我正在尝试将一些使用 hevc 编解码器的 mkv 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，视频确实已转换，但我无法在任何视频播放器中播放这些文件。我尝试过多种视频播放器，包括VLC、SMPlayer、深度影院等。
查看转换后的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。她的是原始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？
最佳答案
不要使用 AVI
AVI 不适合与 HEVC 一起使用。
使用现代输出容器格式，例如 MP4、MOV 或 MKV。
如果您需要 AVI
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 具有 HEVC 视频:
ffmpeg -c:v hevc -i input.avi
关于video - ffmpeg - 复制视频编解码器后， 'hevc' 编解码器更改为 'rawvideo'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/66563579/
