[Libav-user] Can we get two live streams with one USB camera (C++)

[Wenpeng Zhou]

Hi,

I am wondering if we can get two live streams with one USB camera.
So, we can stream one of live streams, and save the other stream frames to
memory buffer that has a fixed length. for example, the buffer can contain
200 frames. at some point, I can save these 200 frames to an AVI file.

I will implement with C++ windows, please give me some code example.

Thanks in advance!
