ffmpeg 中使用 H265 的 Lavf58.29.100 和 Lavc58.134.100 eac3 编码有什么区别？
我使用 ffmpeg 和 handbrake 软件创建了一个 mkv 文件，但两者都使用不同的编码，handbrake 使用 Lavf58.29.100 而 ffmpeg 使用 Lavc58.134.100 eac3 我怎样才能告诉 ffmpeg 使用与 handbrake 相同的 Lavf58.29.100？
ffmpeg -i 0.mp4 -c:v libx265 -preset fast -crf 28 -tag:v hvc1 -c:a eac3 -b:a 224k out.mkv

我也尝试了 ffmpeg-python 包，但是在使用 H265 时出现错误：
(
ffmpeg
.input('0.mp4')
.filter('fps', fps=25, round='up')
.output('out.mkv', format='h265')
.run()
)
我收到的错误：
Requested output format 'h265' is not a suitable output format
out.mkv: Invalid argument
