Hi, I saw lots of use of m_scenes.get_object_by_dupli_name in this tutorial

However, I do not see why we want to duplicate an object and work on it. Could you elaborate on the usage of this method? Thank you so much!!!

Hi!

First of all, I'd like to thank you for the great work. Blend4web helps our project a lot. Hope you could keep up with the good work!

Recently, our project needs to deploy video and audio, so I have a look at this great post https://www.blend4web.com/en/article/95/

But when I tried to print the m_tex.play_video("myTexture") method to see whether it works, the console gives me a undefined warning. I put the method in load_cb() method.

I am not sure what is wrong here?

Also, I notice that blend4web separates audio and video, and I need to use the sfx module to play the audio. However, I am confused on how to play the audio of a video I want to play? Should I convert the video into an audio file first, and then play the audio and video together? Or if there is a better way?

Thank you so much!
