'k', 'M', and 'G' are SI (unit) prefixes or metric prefixes,
not 'number postfixes'. Also, the statement regarding binary
prefixes ("powers of 2 are used instead of powers of 10")
might be misinterpreted (1 kB = 10^3 B, but 1 KiB != 2^3 B).

This code spews a multitude of warnings with glibc (unchecked
return values), some of them possibly warranted. Furthermore,
the deamonisation is not suitable for use with typical startup
scripts as it does not provide the PID of the daemon in any way.
Users wishing to run avserver as a daemon can still do so using
start-stop-daemon or equivalent tools.

The options USE_INLINE_TREES, SHOW_DIRECTORIES and HTML_ALIGN_MEMBERS
became obsolete with doxygen 1.8.1 (releaded 2012-05-19). The generated
outpu for older doxygen versions should not change since they were set

The mention of multimedia stream sounds more like multiple
elementary media streams like video and audio multiplexed

If the first argument can be read as a video size, set that output size
in the scale. This allows to specify in a filtergraph scale=qcif or
scale=320x240.
This is not completely safe, for example in case of a typo in the video
size string the first argument will be read as the input width
expression, giving rise to a confusing comment.
They are essential to be able to use the utils without av_malloc()
That is for example use with malloc(), memalign(), some other
private allocation function, on the stack or others.

In addition to the recent tables mess, the AVOption defaults behavior
changed, so an old lavc used with a new lavu will get completely messed
up defaults.
This commit introduces a new AVPacket side data type:
AV_PKT_DATA_STRINGS_METADATA. Its main goal is to provide a way to
transmit the metadata from the AVFilterBufferRef up to the AVFrame. This
is at the moment "only" useful for lavfi input from libavdevice:
lavd/lavfi only outputs packets, and the metadata from the buffer ref
kept in its context needs to be transmitted from the packet to the frame
by the decoders. The buffer ref can be destroyed at any time (along with
the metadata), and a duplication of the AVPacket needs to duplicate the
metadata as well, so the choice of using the side data to store them was
selected.
Making sure lavd/lavfi raises the metadata is useful to allow tools like
ffprobe to access the filters metadata (it is at the moment the only
way); ffprobe will now automatically show the AVFrame metadata in any
customizable output format for users. API users will also be able to
access the AVFrame->metadata pointer the same way ffprobe does
(av_frame_get_metadata).
All the changes are done in this single commit to avoid some memory
leaks: for instances, the changes in lavfi/avcodec.c are meant to
duplicate the metadata from the buffer ref into the AVFrame. Unless we
have an internal way of freeing the AVFrame->metadata automatically, it
will leak in most of the user apps. To fix this problem, we introduce
AVCodecContext->metadata and link avctx->metadata to the current
frame->metadata and free it at each decode frame call (and in the codec
closing callback for the last one). But doing this also means to update
the way the tiff decoder already handles the AVFrame->metadata (it's the
only one decoder with frame metadata at the moment), by making sure it
is not trying to free a pointer already freed by the lavc internals.
The lavfi/avcodec.c buffer ref code is based on an old Thomas Kühnel
work, the rest of the code belongs to the commit author.

Make av_pix_fmt_descriptors table static on next major bump.
Making the table public is dangerous, since the caller has no way to
know how large it actually is. It also prevents adding new fields to
AVPixFmtDescriptor without a major bump.
The current API where the plain size is exposed is not of much
use - in most cases it is allocated dynamically anyway.
If allocated e.g. on the stack via an uint8_t array, there's no
guarantee that the struct's members are aligned properly (unless
the array is overallocated and the opaque pointer within it
manually aligned to some unspecified alignment).
