Thumbnailing MKV's on x64 Windows 7

[Shark007]

On x64 systems, utilize the x64 Settings Application.

go to the H264 TAB of the Settings Application
choose to unlock the Microsoft Decoders and proceed to select FFDshow for playback in the Microsoft players.

Next, clear your thumbnail cache by utilizing the Disk Cleanup Tool - to find it, navigating the startmenu
Accessories | System Tools | Disk Cleanup

The tool defaults to your Windows Drive, click OK
In the next window that appears, be sure the box next to Thumbnails is checked, press OK
Reboot your system.

If I do this then thumbails work fine - however - for VC-1 codec I require to use the CoreAVC as ffdshow is pretty shaky/jerky. If I do this then Windows Explorer crashes whenever it trys to generate a thumbnail.

I've tried this several times, rebooted but to no avail.

Any ideas?

Many thanks

Using a current release. Open the x64 settings app and then on the H264 TAB
select CoreAVC and also select the checkbox below it.

Thanks for getting back to me so quickly.

I did already have it set up like that. I've tried with and without it checked.

Current settings are:

Use FFDshow's codec: Do not use FFDshow
Use MPC-HC DXVA codec: Do not use MPC-HC codec
H264 codec in DirectShow Players: Use CoreAVC codec

Enable FFDshow postprocessing while using CoreAVC to decode MKV's: checked

Below that it does say "CoreAVC will crash qedit.dll if thumbnailing". Is this anything to do with it?

Thanks in advance

The order the buttons are pressed, matters.
use Reset All
go to the H264 TAB, press use CoreAVC codec
and afterwards select the checkbox to Enable FFDshow postprocessing while using CoreAVC to decode MKV's

This specific order (not including reset all) setups Coreavc for MKV's containg h264 (avc) and at the same time uses ffdshow for the thumbnails

I did as you said and then rebooted but to no avail.

The VC-1 files generate a thumbnail fine but then if I look at something like:

- 1080p DTS/x264 or
- 720p x264

Then Window Explorer crashes.

I've posted a screenshot to show you that it's set up correctly.

Below is the exception details wrote to my Event Viewer:

=============================================

Faulting application name: Explorer.EXE, version: 6.1.7600.16404, time stamp: 0x4a765771

=============================================

Without knowing how the code works I'm guessing it's not picking up that the box is checked?!?

PS - This is by far the best codec package I've come across and I really hope we can suss it out.

Many thanks

Did you install Haali that comes with CoreAVC?
If so, you will need to start over

Uninstall my software - both x86 and x64 (x64 1st)
uninstall Haali, and core avc

re-install Coreavc, without haali
Install my software and proceed to setup the H264 TAB

No I didn't - however I did previously have it installed.

I uninstalled CoreAVC and FFDshow. I looked to uninstall Haali but it was in the program list (remove programs). So I installed CoreAVC and then your apps.

However I've just seen it's in my Start Menu but it's not in Remove Programs. Does it not uninstall with CoreAVC?

It's getting late now so will do what you said tomorrow after work (I'm in UK and it's midnight). I will get back to you as soon as I've done it.

Thanks - again - for all your help
