Sends source images for video or image encoding.

C Prototype

        
             hi_s32 hi_mpi_venc_send_frame(hi_venc_chn chn, const hi_video_frame_info *frame, hi_s32 milli_sec)

Python Function

        
             ret = acl.himpi.venc_send_frame(chn, frame, milli_sec)

Parameter	Description
chn	Int, encoding channel ID.
frame	Dict, dictionary of original image information. For details, see hi_video_frame_info.
milli_sec

Return Value	Description
ret	Int, error code. 0 indicates success. Other values indicate failure. For details, see VENC/JPEGE Return Codes.

The size of an original video image must be the same as that of an encoding channel. The size of an original JPEGE image must be less than or equal to that of an encoding channel.
Ensure that an encoding channel has been created and started receiving images.
During encoding, the input buffer can be deallocated only after acl.himpi.venc_get_stream is called to obtain the result.
For details about the input and output restrictions on video encoding, see VENC Functions and Restrictions.
For details about the input and output restrictions on image encoding, see JPEGE Functions and Restrictions.
