我有一个.ts格式的自记录文件，希望将其转换为三种不同的格式（.mp4，.ogg和.webm）。
为此，我将我的全新debian9与以下命令配合使用：
/usr/bin/ffmpeg -y -i source.ts -strict experimental -r 25 -b 18550k -bt 22792k -acodec aac -ac 2 -ar 48000 -ab 320k output.mp4
/usr/bin/ffmpeg -y -i source.ts -r 25 -b 18550k -bt 22792k -vcodec libtheora -acodec libvorbis -ac 2 -ar 48000 -ab 320k output.ogg
/usr/bin/ffmpeg -y -i source.ts -r 25 -b 18550k -bt 22792k -ac 2 -ar 48000 -ab 320k output.webm

为什么我要这么做？我只是使用privat内部网（网络应用程序）玩转游戏，以在不同客户端（智能手机，平板电脑，台式机）上流式传输自己录制的文件。这也是使用不同格式（.mp4，.ogg，.webm）的原因
我当前的问题是：将其转换为.webm的命令返回以下错误：
/usr/bin/ffmpeg -y -i test.ts -r 25 -b 18550k -bt 22792k -ac 2 -ar 48000 -ab 320k output.webm

我不明白问题所在，因为可以转换为.ogg或.mp4。因此，我不会成为源编解码器的问题。有谁知道我的问题可能是什么
