h.264 - H.264到传输流转码器问题

我在这里的第一篇文章[请原谅最终的格式/表述/等问题]。我正在将原始H.264写入mpeg 2传输流转码器（仅更改容器，本身不涉及视频转码）。我认为我理解mpeg 2传输流规范（H.222.0）但我无法让QuickTime回放生成的.ts文件（VLC和FFMPEG播放回来）。我在做什么：

使用程序映射pid 53
使用pid 53为PCR PID 70创建PMT
将原始NALU分成带有PID 70的PES包 - 在PES小于184字节长的情况下添加带填充字节的适配字段

我有两个（几乎相同的）文件 - 其中一个是由VLC转储的两个帧.ts文件，另一个是由VLC转储的两个帧.ts文件转码为原始H.264，而后者又转码再次使用我的工具.ts差异很小，但对于我的生活，QuickTime只播放原始的VLC .ts，而不是我的转码。我使用来自http://tstools.berlios.de的tsreport来报告各种.ts文件结构，它们看起来几乎相同。以下是tsreport抛弃的日志。有任何想法吗？

我上面的VLC .ts文件，从中提取原始比特流 - 然后我用我的工具将它再次转换为.ts;我的.ts的tsreport日志如下：

事实证明，在每个NALU之前我有NALU类型9 - 也就是说，我的流是9 7 9 8 9 6 9 5 ...而不是9 7 8 6 5 9 1 9 1 ...
