Writer (DX11.Texture 2d) not writing

[sunep]

I can’t get Writer (DX11.Texture 2d) to actually write a texture to a png or bmp file.

TTY spits this out when I try to write a file:

00:04:35 ERR : SlimDX.Direct3D11.Direct3D11Exception in SlimDX: E_FAIL: An undetermined error occurred (-2147467259)

Stacktrace:

can you post a patch that demonstrates this?

Had the same problem when using Writer (DX11.Texture 2d) right after VideoIn (DX11 DShow). As a workaround, I used DrawFullScreen + TempTarget and then Writer. See attached.

Kind of found a solution, I use ChangeFormat (DX11.Texture 2d) to change the format to 8bit.

I do think that it is a clumsy way of not letting you know what is wrong.

Anyway, this patch demonstrate the problem: DX11-writer-test.v4p (6.5 KB)

@sebescudie your patch doesn’t work here, I don’t have DrawFullScreen apparently, it’s red here

@sunep You need last DX11 pack :)
