Json format description:

Parameters with no parents:

• "file" : "path to file" - scheduler write to a file or send a udp stream
• "ip" : "ip" , "port" : port - ip address and a port to send a udp stream
• "bitrate" : bitrate - the bitrate of the stream, it must be the same for every file
• "cache size" : "size" - common cache size, you can use K to set the size in kilobytes and M in megabytes
• "accumul" : "size" - size of filled cache part, you can use K to set the size in kilobytes and M in megabytes
• "ttl" : "number" set ttl
• "priority" : number - set the process/thread priority
• "ts_in_udp" : number - the number of ts packets in one udp packet
• "stream" : [items] - contains items of a schedule

Parameters with "stream" parent:

• "file" : [files] - the sequence of files to play, it must the sequence, even if we play one file, "file" is used for a sequence with files that have different names
• "sequence" : [files] - the sequence of files to play, every file has a name concatenated with a number within a sequence
• "start_ind" : index - the started number of the sequence to play
• "end_ind" : index - the last number of the sequence to play
• "digits" : number - the number of digits described the file position in the sequence
• "shell_exec" : "shell command" - the shell's command to run before file playing
• "shell_file" : "path to file" - a file to be executed before file playing
• "schedule" : {parameters} - a description of time when to play files

Parameters with "schedule" parent:

• "day of week" : [days of week] - the list of days of week when to play files
• "day" : [dates] - the list of month days when to play files, it should be used instead of "day of week"

Reread configuration:

You need to send SIGHUP signal to force the shedts to reread the json configuration. You may do from command-line:

kill -1 pid

You can get a process pid with:

ps -e | grep schedts

"ip" : "239.0.0.10",

"stream" : [
   {
     "file" : ["/ProjectsP/ts/swm.ts", "/ProjectsP/ts/gt.ts"],
     "shell_exec" : "ps -e",
     "schedule" : {
       "day of week" : ["Tue", "Sun"],
       "time" : ["12:26"],
       "month" : ["every"],
      }
   },
