当我尝试通过 ffmpeg 制作用于奶牛跟踪的 2D 动画图（匹配 2 个摄像机视图）时，出现以下错误。
raise subprocess.CalledProcessError(subprocess.CalledProcessError: Command '['ffmpeg', '-f', 'rawvideo', '-vcodec', 'rawvideo', '-s', '4000x4000', '-pix_fmt', 'rgba', '-r', '5', '-loglevel', 'error', '-i', 'pipe:', '-vcodec', 'h264', '-pix_fmt', 'yuv420p', '-metadata', 'artist=Me', '-y', '../out_detect/run7/TRACKS_ANIMATION_fused.mp4']' returned non-zero exit status 1.

我还通过conda安装了ffmpy。
如果有人能帮助我，我将非常感激。
我通过重新安装ffmpeg解决了这个问题。 首先，我考虑到bin目录下的ffmpeg和conda ffmpeg有冲突，所以我先通过
删除了bin目录下的ffmpeg$ sudo apt-get remove ffmpeg libav-tools
$ sudo apt-get autoremove ffmpeg
此时CUDA和nvidia驱动也被抹掉，必须重新安装。
然后重新启动计算机。
之后，我执行创建2D动画地图代码，但出现了同样的错误。
所以我最后删除了conda ffmpeg和pip ffmpy并重新安装了，（此时torchvision也被删除了，我不得不重新安装）
$ conda uninstall ffmpeg
$ pip uninstall ffmpy
$ conda install -c pytorch torchvision
问题就解决了！ ffmpeg 工作正常。 我也不知道到底是什么问题。
您安装的 ffmepg 程序似乎不兼容。重新安装你的 ffmpeg:
$ conda uninstall ffmpeg
$ conda install conda-forge::ffmpeg
应该可以。如果没有，尽管不太可能，请尝试使用 homebrew 重新安装 ffmpeg。
$brew uninstall ffmpeg
$brew install ffmpeg
