Hi experts,

Could you give some hints about the question below ?

1. Does it support multiple video composition, like the mosaic link in DM8148, 8168.., etc ?

2. If yes, How many channels of videos it supports ?

HI Team
I am also interested regarding the mosaic support and omx_videomixer(DM8168 EZSDK) like feature.
Is it supported in Processor SDK(Linux) with AM5728?

And does the SDK and hardware support line/pixel multiplexed video?

AM57x proc SDK support wayland windows manager. Wayland underneath handles the video compostion using SGX 544 and DSS IP. DSS IP alone can also be used for compostion of upto three planes (depending upon the number of display used) using DRM APIs. SGX can handle more number of channels. There is no mosiac_link/video_mixer type function available today on proc SDK.

Hi Manisha

I mean to say line multiplexed video capture support. Is it available?

Also i have downloaded ti-processor-sdk-linux-am57xx-evm-02.00.01.07-Linux and installed it on my ubuntu 14.04 system. Can you please tell me where is the wayland windows manager code located??

What is the difference between the SDK that i downloaded from http://software-dl.ti.com/processor-sw/esd/PROCESSOR-SDK-LINUX-AM57X/latest/index_FDS.html as compare to using MACHINE=am57xx-evm bitbake arago-core-tisdk-image?

Till now i have used DVSDK and EZSDK only.
