[vlc-devel] [PATCH 0/5] Direct3D11 deinterlacing

[Steve Lhomme]

In Direct3D11 textures are "strongly" typed. They can only be bound on certain
parts of the pipelines at once but not all of them. So for example it's not
possible to have a texture to use with the decoder, in a VideoProcessor and
to be displayed.

To do GPU deinterlacing we need textures that go in/out of a VideoProcessor.
But since the textures cannot be the same as the decoder+shader ones, we need
to know what kind of texture we are creating. So I split the current 3 main
pools in the core into distinct pools to the vout. This is opt-in so other
vouts can continue to work as they used to.

The first part of the patch is to differentiate the 3 pools when the core
requests them. A new type for each of these 3 pools is introduced and passed
to the Pool() callback. The display pool requests 3 pictures (it may be 
2= DISPLAY_PICTURE_COUNT + 1 kept picture), the filter pool 4 pictures (3 for
filters and 1 for SPU) and the decoder pool at least dpb_size + 1 with a
minimum of 14 (20 -(4+1+1)).

The second part allows a vout to tell if it can display pictures coming from
the decoder pool. This may not always be the case in D3D11.

The next patch adds support for typed pools in D3D11, refining the binding and
CPU usage depending on the type of pool requested.

Then the D3D11 deinterlacer which uses the decoder pool on input and filter
pool on ouput.

Fixes #12855 for D3D11, in D3D9 there is no such binding restrictions so the
current pool can probably be used.

Steve Lhomme (5):
  [RFC] core: allow use different pool sources for different types
  [RFC] core: add a way for the vout to tell if it can display decoder
    pictures
  direct3d11: handle separate pools for decoder/display/filters
  d3d11_fmt: rename inputView to processorInput
  vout: win32: add a Direct3D11 deinterlacer
