Function Description

Sets the frame copy parameter.

Prototype

hi_s32 hi_mpi_venc_set_streamcopy_param(hi_venc_chn chn, const hi_venc_streamcopy_param *streamcopy_param)

Parameters

Parameter	Input/Output	Description
chn	Input	Encoding channel ID. For the Atlas inference product, the value range of the encoding channel ID is [0, 256). The JPEGE and VENC functions share channels. The maximum number of channels is 256.
streamcopy_param	Input	Frame copy parameter.

Parameter

Input/Output

Description

chn

Input

Encoding channel ID.

For the Atlas inference product, the value range of the encoding channel ID is [0, 256). The JPEGE and VENC functions share channels. The maximum number of channels is 256.

streamcopy_param

Input

Frame copy parameter.

Returns

0: success
Other values: failure. For details, see VENC/JPEGE Return Codes.

Restrictions

Only H.264/H.265 encoding channels support this API.
When frame copy is enabled with a copy interval set to 0, the H.265 SPS/Slice follows the new protocol, while the H.264 protocol remains unchanged. The copy interval can be adjusted later, and there is no need to request an I-frame for the copy to take effect in this case. If frame copy is disabled, it can be dynamically enabled later, but it only takes effect in the new IDR.
After the frame copy function is enabled, the time domain TMV automatically becomes invalid.
