MediaInfo shows many videos files containing multiple video streams (Please see the bottom part of the post).
How such kind of videos are created?
If multiple video streams, then why it can only play back one video in video player?
Why in GraphEdit of DirectShow, such files open multiple video windows (ActiveMovie) but only one of them showing content, the rest are all blank?
Is it correct just encode whichever can be encoded with such file without concerns of the rest blank video streams?
Thanks!
