我有一些 MP4 视频文件在其标题信息中缺少像素格式。我已经尝试将其设置为最大值 2147483647，但这并没有帮助probesize。analyzeduration
所以我知道这些视频可能已损坏，但如果这是唯一缺少的信息，我想我可以通过重建它们的标题信息或通过强制像素格式以某种方式解码它们来恢复它们。有谁知道这是否可能？该文件的更多背景信息：

我不能以这种方式在 ffmpeg 上强制使用 pixel_format：
$ ffmpeg -pixel_format yuv420p -i DJI_0090.MOV test.mp4

有没有其他方法可以用 ffmpeg 完成这个？是否可以编辑其标题信息以包含像素格式信息？
