TDA4VM: Is there any way to control the switch of a stream in the graph?

Damon@INVO

Part Number: TDA4VM
Other Parts Discussed in Thread: TDA2

Hi TI:

I integrated multiple streams in one graph: PSD/OD/SRV/DVR..Now I want to control the on/off state of one of the streams, just like the Gate link in J6（TDA2） platform.

Is there a kernel like Gate link in the J7 platform? Or is there any way to achieve this?

Hi TI:

Supplementary Instructions:

I want to dynamically control the switch of a certain stream during the running process of the app.

For example：

After app started:

at time_1, I want run 'SemSeg' stream only;

Time_2,,I want run 'PSD' stream only;

Time_2,,I want run 'PSD' and 'VD' stream;

Hi Damon,

No, unfortunately, there is no gate link like feature available in the OpenVX framework. You would have to add it in the framework or at the node level.. Like add a control command in the node, when you want to stop processing and then in process function, just skip processing. Again resume it again on second control command..

Hi Brijesh,

Yep.I tried this and found that: if I just send stop cmd to pre_proc node, it dis stop. But it's downstream nodes will still execute processing instead of blocking.

Form this it seems that I need to add and send stop cmd to every node in this stream(pre-proc/tidl/post-proc), right?

Hi Damon,

Yes, require to add this command to all downstream modules, and whenever you want to change processing, you probably need to start from the last node in that path..

Hi Brijesh,

Thank you!

And I wander will TI consider providing a convenient solution for this requirement in subsequent releases?
