Got this when I was previewing a .WAV file in Lister (using the mmedia plugin which is playing it in windows media player)

Another one, doing the same thing (not sure if it was a different file. Everything seems to be the same except for one item in the "raw" section.

It's probably caused by the mp3 decoder filter which you have installed. Total Commander is written in Delphi: Delphi turns on floating point exceptions (e.g. division by zero) and lets the user handle them. Microsoft Visual C++ turns OFF floating point exceptions and simply ignores them! The problem can occur when a VC++ library is called by a Delphi program, and a floating point exception occurs in that library. It would normally be ignored when called from a C++ program, but in a Delphi program it's causing a crash.

Unfortunately there is most likely nothing I can do here, sorry. All you can do is try to find out what codec is used (e.g. via Microsoft's free GraphEdit tool, and then disable that filter and use the one which comes with Windows.

I thought you are turning off floating point exceptions for plugins and shell extensions don't you?

23.01.08 Added: Disable Delphi floating point exceptions when calling OLE functions which may involve shell extensions: Drag&Drop, Context menu, Property sheet, Copy+Paste, Overlay Icons, Thumbnails, Info-Tips
23.01.08 Added: Disable Delphi floating point exceptions before loading any DLLs (Visual C++ DLLs may cause floating point exceptions because exception handling is off in C++)

[ghisler(Author)]

Yes, I do this before calling the right click menu and other OLE functions. The problem is that Lister plugins are working "on their own" - they are just hosted by the program, but windows calls them directly when windows messages like WM_PAINT come in. Therefore I cannot turn off floating point exceptions for these addons, and Delphi turns them back on every time when floating point functions are used...

How big was the wav file. I just tried s few small ones and I didn't get the error.

[wayfinder]

Boofo: the file size for one of the files that threw the error is about 1.5MB. Edit: here it is: www.yfinder.de/random/champaign%203.wav

This is the GraphEdit properties dialog:

I can't tell the mp3 decoder filter from this, let alone how to disable it... does anyone know more about the matter?

edit2:

I found this. Will setting the Merit value to "MERIT_DO_NOT_USE" suffice, or would I have to unregister the filter? Or is this something I should not unregister?

[Boofo]

Strange. I just tried that wav file in Lister and it played fine with the mmedia plugin. No errors at all.

[wayfinder]

Then you are probably using a different DirectShow filter?

Just tried it again, got this:

Code: Select all

---------------------------
Application Error
---------------------------
Exception EInvalidOp in module TOTALCMD.EXE at 0D38809E.

[Boofo]

I use whatever comes with the latest K-Lite Mega Codec Pack.

[ghisler(Author)]

Surprisingly, the analysis of the stack trace seems to indicate some other problem. Here is the trace (read from bottom up):

Code: Select all

602D7A listplug.468: ListCloseListWindow -> listplugin.ListCloseWindow(listwin)
615A5A listunit.6349: TLister.FormCloseQuery -> ListCloseListWindow
417C76 forms.3249:  TForm.CloseQuery ->  if Assigned(FOnCloseQuery) then FOnCloseQuery(Self, Result);

So it seems that user wayfinder closed Lister, which then called the ListCloseWindow function of the plugin. I guess that mmedia then closed the Windows Media Player control without stopping the player (or waiting for the player to stop), so the codec crashed because it was closed inexpectedly.

To verify this, do you also get a crash when you do NOT interrupt the player?

[wayfinder]

Yes, I do not need to interrupt Lister to get errors. Interestingly, I get two kinds of behaviour from doing exactly the same thing.

I tried it just now: I set up TC to show the directory containing the file linked above, then closed and reopened TC to get a fresh session. Selected the file and hit F3, then waited.

It appears that there are several ways it can go:

1. Lister plays the file correctly on the first try, a second play gives me the short form error message (like in my most recent post). It does not appear to matter whether I quit and restart TC between the two tries.

2. I get the long form error message on the first try (like in the original post) and TC quits ("[No]") or becomes unresponsive ("[Yes]")

I'm thinking it may have something to do with how much time there is between tries. It feels like the chance to have it work is significantly higher when I wait longer between tries.

I did not interrupt Lister during play, I only closed it when it had successfully played the file.

Here are some assorted stack traces and error messages

To find out whether the bug is in mmedia or a codec, can you try a different plugin, e.g.
http://www.totalcmd.net/plugring/AmpViewClassic.html
?

After installing, make sure to move it in front of the mmedia plugin to give it priority.

If that crashes too, it's a codec problem. In this case, you can use this plugin:
http://www.totalcmd.net/plugring/ampview.html

It doesn't seem to rely on Windows codecs.

It doesn't seem to rely on Windows codecs.

AmpView use bass dlls but not directshow filters.

I can suggest another plugin to check: Media Show

But please note: it may crash TC if you'll change focus from Lister to e.g. Windows Taskbar, with next error:

Code: Select all

---------------------------
Application Error
---------------------------

It's not related to played file, it's a bug of MediaShow.

[ghisler(Author)]

AmpView use bass dlls but not directshow filters.

Yes, that's what I meant - I'm not aware of any problems with bass.dll, but it may be a problem with an installed codec.
