| <p>This structure holds the complete quantization tables. This is an aggregation of all quantization table (DQT) segments maintained by the application. i.e. up to 4 quantization tables are stored in there for baseline profile.</p> |
| <p>The #load_quantization_table array can be used as a hint to notify the VA driver implementation about which table(s) actually changed since the last submission of this buffer.</p> |
