EMP question

[_Q_Iqbal_]

Hello,

I have the following questions. Any help will be appreciated.

(1) For the EMP (External Monitor Preview) plugin, for a given composition how many times is the hooksP->blit_hook_func called when I change the timeline pointer. I have noticed that the number varies and I could not figure out the pattern; may be it has to do with the in/out points of layers and which layers are visible at a give point? Also, is it providing me the composition buffer or layer buffer?

(2) AE_IO.h defines the following:

AEIO_InputDepth_64 = 64,
AEIO_InputDepth_96 = 96,
AEIO_InputDepth_128 = 128,
AEIO_InputDepth_GRAY_16 = -16,
AEIO_InputDepth_GRAY_32 = -32

where as AE_GeneralPlug.h stops at:

AEGP_FootageDepth_64 = 64
AE_GeneralPlug.h: AEGP_FootageDepth_GRAY_16 = -16

Shouldn't there be the AEGP_FootageDepth_96 and AEGP_FootageDepth_128, and AEGP_FootageDepth_GRAY_32 defined also? Not sure which one apply when?

Thanks again for any Help

EMP plug-ins are called whenever the buffer displaying the current composition is updated.

Your plug-in's entry point function gets called when AE launches; that might be a good time.
