Failed to run "End to end video analytics end2end_video_analytics_ie Demo" on Visual Studio 2015


Hello, I've been trying to get running under Windows 10 under Visual Studio 10. I managed to get it to compile and run. But I found out it's failing to open "cars_768x768.h264". Is the opencv under openvino folder sufficient enought to run the demo? Is there anywhere I can find steps to rebuilt opencv under the openvino folder?

Thank you.


P.S I just realized I might have double-posted. I have no idea how to delete it since I can't see it. Sorry for the trouble.

Dear zero, heisenburgzero

I believe i have answered this question in the above-referenced forum post.

Thanks for using OpenVino !

Dear G, Shanmuga vadivelu,

Are you on 2019R1.1 ? I have no problem running end2end_video_analytics_ie.exe on Windows 10. (OS should not matter).  Please follow the 

end to end demo doc

end to end ubuntu instructions

One of the steps is to use to download the required model. And instructions are given in the first doc above regarding how to convert the model into Model Optimizer Generated IR.

If you follow these instructions carefully and you are using OpenVino 2019R1.1 you should meet with success. Below are my results:

Thanks for your help Shubha

I got the result as expected. I would like to know, how can I implement OpenVINO in my own custom object detection using Tensorflow?, as I have trained model(Faster R-CNN Inception_v2_COCO)

Dear G, Shanmuga vadivelu,

First you would follow Tensorflow Training Custom Object Detector, then after you've obtained a trained model, you'd convert it using Model Optimizer Tensorflow Object Detection API instructions .

Finally you'd run inference using as a base one of our Object Detection samples, which we offer in both Python and C++.

Hope it helps,
