[FFmpeg-devel] [PATCH v4 00/16] Add a Vulkan compute based FFv1 hwaccel

[Lynne]

This series of commits adds a fully compliant version 3 and 4 hardware
accelerator code for FFv1 written in Vulkan.

Changes from the previous version:
 - Use the exported host_map code in hwcontext_vulkan.c
 - Add a buffer_ref argument to FFHWAccel.start_frame
 - Various optimizations in the shader code

Lynne (16):
  pixfmt: add AV_PIX_FMT_GBRAP32
  vulkan: rename ff_vk_set_descriptor_image to ff_vk_shader_update_img
  vulkan: add ff_vk_create_imageview
  vulkan: copy host-mapping buffer code from hwcontext
  hwcontext_vulkan: use the common host map function to map frame data
  vulkan: workaround BGR storage image undefined behaviour
  vulkan_decode: support software-defined decoders
  vulkan_decode: support multiple image views
  vulkan_decode: adjust number of async contexts created
  ffv1enc_vulkan: refactor shaders slightly to support sharing
  vulkan: unify handling of BGR and simplify ffv1_rct
  vulkan: add ff_vk_exec_add_dep_wait_sem()
  vulkan: add support for AV_PIX_FMT_GBRAP32
  ffv1dec: add support for hwaccels
  FFHWAccel: add buffer_ref argument to start_frame
  ffv1: add a Vulkan-based decoder
