image storage using DM6446 Davinci evm

hello ; 

i'm  running  encode demo using DM6446 EVM, when i press 'ctrl c' the demo stops, i wonder where can i find that image after running demo, or what changes do i have to do in display.c file in order to store image.

i hope that anyone helps me 

thanks 

  • Hi Sisia,

    Welcome to E2E Forum,

    Have to tried to save image by running encode demo , if it works for you successfully then you can make changes in encodedecode demo to save the image.


    try to run

    ./encode -v test.mpeg4 -r 352x240 -O component

    You can also read the following docs.

  • hi Arvind ; 

    thank you for reply, actually when i put ./encode -v test.mpeg4 -r 352x240 -O component it shows invalid option -o  and also -o doesn't exist in  the encode.txt file, have you any idea about what kind of changes do i have to do in the encodedecode demo, i found some information in the link below e2e.ti.com/.../75612 but it's steel not clear enough for me :( 

    best regards 

  • hello Arvind,
    In fact, by default the encode demo saves the video file, now i want to transfer that file to a usb 2.0 or a SD card. but when i connected myusb key to my DM6446 EVM it wasn't detected by OS linux, the same is for my SD card!
    could you plz tell me how could i resolve this problem
    thank you
  • Dear Sisia,
    Are you using default kernel (uImage) for DM6446 EVM ?
    By default, USB and SD card support has been enabled in driver.
    Please make sure that you have enabled the USB/SD card support if you are using customized kernel.
