Detailed Description

Encoding quality level.

The encoding quality could be set through this structure, if the implementation supports multiple quality levels. The quality level set through this structure is persistent over the entire coded sequence, or until a new structure is being sent. The quality level range can be queried through the VAConfigAttribEncQualityRange attribute. A lower value means higher quality, and a value of 1 represents the highest quality. The quality level setting is used as a trade-off between quality and speed/power consumption, with higher quality corresponds to lower speed and higher power consumption.
