Sam James 2f24f10d9c libavcodec: fix -Wint-conversion in vulkan 
FIx warnings (soon to be errors in GCC 14, already so in Clang 15):
```
src/libavcodec/vulkan_av1.c: In function ‘vk_av1_create_params’:
src/libavcodec/vulkan_av1.c:183:43: error: initialization of ‘long long unsigned int’ from ‘void *’ makes integer from pointer without a cast [-Wint-conversion]
  183 |         .videoSessionParametersTemplate = NULL,
      |                                           ^~~~
src/libavcodec/vulkan_av1.c:183:43: note: (near initialization for ‘(anonymous).videoSessionParametersTemplate’)
```

Use Vulkan's VK_NULL_HANDLE instead of bare NULL.

Fix Trac ticket #10724.

Was reported downstream in Gentoo at https://bugs.gentoo.org/919067.

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.
