DM6437 Codec Libraries

JumpStart

I just added code to initialize the codec engine in my DM6437 project but I keep getting the following build errors and I believe I may not have included the necessary codec libraries.

symbol                  in file
---------            ----------------
_CERuntime_init      C:\\Vantage\\DM6437\\AppDev\\Debug\\app_codec.obj
_Engine_getLastError C:\\Vantage\\DM6437\\AppDev\\Debug\\app_codec.obj
_IMGENC_control      C:\\Vantage\\DM6437\\AppDev\\Debug\\app_codec.obj
_IMGENC_create       C:\\Vantage\\DM6437\\AppDev\\Debug\\app_codec.obj

Which libraries must I include in my project to resolve the above errors.

Thanks.

You need to create a RTSC configuration project. In that project you tell it that you want to use codec engine and it will pull in the appropriate libraries for you. Details on how to do this are discussed in this article:

Brad provide a good example of doing this on CCS v4.

Considering you are using CCS v3.3, I would suggest looking at your <DVSDK_dir>/examples/video_copy or video_encdec project files as reference.

They use xdcpaths.dat file to specifiy different package files using ---xdcpathsfile="xdcpaths.dat" under XDC settings plus make sure you have the appropriate header files included in your sources similar to

#include <xdc/std.h>

#include <ti/sdo/ce/Engine.h>

#include <ti/sdo/ce/osal/Memory.h>

#include <ti/sdo/ce/image/imgdec.h>

#include <ti/sdo/ce/image/imgenc.h>
