* @brief In cavlc encoding, a lut is used for encoding levels. It is not possible |

|
* 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 ... |
