Steven Liu 40597add98 avformat/hlsenc: write temp file for append single file by encryption mode 
fix ticket: 8783
Because in single file by encryption mode, it cannot get the last one
block of the file, it need ff_format_io_close for get full file size,
then hlsenc can get the total size of the encryption content,
so write the content into temp file first, and get the temp file content
append the temp file content into append to single file, then hlsenc can
get the correct file/content size and offset.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

  • 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.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
