I'm using vmr9-renderless for it's required by MPC-HC to load the subtitle itself, so I don't know exactly which renderer it is, though I see coreavc decoder showing up in the filters section togerther with vmr9 renderless.

betaboy, I can't login to the core account portal. I forgot my password and I can't receive the reset emails, aol seems to be blocking them (and comcast as well, as I tried changing to a comcast email last time I had account access and they were blocking your emails too.)
I already have a support ticket open at http://support.corecodec.com/ open since the 24th but so far nobodys responed. Please look into it. The ticket number is #WMO-768-18430. Thanks.

Just tested 2.5.1 and it works well and seems to be a few percent faster (on a SandyBridge 2600) as well.
I'll test it on an Atom processor sometime where speed is more important than on a "real" cpu...

Also a bug in 2.0 which caused stuttering in some videos seems gone.

Good work as far as I can tell!

Reports so far point are close to a 4-5% increase in speed.

Im not seeing anything wrong with that clip here on my 3 systems.

Are you using Haali's splitter? or any custom renderer?

@BetaBoy,
I just installed 2.5.1 and wanted to follow up on the two issues I reported earlier.

Regarding the smooth playback issue, still broken in software decoding and worse in DXVA as no video is rendered at all (MPC-HC using EVR Custom Pres). When it worked earlier via software and was smooth, it was because I forgot I had used the Haali Renderer temporarily.

Regarding the corruption issue, no video is rendered using MPC-HC EVR Custom Pres. With Haali Renderer, corruption still there and no DXVA which is expected.

They are doing it wrong. CoreAVC 'has to' propose an output format before it even sees any of the stream info, so it has no choice but to rely on the info from the source filter.

True, but once you start to receive bitstream and detect that the bitstream contradicts the source filter's information, it might make sense to do a dynamic format change. At least if there'd be corruption or crashes otherwise.

Well it works correctly with the SW path of your decoder. Which means that even if the source filter propagates the wrong parameters the output is correct. Different story with the DXVA path as mentioned.

Other decoders work properly with wrong information too, even with DXVA.

I used Haali's splitter along with every renderer available in MPC-HC (x86 and x64).

update: Just downgraded my nvidia drivers from 266.58 to 258.96 and CoreAVC 2.5.1 now works with cuda enabled. Nvidia broke something?

betaboy, any news on getting my password changed?

Thanks madshi.... we are taking a look.

ok for the info... we are gonna look into it more.

Thanks much! I also sent a new PM with additional info, be sure to read it.

Any news on this or do I need to keep my nvidia drivers out of date to use CoreAVC now?

Just tested Core 2.5.

About performance: exactly the same as 2.0 (lol @ "faster overall" --> 139.5 fps vs 139.2 fps)
About 64-bit support: still slower than 32-bit version (133 fps vs 139 fps)

I think this release is pretty much the definition of underwhelming. Unless there's something magical about Core DXVA that's not already in 9001 other decoders (frame read-back to system memory?), I'm struggling to find a reason for anyone to get this.

Pretty much every niche that Core tries to cover is already occupied by free software:

Software decoding: DivX H264, ffmpeg-mt
DXVA: Windows 7, MPC-HC
CUDA: nevcairel's CUVID decoder

Too bad, too sad. It's too late for CoreCodec to try to remain relevant with their sub-standard products.
