Ok, so after tests, it seems that the solution using checkout_PARAM for layers in compute cache  is the best, if the plugin needs a result computed in previous frame. No overloaded memory, but layer parameters don't have access to applied effect, like the same layers loaded in smartfx ... View more

The CEP exports some files in a specific folder and then send the message to the plugin, in order to load it. CEP->create files ->send the message to plugin (check the checkbox) and then the plugin load and store the files. ... View more

i wanted to send some data from panel to CEP without user interaction on the plugin side. It works on AE but I understand that is not real UI interraction. For premiere I finally found a trick deselecting/reselecting the clip target, using script then it call updateparamUI but I can t change the value of some parameters. ... View more

After a lot of research there is no way in AE sdk (for now..). justintaylor is right, the only way is to execute script from plugin to call CEP and to sendData. (with AEGP_executescript) To catch data from cep to plugin I cheated creating an invisble checkbox called by CEP with global variable. If someone has a proper solution... ... View more

Is there an official  Vulcan implementation in c++ sdk ? For now I found a solution with the jsx script using aegp_executescript. The script call Vulcan to dispatch event  from plugin to plugin. From cep to plugin I use an invisible checkbox in plugin part to catch  message from cep. It s homemade but it works. ... View more

After some deep looking in documentation and exemples I still have problems with html<-->c++ communications in AE. -From plugin to cep I "cheated" using script find menucommandid() and executeCommand(). But is there a proper way to call a cep from a plugin ? -from cep to plugin how to send properly data using events and how to catch them in the plugin part ? I sow a exemple un redgiant coloristaIV. but it s commercial and so protected.  in this exemple each modifications in the cep GUI apply the values in live to the plugin effect, including in ARB data.... ...

Ha you maybe right..  Does the "Apply"  button close the script Window ?  I understood that the script was called from plugin, then does some stuff and send data to plugin when it's closed... If not sorry, I'm wrong. ... View more

it's maybe not themore appropriate way, but in a similar case I used a json solution. On the plugin side I include a json parser  lib  (evyrthing is in a header (like https://github.com/nlohmann/json  or some smaller lib). On  script I use jsonjs GitHub - douglascrockford/JSON-js: JSON in JavaScript  (thanks shachar in a previous thread). The script is called with userChangedParam. the data comes from the arb to json. the script part  send data  to json and the plugin parse the result  in order to  send it back to arb . my code is here if you want to have a look. (in the dialog.cpp file). ... View more

I sow this JSON-js/json2.js at master · douglascrockford/JSON-js · GitHub  and I think I have to add it in the script part. It's a bit strage, the script was tested on different systems, mac or windows. If I get the error 'JSON is undefined' and restart after effect, it works well again... But last question : is there a proper solution to call the cep engine  and to put a dialog window/ui  written in html/js  inside  a plugin  (not to put it in extension)  ? ... View more

In some exemples the lib uses std::thread. I did some test outside of AE and it works fine.But the paser function  itslef is not threadsafe.I've just  checkout  the readme. sorry I m discovering the dark side of the multithreading, I didn't t work around yet. UPDATE : forget it. I found the solution  with the external lib and know,  It's possible to use the Iterate generic function.   The first test seems to  look so faster... Tanks Shachar and Toby ...

In the CCU exemple every iterations happens in the same threads that's why the iteration with the dependencies works.      the structure looks like : PF_err Render      -checkout params      -Use a parser (from exptrk) to compile and return an expression Expr  (ask a lot of ressources so I've to call it only once)      -loop for(y < height)            loop for(x <width)                Expr returns value for each pixel If I set the expression in a pointer to send  the iterate_generic (or classical iteration function)  I get noisy result. I don't know why but it's impossible to split them. I'm looking around because as you said generic iteration is faster ... View more

ha I didn't use pointers for each pixel around but now it's looking clear. I still have a problem creating a function for iteration but it comes from an external dependencie. thanks again ... View more

You're right iterate generic get some result faster  in other projects. But in the current situation I've a problem. There is a classical iteration (like CCU) and inside the iteration there is an other iteration for each pixels (3*3 around. I tried to call the iterate generic on the 3*3part and the result is slower... ... View more

I'll do some test and tell you the result . Does Iterate_generic work only for 8 bits ? ... View more

thank you. Yes I do it on every Pixel but I 'can't use iterate_generic in this situation because I store and send the value to a  math parser during the iteration for each pixels.  During the test, If  I do a 3*3 matrix, it's not too low but higher matrices array is the best way to get error. So I will stay with this low number for now thanks a lot ... View more

thanks the ARB works fine also with undo group in my first tests. But I've a new strange error  with dispose stream. I'm wrote the function to get the stream value.
