Reporting

At this version library has no reporting capabilities.

You will have to write a wrapper for this tool which will capture all of the failed output and will email it to you or report to somewhere.

Pseudo code looks like this:

$playlists = [...many playlists to check...];
$failed_reports = [];

// for each given playlist - make checking
$output = [];
$return_code = 0;
exec('vendor/bin/hls-monitor playlists '.implode(",",$playlists), $output, $return_code);   
   
if($return_code) {
   // there were problems with this palylist
   $failed_reports[] = $output;
}


// then report if anything is not good
if(count($failed_reports)) {
   // mail reports to somewhere
}
