It's not a windows media file.
Open the file in Avidemux and copy it into an mkv container.
The audio is screwed up so you'll have to open it in Goldwave and stretch the audio to match the video, use dBpoweramp (nero wave edit or foobar) to convert to aac and mkvmerge to create a fixed mkv or yamb to create a fixed mp4. |

MediaInfo show that it is a Windows Media file and VLC can play it properly.

Mediainfo sees it as WMV because the extension says wmv. If it said AVI, then Mediainfo would see it as AVI. If it was a true WMV file then it would say VC-1 and WMA instead of AVC and AAC.
VLC has it's own splitters and codecs so it can play just about anything. I assume the same applies with Avidemux since it is able to open the file and copy to a different container. It failed on just about everything I tried including Windows Media File Editor. |

Try rename it to AVI, MediaInfo still say "Windows Media" (it doesn't use the extension).
It doesn't work with normal players because the Microsoft splitter that come with Windows XP (not sure about Win Vista/7) doesn't play properly H.264 in WMV container.
Many people also doesn't like H.264, AAC, Vorbis in AVI but it works fine (it just depend as how good is the program that do it).

I have no idea how they even got h264/aac into a wmv container. The only thing I've found that works is the copy command in ffmpeg but the file I created would not play in MPC-HC. Asfmuxer crashes when trying to mux h264/aac and wmvmuxer will not mux the files but wants you to pick a profile to encode to wmv.
EDIT: I tried GDSMUX from haali and it did create a h264/aac wmv that plays correctly. It will not seek but it does play in sync. Mediainfo shows it as matroska though.
Obviously, there is a way to get h264/aac into a wmv container but I don't have a clue how they do it. Not sure why anyone creates files like this though. |

I think he (ale5000) makes these bizarre things just to give me more work. 
The plugin crashes (divide-by-zero) because the AAC audio format has its nBlockAlign field set to zero. I would say this is badly muxed for that reason. But even if nBlockAlign wasn't zero, I bet it would still not work right.
It would involve a huge effort on my part to fully support H264/AAC in the WMV plugin, and I believe it would be a waste of my valuable time. I never see things like this in the wild.
EDIT: I will at least fix the crash in the next version by checking that nBlockAlign is nonzero, although this will effectively skip that audio stream.

It isn't like this 
There are a lot of particular files in the world, remuxing programs basically allow everything.
Can't common code just be copied from one plugin to another?
I suppose that the content of the an AAC track (and also other tracks) would be similar in different containers although the header may be different.

Not really. You are talking about the ability to retrieve a specific A/V sample from the container. Problem is, each container uses its own methods for storing samples, and they are not generally compatible in my experience. The code to retrieve samples always has to be customized for the container.
Unfortunately I have no idea how AAC is stored in the ASF container and as far as I know there is no official documentation about it. I might be able to reverse engineer it, but as I said I think it would be a waste of my time. Nobody sane puts AAC in WMV.
