give a example like this,  DEI have two input port, have four output port,  outport channel 0 and channel 2 connect to NF component, dei output channel 1 and channel 3 are connect to SCALE component. the output port of NF component are connect to ENC0 and ENC1.

The DEI component in EZSDK does not have two input port and two output ports.

The DEI component has ONE input and TWO output ports.
 You could use two DEI components.

What is your use case I understand that you have describe is an example.

Margarita, thank you for your reply!

but there are only two dei component .my problem is that I have two 1080P yuyv input, I want to encode these two 1080P yuyv buffer to  H264 with resolution 704 * 576. And I want to scale 1080yuyv  to resultion 352* 288 yuyv and 1024*768 yuyv. how should I do?

You want to archive dual capture with OMX capture-encode demo in EZSDK?

Hi, Margarita

yes, I want to dual capture and encode them, but also I want to sclae the streams and mixture the source, I then encode the mixture video.

HI, Margarita!

Thank you for your reply.But now I have solve the problem of capture, now my problem is that I want to encode the capture video to 704*576 h264 stream. and I also want to mixture the video, and encode the mixture video . The graph is like this.

                        (yuyv)

yuyv------dei-----------nf --------------------scale------------

                   (nv12)  ----------encode                                               edma copy ------------dei---------nf----encode

yuyv------dei-----------nf-------------------scale-----------                                                  (nv12)  -------encode

                    (nv12) --------encode

HI, 

I have an another question, scale component and nf component support that one handle per multi channel,what is mean? It is that the handle have multi input and multi output?how can I use this feature?

HI， I have another question, It is that my process is crashing, so the  memory is not delete,and donot call omx_unit(), 

how I can reset the co-cpu state, and restart my program.

Hello,

I would recommend you to check here about the components :

http://processors.wiki.ti.com/index.php/OpenMax_Development_Guide#OpenMax_Components

You could check also the OMX user guide (ezsdk/component-sources/omx_05_02_00_48)

In the OMX user guide check the tear down sequence.

Hi,Can you give me an example that use nf to support multi channel?I don't know what is mean and i can not found example .Thank you very much!

Hello,

In latest EZSDK version 5.05.02 we have an example where the noise filter is used. In display_decode you could find it. We are using there the noise filter to convert YUV422 to YUV420. Keep in mind that the width, height and pitch should be multiple of 32.
