Yeoh, Hoong Tee da4b2549c6 lavf/rtpenc_jpeg: Retrieve sampling factor from SOF0 
In ff_rtp_send_jpeg, the type is defined based on PIX_FMT and
color-range parsed in. There is limitation on current design
where need to include support newly introduced PIX_FMT such as
AV_PIX_FMT_QSV and there might be more and more in future. Hence,
retrive the sampling factor from SOF0 in JPEG compressed header
directly. This introduces flexibility to handle different type of
new codec introduced in future.

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.
