Linjie Fu 9f14396a51 lavfi/vf_scale: use default swscale flags for scaler 
Currently the default swscale flags for simple filter graph is bicubic,
however for complex filter graph it uses bilinear as decleared in scale
filter.

$ffmpeg -v verbose -i input.mp4 -vf format=yuv420p,scale=800x600 -an -f null -
[Parsed_scale_1 @ 0x7f86d2c160c0] w:1920 h:1080 fmt:yuv420p sar:0/1 -> w:800 h:600 fmt:yuv420p sar:0/1 flags:0x4

$ffmpeg -v verbose -i input.mp4 -filter_complex format=yuv420p,scale=800x600 -an -f null -
[Parsed_scale_1 @ 0x7f8779e046c0] w:1920 h:1080 fmt:yuv420p sar:0/1 -> w:800 h:600 fmt:yuv420p sar:0/1 flags:0x2

Use default swscale flags (bicubic currently) for scale filter.
- Remove flags="bilinear" from vf_scale
- Update the FATE refs

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.

Documentation
