Функции

av_get_media_type_string()

const char* av_get_media_type_string

(

enum AVMediaType

media_type

)

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavutil/avutil.h>

Return a string describing the media_type enum, NULL if media_type is unknown.

av_x_if_null()

static void* av_x_if_null ( const void *  p, const void *  x  )

inlinestatic

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavutil/avutil.h>

Return x default pointer in case p is NULL.

См. определение в файле avutil.h строка 308

{
    return (void *)(intptr_t)(p ? p : x);
}

av_int_list_length_for_size()

unsigned av_int_list_length_for_size	(	unsigned	elsize,
		const void *	list,
		uint64_t	term
	)

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavutil/avutil.h>

Compute the length of an integer list.

Аргументы

elsize	size in bytes of each list element (only 1, 2, 4 or 8)
term	list terminator (usually 0 or -1)
list	pointer to the list

Возвращает

length of the list, in elements, not counting the terminator

av_fopen_utf8()

FILE* av_fopen_utf8	(	const char *	path,
		const char *	mode

(

void

)

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavutil/avutil.h>

Аргументы

buf	a buffer with size in bytes of at least AV_FOURCC_MAX_STRING_SIZE
fourcc	the fourcc to represent

Возвращает

the buffer in input
