[vlc-devel] [PATCH 00/32] Road to push video context (v4)

[Steve Lhomme]

Compared to the previous patchset:

- fix issues with --dec-dev=none
- fix issues when probing VAs multiple times

The way the vout is tested/created when a decoder device is created and the
display module is created conditionally needs a bit more work. The whole
monolothic decoder_UpdateFormat split in 2 calls that are indenpendant needs
to check the video context has not changed to create a new vout/display or not.
This is easier now that we push a usable video context. In the interim stages
of this patchset it's fragile (but it works).

Steve Lhomme (32):
  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
  video_output: 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()
  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 output: request the vout with a video context
