TDA2PXEVM: output is rotating, for 1200X400 resolution

Part Number: TDA2PXEVM

Hi all,

I am using TDA2PX and visionsdk 3.07 and hlos(linux). I have following usecase :

NullSource (A15) -> Decode -> VPE -> Sync -> Alg_1(DSP1) -> SgxFrmcpy (A15) -> Display_LCD

in which I have input of 1280 X 720 to nullsource link. The input is decoded and  data format is set then it is given to Alg_1 via sync (4 inputs) . The Alg_1 processes and produced the output of 1200X400 .

the output is mapped on bowl and converted to 1280 X 720 resolution using sgxFrmCpy link and displayed . This is happening correctly.

However, for optimization I have put some part of processing pf Alg_1 on DSP2 as well and following is my updated usecase.

NullSource (A15) -> Decode -> VPE -> Sync -> Dup -> Alg_11 (DSP1) -> Merge
 
Dup -> Alg_12 (DSP2) -> Merge

Merge -> Sync_1-> Alg_Add (EVE1) -> SgxFrmcpy (A15) -> Display_LCD

Here, Alg_Add is used to add the output of both the DSPs which is 1200*400 YUV422I each .

But, after modification I observed that the output is rotating in particular order. I checked the width, pitch and height in every plugin and its correct.

what can be the issue for this resolution as for 960*320 resolution this issue is not reproducing.

Regards,
Megha.
