Christophe Gisquet cb335b3af2 dvenc: fix 2x4x8 (interlaced) weight table 
Since the decoder has been fixed to output something similar to
other implementations, the encoder weight table needed this fix.

Reference PSNR values on a progressive sequence (from tiny_psnr)
from a chained encoding and decoding:
Full progressive: stddev:    0.74 PSNR: 50.69 MAXDIFF:   19
Before:           stddev:    1.43 PSNR: 44.97 MAXDIFF:   17
This patch:       stddev:    0.76 PSNR: 50.44 MAXDIFF:   14

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 analisys tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
