vulkan_encode: set the quality level in session parameters 
While running this command

./ffmpeg_g -loglevel debug -hwaccel vulkan -init_hw_device vulkan=vk:0,debug=1 -hwaccel_output_format vulkan -i input.y4m -vf 'format=nv12,hwupload' -c:v h264_vulkan -quality 2 output.mp4 -y

It hit this validation error:

Validation Error: [ VUID-vkCmdEncodeVideoKHR-None-08318 ] Object 0: handle =
0x8f000000008f, type = VK_OBJECT_TYPE_VIDEO_SESSION_KHR; Object 1: handle =
0xfd00000000fd, type = VK_OBJECT_TYPE_VIDEO_SESSION_PARAMETERS_KHR;
| MessageID = 0x5dc3dd39
| vkCmdEncodeVideoKHR(): The currently configured encode quality level (2) for
VkVideoSessionKHR 0x8f000000008f[] does not match the encode quality level (0)
VkVideoSessionParametersKHR 0xfd00000000fd[] was created with. The Vulkan spec
states: The bound video session parameters object must have been created with
the currently set video encode quality level for the bound video session at the
time the command is executed on the
device (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-vkCmdEncodeVideoKHR-None-08318)

This patch adds a new function helper for creating session parameters, which
also sets the quality level and it's called by the H.264 and H.265 Vulkan
encoders.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation

The offline documentation is available in the doc/ directory.

The online documentation is available in the main website and in the wiki.
