最佳答案
问题
您正在使用 ancient, dead, buggy, broken, useless, counterfeit " ffmpeg
" from Libav ,不是现代的,真实的ffmpeg
来自 FFmpeg。
解决方案
幸运的是,您可以轻松 download真实事物的最新版本并改用它:
wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz
tar xvf https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz
/usr/local/bin
sudo cp ffmpeg-git-*-64bit-static/ff* /usr/local/bin
ffmpeg
命令,它应该使用您下载的版本。
/usr/local/bin
中删除 FFmpeg 二进制文件即可。 .sudo rm -f /usr/local/bin/{ffmpeg,ffmpeg-10bit,ffprobe,ffserver}
ffmpeg
命令仍然执行旧的、糟糕的版本,然后你当前的 shell session 正在记住旧的位置。运行hash -r
或只是注销/登录。你只需要这样做一次。 ffmpeg
而不是依赖第三方提供二进制文件。 ffmpeg
然后你可以把它放在~/bin
而不是 /usr/local/bin
.然后运行 source ~/.profile
刷新PATH
或者只是注销/登录(您只需执行一次)。如果您没有 root 或 super 用户权限,这也适用。 关于video - ffmpeg -bsf :v h264_mp4 toannexb not working in debien,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/43236718/
