#define	AVERROR_STREAM_NOT_FOUND   FFERRTAG(0xF8,'S','T','R')
	Stream not found.
#define	AVERROR_BUG2   FFERRTAG( 'B','U','G',' ')
	This is semantically identical to AVERROR_BUG it has been introduced in Libav after our AVERROR_BUG and with a modified value.
#define	AVERROR_UNKNOWN   FFERRTAG( 'U','N','K','N')
	Unknown error, typically from an external library.
#define	AVERROR_EXPERIMENTAL   (-0x2bb2afa8)
	Requested feature is flagged experimental. Set strict_std_compliance if you really want to use it.
#define	AVERROR_INPUT_CHANGED   (-0x636e6701)
	Input changed between calls. Reconfiguration is required. (can be OR-ed with AVERROR_OUTPUT_CHANGED)
#define	AVERROR_OUTPUT_CHANGED   (-0x636e6702)
	Output changed between calls. Reconfiguration is required. (can be OR-ed with AVERROR_INPUT_CHANGED)
#define	AV_ERROR_MAX_STRING_SIZE   64
#define	av_err2str(errnum)   av_make_error_string((char[AV_ERROR_MAX_STRING_SIZE]){0}, AV_ERROR_MAX_STRING_SIZE, errnum)
	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.
