H.264 Encoder features on DM8168 - ROI Encoding/Perceptual rate control/FMO/ASO

Hi Jongpil,

Yes the ROI and Perceptual rate control as mentioned in spry195 are implemented in H.264 encoder on DM8169.
These are 2 different components. H.264 encoder expects some sort of ROI and perfroms the percpetual quantization and there is a seperate component which does the ROI generation. Both components are available on DM8169.

Dear Pramod

Thanks for your response.

Did you mean DM8169 as a DM8168?

I downloaded the latest version of EZSDK. The version is 5.05.

I've just found two documents H.264 encoder and decoder.

As your response, both components(ROI generation and H.264 encoder) are available on DM8618. Then how can I test it?

Do I need some source code modification? Could you give me a sample code to test perceptual rate control / ROI encoding?

Best regards,

Jongpil

Hello Pramod

I need more questions regarding ROI and PRC.

Are two implementations compatible the other H.264 Decoder?

Until now I understand that H.264 Encoder FMO feature is needed feature to enable ROI Encoding or Perceptual Rate Control.

But I can't any word that TI H.264 Encoder can support it. So I think this implementation is TI's proprietary, isn't it?

And I'm looking forward to hear any information from you ASAP.

Hello Pramod,

Could you update for me?

Best regards

Jongpil.

I meant DM8169- not DM8168. You need to speak to sales representative of your area to understand any plans of DM8169 SDK showcasing ROI.

Regarding  -your other questions - I think your below understanding is not right

"Until now I understand that H.264 Encoder FMO feature is needed feature to enable ROI Encoding or Perceptual Rate Control."

FMO is not required for ROI encoding and PRC. ROI and PRC controls the quality factor of specific regions of frame - and has nothing to do with the coding order of macroblocks. These are still coded in raster format. FMO controls the order in which MBs are coded in streams. So the streams generated are H264 compliant and can be decoded with any compliant H264 decoder. The coding mechnism has nothing TI proprietary but the way rate control allocates QP to different regions is TI proprietary.

Hello Pramod,

Thanks for your response.

I cant' any information regarding DM8169 in your web site.

The document(no. spry195) says that TI's engineer have implemented ROI detection algorithm(skin-tone macroblock detecton) and ROI encoding on DM816x processor. In this case DM816x processor is DM8169 not DM8168? Please confirm this question.

Thanks.

Hello,

Could you check it for me? "Skin-tone macroblock detection) and ROI encoding is described in white paper are implemented and tested on DM8169?"

It's my final question.

Best regards,

Jongpil.

Hello Pramod,

Thanks for your response.

DM8169 is not officially announced, right? I can't any information regarding DM8169.

What is different with DM8168? DM8168 doesn't support ROI Encoding with the firmware of DM8169, why?

Best regard,

Jongpil
