Nvenc H264 SEI pkg : Who should delete the allocated seiPayloadArray

Hi All

We are inserting SEI payload into our frames :

We are allocating the data before sending the frame for encoding :

 NV_ENC_H264_SEI_PAYLOAD* ptz_sei_payload = (NV_ENC_H264_SEI_PAYLOAD*)malloc(sizeof(NV_ENC_H264_SEI_PAYLOAD));
    uint8_t* ptz_and_camera_matrix_data = (uint8_t*)malloc(sizeof(H264SeiCameraMatricesInjector::H264SeiCameraMatrices)); // Who is responsible to destroy this after use?

    ptz_sei_payload->payloadSize = sizeof(H264SeiCameraMatricesInjector::H264SeiCameraMatrices);
    ptz_sei_payload->payloadType = 5;   // Refer to Annex D.1 of T-REC-H.264-200305-S!!PDF-E.pdf. Payload type 5 corresponds to Unregistered User Data
    ptz_sei_payload->payload = ptz_and_camera_matrix_data;

    picParams.codecPicParams.h264PicParams.seiPayloadArray = ptz_sei_payload;
    picParams.codecPicParams.h264PicParams.seiPayloadArrayCnt = 1;

The above works just fine but my question is who is responsible for deleting the memory pointed to by picParams.codecPicParams.h264PicParams.seiPayloadArray?

Will Nvenc release the memory once the frames has been encoded or how should this be handled.

Thanks in advance!
