Avisynth Studio v1.2 Beta (OpenSource Avisynth NLE)

@davidhorman

I'll let you know if I find the problem.

The problem is that I'm using MediaInfo for analyzing imported files. MediaInfo can't read info from AVS files. I will have to use ffmpeg or mplayer which will add another 5 to 10 MB to the download package. I'll do it later.

What I'm saying is that you can use avisynth to extract information about the imported script. Please re-read my post above. There are avisynth functions like clip.width(), clip.height(), clip.framerate() and clip.framecount() too. These infos can be generated by a temp avisynth script, which can save that info to a temp file. This temp txt file you can let your app read the info from.

This is how DVD slideshow GUI does it - I can show you how I do it in wxBasic if you want.

For inspiration on how to handle multitrack, overlays and transitions in an xml format, you could take a look on how mtl is doing that: http://www.mltframework.org/twiki/bin/view/MLT/MltXml

Yes, use Avisynth to get the info, but instead of using a temporary script with WriteFile writing to a text file which you have to read back in, use the API directly via the library interface.

[tin3tin]

use the API directly via the library interface.

Can you explain how this is done in more detail?

[Gavino]

IScriptEnvironment* env = CreateScriptEnvironment();

gives you a script environment which you can use with any of the plugin API functions from avisynth.h. In particular, you can load a script by env->Invoke("Import", ...) and get properties from the resulting clip. Note that you need to link with avisynth.lib to make CreateScriptEnvironment available.

See also this post. This refers to the C API, so some of the details are different, but later in the thread, there are examples using C++ too. For just getting clip properties, the process is a bit simpler as you don't need to go as far as getting a frame.

Microsoft.DirectX.AudioVideoPlayback.dll
Microsoft.DirectX.dll

The second one should be there on your system already.
The reason I didn't include it with the download is because I thought these files are available on every windows PC. I think these files are part of the DirectX 9c Update but i'm not sure. Download it off the internet or install the latest DirectX 9c update

I have directx 11, so apparently Microsoft.DirectX.AudioVideoPlayback.dll isn't included. I have the other file. I downloaded this dll and put it in the AviSynthStudio folder, and the error about that file went away, but I'm still getting constant unhandled exception errors.
System.BadImageFormatException: is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)


This looks like an exciting application if it can be developed farther. There are hundreds or maybe thousands of people over at animemusicvideos.org who could use a decent free video editor. Since Microsoft has discontinued Windows Movie Maker as of windows 7 (the new WMM Live can not even be classified as a non-linear editor), there doesn't even exist any decent free video editing application anymore.

@teejee2008
Please replace your bass plugins v2.3, in your installer with the last v2.4
I make (2008-3-14) some changes, from v2.3 to v2.4, in BassAudio.dll (interface between AviSynth and Bass libraries) very importants to decode audio correctly.

The BassAudio.dll v2.4 is in BeHappy package and the rest in http://www.un4seen.com/bass.html (remember change the names to match with your names)

@All BeHappy (or BassAudio.dll) users, update the Bass*.dll with v2.4 in your AviSynth plugins folder.

Putting the DLLs in the application directory will throw a lot of exceptions. These dlls have to be installed correctly. You can install the DirectX 9c update on your Win7 system without any problems. It only updates the DirectX 9c DLLs on your system. It won't have any effect on your DirectX 11 setup.

I don't know how far I can take it. I'll try my best.

@tebasuna51

Thanks for the info. I'll include the updated DLLs next time.

@everybody

I have started adding video filters. It's almost done. I'll try to release a new build by Monday. It may take longer. This is what the filters window will look like:

[tin3tin]

Looks good. Earlier on you mentioned help for making filter definition files. I think AvsP got most of the covered - for setting up spinners and checkboxes. You should maybe look into the files included in AvsP.

Have you thought about how to implement transitions?

[teejee2008]

I'm using an XML based format for storing definitions. These definitions will be easy to make using the in-built editor (screenshot below)

[teejee2008]

Transitions will be difficult to implement

[Zarxrax]

Do you plan to add support for 2 (or more) video tracks? Having at least 2 video tracks would give a LOT more freedom. Transparency and fades can be done via default avisynth functions.
Also, the plugin "TransAll" will give you access to 28 different transitions.

Is the source available? What are your plans for licensing?

Another example for comparison is AVSCutter:

[squid_80]

I suggest setting the .NET project to run as 32-bit code only, that should take away some of the headaches for win64 users.

[markanini]

Maybe too early for such a request but I'd love to see functionality where I can select different crops of a clip for depanestimate.

[nibbles]

On x64, I'm getting a mass of errors when I try to run this.
