Raspberry pi Raspberry Pi 4是否保存损坏的h264文件？

我已经能够毫无问题地录制.h264文件，无论是使用raspivid还是通过Python，但是无论我做什么尝试，我都无法将它们转换为.mp4、.mkv或.avi文件

我尝试过使用MP4box（在几个地方建议）和mkvmerge进行转换，但没有效果

当我使用MP4box（MP4box-add）时，我得到：

然后我尝试用VLC播放这个文件，它没有给出错误，但显示的是乱码数据

为了清楚起见，相机工作正常（使用Python代码显示完美的视频，raspistill输出完美的jpg文件）。我也试了一台不同的相机

尝试使用mkvmerge：

pi@raspberrypi:~/cam $ raspivid -o test.h264 -fps 30 -t 15000 -w 1920 -h 1080
pi@raspberrypi:~/cam $ mkvmerge --default-duration 0:30p -o video.mkv test.h264
mkvmerge v31.0.0 ('Dolores In A Shoestand') 32-bit
'test.h264': Using the demultiplexer for the format 'AVC/h.264'.
'test.h264' track 0: Using the output module for the format 'AVC/h.264 (unframed)'.
The file 'video.mkv' has been opened for writing.
Error: 'test.h264' track 0: mkvmerge encountered broken or unparsable data in this AVC/h.264 video track. Either your file is damaged (which mkvmerge cannot cope with yet) or this is a bug in mkvmerge itself. The error message was:
Success
pi@raspberrypi:~/cam $

这是在覆盆子皮4上

可以在此处找到示例文件：

创建时使用：raspivid-t 30000-w 640-h 480-fps 25-b 1200000-p 0,0640480-o pivideo.h264

我将自己对此做出回应。执行“apt get升级”后，问题消失了

如果有人想找出根本原因，apt get就是这么做的：

我一直使用

ffmpeg

对内容进行重新编码，尽管不是这种特殊情况（这就是为什么它是注释而不是答案）。奇怪的是，它报告了一个错误，但没有给出文本。您确定输入是h264吗？鉴于您尝试使用的

mp4box

与相同，它可能是录制端的内容。您可以共享您的h.264文件吗？可以在此处找到示例文件：
