Hi,

I am trying to run  video_loopback in the apps of dmai_2_10_00_17 for dm365,but it couldn't work,the problem is as follows:

vpfe ccdc capture vpfe ccdc capture.1: hpitch = 720, vpitch = 576, bpp=2                                                                    

[DMAI][capture.cvpfe ccdc capture vpfe ccdc capture.1: hpitch=720,vpitch=576,bpp=2] videoStd=6,width=720,height=576                                                                                                          

[DMAI][capture.c] 2 videoStd=6, width=720, height=576                                                                                        

pixelFormat 1=842094158, 2=1498831189                                                                                                        

[DMAI][CAP]                     12                                                                                                            

Failed to create capture device

the problem seems to be the different of the pixelFormat ,so i try to change the Capture_create() in the Capture.c ,but no matter how

i change or add  the  messages to print, no response to me.So i am puzzled whether the Capture.c links to the appmain.c .Anyone can tell me how to fix it?

Thank you !

    First,test the demo,dont't compile it.To run them enter this directory on the target, Running the DMAI apps,in the target # cd /usr/share/ti/ti-dmai-apps/ :To do video loopback from 720P component input to 720P component output execute:

    target # ./video_loopback_dm365.x470MV -O component -I component.

    And then,if  the demo can work correctly,you can compile the demo in the dvsdk by your self.

    In the dm365_sdk\dmai_2_20_00_15\packages\ti\sdo\dmai\apps,check the directory of the Rules.make,make sure you can compile it correctly.
