ISO C requires at least one argument in the place of the ellipsis in a
variadic macro. In particular, under -pedantic, this triggers the
warning -Wgnu-zero-variadic-macro-arguments on clang 3.7.

Only set pict if we got a valid rect.
Signed-off-by: Marton Balint <cus@passwd.hu>

Current code segfaults since the deprecation of AVSubtitleRect.pict because it
freed/realloced AVSubtitleRect.pict.data by itself.

The new code stores the generated YUVA AVSubtitle rectangles in their own
struct and keeps the original AVSubtitle structure untouched, because
overwriting it is considered invalid API usage.

GCC (and Clang) have this useful warning that is not enabled by -Wall or
-Wextra. This will ensure that issues like those fixed in
4da52e36
will trigger warnings.

mp3 packets all have the same duration and number of samples
if their duration indicated in the container varies then thats an
indication that they are not 1 mp3 packet each.
If this autodetection fails for some case then please contact us
and provide a testcase.

Fixes Ticket4938

This does not trigger any warnings, but adds robustness.

It is well known that fabs and fabsf are at least as fast and sometimes
faster than the FFABS macro, at least on the gcc+glibc combination.
For instance, see the reference:
http://patchwork.sourceware.org/patch/6735/.
This was a patch to glibc in order to remove their usages of a macro.

The reason essentially boils down to fabs using the __builtin_fabs of
the compiler, while FFABS needs to infer to not use a branch and to
simply change the sign bit. Usually the inference works, but sometimes
it does not. This may be easily checked by looking at the asm.

This also has the added benefit of reducing macro usage, which has
problems with side-effects.

Note that avcodec is not handled here, as it is huge and
most things there are integer arithmetic anyway.

Tested with FATE.
