running build-plugins.sh, building

• fms2000 failed
  
• mvtoolssf failed, and can be removed since it's Windows only
  

so it would be cool if you could look into fms2000

Good news: I managed to get vspipe working (the vspipe location changed from vapoursynth/bin/vspipe to vapoursynth/vspipe which caused a few problems).

Still working on vsViewer to get it working.

this is driving me nuts,..
1st I noticed that vsViewer/vsEdit by default tries to load 'vapoursynth-script', but there only is 'libvapoursynth-script' in the vapoursynth/lib-folder.
2nd after changing the code to look for libvapoursynth-script inside ~/opt/vapoursynth/lib and the file (/home/selur/opt/vapoursynth/lib/libvapoursynth-script.so) exists, but loading the library still fails,.. :/
will look more into it after some sleep

Problem seems to be
/home/selur/opt/vapoursynth/lib/libvapoursynth-script.so is a symlink to libvapoursynth-script.so.0, but libvapoursynth-script.so.0 doesn't exist!
-> seems to be a problem with the compilation/deployment of Vapoursynth

[Selur]

modifying the .deploy-vapoursynth.sh
by changing

mv -f bin/*.so lib/vapoursynth/

into

mv -f bin/*.so* lib/vapoursynth/

does fix the symlink from
/home/selur/opt/vapoursynth/lib/libvapoursynth-script.so to libvapoursynth-script.so.0
but loading
/home/selur/opt/vapoursynth/lib/libvapoursynth-script.so
still fails.
As aside note: needed to adjust the 'install-vs.sh' to use "g++ -std=c++11" instead of gcc and g++ in the compile vspipe on Ubuntu 16.04.
here's what I changed in the deploy-vapoursynth.sh

to modify the vsfilters_env.sh and use debug2-branch of vsViewer to get some debug info,...
sadly all this didn't really help with the loading.
update: small correction the initialization of the libraries did work, bug now it fails at 'vssInit' which is the function pointer to Vapoursynths 'vsscript_init'.

vsscript_init

int vsscript_init()

Initialises the available scripting interfaces.

Returns the number of times vsscript_init() has been called so far, including this call, or 0 in case of failure. This function will only fail if the VapourSynth installation is broken in some way.

see: http://www.vapoursynth.com/doc/api/vsscr...cript-init
-> :/

[Selur]

Okay, until I figure this out R47 breaks vsViewer (and vsedit).
-> will look at restricting Vapoursynth to R46 tomorrow

Cu Selur

[Selur]

Think I figured out how to adjust vsViewer to be Vapoursynth R46 compatible.
-> hopefully this fixes the Vapoursynth problem I had (will report back)

Cu Selur

[Selur]

Nope there's still a problem with vapoursynth (neither vspipe nor vsviewer work; still having problems initializing vsscript).
(aside from ffms2k not building)
