This shouldn't go in commit message, consider using "---8<---"
scissors marker for annotation to mailing list in the beginning of
email, before actual commit message. BTW in this case empty commit
message is fine in my opinion, also maintainers can come up with
something.

Backslash is not needed, you can just break the line. Spacing is not
needed too, i think. I am not sure what is the position of bitwise OR
operator more following the style - at the new line, or on first line.

In this function, you have set ret = 0 in the beginning, and then set
to AVERROR(ENOMEM) literally everywhere. You can save the lines by
setting it to AVERROR(ENOMEM) at the beginning, i think. However,
that's not that important

Second line has one char less of spacing than everywhere else in the patch.

Comment not indented.
I have tested this patch, both with "--enable-libfribidi" and without.
Compiles without warnings and works as expected.
LGTM. Especially I like the fact that it handles both cases
(left-to-right and right-to-left) by itself, without extra parameters
from user.
