Niklas Haas c0b93c4f8b avfilter/vf_libplacebo: support all supported pixfmts
This is done only to the inputs, not the outputs, because we always
output vulkan hwframes.

Doing so also requires keeping track of backing textures for non-hwdec
formats, but is otherwise a mostly straightforward change to the format
query function. Special care needs to be taken to avoid crashing on
older libplacebo due to AV_PIX_FMT_RGBF32LE et al.

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
