And I have to use another codec write by mysel at the same time which also use L2 cache .Would this cause some cache corruption?

thanks

Can you kindly provide us the version of the codec being used? Can you as well check at a lower bit-rate?

hi, Girish

     Thanks for your reply . H.264 Encoder Version 01.10.02.

      Did you mean params.maxBitRate        = 20000000 is too big. I will try as you suggested.

Hi

    I have tried different bitrate ,but the speed is still near 10 fps.

   Can someone from TI  provide more useful suggestion.It's very important to me.Wating for your help.

Hi,Girish

     Thanks for your sincerely help.

Hi，Girish

    I face a new problem ,the outBufSize I get  is 2088960=1920*1088.It seems too big.The way I get the outBufSize is posted below:

     hVe1 = Venc1_create(ce, "h264fhdvenc", &params, &dynParams);

    outBufSize = Venc1_getOutBufSize(hVe1);

   Can you help to analyse ，where the problem may be.

Regars,

David

Hi David,

I don't understand why it's a problem ? You can't know before encoding the size of the encoded frame so you have to allocate enough memory space to be sure you will push in the encoded frame so :

When you do that :

outBufSize = Venc1_getOutBufSize(hVe1)

after you may call a memory allocator of this size like :

        videnc1->hOutBufTab = gst_tidmaibuftab_new(3,

                outBufSize, BufferGfx_getBufferAttrs (&gfxAttrsOut));

But after you can create a buffer after encoding process with :

*outBuf = gst_buffer_new_and_alloc(Buffer_getNumBytesUsed(videnc1->hEncOutBuf));

and outBuf will be of the size of the encoded frame. (it's the code from TIVidenc1.c from gstreamer TI)

If it's not helping you , please give more info about your "problem".

Hi,Mike

     The problem has been solved .Thanks for your help.

David, Can you confirm that your original query related to performance is resolved?

Yes,when I only run h264 codec .The speed is 30 fps.

And I have to use another codec writed by myself at the same time which also use L2 cache .It  cause some cache corruption.

Engine_createNode> Remote node creation FAILED (0x80008008).//hVe1 = Venc1_create(ce, "h264fhdvenc", &params, &dynParams);

MY own codec need use 60KB L2 cache.I wonder if the two codecs can run together in one application.

David

If you're resource constrained, this may help you understand how codecs can share resources:

Sharing resources may impose other constraints you may not be willing to accept (e.g. swapping context in/out may introduce new overheads), but wanted to make you aware of the option.

Hi， Chris

      First ，sorry for so late reply .

I set my server.tcf according the cs2dm6467 "CS" demo like below:

/* Specify the L2 memory setting */
var device_regs = {
    l1PMode: "32k",
    l1DMode: "32k",
    l2Mode: "64k"
};

...

if (config.hasReportedError == false) {

bios.MEM.instance("IRAM").createHeap = 1;
bios.MEM.instance("IRAM").heapSize = 0x00010000;//0x00008000;//0x8f18;// 0x00010000;
bios.MEM.instance("IRAM").enableHeapLabel = 1;
bios.MEM.instance("IRAM").heapLabel = prog.extern("IRAM_HEAP", "asm");
   prog.gen();
}

Now the h264 codec can work correctly. But my own codec "video_copy" which also need "64K" L2 memmory can't work.

The "video_copy" codec asks for L2 cache in "link.cmd " like below:

SECTIONS

{

.video_copy:     >   CACHE_L2

}

when I run the program on dm6467t board .It gives no error information ,just stucked.I must reset the board.

Can you help figure out where the problem may be.

Regards,

David.
