Re: saDisplay + DM6467 showing black an white image in SD Display
Hi,
Display won't work with YUV 422 Planar sorry it was my mistake.
Your input is 4:2:0 semi planar to VDCE, and output of VDCE will be
4:2:2 semi planar which will be given to display driver and hence
display would be working, as display accepts 4:2:2 semi planar input.

I just made the saDisplay to work.
Its always better to follow some principle like,
Give YUV420 semi planar data to convert YUV422 data
other wise you will get wrong conversion file because when we use Ccv
it always copy the data with image width size
Display always works with YUV422 Planar
Anyway thanks for your detailed description that made me analyse
it properly.

Hi
Deepika,
As per the specs, VPIF cannot display planar YUV422 data. It says it
takes Luma and Chroma data for top and bottom field for interlaced
image and Luma and Chroma data for the Progressive image. Also there is
no separate register even to specify buffer pointer for cb and cr data.
This is also true for the VDCE. Can you please tell me where it says
VPIF can display planar YUV422 images?
Thanks,

Subject: Re: saDisplay + DM6467 showing black an
white image in SD Display
Hi,
DM6467 encode/decode supports 4:2:0 YUV semi
planar mode only
Capture driver supports 4:2:2 YUV semi planar and display supports
4:2:2 semi planar and planar.
VDCE module performs conversion irrespective of planar/semi planar
mode, it does resize and CCV conversion
Assume you perform CCV conversion of 4:2:2 to 4:2:0 than
* If input is 4:2:2 semi planar than output will be 4:2:0 semi planar
* If input is 4:2:2 planar than output will be 4:2:0 planar
Capture and display drivers allocate buffer for 1920x1080 resolution
during initialization. Two buffers are located, one for luma and other
for chroma.
So, Chroma will be at the offset of 1920*1080 irrespective of the
capture resolution. Same is true for the display driver. But this is
the case only for MMAP buffers as MMAP buffers are allocated by the
driver.
Luma and chroma can be arranged together with the ioctl S_FMT. In that
case chroma data will be at the offset of "width*height", where
width/height corresponds to the resolution selected.
One more thing, in case of MMAP buffers, if S_FMT is performed than
Luma and chroma will be aligned together and buffer length would be
still 1920*1080*2 as those buffers are allocated during initialization.
VDCE expects chroma at the offset of "buffer length /2", in that case
also only Y data will appear, as actual chroma data would be at 720*480
offset for NTSC.
Hope this helps you to debug your problem

Deepika

Hi,
Its confusing me..
Let me give your data
In my system, I just decode MPEG-4 Data and get YUV420 on D1
resolution.. Now What I am doing is Just get one Frame of YUV420 data
from decoder (YUV420 = [YY][UU...][V] then
convert that YUV420 to YUV422 using saCCV420_422 and then I use the
converted YUV422 to display unit using saDisplay.
I get Luma data properly out on screen but never get Chroma.
Actually I use Decoder Demo Application which made for HD. I have able
to display the HD Decoded data comes with demo and display it on SD
unit. But when I use my customized decoded on D1 resolution I am not
getting anything on screen. So I want to debug the issue using
saDisplay then update it on applicayion.
I hope you got me in a right way...
Looking forward to fix this issue.

Hello Murali,
DM6467 supports NV16 video format, where image is stored in two

You are right, chroma buffer pointer could also be an problem. Display
driver always expects chroma data at the half of the buffer size.
