James Almer 19085287b4 avutil/tests/aes_ctr: also check the encrypted buffer 
The test in its current form is just ensuring the plain text output is the same
as the plain text input, not bothering to check if anything was done with the
latter. av_aes_ctr_crypt() could be a simple memcpy under the hood and this
test would still succeed.

To check the integrity of the encrypted buffer, both the IV and the key need to
be fixed. As such, and in order to not remove the existing randomization of the
input IV, do two runs, one with random initialization data, and one with static
data.

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.
