The "loop" option is used in several demuxers (like img2dec) and muxers, using the same name in ffmpeg_opt
breaks them. Feel free to revert this and replace by any other solution or rename both as preferred
This is just as a quick fix to avoid the regression with existing command lines and to have both named
the same (which does not work)

Example:
./ffmpeg -loop 1 -i fate-suite/png1/lena-rgb24.png -t 1 test.avi
will produce 25 frames with the img2dec loop but only 1 frame at 25fps with the ffmpeg loop option

This uses the av_warn_unused_result attribute liberally to catch some forms of improper
usage of functions defined in avfilter/formats.h.

Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM).
This propagates the return values.

All of these were found by using av_warn_unused_result, demonstrating its utility.

Tested with FATE. I am least sure of the changes to avfilter/filtergraph,
since I don't know what/how reduce_format is intended to behave and how it should
react to errors.

This fixes access to Grandstream cameras, which return 401 otherwise.
VLC sends Authorization: header with spaces between parameters, and it

Work on the AVFrame references directly.

Instead of setting up a flipped/swapped "view" on the pictures,
flip/swap them when returning decoded frames to the API user.

Rather than copying data buffers around, allocate a proper frame, and
use the standard AVFrame functions. This effectively makes the decoder
capable of direct rendering.

Partially fixes Ticket 4727.

-duration is not a safe expression, since duration can be INT_MIN.
One might ask how it can become INT_MIN.
Although it is true that line 2574 is no longer reached with INT_MIN due
to commit 053e80f6 (which fixed another
integer overflow issue), mov_update_dts_shift is called on line 3549 as
well, right after a read of untrusted data.
One can do the fix locally there, but that function is already a huge
mess. Changing mov_update_dts_shift is likely better.

This changes duration to INT_MIN + 1 in such cases. This should not make any
practical difference since such streams are anyway fuzzer files.

Tested with FATE.

When scaling only a slice of a frame the output was written always
in the first lines leaving the rest of the frame black.

This patch fixes build of AAC encoder optimized for mips that was broken due
 to some changes in generic code that were not propagated to the optimized code.

Also, some functions in the optimized code are basically duplicate of functions
 from generic code. Since they do not bring enough improvement to the optimized
 code to justify their existence, they are removed (which improves
 maintainability of the optimized code).

Optimizations disabled in 97437bd1 are enabled again.

These aren't quite as helpful as the ones in 8bpp, since over there,
we can use pmulhrsw, but here the coefficients have too many bits to
be able to take advantage of pmulhrsw. However, we can still skip
cols for which all coefs are 0, and instead just zero the input data
for the row itx. This helps a few % on overall decoding speed.
