AviSynth was not detected on your computer!
This application will now exit.

Aww (running 2.5 on Windows XP 64-bit, so avisynth.dll is in C:\Windows\SYSWOW64)

After some false starts in the past I am very interested in seeing this!

Allright! I`ve been missing something like this also, especially one that takes a wide range of input formats. Will it be kind of like windows movie maker? (just better of course)

@davidhorman

I removed the check for avisynth. Download this file:

v1.0.1 Beta

Can you check if the following registry key exists on your computer?

HKEY_LOCAL_MACHINE\SOFTWARE\AviSynth

This key is supposed to exist if Avisynth is installed correctly.

[teejee2008]

@ivar

I'm taking some ideas from windows movie maker but it won't be exactly the same
So far it can do only basic editing like cut/copy/paste etc. I have not added any filters till now.

[osgZach]

This looks like something to follow. Not sure if I have much use for it right now but I will keep following development.

Any plans for GPU acceleration / filters ?

Can you check if the following registry key exists on your computer?

HKEY_LOCAL_MACHINE\SOFTWARE\AviSynth

This key is supposed to exist if Avisynth is installed correctly.

It's not there, but there is:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\AviSynth

[Zarxrax]

What exactly are your plans for this? How far are you willing to take it, feature-wise?

I'm getting an error too. v1.0.1 beta with 64bit mediainfo.dll Running on windows 7 64bit.

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.DirectX.AudioVideoPlayback, Version=1.0.2902.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.


Also, I find it ironic that in a video editor based on avisynth, it can't import avs scripts

I have that, under WinXP SP3, and I get "Microsoft .NET Framework - Unhandled exception... Could not load fileor assembly 'Microsoft.DirextX.AudioVideoPlayback'" etc etc

with a very similar (same?) list of exceptions to those seen by davidhorman

Cheers,
David.

@teejee2008

Looks very promising, thanks!

Have you taken a look at AvsP? Might be worthwile to contact the author (qwerpoi) and see if you can combine some of your work.

[Gargalash]

Very interesting!
May I suggest the option to apply a external set of filters from an .avs file to the video? This way people will easily load and use their favorite tools and it will probably be a simpler way to add complex filters.

Good luck with your project.

[MadRat]

I've been wondering when someone would make an editor like this.

[teejee2008]

That looks like the correct key.
There should be two values under that key:

(Default) = "Path to avisynth's install folder"
plugindir2_5 = "Path to plugins folder"

Can you please confirm this?

This program has not been tested on 64-bit windows. I have no idea why those exception are being thrown. I don't have a copy of 64-bit windows now. I'll test it later.

[teejee2008]

All those people who are getting 'Microsoft.DirectX.AudioVideoPlayback.dll' not found error, please install download the dlls from the internet and put them in the application folder. You will need two DLLs:

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

[wonkey_monkey]

Can you please confirm this?

I can, those paths are present and correct. If I can be of any other help in testing x64, let me know - though from the sound of it, my problem (beyond the now-disabled AviSynth detection) is the same as 2Bdecided's on 32-bit.

As far as I can. I have never made an application like this before so I can't make any promises. I'm adding audio/video filters now. After that i'll decide what to do next.

Parsing an avisynth script and loading it is an insanely difficult task. So i'm using an XML based project file for saving and loading settings.

[teejee2008]

@davidhorman

Microsoft.DirextX.AudioVideoPlayback.dll can be downloaded from the internet.
I have a copy of XP. I'll install it tomorrow and see if I can find the problem.

[wonkey_monkey]

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

I have both in C:\WINDOWS\Microsoft.NET\DirectX for Managed Code\1.0.2902.0 - should they be somewhere else?

Edit: sorry, your post may not apply to me, I'm having different errors.

David

[tin3tin]

Wow - you're doing what so many people have talked about for years...

v1.0.1 Beta works runs fine here on Vista(Used run as Admin...)

Now, how can we help?

There are Tango icons for NLEs here.

Some bugs:
- I'm getting an error thanks to sample_type=32bit, which should be sample_type="32bit" in the blankclip function when importing other than mpg(avi, flv). I'm using Avisynth 2.60 beta.

- If I split a clip into two clips: A and B and change the order to B and A the B part will come out black and silent.

On features:
Locking/unlocking video and audio is a must IMHO.

Import of avisynth scripts.

Parsing an avisynth script and loading it is an insanely difficult task.

You know about the 'Import' function right? If you add try/catch around the Import function you can get the error message and other info on the file. Then save the info to disk by using Writefile and let your player run the script so a txt file is produced. You can then let you app read from this text file, if the script has errors/has video/has audio etc.

To make sure that variables in the imported scripts will not interfere with each other you should use the import("avisynth_script.avs") from within a function.

When you got that part down. You could add AvsP as an external tool to allow users to open the scripts up in and edith them and when they colse AvsP(after saving the script under tha same name - just recheck the script for errors.

I totally misunderstood what Zarxrax was trying to say. I thought he was talking about building a project from a avisynth script.

Importing an avisynth file as a source media can be done. I'm aware of the Import function. 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.

All the video filters displayed in the GUI will be loaded using definitions from an XML file. I'll need help defining all the video filters. There are more than 100. I'll add a simple editor for editing the definitions.

Those icons are very good. Thanks for the link

I'll fix it

you can position the audio and video clips by dragging them along the timeline so that their start position are aligned together. You don't need to worry about the audio and video going out-of-sync. Locking the audio and video clips together so that they can be moved as a single unit will require some work. I'll do it later. its not a priority right now.

I'll add it.
