GraphEditPlus can't start

[mailed]

I have some problems with GraphEditPlus.
I have been using it till February, roughly, without problems.
Now, every time I launch it I have an exception: I can press CONTINUE but
the program hangs and I cannot do anything.
I can launch Graphedit standard and DSGraphedit without any problem. My OS
is Vista Home Premium.
Can you help me?

This is the text that I have in the exception box:

System.ArgumentNullException: Il valore non può essere null.
Nome parametro: key

Please try the latest version:

That problem was solved a few months ago.

I have a similar problem.
Graphedit hangs when I try to render a file.
I can insert filters and make my own path, but it hangs if I try to render files.
My OS is a 32-bit Vista Premium.
Is there a log that I can refer to when it hangs this way? Didn't come to my notice so far.
Standard graphedit works perfectly fine though.

Let me know what more details you need to troubleshoot this.

Thanks in advance.

That's weird. Are you using version 1.2.1?

[tskd]

Yes, I in fact downloaded 1.2.1 a second time and retried before posting yesterday.
I made sure to close the standard graphedit before I ran GrapheditPlus, just to be on the safe side. Also tried rendering different files and it hung nevertheless.

But I have enabled popping up of filter icons on my taskbar. In the case of rendering a mov file, I can see the Haali Splitter pop up on my taskbar, bottom right, but the graph does not render anything and hangs.

Hi,

Any thoughts on this? Are there any known issues with Rendering files using GraphEditPlus? Does an already installed filter cause Directshow related issues with GrapheditPlus?
I use:
1) ffdshow decoders
2) Haali Matroska filters (Splitter, Muxer, Sink)


Thanks

Sorry for the delay.
Unfortunately nobody met this behavior before and I don't have any ideas why this happens.
I'll make some kind of log in the next minor update (coming out today or tomorrow) to try to understand the reason.

One little idea: in ffdshow there was a list of allowed applications. In some versions it was enabled by default, in some disabled. Check out ffdshow options, probably it's enabled and GraphEditPlus is not in the list..

Version 1.2.2 is out.
After install you'll find a batch file in the program folder which runs GEP with "log" parameter. In this mode when you render a file GEP will create a text file "gep_log.txt" in the same folder as the rendered file. Show its contents so I could understand on which step it hangs.

Hi,

Downloaded v. 1.2.2 and ran the bat file.

my gep_log is as below:

graphBuilder.RenderFile C:\Users\admin\Desktop\onion_video.mpeg


as you see, the render file is what i am trying to do.

about ffdshow, gep is not among the applications ffdshow can't start with on my machine. so, that should not be the issue. Plus, it seems to be only me that's experiencing any problem, as I don't see any other posts.

Please enlighten. Thanks!

Here's corresponding source code of GraphEditPlus:

Code:

            try {
                log("graphBuilder.RenderFile " + filename);
                int hr = graphBuilder.RenderFile(filename, null);
                DsError.ThrowExceptionForHR(hr);
                log("RenderFile ok");
            }
            catch (COMException e)
            {
                ShowCOMException(e, errmsg + filename);
                return;
            }

It seems that it hangs inside DirectShow method RenderFile and I cannot control what happens there. Something is really screwed at your machine...

Try following experiment: in a new graph choose "Add source filter" from context menu, select your file. Then try rendering its output pin. Does it hang this way?
Also, try viewing matching filters for the output in of inserted source filter.
Also, ensure that the source filter inserted this way is "File source async" and not some third-party one like Nero's.
