DM368 resizer

NO. VPFE doesnt support conversion from yuv420 to yuv422. Otherway is possible. yuv422 to yuv420 semi is possible in RESIZER.

Hi,Nagabhushana

DM368 can scale-up YUV422 to YUV444 and then convert to RGB for output. Can DM368 scale-up YUV420 to YUV444？

Could I get the intermediate data,YUV444?

Regards,

Are you talking about VPBE?

Again, are you referring to VPBE?

I am doubtfull about this. Please refer to dm36x VPBE/VPFE user guide. I believe through VPBE you cant get the intermediate buffers. You can only display.

Hi,Nagabhushana

My fault! I should make myself clear.

I am talking about VPFE. VPFE can read data from SDRAM via IPIPEIF and output data to SDRAM via IPIPE/RSZ .

So I think if I input YUV420 planar data, could I get YUV422(interleaved or other format) data?

My answer is 'NO'.

Hi,Nagabhushana

Oh...thanks anyway!

By the way, is there any way I could get YUV422 from DM368/DM365, while I input YUV420?

And not display, I want YUV422 data is in SDRAM.

Thanks and regards.

I am afraid there is no way.

Can you please tell me why you want this? If you can tell me exactly what you are looking for, I might suggest you some other way of achieving your goals.

For example, you can display yuv420semi(NV12) using VPBE. You don't need to convert yuv420semi to yuv422 if you are considering disaplying frames using VPBE.

Tell us about your project requirements.

Hi,Nagabhushana

That's great!

I use DM368/DM365 DVSDK viddec to decode H.264, and so its output format is YUV420semi(I have tried to find a way to get YUV422 output, but failed),

however, my DA(not VPBE display) supports YUV422 only, so I need convert YUV420 to YUV422(Further,I have to consider throughout). This's the problem!

'IF'  DVSDK viddec support YUV422 output, then, I have no problem! >_<

Thanks and regards.

What is DA?

Hi,Nagabhushana

"DA", I mean DAC,receive YUV422 data and output CVBS analog signal, use for displaying.

Thanks and regards.

Hi,

I am using DM368EVM with DVSDK4. I want to convert Mpeg4dec output (YUV420 semi planer and YUV422 interleaved) to RGB, to display over LCD. Is it possible using DM368EVM.
