DGT Delay stream

Delay an DGT LiveChess stream from digital chess boards with this app

How this java application is working

There are two possibilities how to use this java application.
First one:

• DGT Livechess will run on local computer
• Livechess will copy with FTP uploader files to webserver to temporary directory
• This script will be running on webserver
• Publish directory will be web visible directory

Second one:

• DGT Livechess will run on local computer
• You will have installed FTP server on local (or another one) computer where this script will be running
• Livechess will copy with FTP uploader files to local FTP server
• This script will run on local computer and publish files to web FTP server

Requirements:

1. OpenJDK 21 and higher (for version 1.X and 2.X Java 1.8)
2. DGT Livechess
3. FTP connection settings to webserver
4. FTP Server on localhost (Second scenario)

Install steps

1. Unzip this file on webserver or on a local drive
2. Configure properly properties file
3. Run run_dgt_delay_stream.bat on windows (or samelike on linux)

Properties file - dgt-delay-stream.properties

• directory.livechess - path to directory where livechess files will be uploaded
• directory.backup - working directory. Livechess files will be saved here
• directory.publish - publish directory. This directory will contain files for publishing on webserver. This directory can be direct on webserver as public directory
• directory.finished - finished directory. This directory will contain finished games from games.pgn
• delay.games - delay time of game stream in seconds. To delay game for 15 minutes, you need to set it as 15*60 = 900 (put value 900 there)
• delay.finishedgames - When game will finish, shall be direct published or still shall be delayed. Possible values "true" = it shall be delayed or "false". If "false" value set, this setting requires "onlypgn" as "true", else it will be delayed
• delay.finishedround - When all games will finish, shall all games direct published or still shall be delayed. If true, you need to run script the whole delayed time till end. Possible values "true" = it shall be delayed or "false".
• delay.games.define - You can specify which games shall be delayed. If asterix "*" all games will be delayed. Else you can define number of games separated with semicolon. Example: "1;3;4;9;10". If board numbers defined, this setting requires "onlypgn" as "true", else it will be disabled
• app.refresh - it's application refresh interval. Livechess has this value default set to 10 seconds.This value means "start repeat all checking after 10 seconds after finishing previous one"
• boards.number - by backup directory creating app is checking if pgn contains all expected games and already last game is ending with valid signs (e.g. with asterix or with results). If pgn is not valid, app will destroy this backup and will try to create it again immediately (e.g. ignoring app.refresh value)
• ftp.server - ftp server address
• ftp.login - ftp server login name
• ftp.password - ftp server password
• ftp.active - if value is true, then ftp active mode will be set. Else pasive mode will be used
• ftp.onlypgn - if value is true, only games.pgn file will be checked and uploaded to ftp server. This can be usefull by streams which are using only pgn file for streaming
• ftp.directory - ftp directory can be set to any subdirectory on ftp server
• live.pgn - when you are delaying stream, you can put also on ftp live stream for commentary

Some hints how it's working

• If you let ftp.server empty in property file, Files will not be uploaded to ftp server. They will be only copied to publish directory. This is fine when this script will be running on webserver.
• After application start if publish directory is empty, current livechess files will be directly published. After this first check every next time the file will be published only when file was changed. For file change app is detecting datetimeModify property of file and Md5 checksum.
• FTP connection to server is opening only when at least 1 file will be copied or publish directory contains at least one directory
• Application is copying all files from backup/publish directories. It doesn't check if they are from DGT Livechess or not (check property file - setting ftp.onlypgn=false)
• If you want to publish players to webservice and don't want to wait for delay.games time you only need to clean all files from publish directory
• You can delay all games or some of them
• You can choose if finished games are still delayed or they will be directly published
• You can choose how big shall be the delay
