Vapoursynth

[BabaG]

thanks again.

the example for ffms2 suggests using autogen.sh, which i did use in setting up ffms2. however, lsmash does not seem to have that. i do see that there is an example for ffms2 in which meson is used. i find a file, meson.build, in the L-SMASH-Works/VapourSynth directory so i cd'ed into that and tried following the steps in the guide under 'meson method.'

the first step there is:

meson build/

which returned this:

sounds like i have to figure out updating libavcodec? cmake?

thanks,

Seems like the latest LSMASHSource is looking for a newer version of LibAV than what your OS has in packages. You have two options, either compile FFmpeg yourself, or just use the version of LSMASHSource that I linked before instead of the updated one.

second option sounds more my speed. you mean the link from post #4334 to L-SMASH-Works?

edit:
just tried that and got the same error so i guess i'm unsure of what 'linked before' refers to.

Just compile FFmpeg then, it's pretty simple.

[BabaG]

i really don't want to get into that. i have too much else that's dependent on it and all working fine. i really don't want to change it. getting the idea that vapoursynth is software better suited for rolling release distribution rather than lts one like i use. very disappointing. i really used to like avisynth and was hoping to get back into it in a modern context. i'm no admin or programmer, though. and haven't used windows for a few years either.

[l33tmeatwad]

You could just use ffms2.

[BabaG]

same error in vsedit:

Failed to evaluate the script:
Python exception: No attribute with the name ffms2 exists. Did you mistype a plugin namespace?

plugin does seem to be in the right place:

file:///usr/local/lib/vapoursynth/libffms2.so

[Yomiko]

In some systems /usr/local/lib is not a part of LD paths by default. Is it your case?

[BabaG]

sorry, LD?

[LigH]

Library directories for the compiler/linker workflow (see e.g. $LD_LIBRARY_PATH).

[l33tmeatwad]

Question, does Kubuntu use /usr/lib64? That could be the root of a lot of this confusion.

[BabaG]

there is a /usr/lib64 directory. nothing much in it. two shared libraries that don't seem vapoursynth related.

file:///usr/lib64/ld-linux-x86-64.so.2
file:///usr/lib64/libDaVinciPanelAPI.so

thanks,
babag

[l33tmeatwad]

You really need to just start troubleshooting things like trying to manually load plugins and such. VapourSynth either isn't looking in the /usr/local/lib/vapoursynth directory or ffms2 for some reason can't find it's dependencies.

For all the people concerned with antivirus alerts.
Just upload the binaries here:

Take Kaspersky as the most reliable.
Don't trust Avast or Norton. They're notorious for false positives.

[ChaosKing]

Norton just bought Avast for 8 billion!

I want to invoke a few filters in order programmatically, I want to reuse the VSMap that was returned from the invoke and the VSNodeRef.

VSMap * pResultMap = nullptr;

pResultMap = m_cpVSAPI->invoke(firstPlugin, filterName, pArgumentMap);
m_cpVSAPI->freeNode(pProcessingNode);
m_cpVSAPI->clearMap(pArgumentMap);

pProcessingNode = m_cpVSAPI->propGetNode(pResultMap, "clip", 0, nullptr);
m_cpVSAPI->freeMap(pResultMap);
pResultMap = nullptr;

// second filter
VSPlugin * secondPlugin = m_cpVSAPI->getPluginById(
                        "com.vapoursynth.std", m_pCore);            
m_cpVSAPI->propSetNode(pArgumentMap, "clip", pProcessingNode, paReplace);

Will the `freeMap(pResultMap)` also killed my `pProcessingNode` so it won't get passed to the second filter?

No, propGetNode() increases the reference count.

Thanks. Also do I even need the `pResultMap = nullptr;` after freeing it?

No. That's obviously pointless.

[Selur]

Does anyone have a working RemoveDirtMC script for Vapoursynth ?
The one from https://forum.doom9.org/showpost.php...99&postcount=2 is using a variable called 'quad' which isn't defined anywhere.
