Python Function

ret = acl.media.dvpp_set_jpege_config_level(dvpp_jpege_config, level)

Parameters

Parameter	Description
dvpp_jpege_config	Int, pointer address of the encoding configuration data. acl.media.dvpp_create_jpege_config is called to create encoding configuration data.
level	Int, encoding quality level. For the Atlas training product, the value range is [0, 100]. The quality of level 0 is similar to that of level 100. A smaller value in the range of [1, 100] indicates poorer output image quality. For the Atlas inference product, the value range is [1, 100]. A smaller value indicates poorer output image quality. For the Atlas A2 training product/Atlas A2 inference product, the value range is [1, 100]. A smaller value indicates poorer output image quality. For the Atlas A2 training product/Atlas A2 inference product, the value range is [1, 100]. A smaller value indicates poorer output image quality. For the Atlas A3 training product/Atlas A3 inference product, the value range is [1, 100]. A smaller value indicates poorer output image quality.

Parameter

Description

dvpp_jpege_config

Int, pointer address of the encoding configuration data. acl.media.dvpp_create_jpege_config is called to create encoding configuration data.

level

Int, encoding quality level.

For the Atlas training product, the value range is [0, 100]. The quality of level 0 is similar to that of level 100. A smaller value in the range of [1, 100] indicates poorer output image quality.

For the Atlas inference product, the value range is [1, 100]. A smaller value indicates poorer output image quality.

For the Atlas A2 training product/Atlas A2 inference product, the value range is [1, 100]. A smaller value indicates poorer output image quality.

For the Atlas A3 training product/Atlas A3 inference product, the value range is [1, 100]. A smaller value indicates poorer output image quality.
