libVLC 2.1.x opens 2 windows on a stream with 2 video tracks inside
Posted: 11 Oct 2017 13:43
Hi all,
I use libVLC in a Qt application, using an embedded widget to show content there. This works fine. Now I've got a video stream with 2 video tracks inside. libVLC opens one video embedded as needed, but opens an additional window for the second video stream. I found a command line option "--preferred-resolution=[lines]" and the description sounds promising, but also if I use this, the 2nd video window is opened. Is there another way to force the usage of only one video track?
Here is the media info of the stream:
Thanks in advance,
Jörg
