Andreas Rheinhardt 3e19e5062c avcodec/decode: Move is_open check to avcodec_receive_frame() 
It also applies to scenarios where ff_encode_receive_frame()
is used. Also remove the redundant av_codec_is_decoder().

  • 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.
