sequence_data gateway from popup_dialog to render

[crazylafo]

Hi everyone.

I'm working on a plugin wich use popupdialog in order to call a script UI. The function works fine.

But I try to send some strings results to the Render function. I tried by using sequence_data (based on pathMaster exemple and reduxFX exemple ) but when I look step by step the execution, the sequence_data get the good value in popudialog function but get back to the initial value before render call....

The popupdialog has the outFlag "PF_OutFlag_FORCE_RERENDER".

Is there an other way to comunicate between the PopupDialog and the Render ?

The code is a bit long with the sequence flattening so so I share the github link :: AE_tl_math/tl_math.cpp at master · crazylafo/AE_tl_math · GitHub

thanks for your help.

off the top of my head:

1. leave the message in global_data, along with an effect identifier (comp

itemID, layerID, and effect index). the render thread can then see if it's

own matching identifier has a message waiting for it.

2. write the data to an arb param. that gets synchronized immediately and

reliably between threads.

thank you Shachar. the global data is a good deal. (but the arb param, it's is looking a bit  complex and it cannot be modify in DO_DIALOG thread). Thanks for your solution.

[shachar carmi]

the arb param can be changed during DO_DIALOG. just use SetStreamValue().

another advantage, is when using an arb param the user can undo and redo

the operation.

but you know your needs better, so pick the solution you're most

comfortable with.

wha SetStreamValue can work on arb and not only "classical" params ? thanks for this trick

[shachar carmi]

it's a secret! don't tell anyone... 😄

[crazylafo]

  I'll may change my mind with arb... For a simple gateway, does an  arb needs the list of handles with scan/interpolate and compare functions ?

[shachar carmi]

you can always return the original value instead of creating an actual

interpolation. as for scan and print, i never implemented them, and it

never caused an issue for me.

take a look at the ColorGrid sample project. it's pretty easy taking that

implementation of an arb param and change it for your needs. whatever is

required is already implemented there.

Thanks again I'll take a look on it.

[crazylafo]

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. But if I dispose the streamValue  I get a "magic error" . However, the effectRef and the streamH dispose correctly.

the function :

static PF_Err

AEGP_GetParamStreamValue(PF_InData  *in_data,

  PF_OutData  *out_data,

  AEGP_PluginID   PlugId,

  PF_ParamIndex  param_index,

  PF_Handle  *arbH

)

{

  PF_Err err = PF_Err_NONE,

  err2 = PF_Err_NONE;

  AEGP_LayerH  layerH;

  AEGP_StreamRefH effect_streamH = NULL;

  AEGP_EffectRefH   thisEffect_refH = NULL;

  AEGP_StreamValue2  val;

  AEGP_StreamValue2  *sample_valP = &val;

  const A_Time currT = { 0,100 };

  AEFX_SuiteScoper<AEGP_PFInterfaceSuite1> PFInterfaceSuite = AEFX_SuiteScoper<AEGP_PFInterfaceSuite1>(in_data,

  kAEGPPFInterfaceSuite,

  kAEGPPFInterfaceSuiteVersion1,

  out_data);

  AEFX_SuiteScoper<AEGP_LayerSuite8> layerSuite = AEFX_SuiteScoper<AEGP_LayerSuite8>(in_data,

  kAEGPLayerSuite,

  kAEGPLayerSuiteVersion8,

  out_data);

  AEFX_SuiteScoper<AEGP_StreamSuite4> StreamSuite = AEFX_SuiteScoper<AEGP_StreamSuite4>(in_data,

  kAEGPStreamSuite,

  kAEGPStreamSuiteVersion4,

  out_data);

  AEFX_SuiteScoper<AEGP_EffectSuite4> EffectSuite = AEFX_SuiteScoper<AEGP_EffectSuite4>(in_data,

  kAEGPEffectSuite,

  kAEGPEffectSuiteVersion4,

  out_data);

  PFInterfaceSuite->AEGP_GetEffectLayer(in_data->effect_ref, &layerH);

  PFInterfaceSuite->AEGP_GetNewEffectForEffect(PlugId, in_data->effect_ref, &thisEffect_refH);

  StreamSuite->AEGP_GetNewEffectStreamByIndex(PlugId, thisEffect_refH, param_index, &effect_streamH);

  StreamSuite->AEGP_GetNewStreamValue(PlugId, effect_streamH, AEGP_LTimeMode_LayerTime, &currT, FALSE, sample_valP);

  *arbH = reinterpret_cast<PF_Handle>(val.val.arbH);

  if (thisEffect_refH) {

  ERR2(EffectSuite->AEGP_DisposeEffect(thisEffect_refH));

  }

  if (effect_streamH) {

  ERR2(StreamSuite->AEGP_DisposeStream(effect_streamH));

  }

  /*

  if (sample_valP) {

  ERR2(StreamSuite->AEGP_DisposeStreamValue(sample_valP));

  }*/

  return err;

}

i'm not entirely sure... perhaps you should dispose of the value before

disposing of the stream.

you(re right Thanks a lot
