我正在尝试通过ffmpeg将视频网址从youtube更改为mp3，以便我可以在Ubuntu 14.04中传输响应
ffmpeg -i https://r7---sn-ab5l6ne7.googlevideo.com/videoplayback?mime=video%2Fmp4&requiressl=yes&signature=99EFD8B801C44EA1221B5D653B2EB30C4CE962C6.6CD123737E54A11B0E5B16BC7AA2572688B091D9&source=youtube&mn=sn-ab5l6ne7&upn=2c_sPjXh1FE&itag=22&pl=16&mt=1450291179&ms=au&expire=1450312883&mm=31&id=o-ABMSf6BaCXTeSmFM41vs85JJ2rmcdeD6CVriiGKVMDlG&sver=3&ratebypass=yes&ip=68.9.161.152&sparams=dur%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cpl%2Cratebypass%2Crequiressl%2Csource%2Cupn%2Cexpire&key=yt6&lmt=1429526600478294&dur=6.385&fexp=9416126%2C9420452%2C9422596%2C9423459%2C9423662&mv=m&ipbits=0&initcwndbps=2147500 -acodec liblamemp3 -f mp3 shave.mp3
但是当我运行此命令时，我最终会遇到此问题

现在我不确定为什么它会一直吐出来。我试图用＆＃39; - ＆＃39;做一个流输出。变量也没有用。
我已经安装了ffmpeg和所有依赖项。我使用this bash script来编译ffmpeg。我已经尝试了几天才能使这项工作仍然无法弄明白。
