hi_mpi_venc_set_streamcopy_param

Description

Sets the frame copy parameter.

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 at a later time, but it only takes effect in the new IDR.
• After frame copy is enabled, the temporal motion vector (TMV) automatically becomes invalid.
