| #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. | |

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
Describe the class of an AVClass context structure.
That is an arbitrary struct of which the first field is a pointer to an AVClass struct (e.g. AVCodecContext, AVFormatContext etc.).
| void av_log | ( | void * | avcl, | |
| int | level, | |||
| const char * | fmt, | |||
| ... | ||||
| ) |
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 av_vlog 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, lower values signifying higher importance. | |
| fmt | The format string (printf-compatible) that specifies how subsequent arguments are converted to output. |
