How to use the slice mode input with H264 Decoder in HDVICP2?

bing liu

Hi,

I find in H264_Decoder_HDVICP2_UserGuide that the H264 decoder supports slice mode input for low latency purpose. But in mfcw framework, the H264 decoder's input mode is set as frame mode. I run through the codes in \DVRRDK3.5\dvr_rdk\mcfw\src_bios6\links_m3video and could not find where to set the inputDataMode.

So, could someone know how to change the input mode to slice mode in mcfw.

Thanks in advance! Appreciate for your reply!

DVR RDK framework doesnt support slice mode input.

As Sivagamy mentioned slice based decoding is not supported. It requires several changes in DVR RDK to get slice mode functional.

Hi Badri,

Thanks for your reply! There are some examples in \DVRRDK_03.50.00.05\ti_tools\codecs\REL.500.V.H264AVC.D.HP.IVAHD.02.00.08.00\500.V.H264AVC.D.HP.IVAHD.02.00\IVAHD_001\client\test. I will try to use slice mode in mcfw.
