在ubuntu中，使用工业相机读取视频流，无音频流，并通过rtmp推流，打算使用http-flv拉流，终端提示WriteN, RTMP send error 32 (129 bytes) WriteN, RTMP send error 32 (39 bytes) WriteN, RTMP send error 9 (42 bytes)，我发现如果只编译nginx-rtmp模块的话，推流没啥问题，但是我一旦编译nginx-http-flv模块，推流就会提示以上信息，使用命令行推流的话也没问题，但是我需要实时读取并推流，这是nginx的问题还是我代码的问题？代码中这个最后一步ret_code = av_interleaved_write_frame(format_context,&pack);返回值一直是-1

日志已经告诉你了，发送的 avc header 不完整，需要至少 18 个字节，nginx-rtmp-module 没做检查。
