------- Comment #3 from Wim Taymans  2009-03-16 11:59 UTC -------
this driver seems buggy:

2src_calls.c:180:gst_v4l2_buffer_new:   input:     0


note how MMAP offset = 2882400000 (abcdef00 in hex!?) 
also note how length = 16777216 (1000000 in hex!?)

the frame size of 152064 seems to be correct for this resolution and 
video format.

Maybe this is caused by libv4l2?
