Data Structures
struct	AVClass
	Describe the class of an AVClass context structure. More...

Macros
#define	AV_LOG_QUIET -8
	Print no output.

#define	AV_LOG_PANIC 0
	Something went really wrong and we will crash now.

#define	AV_LOG_FATAL 8
	Something went wrong and recovery is not possible.

#define	AV_LOG_ERROR 16
	Something went wrong and cannot losslessly be recovered.

#define	AV_LOG_WARNING 24
	Something somehow does not look correct.

#define	AV_LOG_INFO 32
	Standard information.

#define	AV_LOG_VERBOSE 40
	Detailed information.

#define	AV_LOG_DEBUG 48
	Stuff which is only useful for libav* developers.

#define	AV_LOG_MAX_OFFSET (AV_LOG_DEBUG - AV_LOG_QUIET)

#define	av_dlog(pctx,...) do { if (0) av_log(pctx, AV_LOG_DEBUG, __VA_ARGS__); } while (0)
	av_dlog macros Useful to print debug messages that shouldn't get compiled in normally.

#define	AV_LOG_SKIP_REPEATED 1
	Skip repeated messages, this requires the user app to use av_log() instead of (f)printf as the 2 would otherwise interfere and lead to "Last message repeated x times" messages below (f)printf messages with some bad luck.

Enumerations
enum	AVClassCategory { AV_CLASS_CATEGORY_NA = 0, AV_CLASS_CATEGORY_INPUT, AV_CLASS_CATEGORY_OUTPUT, AV_CLASS_CATEGORY_MUXER, AV_CLASS_CATEGORY_DEMUXER, AV_CLASS_CATEGORY_ENCODER, AV_CLASS_CATEGORY_DECODER, AV_CLASS_CATEGORY_FILTER, AV_CLASS_CATEGORY_BITSTREAM_FILTER, AV_CLASS_CATEGORY_SWSCALER, AV_CLASS_CATEGORY_SWRESAMPLER, AV_CLASS_CATEGORY_NB }

Functions
void	av_log (void avcl, int level, const char fmt,...) av_printf_format(3
	Send the specified message to the log if the level is less than or equal to the current av_log_level.

void void	av_vlog (void avcl, int level, const char fmt, va_list vl)
	Send the specified message to the log if the level is less than or equal to the current av_log_level.

int	av_log_get_level (void)
	Get the current log level.

void	av_log_set_level (int level)
	Set the log level.

void	av_log_set_callback (void(callback)(void , int, const char *, va_list))
	Set the logging callback.

void	av_log_default_callback (void ptr, int level, const char fmt, va_list vl)
	Default logging callback.

const char *	av_default_item_name (void *ctx)
	Return the context name.

AVClassCategory	av_default_get_category (void *ptr)

void	av_log_format_line (void ptr, int level, const char fmt, va_list vl, char line, int line_size, int print_prefix)
	Format a line of log the same way as the default callback.

void	av_log_set_flags (int arg)
