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_dlog(pctx,...)
	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.
