vdec channel create bug

You are configuring decoder output buffers as tiled memory. If you want to open more than 8 channels of 1080P you should use non-tiled memory for decoder output buffers. The amount of tiled memory is limited by H/W

thank you for your answer .i don't understant the tiled memory. and i want to know how to configure the decoder output buffers

Set decPrm.chCreateParams[i].tilerEnable = FALSE

yes .that value i use the default value .so it is FALSE .but i don't call the function SystemTiler_disableAllocator()

because i call that function that will has following error:

i want to know this function SystemTiler_disableAllocator() relative to what other params.in the RDK demo usecase

vdec_vdis that source code has no errror when the app run

   tilerEnable  = FALSE;

    if (tilerEnable == FALSE)
    {
        /* Disable tiler allocator for this usecase
         * for that tiler memory can be reused for
         * non-tiled allocation
         */
        SystemTiler_disableAllocator();
    }
    else
    {
        SystemTiler_BucketGeometry_t bucketRes;

        bucketRes.bucketWidth  = SYSTEM_TILER_ALLOCATOR_BUCKET_WIDTH_DEFAULT;
        bucketRes.bucketHeight = SYSTEM_TILER_ALLOCATOR_BUCKET_HEIGHT_DEFAULT;
        bucketRes.minResolution = SYSTEM_TILER_RESOLUTION_CIF;
        bucketRes.setSingleBucketGeometry = FALSE;
        SystemTiler_setBucketGeometry(&bucketRes);
    }

i am sorry .i have somewhere that tilerEnable not change.now i change that to FALSE .then i will has the following errors

after i call the function SystemTiler_disableAllocator,i can init the max channel is 14,then it will be Insufficient Memory,so why?and how to extend the memory?
