ffmpeg：转换为与三星蓝光兼容的 mkv
ffmpeg : Conversion to mkv with compatibility with Samsung BluRay
我有几个视频（全高清分辨率），我想将其转换为 mkv 格式并在我的三星蓝光播放器（型号 BD-J5900）上播放。
根据用户手册（http://media.datatail.com/docs/manual/252846_en.pdf，第 6 页），如果编解码器是：
，它支持 mkv 播放
- 视频：H.264 BP/MP/HP
- 音频：MP3
因此，基于https://ffmpeg.org/ffmpeg.html将其转换为正确格式的命令是：
ffmpeg -i input.avi -f matroska -vcodec libx264 -acodec mp3 output.mkv
可以转换，但文件无法在播放器上播放。它说 "Video format is not supported".
在此处检查信息后：https://trac.ffmpeg.org/wiki/Encode/H.264 - 我认为它可能需要一些兼容性并将命令更改为：
ffmpeg -i input.avi -f matroska -vcodec libx264 -profile:v baseline -level 3.0 -acodec mp3 output.mkv
但这也无济于事 - 播放器显示了同样的错误。
如何解决？
谢谢！
更新：
还测试了以下选项
ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -x264-params bluray_compat=1 -acodec mp3 output.mkv
ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -profile:v high -level 4.2 -x264-params bluray_compat=1 -acodec mp3 output.mkv
ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -profile:v baseline -level 3.0 -x264-params bluray_compat=1 -acodec mp3 output.mkv
ffmpeg -i input.file -vcodec libx264 -vf format=yuv420p -preset veryslow -acodec mp3 output.mkv
也不支持。

已在 Windows 10 [x64] 上使用 ffmpeg 4.0.2 进行测试
可能有空间使用 CRF 来减小最终文件的大小。
我有几个视频（全高清分辨率），我想将其转换为 mkv 格式并在我的三星蓝光播放器（型号 BD-J5900）上播放。 根据用户手册（http://media.datatail.com/docs/manual/252846_en.pdf，第 6 页），如果编解码器是：
，它支持 mkv 播放- 视频：H.264 BP/MP/HP
- 音频：MP3
因此，基于https://ffmpeg.org/ffmpeg.html将其转换为正确格式的命令是：
ffmpeg -i input.avi -f matroska -vcodec libx264 -acodec mp3 output.mkv
可以转换，但文件无法在播放器上播放。它说 "Video format is not supported".
在此处检查信息后：https://trac.ffmpeg.org/wiki/Encode/H.264 - 我认为它可能需要一些兼容性并将命令更改为：
ffmpeg -i input.avi -f matroska -vcodec libx264 -profile:v baseline -level 3.0 -acodec mp3 output.mkv
但这也无济于事 - 播放器显示了同样的错误。
如何解决？ 谢谢！
