/**
* 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).
*

* AV_PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
* color is put together as:
* (A << 24) | (R << 16) | (G << 8) | B
* This is stored as BGRA on little-endian CPU architectures and ARGB on
* big-endian CPUs.
*
* @par
* When the pixel format is palettized RGB32 (AV_PIX_FMT_PAL8), the palettized
* image data is stored in AVFrame.data[0]. The palette is transported in
* AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
* formatted the same as in AV_PIX_FMT_RGB32 described above (i.e., it is
* also endian-specific). Note also that the individual RGB32 palette
* components stored in AVFrame.data[1] should be in the range 0..255.
* This is important as many custom PAL8 video codecs that were designed
* to run on the IBM VGA graphics adapter use 6-bit palette components.
*
* @par
* For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
* for pal8. This palette is filled in automatically by the function
* allocating the picture.
