FFDSHOW & error message

[[)370|\|470!2]

After installing latest ffdshow(20050703MSVC71), i got some errors when exiting
some programs, like gspot, vdubmod. though, no errors when opening video, only
when closing(which is a bit annoying though). Also, gspot claims that i don't have
codec for H.264, even though it renders it fine(ffdshow.ax). Thx in advance.

PS.: To Mods: i was unsure where to post this, so don't slap me 2 hard :stupid:

I also had a very similar problem after installing that ffdshow build. I could reproduce it just by openning and closing DXDiag. After I unistalled ffdshow 20050703MVC71 the crash went away.
I also went back to ffdshow daily build 050303 (from SourceForge) and couldn't reproduce the problem, so it was specific to that build and not a generic ffdshow issue.
Now I am back to latest CD build (050727) and it's not crashing DXDiag anymore. So I suggest you to upgrade too (specially if you need the latest features in H264 decoding). You can get it from many mirrors:

BTW, I run Windows XP SP2.

Yea, looks like it's fixed in newer builds

I didn't want to make a new thread for this, but this one seems related enuf (hope it gets some attention).

Anyway, I've been experiencing random crashes with ff_acm.acm. Every once in a while, when i'm browing around in windows explorer and come to a folder with some (seemingly any) A/V media in it, explorer will crash and it says it's ff_acm.acm's fault. I really have virtually no idea what's going on here; I went to the FFDShow audio decoder config and disabled everything, and yet the problem persists.

I'm not sure what ffdshow version this started with, but it became more apparent in the last few months. I usually check and update my ffdshow regularily and am using the 20050822MSVC release now.

I am using ffdshow 20050822 (cd) and doesn't even seems to have a file called "ff_acm.acm" (samed applied to 20050803).
Tox|k, couldn't this file be a leftover from a previous installation??

[celtic_druid]

It is installed to your sys dir.

[lrms]

@cd: so the installer does include it? Well, it just wasn't installed in my system.
Maybe it was because I didn't check PCM decoding in the installer?? I thought that would just affect the default handling of formats, and not which files were installed.
Anyways, if it causing crashes, I don't regret if by accident I didn't choose to install it :)

[celtic_druid]

First I have heard of it crashing. On the other hand the problem of crashing while exiting GSpot, etc. was a common problem.

A colleague of mine has the same problem in Windows 2000. It is on our computer in work, I'll have a closer work on the problem on Monday, if I won't forget.

Look here (http://forum.doom9.org/showthread.php?t=98746), I just had very similar issue, but it's solved now.
