    	Base URL
  -r	Recursive download master and playlists

$ ./m3u82json 'https://mnmedias.api.telequebec.tv/m3u8/29880.m3u8'

Once you have a json, it is very easy to work with it, for example with jq:

Get the Resolution and bandwidth of each rendition:

$ ./m3u82json -r 'https://mnmedias.api.telequebec.tv/m3u8/29880.m3u8' | jq '.Manifest | .Variants[] | {Resolution: .Resolution, BW: .Bandwidth}'
{
  "Resolution": "640x360",
  "BW": 794000
}
{
  "Resolution": "398x224",
  "BW": 64000
}
{
  "Resolution": "416x234",
  "BW": 209000
}
{
  "Resolution": "480x270",
  "BW": 429000
}
{
  "Resolution": "768x432",
  "BW": 1196000
}
{
  "Resolution": "960x540",
  "BW": 2096000
}
{
  "Resolution": "1280x720",
  "BW": 3096000
}

Get the URL of each rendition:

$ ./m3u82json -r 'https://mnmedias.api.telequebec.tv/m3u8/29880.m3u8' | jq '.Manifest | .Variants[] | .URI'
