Avisynth-Monitor

[johann.Langhofer]

Hello,
I've written a small extension to monitor an avs-stream. You can download for free, see links below.

Short description of the usage:
Loadplugin ("avsmon.dll")
{your script here}
MonitorFilter

What is the advantage of this Filter:
- You can prview the video (ie. during cce-conversion)
- You can determine an exact audio delay

Best regards,

Really cool - especially the audio-delay is excellent for me!

I do have some problems:

Loadplugin ("avsmon.dll") 
clip=avisource("D:\SH0DAN\MPG\Ice Age.avi").converttoyuy2()
bc=blankclip(1000000,70,32).killaudio().converttoyuy2().ShowFrameNumber().greyscale()
MonitorFilter(clip)
layer(clip,bc,"add",200,10,0)

Does not show any picture, but

Loadplugin ("avsmon.dll") 
clip=avisource("D:\SH0DAN\MPG\Ice Age.avi").converttoyuy2()
bc=blankclip(1000000,70,32).killaudio().converttoyuy2().ShowFrameNumber().greyscale()
layer(clip,bc,"add",200,10,0)
MonitorFilter(clip)

works ok.

At the moment I've no idea where the problem could be, but I'll try to fix it..

Best regards

No hurry - it already rocks! It would just be great to be able to preview intermediate stages of the filters.

This gives me all new perspectives on an Avisynth GUI. I should really try to do a design-proposal, if I had the time.

Another nice-to-have would be some info like resolution, colorspace, framerate, samplerate, sample depth, channels.

Also a slide for "second-offset" for audio could be useful, especially with the compressed audio support, which has huge sync-problems when skipping in VBR mp3-material.

... I could go on - you really shouldn't listen to me!

I think that filter rocks, too! I'm reencoding the matrix with it, just to see it work
(Ok, I'm using more aggressive convolution3d settings than in my last test, too ).

I noticed that if you search backwards, the image doesn't get updated... only if you advance above the point where you've already been. Bug or feature?

Best regards,

and thanks for this nice dll

Maybe silly question, but how do you get the GUI to show up?
(or doesn't it work on win98).

[sh0dan]

... it just shows up (XP here)

[johann.Langhofer]

thanks for all the suggestions, I'll see what I can do...

for the actual problem:
Loadplugin ("avsmon.dll")
clip=avisource("D:\SH0DAN\MPG\Ice Age.avi").converttoyuy2()
bc=blankclip(1000000,70,32).killaudio().converttoyuy2().ShowFrameNumber().greyscale()
MonitorFilter(clip)
layer(clip,bc,"add",200,10,0)

I think although I'm not so very familar with scripting the MonitorFilter is an I/O filter that means you must (re)assign the variable you use for the clip. I've tested following versions without problems:

version 1:
clip=avisource("D:\SH0DAN\MPG\Ice Age.avi").converttoyuy2().MonitorFiler
bc=blankclip(1000000,70,32).killaudio().converttoyuy2().ShowFrameNumber().greyscale()
layer(clip,bc,"add",200,10,0)

version 2:
clip=avisource("D:\SH0DAN\MPG\Ice Age.avi").converttoyuy2()
bc=blankclip(1000000,70,32).killaudio().converttoyuy2().ShowFrameNumber().greyscale()
clip=MonitorFilter(clip)
layer(clip,bc,"add",200,10,0)

version 3:
clip=avisource("D:\SH0DAN\MPG\Ice Age.avi").converttoyuy2()
bc=blankclip(1000000,70,32).killaudio().converttoyuy2().ShowFrameNumber().greyscale()
MonitorFilter(clip)
layer(last,bc,"add",200,10,0)

Well, i think its quite logical it shows no picture, as in sh0dans script its kinda a dead end. I imagine avisynth to be operated-by-draw-at-the-end-of-the-chain, and in that example nothing draws at the MonitorFilter. (Well, this is prolly what johann meant by stating its an i/o filter)

Maybe the wrong thread to ask that, but since you mentioned it here, what convolution3d settings are you trying with Matrix? (I'm also considering to test convolution3d again, using MPEG quantizers and no lumi in both passes, maybe sharp bicubic, with Fight Club aiming for 1CD.)

thanks and best regards ,

Very cool !!! Thanks !! Avisynth only needed a preview to be perfect

[johann.Langhofer]

thx,
an extended version is now ready for testing...

- more statistics
- histogram switch (works for yuy2 only)

[theReal]

one question: what is the audio delay switch for?

[soulfx]

Sw337! This is really cool, awesome work johann.Langhofer.

The Histogram is a nice addition, it seems hard to read, but that's the way AviSynth's default histogram is.

One concern I had/have is effects of this monitor on framerate. I did some tests and what I can tell there really isn't any affect on framerate. Yay.

Peace,

Well, what is the verdict on Win98? At least two of us don't get any GUI. Are you blowing off Win98 users?

[johann.Langhofer]

To Neuron2: It's not the intention to blow off win98 users

If you can't get any GUI, the reason could be that I've used an api (CreateThread) on which the last argument must not be NULL for Win95/98/Me, but on NT/2000/XP it can be (just found from professor Google).
Sorry, I'll fix that as soon as possible, unfortenatly I'm at work now, so the earliest time to fix is the coming weekend.

To soulfx: I can't believe about the framerate, I've also done tests and was satisfied. The framerate is determined by counting the GetFrame()-calls inbetween a second measured with the multimedia-timer ??!

Best regards,
Johann Langhofer

@Johann

Thank you. We will look forward to the Win98 compatible version!

Nice move, Defiler. Make enemies of the people that help you.

[vidiot]

Just wanted to say:

Glad I´m not the last WIN98SE User in the world...

And I´m sure: Less Problems (except Fat32) and more power with the same system than NT or ME or...
(...more bang for the buck...)

BTW: for the price of a nice Win XP Version I could easily buy an DVD Burner - is that an option?

Please do not hijack this valuable thread with off-topic trolls. Otherwise, I'll have to resort to sanctions. Thank you.
