我使用VLC播放器录制了一个短视频（1分钟，55MB）的屏幕，播放时没有任何问题。现在我录制了更长的视频（大约3小时，12GB），没有录制问题（我使用的方式和以前一样），但视频无法播放。这就是VLC所说的
VLC can't recognize the input's format:
The format of 'file:///D:/Video/ET01.mp4' cannot be detected. Have a look at the log for details.
并且日志说：

我尝试用Avidemux打开它，但它只是说文件无法打开。我使用了MP4 / MOV封装，MPEG-4编解码器，800 kb / s比特率，24帧速率，完全没有音频和字幕。 我想知道是否有办法修复此文件。
编辑：我注意到我可能会以错误的方式停止录制。我按下“停止”按钮。时间停止计数，但标题仍在说“流媒体”，我完全退出了VLC播放器。所以这应该是问题。
