I converted fmp4 files into TS files by imitating the code of converting MP4 files into TS files. 我通过模仿将MP4文件转换为TS文件的代码将fmp4文件转换为TS文件。 I encountered a problem: There is CTTS box in MP4 file, but there is no CTTS box in fmp4 file. 我遇到了一个问题：MP4文件中有CTTS框，但fmp4文件中没有CTTS框。 The information inside CTTS (PTS = STTS + CTTS) is needed when calculating video PTS. 计算视频PTS时需要CTTS内部的信息（PTS = STTS + CTTS）。 What should I do? 我该怎么办？ My h264 frame has no B frame. 我的h264框架没有B框架。 Do I need a CTTS box? 我需要一个CTTS盒子吗？
