使用or +时在哪里mpv保存或记录状态？--save-position-on-quitShiftq
这用于保存退出状态，以便视频在退出时从中断的地方开始播放mpv。
我总是使用mpv媒体播放器来播放媒体文件（视频/音频）。
但我想要“每当我通过 MPV 打开视频/音频时，它应该默认静音”。
我试图添加cycle mute到input.conf文件的最后一行。
但它没有用。
有时我mpv用来播放.mpd文件。这些是本地文件或流文件。当播放开始时，mpv检测最高的视频分辨率和音频质量并开始使用它们。
例如，这是连接到流式传输的.mpd文件时出现在终端窗口中的内容：
Video --vid=1 'bitrate 499950' (h264 640x360 600.000fps)
Video --vid=2 'bitrate 999965' (h264 768x432 600.000fps)
Video --vid=3 'bitrate 1999931' (h264 1280x720 600.000fps)
Video --vid=4 'bitrate 2999896' (h264 1920x1080 600.000fps)
(+) Video --vid=5 'bitrate 3999862' (h264 1920x1080 600.000fps)
Audio --aid=1 'bitrate 96000' (aac 2ch 48000Hz)

Audio --aid=4 'bitrate 256000' (aac 2ch 48000Hz)

加号显示自动选择的视频和音频。
是否有任何方法或命令可以告诉mpv使用特定的视频分辨率和音频质量而不是自动检测到的？
谢谢你。

升级
就在最近，我运行了 sudo apt upgrade 以便从终端升级我的软件。在此之前，一切都很好。我能够播放带有视频和音频的视频。并且 mkv 文件用于顺利运行，允许在文件中选择任何语言/字幕或任何其他选项。
收到的错误
我mpv用来播放我的 mkv 和其他格式的文件，如 ogv、mpg、mpeg2、mp4 等。
升级系统中的所有软件后，我开始使用这种屏幕而不是视频本身。
其他视频播放器也有类似的行为，几秒钟后变得无响应并引发高处理器负载，但似乎他们正在寻找编解码器、插件或其他东西以做好工作，但他们没有达到。
播放器
似乎是我可以播放此视频的唯一方法，但存在一些错误，例如错误的视频持续时间。

我目前正在使用带有统一 DE 的 Ubuntu 19.10，并且我总是用来mpv在 Ubuntu 中播放视频。由于mpvGUI 选项很少，因此没有用于旋转视频的 GUI 选项，但我们可以在命令行的帮助下旋转它。例如，我们可以使用以下命令将视频旋转 90 度：
mpv --video-rotate=90 /home/guest/new_vdo.mp4
但是，通过这种方式（使用终端），我每次想要旋转视频时都必须输入命令。
我们如何创建键盘快捷键来旋转当前正在播放的视频mpv？
我使用了多个依赖于 ffmpeg 的工具，其中一些工具已经从软件包存储库中提供的那个下载了不同版本的 ffmpeg（例如，mpv 和通过 imageio 的moviepy）。这些程序的单独 ffmpeg 二进制文件没有相互干扰，但我遇到了与不同版本之间的一些不一致有关的困难。
我的问题是：如何找到我系统上存在的不同版本的 ffmpeg（除了 ubuntu 包），以便我可以将所有内容指向最新版本的二进制文件（在我的情况下，ffmpeg 与 mpv 一起运行） ?
谢谢！
