#define AV_LOG_QUIET   -8

Print no output.

Definition at line 163 of file log.h.

#define AV_LOG_WARNING   24

Something somehow does not look correct.

This may or may not lead to problems. An example would be the use of '-vstrict -2'.

Examples
transcoding.c.

Definition at line 202 of file log.h.

◆ AV_LOG_TRACE

#define AV_LOG_TRACE   56

Extremely verbose debugging, useful for libav* development.

Examples
http_multiclient.c.

Definition at line 207 of file log.h.

◆ AV_LOG_MAX_OFFSET

#define AV_LOG_MAX_OFFSET   (AV_LOG_TRACE - AV_LOG_QUIET)

Definition at line 209 of file log.h.
