Thanks, I have also registered cyberlink codecs and they work fine with h264 and HW acceleration DXVA. Been running DVBviewer for a week or so now and it works fine with DXVA enabled for h264 using Cyberlink codecs.

What we really need is someone with an NVidia or Intel Graphics to play the same vids using LAV with DXVA turned on and report back.
Looking back at the LAV fixes over the last couple of years these issues are mentioned many times. These issues are probably ignored by many software houses as the bog standard h264 works without dxva, on many apps the DXVA is turned on as default and cannot be turned off and I believe that is what is causing the corruption. However this issue is affecting many users and needs fixing.
These two video I am sharing play fine for me using WMP
They screw up when played using DVBviewer and MPC-HCx64
In MPC-HCx64 the videos also fail when LAV filter is disabled. Disabled the codec does not appear to do anything but if you change the filter DXVA settings then that does make a difference.
The unknown factor is what CODEC settings does WMP use and how to change them.
Just added those videos to my DLNA streamer running from my PC and I can confirm they play perfectly on my SAMSUNG UE55KS9000, which is what is expected. The TV will have its own GPU so this seems to indicate there is no problem with the videos themselves.
yes as I mentioned before progressive scan videos work most of the time.....
I have loads of videos taken by iphones (1080p) and all play fine with LAV DXVA turned on.
AMD try this video which works with LAV h.264 ....1080p
Hi, Engineering have analysed the ciip you provided and comeback saying "the corruption you see is because the clip itself is already corrupted, the first frame is a B-frame and it does not contain and SPS/PPS." This of course is beyond my pay grade, but I found something odd. No matter what settings I use in MPCHC, the video is corrupted. If I play the same clip in VLC is plays fine. I've gone back responding that you also experience the corruption while watching the live TV broadcast. Is this correct ?
Hi Ray, thanks for your response. I can confirm that when I enable LAV filter DXVA2 with H264 hw acc, the picture is corrupt when I watch it live, same applies when I use Microsoft decoder. This issue of no SPS/PPS in the media type was supposedly fixed by LAV support team in version 0.66.0 Also in my case that video I sent you plays fine in MPCHC and DVBviewer when I disable h264 in LAV filter. LAV Filters 0.68.0 out - General DVBViewer Pro/GE...
Just spent about half an hour changing channels (all H.264 1080i) and noticed a variety of results. The data stream can vary from approx 3MBit/s to 10MBit/s ....most of the channels with very low bit rate the picture is very bad, the HD channels with higher bit rates fare a lot better and in some cases are ready for a minute or so before you notice a failure. This obviously throws a different perspective of the problem. The channels I was looking at in the UK ....BBC1 HD, ITV1 HD Channel 4 on Freeview, also tested on Freesat ....one channel NHK World HD the picture is totally frozen ( the sound is OK).
01-09_22-57-32_NHK World HD_NHK Newsline.ts - Goo... The above video just recorded from NHK World HD the picture totally freezes when played live or recorded using H264 HW acc DXVA, when turned off it plays fine. This was taken off fresat (DVB-S2) so is different transmission type just in case it was DVB-T2 that was causing the issue. btw Ray, when I play the first video I sent you on Friday in MPCHC with h.264 turned off in LAV it plays fine for me. Don't forget that if you use another decoder it may have H.264 HW acc turned on as default so may be initiating DXVA HW acceleration.
