Tom,
I've reported the same problem a few posts up.

Twingo · 27th March 2011, 02:11

Just try to help a little bit, I have same problem after using ATI DXVA today. I was using software on my HD5570 card before to decode h264 movies, but today I updated Coreavc to use DXVA for ATI cards, then my MPC-HC is asking me to update my directx after I set it to vmr9-renderless as described on MPC-HC website. It was okay before I updated directX but after I updated my directx to june 2010 release then the same problem (as reported by Barlow) occurred to me, my original directx is from windows xp sp3, never updated before today.

Sample

Edit: forgot to mention, card is a Radeon 4850. OS is Win7 64bit.

Sorry... must have missed it

. In the meantime i tested DSGraphEdit - it crashes too. Only the "good" old Microsoft GraphEdit seems to work though...

Can anyone elaborate on an MKV seeking bug in WMP. Seems in certain systems it does not seek. What we are looking for is your settings (DXVA or CUDA) and content type.

I have exactly the same bug with my laptop using intel X3100 integrated video, I tried various settings but it won't work, dxva on/off, deterlacing on/off, low latency on/off or agressive on/off they all won't let me seek by pulling the progress bar. I was playing Mad Love 720p X264 mkv by Dimension.

We have samples now and can reproduce it. Thank you for the follow-up.

Hi,

after upgrade from CoreAVC 2.0 to 2.5 with MediaPortal 1.1.2 i always get "Unable to play video" error on mkv files, besides everything works in Windows Media Player.

Before the upgrade everything works with CoreAVC 2.0 .

If I switch to another h.264 Codec in MediaPortal configuration as: MPCVideoDEc, FFDSHOW, etc. everything works fine.

I have tried to get more info with GraphStudio but it crashes (as reported a few posts back) with CoreAVC 2.5.

Has anyone experienced such problem?

BetaBoy · 27th March 2011, 15:24

ok... we found the bug for ImediaPosition and ImediaSeeking (WMP not being able to seeking in some MKV's).... gonna take a look at the issue with MediaPortal and Rad's Graph Studio next.

BetaBoy · 27th March 2011, 15:56

- ImediaPosition and ImediaSeeking bug, FIXED.
- Graphstudio bug, FIXED.

Going to see about MediaPortal next but I am assuming its fixed as well as it was the same bug as Graphstudio.

Ruklaw · 27th March 2011, 16:01

Is an updated download available yet to fix the seek bug?

Chumbo · 27th March 2011, 19:00

@BetaBoy,
I found a playback corruption issue on a file I edited. Playing it using either ffdshow or MPC decoder has a fairly clean break at the edit point where CoreAVC 2.5 shows much corruption. Small sample here.

oddball · 27th March 2011, 19:12

Anyone got a direct download link? Your crabby portal does not recognise my email. Why paid up members should have to go through your portal to download the codec (which requires a registration number regardless) baffles me.

BetaBoy · 27th March 2011, 20:34

We are working on a quick followup release once we are confident the current reports are fixed.

We will send an update notice as soon as it's available. We already have an RC build compiled that we are testing.

BetaBoy · 27th March 2011, 20:37

Oddball... Do not ask for a direct download link... And you will need a new corenumber as they have changed with 2.5.

PM me with your info and I'll take care of it.

BetaBoy · 28th March 2011, 03:16

We are sending a test build (v2.5.1) to those who submitted support tickets on the seeking, graphstudio, and mediaportal bugs.

ajp_anton · 28th March 2011, 13:02

What advantages does CoreAVC's DXVA have over for example MPC-HC's internal one?

desta · 28th March 2011, 14:56

I've just upgraded to 2.5. Before doing so I quickly played some of my own 1080p encodes with 2.0 and all was fine. After upgrading to 2.5 I now get jerky, stuttered playback with 1080p mkv's. If I disable cuda then playback becomes smooth. 720p and below is fine with and without cuda.

I've opened a ticket through the portal.

robpdotcom · 28th March 2011, 16:01

I updated to 2.5 yesterday, and when using DXVA I'm getting a corrupted image (not sure how to describe it, I can get some screen shots if necessary).

I haven't seen anyone else describe anything similar. Should I open a ticket, and, how do I open a ticket?

What NVIDIA drivers do you have installed? Have up upgraded to the newest ones?

We have received other similar reports... if you have a sample that shows this it would help trying to see whats going on.
