<p>The FFmpeg rescaler provides a high-level interface to the libswscale
library image conversion utilities. In particular it allows one to perform
image rescaling and pixel format conversion.
</p>

<p>The video scaler supports the following named options.
</p>
<p>Options may be set by specifying -<var>option</var> <var>value</var> in the
FFmpeg tools, with a few API-only exceptions noted below.
For programmatic use, they can be set explicitly in the
<code>SwsContext</code> options or through the <samp>libavutil/opt.h</samp> API.

<p>The libavcodec library provides a generic encoding/decoding framework
and contains multiple decoders and encoders for audio, video and
subtitle streams, and several bitstream filters.
</p>
<p>The shared architecture provides various services ranging from bit
stream I/O to DSP optimizations, and makes it suitable for
implementing robust and fast codecs as well as for experimentation.

<p>The libavutil library is a utility library to aid portable
multimedia programming. It contains safe portable string functions,
random number generators, data structures, additional mathematics
functions, cryptography and multimedia related functionality (like
enumerations for pixel and sample formats). It is not a library for
code needed by both libavcodec and libavformat.
</p>
<p>The goals for this library is to be:
</p>
<dl compact="compact">
<dt><span><strong>Modular</strong></span></dt>
<dd><p>It should have few interdependencies and the possibility of disabling individual
parts during <code>./configure</code>.
</p>
</dd>
<dt><span><strong>Small</strong></span></dt>
<dd><p>Both sources and objects should be small.
</p>
</dd>
<dt><span><strong>Efficient</strong></span></dt>
<dd><p>It should have low CPU and memory usage.
</p>
</dd>
<dt><span><strong>Useful</strong></span></dt>
<dd><p>It should avoid useless features that almost no one needs.

<p>The libswresample library performs highly optimized audio resampling,
rematrixing and sample format conversion operations.
</p>
<p>Specifically, this library performs the following conversions:
</p>
<ul>
<li> <em>Resampling</em>: is the process of changing the audio rate, for
example from a high sample rate of 44100Hz to 8000Hz. Audio
conversion from high to low sample rate is a lossy process. Several
resampling options and algorithms are available.
</li><li> <em>Format conversion</em>: is the process of converting the type of
samples, for example from 16-bit signed samples to unsigned 8-bit or
float samples. It also handles packing conversion, when passing from
packed layout (all samples belonging to distinct channels interleaved
in the same buffer), to planar layout (all samples belonging to the
same channel stored in a dedicated buffer or &quot;plane&quot;).
</li><li> <em>Rematrixing</em>: is the process of changing the channel layout, for
example from stereo to mono. When the input channels cannot be mapped
to the output streams, the process is lossy, since it involves
different gain factors and mixing.
</li></ul>
<p>Various other audio conversions (e.g. stretching and padding) are
enabled through dedicated options.

<p>The libswscale library performs highly optimized image scaling and
colorspace and pixel format conversion operations.
</p>
<p>Specifically, this library performs the following conversions:
</p>
<ul>
<li> <em>Rescaling</em>: is the process of changing the video size. Several
rescaling options and algorithms are available. This is usually a
lossy process.
</li><li> <em>Pixel format conversion</em>: is the process of converting the image
format and colorspace of the image, for example from planar YUV420P to
RGB24 packed. It also handles packing conversion, that is converts
from packed layout (all pixels belonging to distinct planes
interleaved in the same buffer), to planar layout (all samples
belonging to the same plane stored in a dedicated buffer or &quot;plane&quot;).
<p>This is usually a lossy process in case the source and destination
colorspaces differ.

* The format negotiated by the graph during configuration can be obtained
* using the accessor functions:
* - av_buffersink_get_time_base(),
* - av_buffersink_get_format(),
* - av_buffersink_get_frame_rate(),

* - av_buffersink_get_ch_layout(),
* - av_buffersink_get_sample_rate().
*
* The layout returned by av_buffersink_get_ch_layout() must de uninitialized
* by the caller.
*
* The format can be constrained by setting options, using av_opt_set() and
* related functions with the AV_OPT_SEARCH_CHILDREN flag.
* - pix_fmts (int list),
* - sample_fmts (int list),
* - sample_rates (int list),
* - ch_layouts (string),
* - channel_counts (int list),

* Most of these options are of type binary, and should be set using
* av_opt_set_int_list() or av_opt_set_bin(). If they are not set, all
* corresponding formats are accepted.
*
* As a special case, if ch_layouts is not set, all valid channel layouts are
