The check and the corresponding message in do_video_out() are
unnecessary in the libavfilter path, as a similar check and message
are performed within the buffer source.
Implement lazy initialization of the image resample context, so that
the initialization code does not need to be duplicated.
Also manage the case in which resample/size change mid-stream. For
each packet the code computes if resampling is needed.
Previously the resample check was done only at the initialization, in
case size/format changed and no resample was detected at the init
stage ffmpeg was silently exiting.
avfilter_copy_frame_props() avoids code duplication and increases
robustness.
The added files libavfilter/avcodec.[ch] are used for containing
utilities useful for gluing togheter libavfilter and libavcodec.

The problem with url_exist() is that it tries to open a resource in
RDONLY mode. If the file is a FIFO and there is already a reading
client, the open() call will hang.
By using avio_check() with access mode of 0, the second reading
process will check if the file exists without attempting to open it,
thus avoiding the lock.

Redesign the way -aspect option is handled. This is done by making
ffmpeg read the sample aspect ratio set in the corresponding input
stream by default, and overriding it using the value specified by
-aspect.
If the output display aspect ratio is specified with -aspect, it is
set at the end of the filterchain, thus overriding the value set by
filters in the filterchain.
This implementation is more robust, since does not modify the
filterchain description (which was creating potential syntax errors).
Prefer parse_number_or_die() over atoi()/atol() parsing for the options:
-pass, -top, -vc, and -qscale.

Currently bits_per_raw_sample is exposed as an AVCodecContext option.
The option is not very useful, because ffmpeg 1) overwrites it with

the video is resampled.
This patch adds the -bits_per_raw sample option to FFmpeg, and
caches the value like is done for the -pix_fmt option.

AVFilterLink.srcpic -> AVFilterLink.src_buf
AVFilterLink.cur_pic -> AVFilterLink.cur_buf
AVFilterLink.outpic -> AVFilterLink.out_buf
The new names are more generic and more consistent, since the struct
they contain, which was named AVFilterPicRef, has been renamed to
AVFilterBufferRef.

The struct is going to be used for storing audio buffer references as
well, and the new name is more generic.

in favor of the newly added corresponding functions
av_parse_video_size() and av_parse_video_rate() defined in
libavcore/parseutils.h.
This change also adds a linking-time dependency of libavcodec and of
libavfilter on libavcore.

BeOS support has been broken for many years and the "maintainer" of the port
has not reacted to countless requests to get the port fixed.

This fixes a regression on Windows introduced by r22769 in which the data read
from the file was not properly zero terminated. The file was read as text,
which caused the \r characters to be suppressed. Since the zero termination
happens at the end of the buffer, and there was one byte less read per line,
this caused the remaining space on the buffer to contain random data.

we'd memset() the codec context to zero, thereby setting audio input to U8
and video to YUV420P. For most video encoders, that actually works, but for
most audio codecs, it doesn't. This patch changes defaults to those set by
avcodec_context_get_defaults() and have ffmpeg figure out the optimal encoding
format itself if not set explicitely (as it does for the non-ffserver-cases
also).

ffmpeg.c uses lrintf(), which is missing on some systems. Previously
it picked up the replacement via libavutil/internal.h due to
HAVE_AV_CONFIG_H being erroneously defined.
Moving these replacements to a separate header enables ffmpeg.c to
use them without being exposed to internal interfaces.
This use of a non-public header is justified by the header in question
not being part of the internal interface either. It should rather be
considered as part of the build system, which is shared between the
libraries and the applications.
This header cannot be installed since the tested conditions depend on
the compiler.
