Hi, we use RDK4.0, DM8168.

Does the SwMs Link can realize multi-channel video overlay?

I don't find any information or code for this. If the SwMs Link can not realize, is there another method?

Thanks

Hi, Badri.

Just like the following picture:

Mutich-video is overlay on the one screen.

Yes this is possible. You will have to create the layout with required swmsPrm.layoutPrm such that the windows overlap. You should take care of couple of things:

1. Use only one scaler in Swms.

2. The window that you want visible (upper layer) should have higher window number compared to lower layer

How can I obtain RDK4.0?

Should I pay for RDK4.0?

0 Badri Narayanan over 12 years ago in reply to huayi feng

Contact TI FAE / TI Sales Contact for RDK 4.0 release. You don't have to pay for it.You require an NDA with TI to get access to RDK which I assume you already have as you are using RDK 3.0

Hi,Badri ! If I want to use two scaler,Is thers a way on dvrrdk 4.0 ? One scaler not enough for us. thanks!

0 Badri Narayanan over 11 years ago in reply to sheng xie

You can use 2 scaler in swms .This is already supported .Refer multich_vdec_vdis.c usecase where multiple scalers are used. You cant use multiple scalers if you are using PIP layout where one video window is overlayed over another video window than you can use only one scaler.

Thanks，Badri.

I need to use PIP layout and one scaler cant meet our needs.one scale supports only 18 channel but I need 24.

so is any way solve my problem? why two scaler cant work together?

0 Badri Narayanan over 11 years ago in reply to sheng xie

TI__Guru 59700 points

Are you sure you have 24 windows in PIP layout. You cant use multiple scalers _only_ in PIP layout. When yu switch to some other layout you canuse multiple scalers. The swms has API to dynamically map scaler to input channel.

Two scalers cannot be used in PIP because if two scalers are used the ordering of one window above the other window cannot be achieved.

Thanks,Badri.

I thought of another way. Can I use two mosaic do PIP.each mosaic bind to a scaler. Two mosaic simultaneously output to a display. I want to know if display could accept two mosaic?

0 Badri Narayanan over 11 years ago in reply to sheng xie

I don't understand your suggestion.Display cannot display 2 images simultaneously.
