Are the parameters always delimited by commas ? In which case you could 
modify the regular expression

  line =~/(\w*)=(.*)/

Then

  $2             #=> "MPEG-4,390000,700000,24000"
  $2.split(",")  #=> ["MPEG-4", "390000", "700000", "24000"]

Returns you the values after the '=' sign in line as an array. For more 
power you could pass this sub-string to a CSV parsing library such as 
FasterCSV.
