ffmpeg将文件转换为webm返回错误

时间:2019-04-14 16:57:08

标签: ffmpeg debian codec webm

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:

Stream mapping:
  Stream #0:3 -> #0:0 (h264 (native) -> vp9 (libvpx-vp9))
  Stream #0:4 -> #0:1 (mp2 (native) -> opus (libopus))
  Stream #0:6 -> #0:2 (dvb_teletext (libzvbi_teletextdec) -> webvtt (native))
Error while opening encoder for output stream #0:2 - maybe incorrect parameters such as bit_rate, rate, width or height
