|
|
* is based on the statistics that were collected in the following global variables.
|
|
*
|
|
* gu4_cavlc_level_bin_lt_4 represents the number coefficients with abs(level) < 4
|
|
* gu4_cavlc_level_bin_lt_16 represents the number coefficients with 4 < abs(level) < 16
|
|
* gu4_cavlc_level_bin_lt_32 represents the number coefficients with 16 < abs(level) < 32
|
|
* and so on ...
