Ricardo Constantino d50b5d547f rtmpdh: Initialize gcrypt before using it 
Either disabling or init'ing secure memory is required after the use
of gcry_check_version. From a look at the functions rtmpdh uses, I
noticed none require the use of secure memory, so we disable it [1][2].

This resolves some errors returned by rtmpdh code with uninitialized
gcrypt, especifically:
Fatal: failed to create the RNG lock: Invalid argument
FATAL: failed to acquire the FSM lock in libgrypt: Invalid argument

Version "1.5.4" was arbitrarily chosen. An older version probably works
as well, but I couldn't compile older versions to test on my machine.

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.
