DM8148 & DVR-RDK H264 codec: CABAC and CAVLC coding

Marat Shchuchinsky

Hello TI' teams,
I'm working with dvr-rdk version 3.5 from udworks, contains H264 encoder version 02.00.04
Please let me know is this encoder supports CABAC coding?
May I explicitly define coding type, I mean CABAC or CAVLC, in encoder creation parameters?
I don't found any info about this issue.

I would also recommend you to check in our Multimedia Software Codecs forum:

Hello,

I am not familiar with DVR RDK but you could check the h264 user guide:

The h264 decoder supports :

IH264ENC_EntropyCodingMode :

For CAVLC coding type:

IH264_ENTROPYCODING_CAVLC
IH264_ENTROPYCODING_DEFAULT

For CABAC coding type:
IH264_ENTROPYCODING_CABAC

What is the hardware platform that you are using here (rev.)?

Best Regards,

Margarita
