small clarification on video window on dm6446

Hello,

Your question is very vague here. Please clarify exactly what you want to see.  VPBE is very flexible. Do you want picture in picture, blending, or side by side display? Please also tell me the resolution requireemnt of each window.

first of all thanks paul

upto now we used osd window to display an image(png or jpeg) or a text . now we have here  to display an image(png or jpeg), text and a video on the same window (video window)  all are side by side .

and another question .....

upto now we have used osd window and video window .when i disable the osd window video colour is looking good .

my question is ......... how do i make the video colour is looking good by enabling the osd window also.

please give replay ........................

i always thankfull to you.

Hi, please keep the same question in the same thread.

What do you mean by "when I disable osd window, video color looks good"? are you seeing video corruption? Whats the overall video resolution?

Are you using VID0 or VID1 to display video currently? Do you have a picture to show the video problem with both OSD and VID window enabled?

thank you paul ....

i have no any images to explain you ...

but i will try to explain you my problem.

first .............. in decode demo that our TI given to us. for executing that ........

we have to give arguments like this to execute      ----> ./decode -v /data/videos/xyz.avi  -o 

if look at the  TV screen you will see that video is looking some dark colour . this is because of osd window is used.

when i use this arguments for the same execution   ---->./decode -v /data/videos/xyz.avi

now if you look at TV screen then you will find that the video is looking better than without osd .

note :here xyz.avi is a video file with us you can use different file name with you.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------

here upto now we used osd window to display image.

and video window to display video.

Display_Attrs           dAttrs     = Display_Attrs_DM6446_DM355_VID_DEFAULT;

and now i want to display both the image and video side by side on the video window.

the resolution is 720 X 560

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------

once again thank you paul .............

please give reply as soon as possible i always thank full for this....................................................

This might be the blending between OSD and VID. Please do a memory dump of all the VPBE registers, only then we can do further investigation.

hi paul thank you for your reply......................

what about the second one ...............

can i display image and video (side by side) on the same video window or not.

if yes how i can handle it .

thank you again

I am really having trouble understanding what you are trying to achieve.

If by that, you meant having both the image & video on VID0 (or VID1) at the same time, first you need to make sure they have the same color space (yuv422). Normally images are RGB color space...

If they are in the same color space, you can put them side by side in the memory (interleave the lines & final line length = line length of video + line lenght of image).

Hi Paul,

             After a long time !

            can you please give some related documents on what we discussed above.

Thanks and Regards,

Y.V.RAMAKRISHNA.
