It currently does the following:
1) get a zeroed audio buffer
2) copy some properties (but not the data) of the input buffer to it
3) pass this buffer to the output filter
This looks useless and is indeed not used by any filters, therefore
delete it.
Make ff_null_filter_samples() (just pass the buffer to the next filter)
the new default.
The string passed to av_vlog() from libx264's X264_log overflows the 512
byte part_size, truncating x264 parameter output. Double this size
and put it in a #define so it only needs to be changed in one place.

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 reverts commit a2b186a188.
The defines were present for several years, removing
them without a version bump may break API.
(Fixes MPlayer compilation.)
To ensure the full range of values is still used, also adjust all uses of this function to loop from 0
instead of 1. This way only 60.00 is added and nothing lost.

-same_quant is not designed to convert between quantizer scales, AFAIK.
Add example using concat protocol.

The unistd.h header is only needed for the close() declaration.
If this header is not available, the close() declaration may be
provided by another header, e.g. io.h.

The only symbol this file uses from unistd.h is isatty(). By
including the header only when this function is used, the file
can be built on systems without unistd.h (which presumably also
lack isatty).

This muxer supports CODEC_ID_SRT with the timestamps in the packet data
and CODEC_ID_TEXT with the timestamps in the packet fields.
Makes -scodec copy work from Matroska.
The list was set to avfilter_all_channel_layouts,
which is really all common channel layouts.
Not setting it leaves an empty list,
which now means really all.
The decoder configuration initializes the sbr mdct, which needs to know about the sample format to properly take the scale factor into account.

Add request_frame() which checks the black duration when the end of the
stream is signalled. Allow to detect black video segments at the end of
the stream.
Note that the reported last black video segment duration is not very
accurate, since we still miss the duration information in the video
buffer.
Address trac ticket #1470.
