我在mkv文件上使用ffprobe以获取有关章节结构的一些信息，以便使用ffmpeg拆分mkv。
ffprobe miku.mkv -print_format xml
但是ffprobe遇到了scodec错误（不影响章节信息），我无法通过设置打印格式来获取信息。我知道有一些方法可以绕过错误，但是我仍然希望得到xml / json文件，以便它可以轻松解析。
我想知道是否有办法输入错误并输出xml / json文件或是否有错误的解决方案。 （但我更喜欢前者的解决方案，因为我不知道我可能遇到的任何错误，只要章节信息可用，我希望看到它有效）
错误是这样的。

这是显示出良好解决方案的a link：
对于JSON：ffprobe -v quiet -print_format json -show_format -show_streams "lolwut.mp4" > "lolwut.mp4.json"
对于XML：ffprobe -v quiet -print_format xml -show_format -show_streams "lolwut.mp4" > "lolwut.mp4.xml"
你会得到
