Andreas Rheinhardt b9a26b9d55 avformat/mxfenc: Remove redundant DNXHD frame size checks 
The actual frame_size is no longer used since commit
3d38e45eb85c7a2420cb48a9cd45625c28644b2e; and the check for
"< 0" is equivalent to the CID being valid. But this is already
checked by avpriv_dnxhd_get_interlaced() (and is actually already
ensured by mxf_dnxhd_codec_uls containing this CID).

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.

Documentation
