我有一台旧的迷你高清摄像机，它使用 MJPEG 编解码器输出 AVI 文件。我有一些新文件无法在 Windows 视频实用程序中打开，我想修复它们。ffprobe 抱怨：
[avi @ 000001d0b6125980] Could not find codec parameters for stream 0 (Video: mjpeg (MJPG / 0x47504A4D), none(bt470bg/unknown/unknown), 1920x1080): unspecified pixel format
Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options
但是，我确实有一些旧文件可以正常播放。是否可以使用从好的视频文件中获取的参数让 ffmpeg 修复坏的视频文件？
以下是 mediainfo 输出：
