[vlc-devel] [PATCH 00/42] Road to push video context (v5)

[Steve Lhomme]

Compared to the previous patchset:
- more patches to send a real video context with useful data for D3D (external
  rendering requires that the video device is the same between the host app,
  the decoder and the display module)
- VAAPI/VDPAU have not been updated with data in the video context, not sure
  they need extra data that are not in the video device
- rework some vout calls not to rely on stored data that will not be stored 
  anymore in push
- fix a bug where the stored decoder device in the decoder was missing a reference
  (it's only breaking bisect because that storage is going away a few patches later)
- only pass the vout thread and video format to get the decoder device, the rest
  of the display configuration data (like DPB size) are passed when getting the
  display module. So now there are 2 different configuration structure: one to
  get a decoder device (vout_device_configuration_t), one to get a display
  module (vout_configuration_t).
- rename all "decoder device" hold functions to get functions, the values are
  returned directly rather than filling a pointer of pointer.

Steve Lhomme (38):
  video_output: pass the video format to vout_SizeWindow()
  video_output: set the pose outside of VoutGetDisplayCfg
  opengl: pass the video context rather than the decoder device
  decoder: use a separate function to clean the display video format
  decoder: move the display creation in a separate function
  decoder: clean CreateVoutIfNeeded
  video_output: split vout_Request to have a function to enable the vout
    window
  video_output: add vout_GetDevice to get the vout decoder device on
    demand
  vout: request the display with a decoder device
  display: don't store the dummy context in the display anymore
  decoder: request decoder device when getting the vout
  input: resource: get the decoder device before calling vout_Request()
  decoder: split the decoder format update in 2 parts
  input: resource: split input_resource_GetVout()
  decoder: move the display creation in a separate function
  decoder: split the creation of the vout/decoder device and the display
    module
  video context: add a Create/Release function for the video context
  video context: make the video context structure private
  decoder: allow multiple calls to HoldDecoderDevice before calling
    UpdateFormat
  avcodec: get the decoder device before creating the VA
  avcodec: provide the vlc_decoder_device from the vout thread to the VA
    constructor
  d3d11va: use the decoder device to init the D3D11 device
  dxva2: use the decoder device to init the D3D9 device
  avcodec: vaapi: allocate output pictures locally
  vaapi: use the decoder device to get the VADisplay
  avcodec: do not use a picture from the display before creating the VA
  decoder: optionally pass a vlc_video_context in
    decoder_UpdateVideoOutput()
  decoder: remove locally stored decoder device
  nvdec: create a video context for the decoder
  avcodec: get the vlc_video_context created by the VA
  d3d11va: create a video context for the VA
  dxva2: create a video context for the VA
  vaapi: create a dummy video context
  vdpau: create a dummy video context
  video context: allow storing typed extra data in the video context
  dxva2: store the IDirect3DDevice9 in the video context
  d3d11va: store the ID3D11DeviceContext in the video context
  vout: request the vout with a video context
