| Convenience macro, the return value should be used only directly in function arguments but never stand-alone.

## Functions

int | av_strerror (int errnum, char *errbuf, size_t errbuf_size)
| Put a description of the AVERROR code errnum in errbuf.
static char * | av_make_error_string (char *errbuf, size_t errbuf_size, int errnum)
| Fill the provided buffer with a string containing an error string corresponding to the AVERROR code errnum.
