Chris Spencer f0b1cab538 hwcontext_vulkan: always use create_pnext in vulkan_pool_alloc 
Currently, create_pnext is only used if an applicable external memory
extension is enabled. This will usually the case when used from the command
line, but may not be when the Vulkan context is created manually.

For images used in video decoding, create_pnext contains the video profile
list, which is mandatory.[1] This fixes a GPU crash when using RADV.

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.
