Hi Lenard,

When you use multiple streams of video in this demo, you can specify the batch size which will take all the frames and perform inference on each frame at the same time.

For example, using the argument -bs x (where x is the number of video streams), the demo will grab a frame from each video stream and perform inference on each frame all at once.

I hope this information is helpful, please let me know if you have any further questions.


Best Regards,

Sahira

Hi sahira,

So which mean that this demo will grab all possible video stream and perform to each difference frames. right?

I have another question for this demo: because of multi cameras, may i know that each camera need their movidius neural compute stick or multi cameras can share by one movidius neural conpute stick?

Thank you.

Hi Lenard, 

Yes, you are correct.

And you can use 1 NCS2 to perform inference on multiple video streams. You can use multiple NCS2 if you would like to speed up inferencing, but it will work with just one.
