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 ?
