Environment Preparation

  1. Copy the sample_dvpp_hlt_ddk executable file generated after compilation to a directory on the device side.

    The dependent .so files are as follows: lib/device/libc_sec.so, libDvpp_api.so, libDvpp_jpeg_decoder.so, libDvpp_jpeg_encoder.so, libDvpp_png_decoder.so, libDvpp_vpc.so, libOMX_hisi_video_decoder.so, libOMX_hisi_video_encoder.so, and libslog.so

    By default, the .so files are in the /usr/lib64 directory on the device side. You do not need to copy them separately.

  1. Save the data file to the directory where the executable file is located, and then run the following command. In the command, paramList is the parameter described in Sample Input Parameters of the DVPP Executor.

    ./sample_dvpp_hlt_ddk paramList
