的Ubuntu LTS 12.04，默認的ffmpeg/avconv。
我該如何解決這個問題？

這是[脫離堆棧溢出]（http://stackoverflow.com/faq#questions）。 *也許*它可以遷移到Ask Ubuntu或超級用戶... –

我找到了另一種解決方案。 ffmpeg應該從官方站點的鏈接下載到二進制版本（linux x64）。

Ubuntu版本在編解碼器時遇到問題。

我找到了解決辦法。需要安裝這些軟件包：sudo apt-get install libavcodec-extra-53 libavdevice-extra-53 libavfilter-extra-2 libavformat-extra-53 libavutil-extra-51 libpostproc-extra-52 libswscale-extra-2

我在Ubuntu 14.04中使用libvo_aacenc編解碼器代替aac編解碼器解決了這個問題。你可以改變你的命令，看起來像這樣：

avconv -i videoStream_1356794393712_805.flv -c:v mpeg4 -c:a libvo_aacenc videoStream_1356794393712_805.mp4
