#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. |
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 *avcl, int level, const char *fmt, va_list vl) |
Default logging callback. | |
const char * | av_default_item_name (void *ctx) |
Return the context name. | |
void | av_log_set_flags (int arg) |

#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.
Also to receive the last, "last repeated" line if any, the user app must call av_log(NULL, AV_LOG_QUIET, ""); 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. |
