Something went wrong and cannot losslessly be recovered.
However, not all future data is affected.
Definition at line 102 of file log.h.
Something went wrong and recovery is not possible.
For example, no header was found for a format which depends on headers or an illegal combination of parameters is used.

#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, "%s", ""); at the end

Something somehow does not look correct.
This may or may not lead to problems. An example would be the use of '-vstrict -2'.

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.
- Parameters:
-
| 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. |
- See also:
- av_vlog
