This usually calls for an enum. Something like (off the top of my
head):
enum AlignMode {
ALIGN_MODE_NONE,
ALIGN_MODE_COL,
ALIGN_MODE_ROW,
};
{ "align", "alignment mode", OFFSET(align), AV_OPT_TYPE_INT, { .i64 =
ALIGN_MODE_COL }, ALIGN_MODE_NONE, ALIGN_MODE_ROW, E, "align" },
{ "none", NULL, 0, AV_OPT_TYPE_CONST, { .i64 = ALIGN_MODE_NONE },
INT_MIN, INT_MAX, E, "align" },
{ "COL", NULL, 0, AV_OPT_TYPE_CONST, { .i64 = ALIGN_MODE_COL },
INT_MIN, INT_MAX, E, "align" },
{ "ROW", NULL, 0, AV_OPT_TYPE_CONST, { .i64 = ALIGN_MODE_ROW },
INT_MIN, INT_MAX, E, "align" },
[...]
(Or as option enums, call them "col" and "row" perhaps.)

If so, I think you should add a warning and tell the user that the code
is falling back to COL mode.

Can't be reached if you use the option system as above, add a warning
perhaps.
