Question
How to use Premiere's legacy callback suites with After Effect style plugins ?
TL;DR : I can't find how to acquire piSuite since I can't find the string indentifier, neither how to call the getCurrentPos function.
Note : I am aware that this issue is related to the Premiere Pro C++ SDK, but I posted this message here since most of my plugin uses the After Effect C++ SDK.
Hi !
I am currently making a Premiere Pro plugin, and I wanted to use the legacy callbacks (piSuites) described here, and more specifically, timelineFuncs's getCurrentPos function.
My issue
When I try to use the piSuites, I can't find any string indentifier within the SDK to acquire the suite...
Here it was I call a suite's string identifier :
#define kPFUtilitySuite "PF Utility Suite"
// ...
#define kPFUtilitySuiteVersion13 13
#define kPFUtilitySuiteVersion kPFUtilitySuiteVersion13I might have missed it in the Premiere or After documentations, but there is no code sample or any indication on how to initialize either of the following structures that stores a pointer to the functions I want to use :
- PlugTimelineFuncsPtr
- EffectHandle
- piSuitesPtr
I have tried to initialize each of these structures without and with a null pointer, but I get a memory access violation.
My guess from the debug logs is that the pointer never gets the actual structure and remains null, although I am new to after effect and premiere pro plugins so I am not certain on how memory allocation works inside the plugins.
Configuration
I am using After Effect's skeleton project, and I have included the Premiere Pro SDK within my project.
What works
I have written a few lines of code to check if what I wanted to do was possible. Since I need the PrTimelineID timelineData, I used the PF_UtilitySuite13 suite. The following code builds and runs well, and I could see the timelineId in my debug console :
static PF_Err
Render (
PF_InData *in_data,
PF_OutData *out_data,
PF_ParamDef *params[],
PF_LayerDef *output )
{
// ...
PrTimelineID outTimelineID;
PF_UtilitySuite13* utilitySuite = nullptr;
int currentFrame;
in_data->pica_basicP->AcquireSuite(kPFUtilitySuite, 1, (const void**)&utilitySuite);
utilitySuite->GetContainingTimelineID(in_data->effect_ref, &outTimelineID);
in_data->pica_basicP->ReleaseSuite(kPFUtilitySuite, 1);
Logger::debug(
"Timeline ID : " + std::to_string(outTimelineID)
);
// ...
}The output was : [DEBUG] Timeline ID : 5346, so my conclusion was that the Premiere Pro SDK was well imported into my project.
What I understand
I understand that a suite must have a string identifier as well as a version number in order to acquire it, but as I explained earlier, I can't find the piSuite's string identifier.
My question is How to use the piSuite and/or how the function getCurrentPos can be used ?
Thank for your help !
