avisynth scripts as avidemux2 video filter in Linux

[fahr]

Hello!

I'm write external video filter for avidemux2 for Linux. This filter is used for load avisynth script as native avidemux2 video filter. Filter supports external binary Windows dll in avisynth script (thanks wine), several AvsFilter instance with different avisynth script and many other features.

Filter, description, sources, usage tips and tutorial here:

Thanks,

uoho!!

great work!

Cool. But, what if any advantage over the included and built in avsproxy that already comes with Avidemux?

1. You use native avidemux2 parser for videofiles instead ffdshow/xvid/other windows codecs/container parser under wine
2. You use avisynth script in depth of videofilters of avidemux2 (after equalizer or other prefiltering).
3. You can use several scripts in any point between avidemux2 filters. Each script work independently.
4. Do not need restart avidemux2 if you change avisynth script, simple store script with other filename and change avsfilter scriptname parameter in avidemux2 filter list.
5. You can use several avidemux2 with various avisynth scripts for video processing simultaneously.
6. Avidemux2 sheduler(joblist) work normally (project file contain avsfilter parameters), but if you use avsproxy, we cannot work with differents input video and need to start avsproxy before start avidemux2.
7. To work with video, we could open it with avidemux2 and add avisynth script (with avsfilter) at any stage of video processing. If you use avsproxy, we should be open video with proxy before edit or any other stage of video processing.

If all video processing work only in avisynth script, then no advantages over avsproxy.

Your instructions say to patch sources using "patch.prefs.in", but I don't see that in the download. Did you forget to add it?

I went on ahead and just removed the -DPREFSINCHANGE and did it that way. It doesn't work though. I go to add AvsFilter to the Active Filters list, fill in the information and click OK. It never gets added.

This is what I get in the console when attempting to add:

Your script is not contain string
LoadPlugin ("pipe_source.dll")
OR
pipe_source.dll is not find inside call LoadLibrary()

What path for pipe_source.dll?

Try store pipe_source.dll to script directory.

[defaulk9]

That put me on the right track. My path to avsload.exe had spaces in it, so I had to quote it. Just the opposite with the path to the script. That seemed to want an unquoted path.

Thanks for the assistance. And thanks for the patch too. I'll try it out.

One other question: is there a way to reload the script without having to restart avidemux? I seem to have to restart every time I change it in order for the changes to take effect.

Thanks again.

You may save script with other filename and change filename in filter properties. No need to restart, but in future, I planned some improvement for this happened. Unfortunately, reload script after each filterobject creation get many processing time.

What binary filters(dll's) you use with avsfilter?

I thought about that. The only solution I can think of is to first test if a significant amount of time has passed since the processing of the last frame (I'm unfamiliar with avidemux's filter API, so that may be off base), and if the time interval is large enough, do a check against the script's file date, and finally if that has changed, reload.

I don't have a set list. Currently I'm doing some film restoration, so I'm using deflicker and a conditional temporal median filter and trying out some others as well. I'm experimenting with different plugins and approaches here, so that's why the reloading helps.

I implemented script change feat:
============================================
In this version, avsfilter checked timestamp of script. If timestamp of script change, avsfilter reload fresh script to avisynth. For use this feature, you can remove avsfilter from videofilter list, change script and reload avsfilter again to videofilter list with the same script name. No need to rename script and reload them with changed filename.
=============================================

Fixed serious bug in the time of encode frames span(A - B in avidemux2). At the moment of processing frame with number > (B - A), frame replace by frame 0. All following frames also replace by frame 0. This is no happens, if you encode whole input video.

05 March 2009
Stupid (but serious) bug was fixed. These bug inserted by 04 March of 2009. Under processing video with complex binary avisynth filter (like fft3dfilter), several frames need to render one frame. This bug (before it fixed) breaks normal frame sequence. Version 0.4a is out.

Update linux/wine sources

http://avsfilter.berlios.de/src/filt...3.2009.tar.bz2

and wine binaries (who not compile it from sources)

http://avsfilter.berlios.de/src/avsl...binary.tar.bz2

18 Apr 2009

Update compile and build docs, add FAQ for use .avs with VDF-filters from Donald's Graft VirtualDub. Add example script what is load external VDF-filter (_VD_Logo) in .avs script for use with avidemix2. Fix error with span start/end framenumber for preview mode. This error is show only in framenumber-specific filters (like ShowFrameNumber()). Update linux sources

[shevegen]

Can this link be added to avisynth homepage (the wiki)?

I think not everyone reads this forum here, although of course this forum is the biggest I know of

I think I am here since 6 years hehe

[Wilbert]

Can this link be added to avisynth homepage (the wiki)?

Yes of course. It would be nice if there would be a section about AviSynth & Wine and stuff like this. The problem is that i never have used Wine, so i'm not the most suitable person to write something about this. Could you volunteer to write such a section?

17 May 2009
Version is 0.5a. Fix other error with span start/end framenumber for encode and preview mode. Update linux sources
http://avsfilter.berlios.de/src/filt...5.2009.tar.bz2
and wine binaries

hello. is possible compiling this filter for QT avidemux version?

this filter only appears in GTK version, no in QT version


thanks

Hello!

This filter not intended for avidemux GTK version only, but this happen is not checked. You can compile and it is difficult, write me (fahr at inbox dot ru).

In avsfilter no any GTK parts, no interface part. In fact, avsfilter is skeleton of avidemux video filter (with some code for start loader in wine environment, pipe read/write and other smallest helpers/routines).

Bye

[sl1pkn07]

hi!

the plugins not compile in the latest Avidemux 2.5

greetings
