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.

-same_quant is not designed to convert between quantizer scales, AFAIK.

Add example using concat protocol.

Add a new option 'rtmp_flush_interval' that allows specifying the
number of packets to write before sending it off as a HTTP request.

This is mostly relevant for RTMPT - for plain RTMP, it only controls
how often we check the socket for incoming packets, which shouldn't
affect the performance in any noticeable way.

This adds two protocols, but one of them is an internal implementation
detail just used as an abstraction layer/generalization in the code. The
RTMPT protocol implementation uses rtmphttp:// as an alternative to the
tcp:// protocol. This allows moving most of the lower level logic out
from the higher level generic rtmp code.

Add atempo audio filter for adjusting audio tempo without affecting
pitch. This filter implements WSOLA algorithm with fast cross

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.

These functions are modeled after the corresponding utilities in
libavutil/timestamp.h.

Allow using connection parameters in order to append arbitrary
AMF data like "B:1 S:authMe O:1 NN:code:1.23 NS:flag:ok O:0" to the
Connect message. You can pass these parameters through the -rtmp_conn
option.

The rounding was wrong due to incorrect ue of floats,
changed to rationals and av_rescale.

The results were not properly passed to SDL.

The current flat arguments syntax is not easily extensible
due to sws_param possibly containing commas.
This is also consistent with abuffersrc.

The function was introduced in 4d6a8a2bdb and is not used anymore
outside avfilter.c.

This avoids to pollute the public API with an apparently unnecessary
function. The function was introduced a few days ago, so removing it from
the public API should do no much harm.

The filtering_audio.c example needs to be updated for the new
"abuffer" filter args.

Based on the shotdetect algorithm (http://shotdetect.nonutc.fr/ by Johan
MATHE johan.mathe tremplin-utc.net).

The function is modelled after av_default_item_name(), and will print the
name of the instance filter if defined, otherwise the name of the filter.

This allows to show the instance name in the log, which is useful when
debugging complex filter graphs.
