YUV422SP to YUV422P on DM6467

Jaden Ghylin102047

I am working with the JPEG Codec provided via the link below. I am attempting to use the encode demo provided with the DVSDK 3.10 to use the JPEG encoder codec instead of the h264 one.

http://software-dl.ti.com/dsps/dsps_public_sw/codecs/C64XPlus_Video/index_FDS.html

The issue is that the JPEG Codec doen’t support the YUV422SP color space. I need to perform a color space conversion from YUV422SP to YUV422P and I’m trying to figure out the means to do so.

It appears the C6EZAccel libraries can do support this. However, the wiki page for C6EZAccel says that its end of life. I am looking for any suggestions on how to perform the colorspace conversion. Is it ok to use C6EZAccel even though it’s no longer supported?

I’ve also tried using the CCV module in the DMAI, but it appears it can only convert YUV422SP to YUV420SP (semi planar only) and vice versa.

Hi Jaden,

Your understanding is correct, we no longer support C6EZAccel but that package did have support for YUV422SP to YUV422P. You could use the software package as is or use it as a reference to create your own iUniversal algorithm that can be integrate in your codec server. If you want to create your iuniversal codec, I recommend that you look at the steps of creation of the codec described here:

It may be simpler if you add the color space conversion functionality to the codec? Do you have the source code the codec? I can provide you optimized DSP code to do this conversion which you can integrate. Let me know if you would prefer this approach. I cannot provide this source code directly on the forums so send a request for this code on the DSP software developers list mentioned below:

Hi Jaden,

I have sent the code to you on the software developers list .Let us know if you have any further questions in integrating the code with the codec.
