#set_profile_name ⇒ Object

profiles are classified based on aspect ratio, height and number of audio channels

  1. height is 1080 and audio tracks could be (1 track with stereo), (2, 4, 6, 8 tracks and all mono), (1 track with 4, 8 channels)

  2. line 1 applies with aspect ration as 4:3 and 16:9
