Prevents DPB from filling up with damaged input.

There is no point in clearing reference explicitly, since that will be
done as a part of ff_h264_unref_picture() right below.

This partially reverts cf70ba37, since
it didn't take into account when rotation is 0, but there is another
valid operation (eg. translation) in the matrix.

This improves motion estimation and avoids using uninitialized data
for resolutions that aren't a multiple of 16.

Prior to d2a25c40, the edges used to be initialized so that encoding
was deterministic, but after that commit it started using uninitialized
data (for non multiple of 16 resolutions).

libopenh264enc: Remove a workaround for silencing warnings about unused variables in the OpenH264 header

The 1.3 release branch of OpenH264 (as well as the master branch)
have been updated so that GCC no longer warns about this variable
as being unused.

This goto wasn't necessary originally, but it should have been

This fixes sending chunked packets (packets larger than the output
chunk size, which often can be e.g. 4096 bytes) with a timestamp delta
(or absolute timstamp, if it's a timestamp step backwards, or the
first packet of the stream) larger than 0xffffffff.

The RTMP spec explicitly says (in section 5.3.1.3.) that packets of
type 3 (continuation packets) should include this field, if the
previous non-continuation packet had it included.

The receiving code handles these packets correctly.

In v2.2, the picture type is not a zero-terminated string, but has a
constant size of 3 bytes.

Some of them are not immediately obvious.

Those functions should not ever modify it.

Move the lavc/imgconvert functions and rename them as follows:
  avpicture_get_size -> av_image_get_buffer_size()
  avpicture_fill     -> av_image_fill_arrays()
  avpicture_layout   -> av_image_copy_to_buffer()

The new functions have an align parameter, which allows to define the
linesize alignment assumed in the buffer (which is set or read).

The names of the functions are consistent with the lavu/samples API
(av_samples_get_buffer_size(), av_samples_fill_arrays()).

A redundant check has been dropped from av_image_fill_arrays().

When the display matrix is not the identity one, but the rotation angle
is zero, there is no need to update the sample aspect ratio.

Otherwise, it is possible to obtain negative values which interferes
with transcoding in later stages. This kind of behaviour is reproducible
on mov files with "major_brand: MSNV".

The latest version added support for a new option for enabling
a signal level limiter, which adds some extra delay. In fdk-aac, this
is enabled by default, but disable it by default here since we'd rather
have zero-delay decoding.
