Andreas Rheinhardt 47b1c0d0db avutil/hwcontext_vulkan: Improve type-safety 
The AVBuffer API uses uint8_t as base type for buffers
and therefore its free callbacks need to abide by this.
Therefore vulkan_frame_free() used an inappropriate signature
which caused casts whenever this function has been called
manually.

This commit changes this by making vulkan_frame_free()
use the proper type and a vulkan_frame_free_cb() that
is used as free callback for the AVBuffer API.

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
