Haihao Xiang 412d43b09a lavfi/vf_vpp_qsv: only add the given output sw format to output pad 
Otherwise the output format is not changed when output is in system
memory. For example, the output format is still p010le in the following
case:

$ ffmpeg -qsv_device /dev/dri/renderD128 -f lavfi -i testsrc -vf
"format=p010le,vpp_qsv=extra_hw_frames=8:format=nv12" -f null -
...
Output #0, null, to 'pipe:':
  Metadata:
    encoder         : Lavf60.4.100
  Stream #0:0: Video: wrapped_avframe, p010le(tv, progressive), 320x240
[SAR 1:1 DAR 4:3], q=2-31, 200 kb/s, 25 fps, 25 tbn

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.
