Anybody knows where is a list of the AVERROR meanings? Something like

-2: reason B
以此类推?
推荐答案
在这里(摘录自 libavutil/error.c ):
{ ERROR_TAG(BSF_NOT_FOUND), "Bitstream filter not found" },
{ ERROR_TAG(BUG), "Internal bug, should not have happened" },
{ ERROR_TAG(BUG2), "Internal bug, should not have happened" },
{ ERROR_TAG(BUFFER_TOO_SMALL), "Buffer too small" },
{ ERROR_TAG(DECODER_NOT_FOUND), "Decoder not found" },
{ ERROR_TAG(DEMUXER_NOT_FOUND), "Demuxer not found" },
{ ERROR_TAG(ENCODER_NOT_FOUND), "Encoder not found" },
{ ERROR_TAG(EOF), "End of file" },
{ ERROR_TAG(EXIT), "Immediate exit requested" },
{ ERROR_TAG(EXTERNAL), "Generic error in an external library" },
{ ERROR_TAG(FILTER_NOT_FOUND), "Filter not found" },
{ ERROR_TAG(INVALIDDATA), "Invalid data found when processing input" },
{ ERROR_TAG(MUXER_NOT_FOUND), "Muxer not found" },
{ ERROR_TAG(OPTION_NOT_FOUND), "Option not found" },
{ ERROR_TAG(PATCHWELCOME), "Not yet implemented in FFmpeg, patches welcome" },
{ ERROR_TAG(PROTOCOL_NOT_FOUND), "Protocol not found" },
{ ERROR_TAG(STREAM_NOT_FOUND), "Stream not found" },
{ ERROR_TAG(UNKNOWN), "Unknown error occurred" },
但这是与版本有关的方式,最好使用av_strerror()
让库为您提供错误代码的字符串表示形式.
But this is version-dependent way and it is better to use av_strerror()
to let the library give you a string representation of the error code.
