Haihao Xiang 5717fbbea2 configure: don't warn deprecated symbols from libvpl 
libvpl deprecated some symbols (e.g. MFX_EXTBUFF_VPP_DENOISE2 is used to
replace MFX_EXTBUFF_VPP_DENOISE), however the new symbols aren't support
by MediaSDK runtime. In order to support the combination of libvpl and
MediaSDK runtime on legacy devices, we continue to use the deprecated
symbols in FFmpeg. This patch added -DMFX_DEPRECATED_OFF to CFLAGS to
silence the corresponding compilation warnings.

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.
