hi, all

I want to fulfill the function of object counting ,but after I type the "./run.sh" I only see the 

5 items as follow

 1: VCAP + VENC + VDEC + VDIS - Progressive SD Encode + Decode
 2: VCAP + VENC + VDIS - SD Encode ONLY
 3: VCAP + VENC + VDEC + VDIS - Progressive HD Encode + Decode
 4: VDEC + VDIS - SD/HD Decode ONLY
 a: 960H DVR usecase

I search for the function for a while still never see the function of count function.

Could anyone who could tell me about how to implement the object count

thanks a lot~

    This algorithm is enabled in demo-1 (Progressive SD EncDec) . By default TripZone has been enabled for 1-channel. This can  be checked at the menu option "l: Print SCD Analytics Config of All Channels" inside capture setting.

    Once the demo-1 is selected, user is asked to provide algorithm configuration file i.e. "ini" file. There are sample files in ~/demo_ini/ folder. If user does not specify any file, by default /opt/dvr_rdk/ti816x/demo_ini/demo_init/dmvalConfig.ini file is selected. It specify algorithm configuration of 1-channel. 

    You can go through the ini file for more details about parameter to be set. To Select Object Count select the detectmode = 32 (ALG_LINK_SCD_DETECTMODE_COUNTER).

    Currently result of the algorithm is exported to A8. It is then processed to print it on console and/or showcase on graphics. All these tasks are done in demo_scd_bits_wr.c. Please go through function Scd_VaProcessMetaData() for any further details on result processing and console prints. You can add a print to display number of counted object, this data is present in AlgLink_ScdResult structure.
