Data Structures

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

Macros

#define AV_IS_INPUT_DEVICE(category)
 
#define AV_IS_OUTPUT_DEVICE(category)
 
#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_LOG_TRACE   56
 Extremely verbose debugging, useful for libav* development.
 
#define AV_LOG_C(x)   ((x) << 8)
 Sets additional colors for extended debugging sessions.
 
#define av_dlog(pctx,...)   do { if (0) av_log(pctx, AV_LOG_DEBUG, __VA_ARGS__); } while (0)
 av_dlog macros
 
#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.
 
#define AV_LOG_PRINT_LEVEL   2
 Include the log severity in messages originating from codecs.
