C libavformat:av_交错_写入_帧-无法处理非交错数据

我正在尝试从ffmpeg示例代码运行remuxing.c示例。我正在使用它将包含h264、aac的TS文件还原为FLV格式

正在馈送的TS数据包未正确交错。因此，我正在使用

[av\u interleave\u write\u frame][1]

函数进行muxing。即使这样，我还是得到了以下错误

[flv @ 0x7feab581d400] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 2464 >= 2379

我是否使用了错误的API？任何帮助都将不胜感激

以下是日志片段：
