• av_format/hlsenc : fix %v handling by format_name function

  av_format/hlsenc : fix %v handling by format_name function
  Hi All,
  When multiple variant streams are specified by var_stream_map option, %v
  
  placeholder in various names ensures that each variant has its unique
  
  names. Most of %v handlng is done in format_name function. Currently
  
  in this function the result buffer is the same as the
  
  input pattern buffer, so you must allocate it before calling format_name
  
  function. It also means, that it is silently assumed that the result
  
  string will NOT be
  
  longer that the pattern string. It is true most of the time, because %v
  
  may appear only once in the pattern string and number of variant streams
  
  is less than 100 in practical cases. But theoretically it will fail if
  
  specified number of variant streams is greater than 100 (i.e. longer
  
  than 2 digits).
  
  This patch fixes this behaviour by altering format_name function to
  
  allocate the
  
  result buffer and return it to the caller.
  Please, review this patch.
  best,
  Bela
