当我尝试通过ffmpeg制作奶牛跟踪的2D动画地图(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，我将不胜感激。我通过重新安装ffmpeg解决了这个问题。首先，我考虑了bin目录的ffmpeg和conda ffmpeg之间的冲突，因此我首先通过
删除了bin目录的ffmpeg。$ sudo apt-get remove ffmpeg libav-tools
$ sudo apt-get autoremove ffmpeg
此时，CUDA和nvidia驱动也被擦除，必须重新安装。
并重新启动计算机。
之后，我执行创建2d动画地图代码，但同样的错误发生。
所以我最后删除了conda ffmpeg和pip ffmpy并重新安装，(此时，torchvision也被删除，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。
