+ * @section ffmpeg_versioning Versioning and compatibility
+ *
+ * Each of the FFmpeg libraries contains a version.h header, which defines a
+ * major, minor and micro version number with the
+ * <em>LIBRARYNAME_VERSION_{MAJOR,MINOR,MICRO}</em> macros. The major version
+ * number is incremented with backward incompatible changes - e.g. removing
+ * parts of the public API, reordering public struct members, etc. The minor
+ * version number is incremented for backward compatible API changes or major
+ * new features - e.g. adding a new public function or a new decoder. The micro
+ * version number is incremented for smaller changes that a calling program
+ * might still want to check for - e.g. changing behavior in a previously
+ * unspecified situation.
+ *
+ * FFmpeg guarantees backward API and ABI compatibility for each library as long
+ * as its major version number is unchanged. This means that no public symbols
+ * will be removed or renamed. Types and names of the public struct members and
+ * values of public macros and enums will remain the same (unless they were
+ * explicitly declared as not part of the public API). Documented behavior will
+ * not change.
+ *
+ * In other words, any correct program that works with a given FFmpeg snapshot
+ * should work just as well without any changes with any later snapshot with the
+ * same major versions. This applies to both rebuilding the program against new
+ * FFmpeg versions or to replacing the dynamic FFmpeg libraries that a program
+ * links against.
+ *
+ * However, new public symbols may be added and new members may be appended to
+ * public structs whose size is not part of public ABI (most public structs in
+ * FFmpeg). New macros and enum values may be added. Behavior in undocumented
+ * situations may change slightly (and be documented). All those are accompanied
+ * by an entry in doc/APIchanges and incrementing either the minor or micro
+ * version number.

+ * Buffer to print data progressively
+ *
+ * The string buffer grows as necessary and is always 0-terminated.
+ * The content of the string is never accessed, and thus is
+ * encoding-agnostic and can even hold binary data.
+ *
+ * Small buffers are kept in the structure itself, and thus require no
+ * memory allocation at all (unless the contents of the buffer is needed
+ * after the structure goes out of scope). This is almost as lightweight as
+ * declaring a local "char buf[512]".
+ *
+ * The length of the string can go beyond the allocated size: the buffer is
+ * then truncated, but the functions still keep account of the actual total
+ * length.
+ *
+ * In other words, buf->len can be greater than buf->size and records the
+ * total length of what would have been to the buffer if there had been
+ * enough memory.
+ *
+ * Append operations do not need to be tested for failure: if a memory
+ * allocation fails, data stop being appended to the buffer, but the length
+ * is still updated. This situation can be tested with
+ * av_bprint_is_complete().
+ *
+ * The size_max field determines several possible behaviours:
+ *
+ * size_max = -1 (= UINT_MAX) or any large value will let the buffer be
+ * reallocated as necessary, with an amortized linear cost.
+ *
+ * size_max = 0 prevents writing anything to the buffer: only the total
+ * length is computed. The write operations can then possibly be repeated in
+ * a buffer with exactly the necessary size
+ * (using size_init = size_max = len + 1).
+ *
+ * size_max = 1 is automatically replaced by the exact size available in the

+ * internal buffer is large enough to hold a reasonable paragraph of text,

+ * There are two core objects in this API -- AVBuffer and AVBufferRef. AVBuffer
+ * represents the data buffer itself; it is opaque and not meant to be accessed
+ * by the caller directly, but only through AVBufferRef. However, the caller may
+ * e.g. compare two AVBuffer pointers to check whether two different references
+ * are describing the same data buffer. AVBufferRef represents a single
+ * reference to an AVBuffer and it is the object that may be manipulated by the
+ * caller directly.
+ *
+ * There are two functions provided for creating a new AVBuffer with a single
+ * reference -- av_buffer_alloc() to just allocate a new buffer, and
+ * av_buffer_create() to wrap an existing array in an AVBuffer. From an existing
+ * reference, additional references may be created with av_buffer_ref().
+ * Use av_buffer_unref() to free a reference (this will automatically free the
+ * data once all the references are freed).
+ *
+ * The convention throughout this API and the rest of FFmpeg is such that the
+ * buffer is considered writable if there exists only one reference to it (and
+ * it has not been marked as read-only). The av_buffer_is_writable() function is
+ * provided to check whether this is true and av_buffer_make_writable() will
+ * automatically create a new writable buffer when necessary.
+ * Of course nothing prevents the calling code from violating this convention,
+ * however that is safe only when all the existing references are under its
+ * control.
+ *
+ * @note Referencing and unreferencing the buffers is thread-safe and thus
+ * may be done from multiple threads simultaneously without any need for
+ * additional locking.

+/* Extension: cl_khr_image2D_buffer
+ *
+ * This extension allows a 2D image to be created from a cl_mem buffer without a copy.
+ * The type associated with a 2D image created from a buffer in an OpenCL program is image2d_t.
+ * Both the sampler and sampler-less read_image built-in functions are supported for 2D images
+ * and 2D images created from a buffer.  Similarly, the write_image built-ins are also supported
+ * for 2D images created from a buffer.
+ *
+ * When the 2D image from buffer is created, the client must specify the width,
+ * height, image format (i.e. channel order and channel data type) and optionally the row pitch
+ *
+ * The pitch specified must be a multiple of CL_DEVICE_IMAGE_PITCH_ALIGNMENT pixels.
+ * The base address of the buffer must be aligned to CL_DEVICE_IMAGE_BASE_ADDRESS_ALIGNMENT pixels.
