Casey Smalley b98ee1a355 aarch64/hevc: Replace br return with ret 
This patch changes the return instruction in the tr_32x4 macro from
BR to RET.

Function returns should always use the RET instruction instead of BR,
to avoid interfering with branch prediction.

On devices that support BTI, this is observeable as a landing pad is
required when branching with BR. The change fixes
fate-hevc-hdr-vivid-metadata when on hardware with BTI support.

  • 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.
