5af7daabc4 Mark AVFilterPad[] compound literals as const.
GCC 4.6.2 at least still seems to fail to put them in .rodata though,
see also http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37303

2b550beb22 vf_lut: add plane validity check in draw_slice()
The value for inpic->data[plane] with plane >=4 is undefined, and it
will contain in general random data. This change adds a check for
exiting the loop when plane reaches the value 4.

Fix crash (occurring for example with: format=rgba,lut).
