Cannot connect lav video decoder with asf wm writer on windows 8.

[GoogleCodeExporter]

Hi, I have found strange situation on windows 8 using LAV Splitter source and 
LAV Video decoder.
I built graph as below:
Lav splitter source -> lav video decoder -> asf wm writer
                    -> lav audio decoder ->

When I place something in graphedit then encoding does not start. When i made 
program which contains such graph then i cannot connect lav video decoder with 
asf wm writer (0x80040217 HRESULT is returned during filter filter connection). 

I have tested my application on xp, vista and 7 and it works properly only on 
windows 8 problem occurs.

In the attachment you can find my graph and profile (wm asf writer), generated 
by my program.

The input file was in mp4 container, with mpeg4 video codec, and aac audio 
codec. This also occurs when i used mpeg2ts container and mpeg2 video codec.
It seems that video decoder make a problem because:
-this fails
wm asf reader - > lav video decoder - > wm asf writer 
-this works
wm asf reader - >  WMVideo Decoder DMO - > wm asf writer

I tried to find a reason for this, but all i see is that for some reason the 
graph is not started at all, but i couldn't find any reason why not, and none 
of the checks in LAV triggered that would indicate anything had gone wrong.

My guess is that the WM ASF Writer just doesn't like something specific, but 
without knowing what that is, it will be extremely hard to find out what.

Additionally, i don't have Windows 8 on any of my PCs, and debugging with 
remote debugger in a VM is not very productive. I would suggest to stick to 
Windows 7 ;-)
