    This seems to be wrong buff addr passed to ducati.

    Please, try with ducatijpegdecvpe element.

    Hope this helps.

    Hello,

    If there is no caps filter after vpe then the vpe will be not use, since the input resolution and output is the same, the format also.
    So please set capsfilter after vpe but resolution or format in the capsfilter should be different from the input and give a try.

    Hope this helps.

    Hello,

    Let's say the input is 1920x1080 YUY2, after vpe will be 720x480, NV12.

    ... ! ducatijpegdecvpe ! 'video/x-raw, format=(string)NV12, width=(int)720, height=(int)480' ! ....

    processors.wiki.ti.com/.../Processor_Training:_Multimedia
    In your case you must set capsfilter and resolution or format must be different from the input to make vpe to be use.

    Hello,

    One more note, I see you are using PSDK 3.02 and ducatih264enc. I guess you have applied this patch for mem leak issue in ducatih264enc :
    git.ti.com/.../7205d7cb75944e816622d5daca88804819ff16d3
    If not please apply it before to start the test again.

    Hi Margarita,

    Yes i have already applied memory leak patch.

    It has been 2 days and 4 hours  since i started my test.

    For now, it seems the application is working fine.

    Still i want to test it for some more days, to check if there is any kind of issue.

    Regards,

    Prerak
