  nvenc: allow setting the number of slices
  nvenc: De-compensate aspect ratio compensation of DVD-like content.
  nvenc: list the major contributors in the copyright header
  configure: Don't require nonfree for nvenc
  nvenc: drop the hard dependency on CUDA
  nvenc: only support HW frames when CUDA is enabled
  nvenc: write the VUI signal properties for HEVC
  nvenc: only write the VUI signal type fields if they are set
  nvenc: Generate bufferingPeriod/pictureTiming SEI
  nvenc: Delay frame output to increase encoding speed
  nvenc: add support for lossless encoding
  nvenc: Generate AUD NAL units for better compatiblity
  nvenc: fix the rc option definitions

All these commits are noop as requested by Timo Rothenpieler.

<BtbN> andrey_turkin, ubitux, yeah, I like the current state of nvenc in
ffmpeg, I think most remaining differences should be merged on the libav
side of things. At least I'm not aware of anything that's missing in
ffmpeg.

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 a mean to alter decoded Audio and Video through chain of 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.
  • ffserver is a multimedia streaming server for live broadcasts.
  • 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.

Examples

Coding examples are available in the doc/examples directory.
