我想在Ubuntu 12.04上使用ffmpeg在视频底部放一段简单的文字。我想这其中建议在几个地方:如何使用ffmpeg将文本添加到avi视频?
ffmpeg -i input.avi -vf drawtext="fontfile=/usr/share/fonts/truetype/ttf-dejavu/DejaVuSerif.ttf:text='Text to write':fontsize=20:fontcolor=black:x=100:y=100" output.avi
但每次我得到这个错误:

感谢你的帮助。
尝试添加'-acodec copy'。 – 2012-07-13 10:15:35
