Ting Fu 87cb24a1ca dnn/openvino: support run inference via GPU 
for enabling OpenVINO GPU please:
1. install required OpenCL drivers, see: https://github.com/intel/compute-runtime/releases/tag/19.41.14441
2. build OpenVINO c lib with GPU enabled: use cmake config with: -DENABLE_CLDNN=ON
3. then make, and include the OpenVINO c lib in environment variables
detailed steps please refer: https://github.com/openvinotoolkit/openvino/blob/master/build-instruction.md

inference model with GPU please add: optioins=device=GPU

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 a mean to alter decoded Audio and Video through chain of 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.
