stevxiao 8429aec5e4 avfilter: add d3d12 deinterlace filter deinterlace_d3d12
This commit introduces a video filter `deinterlace_d3d12` that provides
hardware-accelerated deinterlacing using the D3D12 Video Processor.

The filter supports:
 - bob and custom (motion-adaptive)deinterlace modes
 - frame-rate and field-rate output
 - automatic interlace detection

Sample command lines:

1. Software decode with hwupload:

    ffmpeg -init_hw_device d3d12va=d3d12 -i interlaced.ts \
      -vf "format=nv12,hwupload,deinterlace_d3d12=mode=default,hwdownload,format=nv12" \
      -c:v libx264 output.mp4

2. Full hardware pipeline:

    ffmpeg -hwaccel d3d12va -hwaccel_output_format d3d12 -i interlaced.ts \
      -vf "deinterlace_d3d12=mode=custom:rate=field" \
      -c:v h264_d3d12va output.mp4

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.
