Macros | |
| #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. | |
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) |

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.
Also to receive the last, "last repeated" line if any, the user app must call av_log(NULL, AV_LOG_QUIET, "%s", ""); at the end

Send the specified message to the log if the level is less than or equal to the current av_log_level.
By default, all logging messages are sent to stderr. This behavior can be altered by setting a different logging callback function.
| avcl | A pointer to an arbitrary struct of which the first field is a pointer to an AVClass struct. |
| level | The importance level of the message expressed using a Logging Constant. |
| fmt | The format string (printf-compatible) that specifies how subsequent arguments are converted to output. |
