Members

Member	Description
left_pics	Number of pictures to be encoded. In the JPEGE image encoding scenario, this parameter is not supported by the following models: Ascend 950PR/Ascend 950DT Atlas A3 training products/Atlas A3 inference products Atlas A2 training products/Atlas A2 inference products Atlas 200I/500 A2 inference products
left_stream_bytes	Number of bytes that are not fetched by the user in the stream buffer. In the JPEGE image encoding scenario, this parameter is not supported by the following models: Ascend 950PR/Ascend 950DT Atlas A3 training products/Atlas A3 inference products Atlas A2 training products/Atlas A2 inference products Atlas 200I/500 A2 inference products
left_stream_frames	Number of frames that are not fetched by the user in the stream buffer. In the JPEGE image encoding scenario, this parameter is not supported by the following models: Ascend 950PR/Ascend 950DT Atlas A3 training products/Atlas A3 inference products Atlas A2 training products/Atlas A2 inference products Atlas 200I/500 A2 inference products
cur_packs	Number of current stream packets.
left_recv_pics	Number of remaining frames to be received. This member is valid after the number of frames to be received is set by calling hi_mpi_venc_start_chn. In the JPEGE image encoding scenario, this parameter is not supported by the following models: Ascend 950PR/Ascend 950DT Atlas A3 training products/Atlas A3 inference products Atlas A2 training products/Atlas A2 inference products Atlas 200I/500 A2 inference products
left_enc_pics	Number of remaining frames to be encoded. This member is valid after the number of frames to be received is set by calling hi_mpi_venc_start_chn. In the JPEGE image encoding scenario, this parameter is not supported by the following models: Ascend 950PR/Ascend 950DT Atlas A3 training products/Atlas A3 inference products Atlas A2 training products/Atlas A2 inference products Atlas 200I/500 A2 inference products
is_jpeg_snap_end	JPEGE snapshot completion flag. Reserved parameter, not supported currently.
release_pic_pts	Reserved parameter, not supported currently.
stream_info	Stream information. For details, see hi_venc_stream_info. This parameter is not supported in the JPEGE scenario.

Precautions

If frame loss occurs in the snapshot frames received by VENC, the is_jpeg_snap_end flag may fail to correctly mark the end of snapshot.
