Avisynth - DirectShowSource "CoInitialize has not been called.."

[hristoff2]

Hi guys, I'm getting this error:


Avisynth error:
DirectShowSource: Could not open as video or audio.

Video returned: "DirectShowSource: couldn't create filter graph:
CoInitialize has not been called. "

Audio returned: "DirectShowSource: couldn't create filter graph:
CoInitialize has not been called. "

..when huffing with avs2yuv, mencoder or opening anything via directshowsource in vdubmod. Vdub itself works for some reason, I can use direct input for x264 but it's way faster with prerendering.

Any suggestions?

I don't want to huff via vdub because I can't do prerendering and encoding to x264 in one step and it's necessary that I'm at the pc to start the encode (x264) - that's ok but not perfect. (And I didn't find out anything about that error..?)

Report versions anf other information.

Avisynth 2.57 retail, 2.58 (beta) - same error.
Windows XP Pro
Intel Core2Duo


Tried different versions of vdub, vdubmod, avs2yuv - same result. At the moment installed: newest vdub & vdubmod

That should be everything which would matter, if not please ask for it.

Always with the same file or format? Sounds like a bad directshow filter is calling CoUninitialize one time too many. The log may or may not help pinpoint the problem, I'm not sure. (logfile="somefile",logmask=-1)

[hristoff2]

This happens always with DirectShowSource here, the error isn't source depending - if it was, I wouldn't mind asking here :)

Opening the script with vdubmod, getting the error:

This is failing at line 1515 of directshow_source.cppCheckHresult(env, CoCreateInstance(CLSID_FilterGraphNoThread, 0,
CLSCTX_INPROC_SERVER, IID_IGraphBuilder, (void**)&gb),
"couldn't create filter graph");And yes this will indeed fail if COM is not initialized. Question is how is your COM environment getting released, because Avisynth initializes COM as part of it's startup. There is a longstanding development thread DllMain & CoInitialize/CoUninitialize (http://forum.doom9.org/showthread.php?t=48279) about where best to initialize COM and even whether Avisynth should do it at all. Perhaps we should be doing the calls inside AviSource and DirectShowSource. I will cross reference this post in that thread.

[hristoff2]

Any suggestions what could've changed anything leading to this? I'd assume it's something specific here because I've got two almost identical systems (1x web/game/encode | 1x encoding).

They're identical (codecs, dshow filters, avisynth - everything about video).

And thanks for making this public in the developer's thread.

[Richard Berg]

Same version of VDubMod? That's probably where the bug is.

[hristoff2]

No, not the same version and both report the same error. (sorry forgot to mention that)

Vdub itself works on both though, avs2yuv doesn't work. (on both)

[shadowhaze]

I've got the same problem as hristoff2. If I try to use directshowsource in avisynth to open a non avi file, I get this error. This happens with VDMod, HCenc, AvsP. As with hristoff2, VD seems to work, but I'm not sure it's at 100%. I'm running XP SP2, avisynth 2.57 (now 2.85 alpha) and use the latest k-lite "Mega" codec pack

I've read this thread and the avisynth development thread a few times, searched on the net for a solution, installed avisynth 2.58 alpha (as there was some change to coinitialization), re-installed my codecs, and changed the settings on ffdshow but nothing worked.
This seems to be the solution http://forum.doom9.org/showthread.php?p=276372#post276372, but I have no idea where to copy it and what to delete. I'm a complete novice when it comes to writing or modifying software.

I would very much appreciate any assistance on this problem. I'm sure hristoff2 and others with same issue would be grateful as well.

Thanks

I got a report now, according to the log file I received, VirtualDubMod succeeded to open a basic script with DSS/WMV but x264 gave this error. IIRC the same person who reported this reported problems with the open/save file browser and another problem with drag & drop, since the shell uses much COM and nobody else ever reported any of these problems to me before in the last 7 years I'm suspecting something COM related being broke on this systems, probably something installed that broke something or some system setting.

[IanB]

The current algorithm regarding COM is to initialise it on IScriptEnvironment creation.

If COM was already initialised, i.e. use count now >= 2, then release Avisynth's extra use count and take no further action regarding COM.

If COM was not initialised, i.e. use count now == 1, then keep Avisynth's active use count and remember the current Thread Id. On IScriptEnvironment deletion if the current Thread Id matches the saved Thread Id then release COM. If the Thread Id does not match then tough luck, the process just leaked a COM instance. This is better than releasing COM for the wrong thread, which can cause all sorts of problems including crashes.

Your problem sounds like something is buggering up the COM use count for the current process and/or thread.

[stax76]

Do you have a idea how to find out what the culprit is? Maybe everybody having this problem posting which libraries are loaded (as shown by Process Explorer).
