Memory leak in Info (EX9.Texture) or in FromSharedTexture (DX11)?!?

hiho,
finally i also start messing around with that lovvvvely DX11-stuff…

currently lifting a quite heavy patch (4 videocams etc.) from DX9 to DX11.

i noticed a Memory leak within the module posted by joreg (have 6 instances in use…).

with level = 0 on the Info (EX9.Texture) the Shared Handle alternates each Frame (at least here).
Setting level to 1 after a few frames almost stops the leak; and hovering some output pins of the Info (EX9.Texture) seems to be finally very helpful…

your old kalle

p.s.: a modified version of the module is attached

DX9ToDX11 (DX11.Texture 2d).v4p (5.6 kB)

ai kalle,

the flickering of the sharedhandle comes from videotextures which are doublebuffered. so thats by design.

the Info node also has a Levels output. for videotextures that should be 1. is it? if so, changing the Level input really shouldn’t make any difference.

heyoreg,

from what i experience here the Level initially has to be 0.

if i just set Level Input to 1 i do not get anything what i would call a texture…

i confirm the Level Output being 1 but changing Level Input definetely makes a difference.
at least it does in my weighty patch.

and it definitely wants to leak Memory…

best regards
