FFmpeg 视频元数据更改

Question

我正在尝试更改视频流元数据。请参阅下面的(更改此元数据)。我可以更改电影的标题，但不能更改其他任何名称。改变这一点的 ffmpeg 行是什么。

下面的这一行仅更改“电影标题”

ffmpeg -i Input.mkv -metadata title="新标题"-c:v 复制 -c:a 复制 -c:s 复制 Output.mkv

Input #0, matroska,webm, from 'Input.mkv':

Answer 1

好的，我发现这个可行:

ffmpeg -i Input.mkv -metadata:s:v:0 title="H264 Video" -c:v copy -c:a copy -c:s copy Output.mkv

我认为 :s:v:0一些评论代表:
:v = 视频流
:0 = 使用第一个视频流
