question about Dual stream encoding

OYE

Dear all:

I am using DVRRDK3.0 with DM8168EVM.

I create a chain to archive dual stream and JPEG encoding.Because there is no capture module,I used NullSrcLink.The following is my chain,and is runing normally.

SRC

---------------------------- Dup -------------------------------

| | |

| | sc

| | |

| | nsf

| | |

----------------------------merge -------------------------------

ipcOutVpss

ipcInVideo

enc

ipcBitsOutVideo

ipcBitsInHost

I have these three streams saved to 3 files.

When I set the srcPrm.tilerEnable = TRUE, I was able to get the desired results,.

And, When I set the srcPrm.tilerEnable = FALSE, the result is not correct.

I want to know why this is.

Can you confirm tilerEnable = TRUE is working and tilerEnable = FALSE is not working.NullSrc doesn't really support tiler so tilerEnable in nullSrc will not give correct data.

For both tiler enable and disable case, what is the configuration SclrLink tilerEnable ? Scaler link has a bug where it would set pitch wrongly if input is tiler but output is non-tiled. This bug Is fixed in DVR RDK 4.0

Hi Badri,

Thanks for you reply.

Probably because I did not have capture module, so the results look not very clear.

I have not very clear about tiler module, can you give me some introduce?

Thanks!
