how to import avisynth.dll

Hi, this might belong to the development section or even a c++ forum, but I wasn't sure, so I post it here. How do it import the avisynth dll in order to make it open an .avs or accept the commands in an avs from me and give requested frames to me? (like in vdub) So basicly, how can I be the one the frames are served to? I looked at the vdub source, but didn't understand how it was done. I see it getting info from the registry (which I know is necessary), but I just do see whats going on. I'd ge greatfull for any hint (maybe it's been discussed semewhere else and did'nt find it) thanks jonas

take a look at my hp. there is a small delphi example that uses an intermediate c++ dll to access avisynth.dll.

thank you aquaplaning, I actually want want to create an intermediate dll either. I looked through your source and there are still quite a lot of questions.... I still don't see the avisynth dll loaded, but to me it seams like an old version (v1.0b is the oly sourcecode I'm a little familiar with) of avisynth with the added dll exports; is that so? So, if it is, is there anyway of loading the avisynth.dll, rather than building it into the intermediate dll? becuase I don't want to be stuck to 1 version of avisynth. hpe to get some more help from you :-) jonas

You should be able to open avisynth scripts, just like regular AVIs, through the VFW , or whatever wrapper is available for the language you're using. Another way, if you're doing C++ (or want to write a wrapper for your language), is to use the only function exported by all version of avisynth: CreateScriptEnvironment. It returns a ScriptEnvironment pointer; with it you can do many things, in fact much more than simply opening a script (but you can do that too). Look in avisynth.h for details. The most useful method is probably Invoke, which allows you to call any script function or filter in avisynth directly (among others, the "Import" function to open AVS files).

I noticed the CreateScriptEnvironment before, but wasn't quite sure how to use it, but I think I got it now. Is the avisynth.dll always in the system32 dir? And the reg entries are only for windows AVIFile API? Probabbly is like that, grr. I somehow got fixed on having to use the registry to get the position of avisynth.dll. And seeing that the registry key only keeps avisynth.dll as value I got even more confused, now it all makes sense, I hope. thanks a lot jonas

Hi, I've been reading some avisynth sources over the last few days, but I failed to find the function that lets me open an avs file. the Scriptparser is used for that, I belive, but in order to recieve frames I need a PClip I can call getFrame on, don't I, and I don't see how to get that.... sorry if this is a stupid question... thanks jonas

Here is how to obtain a PClip: To import a script: Code:
