acl.himpi.venc_set_jpeg_param
C Prototype |
hi_s32 hi_mpi_venc_set_jpeg_param(hi_venc_chn chn, const hi_venc_jpeg_param *jpeg_param) |
|---|---|
Python Function |
ret = acl.himpi.venc_set_jpeg_param(chn, jpeg_param) |
Function Usage |
Sets the advanced QT parameters for a JPEG encoding channel. The Atlas 200/300/500 Inference Product does not support this API in the current version. The Atlas Training Series Product does not support this API in the current version. |
Input Description |
chn: int, encoding channel ID.
jpeg_param: dict, advanced parameter set of a JPEG encoding channel. For details, see hi_venc_jpeg_param. |
Return Value |
ret: int, error code.
|
Restrictions |
This API must be called after an encoding channel is created and before the channel is destroyed. Before this API call, you can tweak the current parameters obtained by using acl.himpi.venc_get_jpeg_param. When the qfactor attribute value in the hi_venc_jpeg_param dictionary is set to 0xFFFFFFFF, the Cb component (blue) and Cr component (red) in the QT must be the same. |
