vcap and vdec display on one screen at the same time

i mean that whether the cap data and dec data can be displayed through the swms link?

tks!

Yes t possible. Have a mergeLink before swms with inputs from Capture and Decode and then SwMs can display from both capture and decode. You can check any usecase like

/dvr_rdk/mcfw/src_linux/mcfw_api/usecases/ti816x/multich_hd_sdi_dvr.c

/dvr_rdk/mcfw/src_linux/mcfw_api/usecases/ti816x/multich_hybrid_dvr.c

/dvr_rdk/mcfw/src_linux/mcfw_api/usecases/ti816x/multich_progressive_vcap_venc_vdec_vdis.c

/dvr_rdk/mcfw/src_linux/mcfw_api/usecases/ti816x/multich_hybrid_encode.c

for reference

ok.thanks for your answer .i will try again

i do that like you say. the cap data and dec data now can be display on the screen. now i want to know that the dec data and the cap data are how to display the sw window? whether is the dec data is display on the window 0-14,and the cap data is sent to the window 15? i want to  know what is the rule,and how can i set?

tks

The channels numbers depends on the mergelink configuration.Say you have 16 channels from capture and 16 channels decode.

For configuration:

Capture --> Input Q0 -->

                                         MergeLink -> OutputQue (0 - 15 capture Channel, 16 - 31 decode channels)

Decode --> Input Q1 -->

i have 2 cap and 16 dec .you mean that if the cap is input Q0 then the 0-1 window will display the cap data,and the dec is input Q1,the 2-17 winodw will display the dec data ?

Yes that is correct
