renderer but all I get is grey when using the DXVA Video Decoder. My H264 video file is playing and the video/audio codecs are working as they should be I just don't get a picture. I tried switching to Haali's renderer, VMR9, VMR7 and just the overlay mixer. Still no picture. When I turn off the DXVA H264 codec and fall back to ffmpeg-mt then the picture is fine.
I've tried ffdshow Revisions 3189, 3190 by clisd & 3195 by XhmikosR. No change. I even checked all colorspaces in ffdshow output. No change. XP, SP3 & using nNvidia driver 182.08 with my 8600m GT if this makes a difference. Any thoughts? Cheers... Last edited by andybkma; 11th January 2010 at 09:17. |

Build 3190 ffmpeg-mt works for me, too. I don't get a picture though using the new DXVA codec (see above posting). BTW, betaking, what skin is that for Zoom Player you are using and where can I find? Is mighty nice. Cheers

TrueHD isn't like DTS-HD where you can bitstream the core DTS file. The core on TrueHD files isn't accessible. That's why a separate AC3 sound track (matching the TrueHD language) is always included on the BD disc. |

What are the hardware requirement for DXVA (minimum ATI/NVIDIA/INTEL model required) ?
I have an NVIDIA 7600GT and the DXVA filter wont even connect to the EVR. Also, why is H.264/VC1 disabled (unchecked) by default on the "Hardware Acceleration" tab, Isn't the whole purpose of a separate DXVA filter to ensure that DXVA wont interfere with standard usage of ffdshow? |

Modern video graphics card have the possibility to decode partially or completely a video using DirectX Video Acceleration (DXVA) and reduces CPU usage. MPC - HC has an embedded video decoder using this technology to decode H.264, VC-1 video. Unfortunately this decoder supports for the moment only bitstream mode, which means that only most recent graphic cards are supported. * ATI Radeon™ HD, ATI HD3850/3870/4850/4870/5800, AMD Hybrid CrossFireX™ 780G series for H.264 & VC-1 * nVidia GeForce 8500, 8600, 9600 or better DXVA is quite susceptible, so if you want to use it you have to respect those rules: * Windows XP, Vista and 7 * For Windows XP users, select Overlay Mixer, WMR7(9) or VMR7(9) Renderless * For Vista users, select EVR or EVR Custom * For DXVA and subtitles support select VMR7(9) Renderless or EVR Custom. * Video decoder should be connected directly to the renderer. This means that no intermediate filters such as DirectVobSub or ffdshow can be inserted between decoder and video renderer. * DXVA compliant x264 encoded files. INTEL G4500HD Support DXVA !ONLY For vista and windows7! Last edited by betaking; 11th January 2010 at 12:56. |

- TrueHD decoding : enable TrueHD decoder and uncheck TrueHD bitstream - TrueHD bitstream : enable TrueHD decoder and check TrueHD bitstream - AC3 core : disable TrueHD decoder but AC3 decoder is enabled or AC3 passthrough is enabled (and in that case the AC3 blocks are extracted to be decoded or bitstreamed) Same thing for DTS-HD |

But I have a few questions: 1. What is WMR and how to enable it? 2. Does DXVA work with VMR7 Renderless? Information on MPC-HC homepage is a bit old but is more correct in my opinion: http://mpc-hc.sourceforge.net/DXVASupport.html Quote:

if that is the case then decoding the core only from a tru HD track is broken.
None of my true HD tracks play only the ac3 core but when the truehd decoder is enable track plays fine Quote:

Went back to 32bit ffdshow to try the DXVA function.
Build 3195 works well. No blue tones, no green picture. But on seek there is a slowdown and sometimes artifacts start appearing, picture starts to lag exploding with multicolored squares. Seeking is also faster on the non-DXVA ffdshow. Also the video is a little choppy on start(first few seconds) compared to the non-DXVA ffdshow. Result vary with different videos though.

Stupid question, but what should happend when i will try to play h.264 video if my hardware doesnot support DXVA?
ffdshow DXVA Video Decoder is loaded and report DXVA not used or ffdshow DXVA Video Decoder failed to load and ffdshow Video Decoder is used instead? I am asking becouse ffdshow DXVA Video Decoder failed to connect to VMR9 renderer in graphstudio here on my working machine based on "Intel(R) 82945G Express Chipset Family (i945G0)" I think this iGPU doesnot support NV12 colorpace (FFDshow crash if i will try to play MPEG-2i stream and disable all output and keep NV12) - can be related?
