How do I get a map of functions from a plugin in api4?

Code:
VSMap * FunctionsMap = VSAPI->getFunctions(Plugin);

Use getNextPluginFunction(plugin, nullptr)
Then pass the returned pointer to the function until it returns null. That means you've enumerated all plugins.

Like this? Do I need to free the function every loop before getting a new one?

Code:
VSPluginFunction * function = VSAPI->getNextPluginFunction(nullptr, Plugin);
        
while (function != nullptr) {
    # do stuff with function
    function = VSAPI->getNextPluginFunction(nullptr, Plugin);
}

Correct, you don't have to free anything.

What does the argument string returned by "vsapi->getPluginFunctionArguments(function)" look like? I didn't see any example in the api

How do I get the videoFormat name and uses it in one line like in api3?

Code:
myFunction(videoInfo->format.name);

One line?
Code:
char name[32]; vsapi->getVideoFormatName(&videoInfo.format, name); myFunction(name);
But more seriously, use a lambda or something if you need it many times in the same function.

What do i have outdated? Older R51 portable is working.
Do I need Visual Studio 2019 for portable setup?
Install the most recent vs2019 runtime manually.

This is another use case in api3:
Code:
infoString.replace("%format%", videoInfo->format.name);

core.add_cache is removed (although remains in the doc). May I know about a replacement for it?

Cache insertion is now handled by the core so there's no direct replacement. If you want to change the automatic decision to add a lot of caching on your output simply use the SeVideoCache/SetAudioCache functions.

Thanks. Also I see all the arguments are required in these functions. Is it as intended?

No, they should obviously be optional

Code:
>>> import vapoursynth as vs
>>> core = vs.core
>>> clip = core.std.BlankClip(width=1921, height=1081, format=vs.RGB48)
>>> frame = clip.get_frame(2)
>>> frame[0] == frame[2]
True
>>> frame[0] == frame[1]
True
>>> frame = clip.get_frame(22)
>>> frame[0]
<memory at 0x0000021EE196B930>
>>> frame[1]
<memory at 0x0000021EE196B860>
>>> frame[2]
<memory at 0x0000021EE196B930>
>>>
Is it as intended in R55-RC1?

Yes, it's how you access plane data now

RC2 posted. Changes:
  • Reworked vsscript api to restore api3 functionality
  • AVFS fixes (packed RGB in Avisynth scripts)
  • Uses new and faster libp2p for packing
  • Removed lots of Python functions that have been deprecated since at least R51
  • API4 headers actually included in installer

Things you can do to help:
  • Update the __all__ tag in vapoursynth.pyx with all relevant symbols
  • Create vsscript4.h.rst and vshelper4.h.rst (these are simple and work 99% like the api3 counterparts)
  • Review pythonreference.rst (mostly updated by me already but probably missing some functions)
  • Review all other documentation.

The VSVideoFormat argument of isSameVideoPresetFormat() is missing the "constant" declaration?

Correct. Will be fixed.

Yes, now alt_output is an optional argument to set_output(). Makes more sense that way.
