Andriy Gelman d4c46dc328 avcodec/movtextenc: fix writing to bytestream on BE arches 
Fixes fate-binsub-movtextenc on PPC64

Currently tags are written in reverse order on BE arches. This is fixed
by using MKBETAG() and AV_RB32() to be arch agnostics.

Also s->font_count is of type int. On BE arches with 32bit int,
count = AV_RB16(&s->font_count) will read two most significant bytes
instead of the least significant bytes. This is fixed by assigning
s->font_count to count first.

The final change is modifying the type of len. On BE arches
the most significant byte of the int was written instead of the least
significant byte.

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