Search for occurence of video clips in a database of videos.

HOW TO RUN

Installations

• Install all the dependencies from requirements.txt
• Install ffmpeg

Database setup

• In this project we use postgres as the database engine.
• Create a database and name it 'MultimediaDB'.
• Run the sql script inside /DB-create directory.

Data population

• Once the db table has been created, the next step is to process all the videos to be inserted into the database.
• All videos are present in the /DB-populate/videos directory.
• All videos must be named as videoX.mp4 where X is an integer value.
• Run

  chmod +x generate-json
  ./generate-json
  

• This generates json objects and adds them to the /DB-populate/videos_json directory.
• Run

   chmod +x insertAllVideos
   ./insertAllVideos
  

• This inserts all the json objects to the database.

Querying

• Now the database is populated and ready to be queried.
• Clear the queries/tesing directory and insert the video query.
• Run

  chmod +x query
  ./query
  

• This finds the video number and the starting time of the query clip in the video.
• Uncomment line #61 in query.py to view the video in VLC player.
