Lynne c982376076 vulkan: extend ff_vk_shader_rep_fmt to be useful for bitexactness The original either reported 8 or 16-bit conversion from the original, rather than being able to return the actual original. This makes it usable in a situation where preserving exactness is required.		2024-10-11 23:54:18 +02:00

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.
