Encoded Data buffer in basket.c

Hi,

I'm using one of the omx demo with SATA writing enabled. 

I have to copy the encoded data buffer (not the metada but the real data buffer) in a my own unisgned char *buffer.

In basket.c I found a function WriteVideoFrames. But I'm not understanding where encoded data are.

This basket function is called in omx_cmux.c source file from OMX_TI_CMUX_DataNotify  and I think that the encoded data buffer could be the follow one

 

/* Update Inetrface structure to write files to SATA */

be1.pEncodeBuffer = (OMX_U8*)pInBufHeaderPtr->pBuffer;

 

But if I get sizeof ( pInBufHeaderPtr->pBuffer) I hade a dimension of 4. Why?

 

Buffer DATA size 4

Buffer DATA [0] = 0

Buffer DATA [1] = 0

Buffer DATA [2] = 0

Buffer DATA [3] = 1

 

I believe that this dimension has to be equal to the frame size. Isn't it?

I've configured the demo in the right way in order to enable SATA writing:

Bool g_EncDecLoopBack     = FALSE;

Bool g_CmuxDmux          = TRUE;

 

Thanks for help.

    All the file are empty. Why?
