How to compile the codec engine with video image coprocessor(HDVICP v2) Engine on DM8148 EVM

SEUNGSIK KWAK

Hello,

I have been working on DM8148 EVM to implement a H.264 decoder which has to support H264 4M pixels - 2048 x 2048 size. As far as I understand, TI OMX doesn't take care of it. I believe that the maximum size would be 1080 - 1920x1080. So, the best bet would be to use Codec Engine framework. I tried to compile example apps on Codec Engine framework. I have followed "Build/Run Instructions for Codec Engine Examples" instruction but the "gmake " complained something like below, even though I have changed xdcpath.mak as the instruction suggests.

../../../../../xdcpaths.mak:647: *** CGTOOLS_C674 is set to "", which is invalid (could not find file "/bin/cl6x*"). Set this in <codec engine examples>/xdcpaths.mak! See the build documentation to correct this error.. Stop.

I think that I don't need CGTOOLS_C674 because the DSP will not be used for H264 decoder. Rather, the HDVICP engine is going to be used. I checked some document as much as possible to figure out how to compile the codec engine with HDVICP engine. So far, I don't have luck.

If anyone has an idea or advice for that, please let me know

Best Regards,

Seungsik Kwak.

Oops, I found a mistake on xdcpaths.mak. I got all example compiled with correct configuration on xdcpaths.mak. Simply speaking of modification of the file(xdcpaths.mak), it looks something like below. I'd like to point where I changed.

I believe that those above would be all modification I made. Hopefully, it helps someone who is looking for the solution like me.

Oops again. It is not real example with HDVICP2 codec but just shows what codec engine looks like using "COPYING" function. I have a big mistake about that. So far I found a couple of threads and "distributed codec engine" library but HDVICP2 code is missing on them - actually the link (http://software-dl.ti.com/dsps/dsps_public_sw/codecs/HDVICP2/index_FDS.html) is broken. Please let me know how to get it or how to get codec engine with HDVICP2 compiled.
