We are writing an application using generic platform package on embedded linux.
It is required to display the exact same content to two devices simultaneously. One is local LCD and another is HDMI.
Our board supplier, unfortunately, tried to display one frame buffer to two devices at lower level but failed to reach the goal.
So we are trying to find some other ways.
As far as I have seen, the following issue is very similar to ours, but it could be applied for OpenGL ES 2.0 only.
Is it possible to display to two devices using generic platform package in the same way as above?
The frame buffers are mapping to "/dev/fb0" for local LCD and "/dev/fb1" for HDMI respectively.
