"No function named mpeg2source" on Win 7 64bit

[Mister Hatt]

Just gonna point out that for 64-bit FFMS2 it depends which plugin you have. If you have the developer approved one, you do not need LoadCPlugin. If you use the one from the avs64 project, then you DO need LoadCPlugin. I would suggest the officially approved one which is loaded like any normal plugin. TheRyuu compiles it every so often in Darkhold and when it's stable it gets added to the FFMS2 site.

I think I may be going about this in entirely the wrong way. But I'm lost.

I just downloaded the x64 avisynth and virtualdub. My script, which works fine in x32 version of each program, comes up with "There is no function named DirectShowSource".
I downloaded all my x64 directshow filters here. I was unsure where to place them though.
I guessed (most likely wrong) and put them in the plugin64 folder of Avisynth. Still nothing. Added the LoadPlugin line, I get an error that it is not a plugin.
I tried LoadCPlugin instead, I got unrecognized exception.

Someone please help me, I know I'm being stupid. Where should I have put the directshow filters?

DON'T use directshowsource. It's not frame accurate. Use FFVideoSource instead. Or, if for some reason you really really need to use directshow to load in avisynth (you most likely don't, probably), use DSS2, which is frame accurate. I'm not sure where to get a 64bit avss.dll (the one to use DSS2), but I'm positive it's around somewhere. As for FFVideoSource, there have been links to it (ffms2) in this thread.

Still, however, directshowsource is an internal avisynth function, so if it is not working, then I think something might have gone wrong when installing avisynth, and I'd suggest a reinstall.

I saw ffms2 mentioned, but no links to it... Quick google and nothing. Am I blind?

I followed the avs 64 readme file.. Not sure what could've gone wrong... But I guess I will try again.

Look for "kemuri-_9's FFMS2 (The Fabulous FM Source 2)" in there. Also, as qyot pointed out:

64-bit FFMS2 is a C-interface plugin. You have to use LoadCPlugin, not LoadPlugin.

Remember to do:

Code: Select all

loadcplugin("ffms2.dll")
ffvideosource("file.mkv")

or whatever applies to your specific case.

As for the install, I don't personally have a 64bit os so I never tried 64bit avisynth and can't help much further... perhaps it really is not internal for 64bit avisynth, but it would seem weird, that's why I'm assuming something went wrong.

Awesome, it worked! Thank you.
