lusoris bf0e831606 doc/encoders: add a section for the NVENC encoders
h264_nvenc, hevc_nvenc and av1_nvenc had no entry in encoders.texi.
Document them in one section: hardware input and devices, the generic
options they map, the options common to all three (presets and tuning,
rate control, lookahead, AQ and B-frames, SEI and side data), and the
options specific to each codec.

Option names, named values, ranges and defaults follow the AVOption
tables in nvenc_h264.c, nvenc_hevc.c and nvenc_av1.c, checked against
ffmpeg -h encoder=<name> from a build against nv-codec-headers 13.1.
Options that depend on the SDK version state the version they need.

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.
