multiview on same activity using vlc
Posted: 27 Feb 2014 16:07
I would know if is possible to use two surface in same layout and view each at same time. In future I would a grid-view of videoview, but each videoview using vlc.
I modify this sample (https://bitbucket.org/edwardcw/libvlc-a ... ?at=master) usign fragment.
The result is that I see only one video...How can I solve ?
this is my code
this is my layout
this is single fragment layout
EDIT:
From logcat I not see important error, but I think that there are rendering problems for android UIThread
