1) To ensure that the *.mpeg4 file that the DM355 creates is good, try
playing it back in VLC - yes, VLC can play back these files.

2) Also, you can use a program called YUVTools to inspect the YUV file
that you created to ensure it's in the proper UVYV format that output
display requires.

3) Try to use gdb to step through your application (the main, or ctrl
thread) to see where it is quiting

4) Write a barebones simple application that is essentially a stripped
down version of the display thread. This should just open the display
driver (/dev/fb/0), memcpy a 320x240 image into memory and flip display
buffers (panning) and see if it comes on your screen.
