YouTube API 截断视频 [PHP]

我正在使用YouTube API逐块上传视频（请参阅下面的代码）。但是，对于较大的文件（+ 1GB），上传有时会失败，但并非总是如此。上传显示为已完成，但只能播放几分钟，其余部分将被截断。我做了一些研究，但没有明显的成功。我现在的问题：

• 有没有可能直接联系YouTube（查看真正发生的事情的日志）？
• 这是编码问题吗？
• 是否可以通过API捕获/检测到错误（目前，不会引发异常）
• 如果您一次上传不同的视频（即并行），是否会发生这种情况？
• 是否有其他人遇到过此问题？

任何朝着正确方向的帮助/领导都非常感谢。我甚至会喊出500分的赏金，因为这让我发疯（刚刚做到了......）

附录：脚本在命令行上运行，通过Gearman服务器，设置。代码/函数只是一个提取（对于较小的文件，有时甚至高达10GB）运行良好）。set_time_limit(0);

编辑：根据上面的 aergistal 和 GeorgeQ 的评论，我已将 while 循环更改为直接读取块（不再）并将状态保存到数据库中。feof()
