dvblast creates MPTS output using -d switch but need to use a configuration file to filter SIDs or it's PIDs. In this case dvblast creates SPTS too, according to destinations specified in configuration file.
The main goal of this patch is to continue to use configuration file to get benefit from per stream options but preventing SPTS outputs and having just MPTS output using -d switch. This feature can be enabled using -4 <config-file> parameters.
Sample config file lines for -4 switch (no SPTS destinations, just a placeholder);
0 1 SID
0 1 SID PID,PID,PID
Usage example;
> dvblast -4 file.conf ...
You can keep continue to use -c <config-file> parameters with the file which has original format of configuration lines when this feature is not necessary.
The MPTS output can be sent to a UDS target. For this purpose the socket path will be defined with unix:// prefix. In example, when the socket is created at "/var/run/sock", the -d swhich whill have parameter like;
-d 'unix:///var/run/sock'
dvblast terminates if the socket file not exists or on an error while using the socket.
CI status information can be exported to a local file. The environment variable DVBLAST_CISTATS is used for this purpose since there is no switch left to use.
> DVBLAST_CISTATS="/path/to/file.log" dvblast -4 file.conf -d unix:///path/to/sock ...
The log file will be updated periodically. The -6 or --print-period switch can be used to set interval. The default value 2 seconds is used when not specified.
Following information will be exported;
