DM365 & IPNC Appro : Capture test problem when YUV422 in HD size in Input

reda38
Expert 1455 points

Hello TI staff,

I had adapted the IPNC application to a VGA YUV422 output camera. Ans aldo the test modules used in moduletest.out. And everything is OK. Including the H264 encoding.

The problem arises now when I try to replace my VGA by an HD720p camera. It output data with the same format YUV422 in 8 bit format.

The camera configuration is OK. The ISIF test (./moduletest.out drv_isif) output YUV422 images which are OK. Now the problem is that I try to pass the image through the resizer A with no resizing (meaning a 1:1 ratio). And there the problem begins.

It looks like that the storage is not proper in the SDRAM. When debugging with messages I have found that the Y end line in memory was 736.

Why having padded the output buffer ? I do not find an explanation in the specifications.

My image is not good, while it seems few data are visible at the beginning of the buffer, quickly it turns out to be noised with bad data, such as noise, of pink color.

It seems also that the bug I had with alg_vidEnc is probably due to this supplementary lines.

Any clue concerning this "bug" ?

Regards

    Hello as a follow up of this issue, I have tried to remove the padding code set by default with the OSA_Align functions. nd it looks like yuv data are proper.

    Still need to get a good viewer to confirm.

    Hi,

    You might want to share your YUV data to see what is going wrong.

     Hello Anshuman, Can I upload a big file on this site ?

    I have checked the converted to YUV420SP format. Transformed in a software the SP to planar format and in the viewer the image is not proper.

    It is a color bar scheme in HD720P. It is well captured in the moduletest drv_isif test.

    It looks like that for HD and VGA the settings do not behave the same.

    Maybe a moduletest drv_resz should be done before

    Best Regards

    Hi Anushman,

     

    I also suffered by the same problem - pink issue -image captured by the av_server

    First I captureed the yuv file(640x480) and i convered into bmp format ,in that i m observing some pink color noise .

    I attached the fie for ur reference

    yuv file - DATA0000.yuv

    bmp   - img.bmp

     

     

    regards,

    Nandha

    Hello nandha, It looks like you got the same problem than me. The first thing to do is to configure your sensor to send a regular test pattern. For me it was a classical color bars. As you can read my comment I have:

    1-removed some osa_align function for Hsize capture (number of horizontal pixel) in the av_server software of IPNC. With that there was no more band of blue data on top (i had different color but i guess it is a good start). There there was no more "header" zone. There were colors bars but with bad colors. This is typical of YUV components swapping.

    2-If Iooked at the YUV data, they were badly ordered. using the moduletest software it looked like it came from the resizer as the isif output image in ram was good. Anyway I had to invert my data in ISIF to get back on my feet.

    Hope this can help.

    Hi reda38,anushman

    Thanks for ur help,

    anyway i removed the strips and pink noises from the image,but i m not getting any color on the image ,getting only black and white image

    plz find the attached  image

    There can be muliple reasons for this kind of image.

    1. If you are using raw data input, the your RGB2YUV matrix etc. are not correct.

    2. You are not getting the UV data captured somehow.

    What exactly is this image? Is this encoded output? Can you please ensure that you dump the output after capture and then share the YUV data so that we can look at it.

    Are you using raw input capture or YUV input capture?

    Regards,

    Hi,

    I m using yuv input capture

    Straming through vlc is perfect , colors also perfect(checked with color bars it is also perfect)

    PFA attached the yuv file

    regards

    Hi,

    1.Firstly how can we configure the sensor to send a regular test pattern as you have said that a classical color bar.Anyway it will only capture what the camera is capturing live.I am working on Appro DM368.Is there any isif setting by which we can configure it to send some color pattern instead of what is captured by the camera.

    Also how can we invert the image output. from the sensor.

    a.design.Also when i am trying to do ./moduletest.out drv_isif i am getting the following output.
