Win 7 7048 x64 media player Crashes

[fakeasdf]

Well, I've installed Windows 7 7048 on two different machines and both of them are crashing when I open up media player.

Faulting application name: wmplayer.exe, version: 12.0.7048.7000, time stamp: 0x499e5537
Faulting module name: mf.dll, version: 12.0.7048.7000, time stamp: 0x499e6252
Exception code: 0xc0000094
Fault offset: 0x00264eb2
Faulting process id: 0xae8
Faulting application start time: 0x01c99d4c6604910f
Faulting application path: C:\Program Files (x86)\Windows Media Player\wmplayer.exe
Faulting module path: C:\Windows\System32\mf.dll
Report Id: a9240250-093f-11de-a86d-001c235b7f39

After I debugged it in Visual Studio it turns out it's an unhandled division by zero...

It isn't a DRM issue, I've even had it recreate the DRM info without any avail. Anybody else seeing this issue?

Nope, mine's running fine. Both 32 and 64 bit WMP. Did you upgrade install or clean install? Have you ran SFC yet?

 

[fakeasdf]

I clean installed on both of them. The issue didn't arrise until I added my music to my music library. I guess it's possible one of my songs is causing the issue. I didn't have any issues until 7048 tho with the same libraries. I also didn't have any issues with media player in 7000 or with 7022. I'm not totally sure, but Microsoft has gotten like 100 reports from me today on it

 

[Owngasm]

I had the same issue, after watching what letters it was crashing at I was able to locate the folder that was causing it to crash.....for me it appears it be my Fatboy Slim =( my guess is that it's a some kind of odd character in the Tag that is causing it to crash. Still looking into it

 

[mdsharpe]

I have had the same crashes. Quite disappointing!
Deleting the library does not help.

Owngasm, how did you work out which folder it was erroring on?

 

[johngalt]

No crashes here either in W7 64bit

in addition, it works well playing all sorts of formats using Shark007's W7 codecs....

I spent a couple of hours watching a Japanese Anime series Claymore that is compressed in MKV format - ho issues at all. Even was able to use my WMC remote control to control the video from across the room.

Owngasm, how did you work out which folder it was erroring on?

I have the same problem in 7048 and would also like to know how he determined the offending folder. I've got 100 of these errors in 24 hours, all caused during library update from my server based music folder.

Edit: found the bad file - Braveheart Soundtrack Main title. Interestingly, highlighting that file in the network share folder containing My Music crashes Explorer in 7048/32 on both computers I have now running that build, but doesn't crash Explorer on any of my Vista boxes. I didn't note any problems with this file when I had 7000 installed.

Finding the bad file took some time, since my Music folder is subdivided into categories - in this case, Soundtracks. Updating the library in 7048 Media Player stopped in that folder. Then I pulled the entire folder out and reloaded files until I hit the bad one that caused Media Player to crash.

If you have your music folder arranged more simply - Artist/Album, for example - finding the "bad" file will be easier.

I checked the tags on the errant file and didn't see anything obvious that might have caused it to fail, so it's a mystery, but a corrected one.

Still crashing in 7057

Yeah, so I just updated to 7057 and it's still crashing, I'm not too worried, I can just use some other media player for now. I'm sure they will fix it before the release.

 

[mdsharpe]

Yep, the problem is indeed still there in 7057 x64.

I have established that my problem file is not artists folders A - K,
so now I am systematically moving folders back into the music folder and letting WMP update its library one letter of the alphabet at a time.

 

[fakeasdf]

I'm not sure if it attached my file or not, but I found the "bad" song and I'm going to either upload it here, or upload it and link it here for those of you that are having a hard time believing it's crashing and go ahead and try putting the file in your music library, or even looking at the file in explorer.

 

[mdsharpe]

i found my bad song too. one tune in my whole library.

i just deleted it since i don't like the song anyway!

 

[fakeasdf]

I'm not sure why this thread is marked solved. It definitely hasn't been solved, you can sift through your songs and remove the perpetrators by using dos or some other program that doesn't use the microsoft explorer to view files, but those mp3's cause explorer, wmp, wmpnetworkshare service, open dialogs etc to still crash which I would consider quite an unsolved issue, an X-File if you will...

 

[Airbot]

Fine, I take the solved mark away, no need to get your feathers ruffled.

 

[Dragonfly]

Maybe you need an "Explained" mark in your bag of tricks. :roflmao:

I was having this problem too, rather than tediously going through my collection bit by bit here's an easier method:

1. Get Process Explorer
2. When media player hangs just leave it on the screen in it's crashed state.
3. Open processexplorer, go to "Find Handle or DLL"
4. Search for "mp3" (no quotes)
5. You should see the process wmplayer.exe and at least one handle to an mp3 file in your collection.
6. Delete said file from your collection (you'll have to close the crashed media player to allow the file to be deleted).
7. Rinse and repeat until Media Player no longer crashes

Yaa, I got ahold of someone working on the Windows 7 team, he said he'd take a look at the issue... Saaweeet. I love Win 7...

 

[fakeasdf]

Hey guys, it was fixed in 7068! w00t

 

[webhouse]

working for me...!!!tnx....

 

[Tw00t]

Hey

This is my first reply to anything in this Forum but i figured out how to fix it on my computer so I thought I would share. It look's like it was a corrupt mf.dll

you can find it by going to C:\windows\system32\mf.dll

you will need to take ownership of the file to replace it which I am not going to tell every one how to do. If you can't figure it out you probably shouldn't be messing around with the system32 file.

Since this is a topic for windows 64bit I will post the link I found for it but if you are on 32 bit find your matching one because versions matter here.

64 bit only http://down.dllexedown.com/100723/12_seven64_eng/Windows/System32/mf.dll

Any ways I hope this helps some one because I spent a couple of hours figuring this out.
