ffmpeg - 复制视频编解码器后，“hevc”编解码器更改为“rawvideo”

编程问答 2022-05-22

问题描述

我正在尝试将一些带有 mkv 编解码器的 hevc 视频转换为 avi 格式。为此，我运行以下命令：

ffmpeg -i input.mkv -vcodec copy -acodec copy out.avi

对于某些视频，此命令可以正常工作。但在某些情况下，视频确实会转换，但我无法在任何视频播放器中播放这些文件。我尝试了几种视频播放器，包括 VLC、SMPlayer、Deepin Movie 等。

查看转换视频的视频编解码器后，我可以看到视频编解码器从 hevc 转换为 rawvideo。她的是原视频文件和转换后的视频文件的流信息：

如何解决这个问题？

解决方法

不要使用AVI

AVI 不适用于 HEVC。
使用现代输出容器格式，例如 MP4、MOV 或 MKV。

如果您需要 AVI

一种解决方法是添加 -vtag hvc1 输出选项。

ffmpeg -i input.mkv -c copy -vtag hvc1 out.avi

或者告诉ffmpeg AVI 有 HEVC 视频：

ffmpeg -c:v hevc -i input.avi
ffmpeghevcvideo
