Winamp is apparently fucked.

[Bobbias]

I just posted a thread on the winamp forums. I did some digging, but came up with nothing, and I'm really confused as to what's going on here. I REALLY hope I don't have a virus or something :/ Both the important DLLs are trusted, according to process hacker.

I know I have enough programs that I could use for music (Media player classic, WMP, Foobar2000, VLC, GomPlayer, and Zoomplayer) but I prefer winamp over all those when it comes to music, especially streams, like di.fm...

halp!

Based on your call stack, I'd say that the main thread is waiting for a thread to finish.  APC is a method for managing asynchronous threads in Windows.  Considering it's happening on load, I'd say it's either having an issue loading your settings, your library, or your plugins.  Something's getting the thread stuck in a tight loop (I'm guessing you have a dual core processor, hence why it's locked at 50%).

I had something similar happen to me (I believe my issue was with loading my library) and going into %appdata% and killing Winamp's directory fixed it.  Failing that, it wouldn't hurt to kill Winamp completely (uninstall and remove its directory) then reinstall it.

[Bobbias]

Done both of those, still not working :<

I've actually considered attaching ollydbg and seeing what is going on, but knowing my skills with a debugger, it'll probably take me 3 hours to figure out something that would have taken anyone with actual skill about a minute to figure out :/

And yes, thank god for having a dual core system.

When Winamp took a shit on me, I was running a single core Pentium 4.  Luckily, it seems like Justin Frankel designed the threading code and it managed to remain untouched from the other chuckleheads that worked on it, since it was designed competently enough to not bring my system to its knees.

Odds that it didn't work.  That's pretty much the ultimate CTRL-ALT-DEL when it comes to Winamp (and Firefox).  Maybe there's something left in the registry.  Also, make sure to check both your local and roaming application data directories, since things sometimes hide among both of those.  Also, make sure that it didn't put anything into "Common Files" under your application data and program files directories; that can sometimes cause issues.

Also, see if you can hunt down an earlier version just for testing purposes.  There might be a shiny new bug in the latest version.

Solved! (sorta)

Apparently there was a gen_winamp.dll plugin that shouldn't have been there. I have no idea what it was for, though I recall seeing it in my old setup. But when I loaded winamp up in ollydbg I got a message saying that the entry point in that dll was not in the code section, and then after clicking through that there was an Access Violation caused by that module. Deleting the file seems to have solved that.

[Spectere]

Odd.  I don't even see any mention of gen_winamp.dll from a Google search, outside of your post on the Winamp forums.

I kind of wonder what it is.  Would you mind sending a copy over to me so that I can check it out?

[Bobbias]

Here you go. Your lucky I didn't just clear out my recycling bin. I'd be interested in figuring out what it is too.

I guess it's not really necessary, but be careful that this isn't a virus or something, lol.

Looks almost like it's a com interface for winamp or osmething.

[Sneaky]

Could this dll be part of an old skin you had downloaded? maybe very incompatible with the new winamp

[Bobbias]

Nope. First, it's named like a plugin, second, I don't use skins other than the classic skin (I usually install with modern skin support disabled).

My money's on it being an old COM interface for controlling Winamp with those COM methods. Doesn't explain it exploding when winamp tried to load it though.

[Spectere]

My money's on it being an old COM interface for controlling Winamp with those COM methods.

Yeah, I'd have to agree.  I do remember there being an interface for getting general information from COM-aware applications, so perhaps this is it.

Still sort of odd how Google turned up zilch for it, though.

[Bobbias]

Agreed (I googled it as well). I even tried googling for a COM interface, but google seemed to be ignoring my intentions and not looking for COM related stuff (or at least not turning any up... Google needs to recognize more upper-case abbreviations and prioritize them when searching... It's a pain when I search for say, C# and get stuff for regular old C, etc.)

AHA! http://forums.shoutcast.com/showpost.php?s=420c9c8eec57443aa44b3f5eaa8c7095&p=2572123&postcount=5

And googling "Winamp COM Interface" brings up the odd mention of itamong a lot of "Winamp.com) interface"... Google needs to realize that sometimes I want to exclude anything that isn't EXACTLY what I have in quotes :/

[Spectere]

Oh, to force Google to take what you type almost verbatim (it doesn't make it case-sensitive), use +"this format".  If I search for, say, "Spectere," I would have to use that to make sure that "spectre" and "specter" don't show up.
