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.

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).

Since an AVFrame now has malloced members (extended_data), it must have
a destructor.

Can be used by DTS-HD, TrueHD and E-AC-3, among others.

C++ does not allow to mix different enums, so e.g. code comparing
ACodecID with CodecID would fail to compile with gcc.

This very evil hack should fix this problem.

This adds a function to retrieve the number of entries in a
dictionary and updates the places directly accessing what should
be an opaque struct to use this new function instead.

Refactoring mmx2/mmxext YASM code with cpuflags will force renames.
So switching to a consistent naming scheme beforehand is sensible.
The name "mmxext" is more official and widespread and also the name
of the CPU flag, as reported e.g. by the Linux kernel.

Useful in cases where a significant analyzeduration is
still needed, while minimizing buffering before output.

An example is processing low-latency streams where all
media types won't necessarily come in if the
analyzeduration is small.

Both function ease allocating large arrays implementing the overflow
check inside it.

This breaks libavfilter ABI.

This function implements a delay using the first available
of the following functions:

- nanosleep()
- usleep()
- Sleep() (Windows)

The conditional #includes in time.c are simplified by including
unistd.h and windows.h whenever they are available rather than
having these lines triggered by specific functions.

This is more consistent with naming in the rest of Libav.

This will allow making AVFilterPad opaque for the calling apps, since
those are the only two fields that can be useful to the users.

Introduce a new function to set binary data through AVOption,
avoiding having to convert the binary data to a string inbetween.

Rationale is the same as for video width/height etc.

This moves the cpu flag parsing code from avconv to avutil so
it can be accessed elsewhere.

This is a new library for audio sample format, channel layout, and sample rate
conversion.

The functions operate on the sample level rather than the byte level and work
with all audio sample formats.

This is required for letting applications to create and destroy
AVFilterInOut structs in a convenient way.

Also, use the new function in the AC-3 encoder.
