* 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
|
||||
* structure itself, thus ensuring no dynamic memory allocation. The
|
||||
* internal buffer is large enough to hold a reasonable paragraph of text,
|

* such as the current paragraph.

* @defgroup avoptions AVOptions
|
||||
* @ingroup lavu_data
|
||||
* @{
|
||||
* AVOptions provide a generic system to declare options on arbitrary structs
|
||||
* ("objects"). An option can have a help text, a type and a range of possible
|
||||
* values. Options may then be enumerated, read and written to.
|
||||
*
|
||||
* @section avoptions_implement Implementing AVOptions
|
||||
* This section describes how to add AVOptions capabilities to a struct.
|
||||
*
|
||||
* All AVOptions-related information is stored in an AVClass. Therefore
|
||||
* the first member of the struct should be a pointer to an AVClass describing it.
|
||||
* The option field of the AVClass must be set to a NULL-terminated static array
|
||||
* of AVOptions. Each AVOption must have a non-empty name, a type, a default
|
||||
* value and for number-type AVOptions also a range of allowed values. It must
|
||||
* also declare an offset in bytes from the start of the struct, where the field
|
||||
* associated with this AVOption is located. Other fields in the AVOption struct
|
||||
* should also be set when applicable, but are not required.
|
||||
*
|
||||
* The following example illustrates an AVOptions-enabled struct:
|
||||
* @code
|
||||
* typedef struct test_struct {
|
||||
* AVClass *class;
|
||||
* int int_opt;
|
||||
* char *str_opt;
|
||||
* uint8_t *bin_opt;
|
||||
* int bin_len;
|
||||
* } test_struct;
|
||||
*
|
||||
* static const AVOption options[] = {
|
||||
* { "test_int", "This is a test option of int type.", offsetof(test_struct, int_opt),
|
||||
* AV_OPT_TYPE_INT, { .i64 = -1 }, INT_MIN, INT_MAX },
|
||||
* { "test_str", "This is a test option of string type.", offsetof(test_struct, str_opt),
|
||||
* AV_OPT_TYPE_STRING },
|
||||
* { "test_bin", "This is a test option of binary type.", offsetof(test_struct, bin_opt),
|
||||
* AV_OPT_TYPE_BINARY },
|
||||
* { NULL },
|
||||
* };
|
||||
*
|
||||
* static const AVClass test_class = {
|
||||
* .class_name = "test class",
|
||||
* .item_name = av_default_item_name,
|
||||
* .option = options,
|
||||
* .version = LIBAVUTIL_VERSION_INT,
|
||||
* };
|
||||
* @endcode
|
||||
*
|
||||
* Next, when allocating your struct, you must ensure that the AVClass pointer
|
||||
* is set to the correct value. Then, av_opt_set_defaults() can be called to
|
||||
* initialize defaults. After that the struct is ready to be used with the
|
||||
* AVOptions API.
|
||||
*
|
||||
* When cleaning up, you may use the av_opt_free() function to automatically
|
||||
* free all the allocated string and binary options.
|
||||
*
|
||||
* Continuing with the above example:
|
||||
*
|
||||
* @code
|
||||
* test_struct *alloc_test_struct(void)
|
||||
* {
|
||||
* test_struct *ret = av_malloc(sizeof(*ret));
|
||||
* ret->class = &test_class;
|
||||
* av_opt_set_defaults(ret);
|
||||
* return ret;
|
||||
* }
|
||||
* void free_test_struct(test_struct **foo)
|
||||
* {
|
||||
* av_opt_free(*foo);
|
||||
* av_freep(foo);
|
||||
* }
|
||||
* @endcode
|
||||
*
|
||||
* @subsection avoptions_implement_nesting Nesting
|
||||
* It may happen that an AVOptions-enabled struct contains another
|
||||
* AVOptions-enabled struct as a member (e.g. AVCodecContext in
|
||||
* libavcodec exports generic options, while its priv_data field exports
|
||||
* codec-specific options). In such a case, it is possible to set up the
|
||||
* parent struct to export a child's options. To do that, simply
|
||||
* implement AVClass.child_next() and AVClass.child_class_next() in the
|
||||
* parent struct's AVClass.
|
||||
* Assuming that the test_struct from above now also contains a
|
||||
* child_struct field:
|
||||
*
|
||||
* @code
|
||||
* typedef struct child_struct {
|
||||
* AVClass *class;
|
||||
* int flags_opt;
|
||||
* } child_struct;
|
||||
* static const AVOption child_opts[] = {
|
||||
* { "test_flags", "This is a test option of flags type.",
|
||||
* offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX },
|
||||
* { NULL },
|
||||
* };
|
||||
* static const AVClass child_class = {
|
||||
* .class_name = "child class",
|
||||
* .item_name = av_default_item_name,
|
||||
* .option = child_opts,
|
||||
* .version = LIBAVUTIL_VERSION_INT,
|
||||
* };
|
||||
*
|
||||
* void *child_next(void *obj, void *prev)
|
||||
* {
|
||||
* test_struct *t = obj;
|
||||
* if (!prev && t->child_struct)
|
||||
* return t->child_struct;
|
||||
* return NULL
|
||||
* }
|
||||
* const AVClass child_class_next(const AVClass *prev)
|
||||
* {
|
||||
* return prev ? NULL : &child_class;
|
||||
* }
|
||||
* @endcode
|
||||
* Putting child_next() and child_class_next() as defined above into
|
||||
* test_class will now make child_struct's options accessible through
|
||||
* test_struct (again, proper setup as described above needs to be done on
|
||||
* child_struct right after it is created).
|
||||
*
|
||||
* From the above example it might not be clear why both child_next()
|
||||
* and child_class_next() are needed. The distinction is that child_next()
|
||||
* iterates over actually existing objects, while child_class_next()
|
||||
* iterates over all possible child classes. E.g. if an AVCodecContext
|
||||
* was initialized to use a codec which has private options, then its
|
||||
* child_next() will return AVCodecContext.priv_data and finish
|
||||
* iterating. OTOH child_class_next() on AVCodecContext.av_class will
|
||||
* iterate over all available codecs with private options.
|
||||
*
|
||||
* @subsection avoptions_implement_named_constants Named constants
|
||||
* It is possible to create named constants for options. Simply set the unit
|
||||
* field of the option the constants should apply to to a string and
|
||||
* create the constants themselves as options of type AV_OPT_TYPE_CONST
|
||||
* with their unit field set to the same string.
|
||||
* Their default_val field should contain the value of the named
|
||||
* constant.
|
||||
* For example, to add some named constants for the test_flags option
|
||||
* above, put the following into the child_opts array:
|
||||
* @code
|
||||
* { "test_flags", "This is a test option of flags type.",
|
||||
* offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX, "test_unit" },
|
||||
* { "flag1", "This is a flag with value 16", 0, AV_OPT_TYPE_CONST, { .i64 = 16 }, 0, 0, "test_unit" },
|
||||
* @endcode
|
||||
*
|
||||
* @section avoptions_use Using AVOptions
|
||||
* This section deals with accessing options in an AVOptions-enabled struct.
|
||||
* Such structs in FFmpeg are e.g. AVCodecContext in libavcodec or
|
||||
* AVFormatContext in libavformat.
|
||||
*
|
||||
* @subsection avoptions_use_examine Examining AVOptions
|
||||
* The basic functions for examining options are av_opt_next(), which iterates
|
||||
* over all options defined for one object, and av_opt_find(), which searches
|
||||
* for an option with the given name.
|
||||
*
|
||||
* The situation is more complicated with nesting. An AVOptions-enabled struct
|
||||
* may have AVOptions-enabled children. Passing the AV_OPT_SEARCH_CHILDREN flag
|
||||
* to av_opt_find() will make the function search children recursively.
|
||||
*
|
||||
* For enumerating there are basically two cases. The first is when you want to
|
||||
* get all options that may potentially exist on the struct and its children
|
||||
* (e.g. when constructing documentation). In that case you should call
|
||||
* av_opt_child_class_next() recursively on the parent struct's AVClass. The
|
||||
* second case is when you have an already initialized struct with all its
|
||||
* children and you want to get all options that can be actually written or read
|
||||
* from it. In that case you should call av_opt_child_next() recursively (and
|
||||
* av_opt_next() on each result).
|
||||
*
|
||||
* @subsection avoptions_use_get_set Reading and writing AVOptions
|
||||
* When setting options, you often have a string read directly from the
|
||||
* user. In such a case, simply passing it to av_opt_set() is enough. For
|
||||
* non-string type options, av_opt_set() will parse the string according to the
|
||||
* option type.
|
||||
*
|
||||
* Similarly av_opt_get() will read any option type and convert it to a string
|
||||
* which will be returned. Do not forget that the string is allocated, so you
|
||||
* have to free it with av_free().
|
||||
*
|
||||
* In some cases it may be more convenient to put all options into an
|
||||
* AVDictionary and call av_opt_set_dict() on it. A specific case of this
|
||||
* are the format/codec open functions in lavf/lavc which take a dictionary
|
||||
* filled with option as a parameter. This allows to set some options
|
||||
* that cannot be set otherwise, since e.g. the input file format is not known
|
||||
* before the file is actually opened.
