C++ examples about decord HOT 3 OPEN

One issue I'm still trying to understand is where the source of the performance boost over OpenCV comes from. I assume most of the code responsible for the speed increase is written in C++ with a python wrapper around it for easier usability. OpenCV video also has the option to use FFMPEG.

If the performance boost is due to an algorithmic design/implementation, then it would probably be easier and more beneficial to the community to add the decord video reader to OpenCV (unless there are implementation decisions in OpenCV that prevent that), which already has a python wrapper. Plus you don't have to maintain a separate project.

Unfortunately the focus is not on c++ API part, but here's an tiny example c++ app for deploying video based model to Jetson: https://github.com/zhreshold/cvpr2020-videomodeling-deployment/tree/master/tvm_deploy

Hope that helps. In the meantime if you can comment or provide helping hand in c++ dev part I will be more than happy to discuss.

I should mention that I think this is great work. Whenever I see comparisons made regarding a specific feature (in this case video loading/access) to tools like OpenCV that show a clear improvement, I like to see that work get folded back into the original tool.
