AEGP_GetNewKeyframeSpatialTangents returns incorrect data

Hi All,

I'm trying to read the in/out value of the animated mask stream.

I used the AEGP_GetNewKeyframeSpatialTangents function


AEGP_StreamValue2 tangIn_ = { }, tangOut_ = {  };

ERR(keyframeSuite4->AEGP_GetNewKeyframeSpatialTangents(pluginId, streamHandle, keFrameIndex, &tangIn_, &tangOut_));

After using the values, I'm trying to dispose the output values,

streamSuite3->AEGP_DisposeStreamValue(&tangIn_)

streamSuite3->AEGP_DisposeStreamValue(&tangOut_)

and that crashes the AE (2014).

Any ideas why AEGP_GetNewKeyframeSpatialTangents return incorrect streamH value in the AEGP_StreamValue2?

Hi kotuk81,

it crashes because SpatialTangents are used for Position streams, not masks.

I think what you're trying to get is 'AEGP_MaskVertex' values. In this vertex, you'll find the vertex itself (x and y) AND the tangents (in x, in y, out x out y).

You can have a look at this thread for details:

Fail to add new mask vertex

The thread is about 'setting' the mask vertices, but you'll easily figure how to 'read' them.

Hope it helps,

François

Hi François,

Yes, you're right, I was using the wrong functions.

What I was seeking for is the TemporalEase values and I had no problems to pull those from AE)
