OMX Capture_encode demo

Hi Archith,

  Thank you very much for your reply, and sorry to disturb you again.

Q1

Archith John Bency said:

In the current EZSDK,out of the box, there is no support for a decoder other than TVP 7002. Please go through the below thread for details on how the support would be in releases in the future and how you could possibly work around this limitation:

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/135027.aspx

  I read this thread, and you said

Archith John Bency said:

If you can ensure that the decode is pumping BT1120 embedded sync into the SoC's VIP port, then TVP comoponent is not required to be created/configured/executed. But please keep in mind that this has not been tested in the EZSDK.

  In my situation, the VIN Port of DM8168 is connected with FPGA, I mean I know the video format coming into VIN Port.

  So, the TVP component can be deleted, right? 

  In the future, when the new EZSDK with Vport driver released, can I use that driver for my board?

  I'm sorry , I am not so familiar with these.

Q2

Archith John Bency said:

DEI is a 3 port component 1 input and 2 output. All the three output ports have to be enabled and have to have buffers populated. I think you are not populating any or either of the output ports. You can do an Allocate Buffer on the 2 output ports and do FTB on both the output ports to populate them. Only that, queue the same buffers back into the component without passing it on to other components.

  I enabled the 2 output port of DEI as you said.

  This time it stoped when Capture filled all the 6 buffer of output port.

  Dei component got the ETB message from local pipe, and called OMX_EmptyThisBuffer function with no errors.

  But I cannot see the IL_ClientCbEmptyBufferDone function be called, of course, IL_ClientCbFillBufferDone callback function also not be called.

Hi Archith,

  Thank you very much.

Archith John Bency said:

You need to perform FillThisBuffer calls as well on the DEI output ports.

  It works.

  Thanks again.

lei

hi lei,

     I can't understand the sentence "You need to perform FillThisBuffer calls as well on the DEI output ports",

    Can you give some code piece for demo?

  Thanks

hi chris,

 I did it like this,

  for (j = 0; j < deiComp->numOutport; j++)
  {
        for (i = 0; i < (deiComp->outPortParams+j)->nBufferCountActual; i++)

	{
	  /* Pass the output buffer to the component */
          err = OMX_FillThisBuffer (deiComp->handle,

                    (deiComp->outPortParams+j)->pOutBuff[i]);

	}
  }

Wish could be help.

Lei

hi lei:

    Thanks for your reply and help

    I add your code , and it seems not work

   Below is what is do:

 1.In the function Capture_Display_Example 

   pthread_attr_init (&pAppData->deiILComp->ThreadAttr);

  if (0 !=
      pthread_create (&pAppData->deiILComp->outDataStrmThrdId,
                      &pAppData->deiILComp->ThreadAttr,
                      IL_ClientOutputBitStreamWriteTask, pAppData))
  {
    printf ("Create_Task failed !");
    goto EXIT;
  }

  printf (" file write thread created \n ");


  pthread_attr_init (&pAppData->deiILComp->ThreadAttr);

  if (0 !=
      pthread_create (&pAppData->deiILComp->connDataStrmThrdId,
                      &pAppData->deiILComp->ThreadAttr,
                      IL_ClientConnInConnOutTask, pAppData->deiILComp))
  {
    printf ("Create_Task failed !");
    goto EXIT;
  }

  printf (" dei connect thread created \n ");

  pthread_attr_init (&pAppData->capILComp->ThreadAttr);

  if (0 !=
      pthread_create (&pAppData->capILComp->connDataStrmThrdId,
                      &pAppData->capILComp->ThreadAttr,
                      IL_ClientConnInConnOutTask, pAppData->capILComp))
  {
    printf ("Create_Task failed !");
    goto EXIT;
  }
  printf (" capture connect thread created \n ");

  if (0 !=
      pthread_create (&pAppData->disILComp->connDataStrmThrdId,
                      &pAppData->disILComp->ThreadAttr,
                      IL_ClientConnInConnOutTask, pAppData->disILComp))
  {
    printf ("Create_Task failed !");
    goto EXIT;
  }
  printf (" display connect thread created \n ");

  printf (" executing the application now!! \n");

2. Thread function  IL_ClientOutputBitStreamWriteTask

void IL_ClientOutputBitStreamWriteTask (void *threadsArg)
{
  unsigned int dataRead = 0;
  OMX_ERRORTYPE err = OMX_ErrorNone;
  IL_CLIENT_COMP_PRIVATE *deiILComp = NULL;
  OMX_BUFFERHEADERTYPE *pBufferOut = NULL;
  static unsigned int frameCounter = 0;

  deiILComp = ((IL_Client *) threadsArg)->deiILComp;
  /* use the initial i/p buffers and make empty this buffer calls */
  err = IL_ClientEncUseInitialOutputResources (deiILComp);

  printf (" IL_ClientOutputBitStreamWriteTask \n");
  while (1)
  {
    /* Read filled buffer pointer from the pipe */
    read (deiILComp->outPortParams->opBufPipe[0],
          &pBufferOut, sizeof (pBufferOut));
	printf (" Read frame over %d \n",deiILComp->handle);
    /* write data to output file */
    /*
    fwrite (pBufferOut->pBuffer,
            sizeof (char),
            pBufferOut->nFilledLen, ((IL_Client *) threadsArg)->fOut);
    frameCounter++;
    if(frameCounter == deiILComp->numFrames)
    {
      frameCounter = 0;
	  semp_post(deiILComp->eos);
      pthread_exit(deiILComp);
    }
    */
    
    /* Pass the input buffer to the component */
    err = OMX_FillThisBuffer (deiILComp->handle, pBufferOut);

    if (OMX_ErrorNone != err)
    {
      /* put back the frame in pipe and wait for state change */
      write (deiILComp->outPortParams->opBufPipe[1],
             &pBufferOut, sizeof (pBufferOut));
      printf (" waiting for action from IL Client \n");

      /* since in this example we are changing states in other thread it will
         return error for giving ETB/FTB calls in non-execute state. Since
         example is shutting down, we exit the thread */

      pthread_exit (deiILComp);

    }
  }

}

3.in function I add your code

OMX_ERRORTYPE IL_ClientEncUseInitialOutputResources (IL_CLIENT_COMP_PRIVATE 
                                                       *thisComp)
{
  OMX_ERRORTYPE err = OMX_ErrorNone;
  unsigned int i = 0, j = 0;

#if 0
  for (i = 0; i < thisComp->outPortParams->nBufferCountActual; i++)
  {
    /* Pass the output buffer to the component */
    err = OMX_FillThisBuffer (thisComp->handle,
                              thisComp->outPortParams->pOutBuff[i]);
  }
#endif

  for (j = 0; j < thisComp->numOutport; j++)
  {
        for (i = 0; i < (thisComp->outPortParams+j)->nBufferCountActual; i++)

                    (thisComp->outPortParams+j)->pOutBuff[i]);
	}
  }

  return err;
}

hi lei:

    Could you tell me what's wrong with my code and where should I change the code?

  Thanks

Yes, I just modified my code like this, and It worked in my case.

What are you trying to do? I didn't use VFDC component in my case.

what is your board version and ezsdk version?

If you can post the output message of your code, maybe I can do some help.

Lei 

Hi lei:

      I just want to remove the encode part from the Capture_encode example in the omx demo, my sdk version is ti-ezsdk_dm816x-evm_5_03_01_15,

Hi chris,

I think you don't need IL_ClientOutputBitStreamWriteTask this thread anymore in your case.

Just try to delete these lines of ilclient.c (line 1279~1292)

 pthread_attr_init (&pAppData->deiILComp->ThreadAttr);

 if (0 !=
 pthread_create (&pAppData->deiILComp->outDataStrmThrdId,
 &pAppData->deiILComp->ThreadAttr,
 IL_ClientOutputBitStreamWriteTask, pAppData))
 {
 printf ("Create_Task failed !");
 goto EXIT;
 }

 printf (" file write thread created \n ");

Wish it could be help.

Regards,

Lei

Hi chris,

 Are you using 1080p as your video input?

 Have you tested the video source using the capture sample (Encoder include)? 

 I am sorry that I am a beginner about this part, and I cannot find where you are wrong in your code.

 And now , my board is not work so I can't try your code on my board.

 Maybe you should check your video source.

 Good luck.

Regards,

lei

Lei,

DEI component will work only when both o/p ports are connected. So If you do now want to have encoder, you should just return the buffer received from DEI on the port where encoder is connected. Whenever encode thread was receiving EmptyThisBuffer, you can directly call EmptyBufferDone..this way without calling encoder you can have chain functional.

Regards
