Subject: I have some questions about DSS.
I am trying to draw 720P streamming images decoded on LCD.
I really wonder about that.
In case of OMAP34XX, only video1 and video2 layer support color space conversion, scaling, rotation.
I think that ways using these features are like below.
[Hiremath, Vaibhav] Rotation is independent on plane, we are supporting rotation through VRFB.
1. Application -> video1 or 2 device node -> V4L2 Interface -> DSS Library -> LCD Panel or Digital output.
2. Application -> fb1 or 2 device node -> omafb driver -> DSS Library -> LCD Panel or Digital output.
[Hiremath, Vaibhav] Both the methods are working fine, at-least I have tested both.
Are all of the 1 and 2 case possible to draw 720P streamming images on LCD Panel in real-time ?
If the case of 1 is impossible, why impossible, and what is the reason implementing like case 2 ?
If possible, What is the way better ?
[Hiremath, Vaibhav]For streaming kind of application I would suggest you to use V4L2 framework.
Could you please tell me you know and you think ?
Thank you,
