Hey Darrin, et al.,
So I'm writing a plugin that is doing an analysis pass on a sequence. I do
this in response to a user clicking a UI button in our plug-in interface.
When I get CPU memory images using [FxTemporalImageAPI getBitmap]
everything works just fine.
However, if I try to get GPU texture, using [FxTemporalImageAPI
getInputTexture], then I can't get the bits because the current OpenGL
context is not set up. If I call [FxTexture textureID] and [FxTexture
getTextureCoords], etc. I get the proper values. Calling –bind or –enable
doesn't work either.
Darrin, is there a way I can successfully use GPU textures if I'm not in
–renderOutput? I presume I would need the OpenGL context and set the
current context to that, but that is not something I've been able to
successfully retrieve.
Pete
