Bin Peng decc9e643c lavc/aarch64: Fix ff_pred8x8_plane_neon_10 
Fix test failure on aarch64:
./tests/checkasm/checkasm --test=h264pred 479612

The mismatch between neon and C functions can also be reproduced using the following bitstream and command line.

wget https://streams.videolan.org/ffmpeg/incoming/intra8x8pred_10bit.264
 ./ffmpeg -cpuflags 0  -threads 1 -i intra8x8pred_10bit.264  -f framemd5 -y md5_ref
 ./ffmpeg              -threads 1 -i intra8x8pred_10bit.264  -f framemd5 -y md5_neon

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 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.
