1)When I open url rtsp stream in day light mode - all ok.
2)When I duplicated my rtsp stream into mp4 file at the day light mode - also all ok. I see moving picture and after all I've got normally created file.
3)When I open url rtsp stream at the night (dark image with noise) - all ok - noise is moving, so i see live picture.
4)When I duplicated my rtsp stream into mp4 file at the NIGHT - the picture is freeze but after closing player I've got normally writed file.
So duplicate only affects on the night picture - very strange BUG.
PS
I planned to use libvls in my simple security videosubsystem project - i already integrated it in all parts of my software, but now all my work is garbage, I returns to zero point
