avcodec/cuviddec: honor application-selected software output 
The CUARRAY output option made the decoder override a software format
selected by get_format() with CUDA. This broke ordinary CUVID decoding
to software consumers.

Default output_format to auto and only override get_format() when the
user explicitly requests cuda/cuarray or enables zero_copy. Keep the
internal frames context in the corresponding hardware format and reject
opaque/non-opaque transitions during decoder reinitialization.

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
