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_C(x)   (x << 8)
 Sets additional colors for extended debugging sessions.
#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.
