VideoProcessingService

A c++ backend rest server provide a simple api for client to demux and docde network video stream or video file

Description

VideoProcessingService is a rest server aim to provide a simple api for application or web developer to get information or data from a video streaming(RTSP, RTMP, HLS, etc.) or a video file, developers can get the following information and data from this service

• Video
  • Image width and height
  • Video length with milliseconds
  • RGB data and its related pts
• Audio
  • PCM raw data and its related pts

Feature

The following module have been implement and integrate to the processing flow

• Demux (API)
• Decode (API)
• Color space converter (API)
• Audio resample (API)

Example

• Demo file
  Provide a sample demostrate how to get video data and information from this service and showing image with OpenCV and playback audio with RtAudio

• Test file
  Provide a sample demostrate how to get video data and information directly from C++ backend and showing image with OpenCV and playback audio with RtAudio (This method do not need the reset server, but need to compile all c++ backend and integrate to your project)

• Todo

  • Plugin for Qt
  • Plugin for flutter

How to run this server

# pull image from dockerhub
sudo docker pull andywang0607/video-processing-service 

# Run docker (you can use another port)
sudo docker run --rm -p 9080:9080 andywang0607/video-processing-service 

How to build this server

1. Prepare third-party library

   • Setup vcpkg

     $ git clone https://github.com/microsoft/vcpkg
     $ cd vcpkg
     $ bootstrap-vcpkg.bat
     

   • Install required library

     $ ./vcpkg install ffmpeg:x64-linux
     $ ./vcpkg install pistache:x64-linux
     $ ./vcpkg install nlohmann-json:x64-linux
     

2. Build this project

   $ cd $PROJECTPATH
   $ mkdir build
   $ cd build
   $ cmake ..
   $ make
   

Note

This is my weekend project just a practice for building a rest service with c++.
Get decode video and audio data from this service is not a efficent methoud indeed,
But it is quite simple and easy for developer to write a video player in every ui framework
