Further testing the problem. It seems that when c2play is started from the terminal and not remotely through SSH, the blank screen doesn't occur. This has been done with a small clip resulting in a high loop frequency. Will test some more with a larger clip. What may happen is that c2play somehow cannot output over SSH and craps out?

Update: did more testing with a larger file and no problems occur when started from the local terminal.

This is most likely the console screen saver. The fbdev version attempts to disable it:

c2play/src/UI/Fbdev/FbdevAmlWindow.h

Lines 64 to 77 in 534cac8

 // Set graphics mode 

 int ttyfd = open("/dev/tty0", O_RDWR); 

 if (ttyfd < 0) 

 { 

 printf("Could not open /dev/tty0\n"); 

 } 

 else 

 { 

 int ret = ioctl(ttyfd, KDSETMODE, KD_GRAPHICS); 

 if (ret < 0) 

 throw Exception("KDSETMODE failed."); 

 close(ttyfd); 

 }

This may be failing if running over SSH. The console screen save can also be disabled on the kernel command line.
