Martin Storsjö e788ca05a7 hevcdec: Use LOCAL_ALIGNED_* for declaring local variables with alignment 
Not all compilers can do alignment larger than the normal stack alignment
for variables on the stack. In these cases, the LOCAL_ALIGNED_* macros
produce the workaround alignment wrapper consisting of a padded array
and a pointer variable.

This fixes the hevc fate tests on RVCT/ARMCC after adding IDCT assembly
that actually assumes/relies on this alignment.

  • 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.
  • libavresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • avconv is a command line toolbox to manipulate, convert and stream multimedia content.
  • avplay is a minimalistic multimedia player.
  • avprobe is a simple analisys tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
