Level
Levels specify the size of the video a decoder must be able to handle. They specify a
maximum bit-rate for the video and a maximum number of macroblocks per second.
Level numbers range from 1 to 5 with intermediate steps (e.g., 1.1, 1.2, 1.3 and etc).
The table below provides a summary of maximum parameters supported by each
H.264/AVC level.
