Can buffer alloced by Utils_memBitBufAlloc share to A8?

BitBuf is allocated from SR0. Refer Utils_mem.c. You need to do adjust memory map to have more memory for SR0.

Hi Sivagamy:

Thanks very miuch!

So if i share data to A8, i must use Utils_bitbufGetEmptyBuf?

And I want to set buffer size for Utils_bitbufGetEmptyBuf, how to do ?

Thanks.

1. Refer the bitBuf usage in encLink_common.c.

2. If you want to increase the memory used for bitBuf, you will have increase SR 0 size.

Hi Sivagamy:

I donn't understand what you say!

Because I only want to increate the buffer size which I call bitbufGetEmptyBuf, bitbufGetEmptyBuf returned!

 For example, when called bitbufGetEmptyBuf, it will return pOutBuf that contain405504 size. I want to it contain 1M memory size.

is it possible?

Which bitBuf Handle are you using when you call Utils_bitbufGetEmptyBuf()?

BitBuf queue creation is done via these steps-

1. Create a queue - Utils_bitbufCreate() which just creates queue elements.

2. Allocate memory for individual buffers using Utils_memBitBufAlloc(). This is where buffer size comes into picture

3. Put individual buffers into bit buf queue using Utils_bitbufPutEmptyBuf().

4. Steps 2 & 3 has to be done for required no. of buffers

5. Later when you call Utils_bitbufGetEmptyBuf, the buffers returned will have the same size as used in Step 2.

Hope you understand how this mechanism works. Reference in encoder link. I am not sure of your usage. Give a clear picture of what you are trying to do.

If you want to get decoded frame data on A8 use ipcFramesOutLink -> ipcFramesInHost link connection. No other changes are required. Any change like trying to do Utils_memAlloc and trying to do memcpy are wrong and will not work.

Hi Sivagamy:

Thanks. I will try it.

Using these step, then

1 Utils_bitbufGetEmptyBuf(bufOutQue, &pOutBuf, 0, BIOS_NO_WAIT); 

2 encode

3 ti_sysbios_family_c64p_Cache_wb(pOutBuf->addr, pOutBuf->fillLength, ti_sysbios_family_c64p_Cache_Type_ALL,FALSE);

4 System_sendLinkCmd(pObj->outQueParams[ALG_LINK_SCD_OUT_QUE].nextLink,SYSTEM_CMD_NEW_DATA);

in Step 1, the pOutBuf that returned is the buffer I alloc?

Hi Badri:

Thanks very much!

Using pOutBuf that alloced by Utils_bitbufGetEmptyBuf(bufOutQue, &pOutBuf, 0, BIOS_NO_WAIT),

I can encode and compress frame data.

But sometimes I found that UV data will wrong, as you tell me before, I think buffer may be collapse!

But Why UV data collapse? So I guess may be buffer not enough.

Is it possible?

Can you help me to deal with UV data wrong(sometimes)?

Thanks.
