提问by falek.marcin
I've try to add simple text on top of video with FFmpeg using drawtextparameter. Every time i'm going to do this, error is returned:
我尝试使用drawtext参数在带有 FFmpeg 的视频顶部添加简单的文本。每次我要这样做时，都会返回错误：
Could not load fontface from file 'arial.ttf': cannot open resource
无法从文件“arial.ttf”加载字体：无法打开资源
To indicate the location of the font I used the following methods:
为了指示字体的位置，我使用了以下方法：
ffmpeg -i C:\Test\rec\vid_1321909320.avi -vf drawtext=fontfile=arial.ttf:text=test -sameq vid_1321909320.flv
ffmpeg -i C:\Test\rec\vid_1321909320.avi -vf drawtext=fontfile=C:\Windows\Fonts\arial.ttf:text=test -sameq vid_1321909320.flv
All have failed. Does anyone have experience with adding text using ffmpeg?
都失败了。有没有人有使用 ffmpeg 添加文本的经验？

You cannot have a colon in the path to your font file as the colon acts as a key sepperator in ffmpeg. I had the same problem.
字体文件的路径中不能有冒号，因为冒号在 ffmpeg 中充当关键分隔符。我有同样的问题。
try:
尝试：
ffmpeg -i C:\Test\rec\vid_1321909320.avi -vf drawtext=fontfile=/Windows/Fonts/arial.ttf:text=test -sameq vid_1321909320.flv

A colon ":" and a backslash "\" have special meaning when specifying the parameters for drawtext. So what you can do is to escape them by converting ":" to "\:" and "\" to "\\". Also you can enclose the path to your font file in single quotes incase the path contains spaces.
在指定 drawtext 的参数时，冒号“:”和反斜杠“\”具有特殊含义。所以你可以做的是通过将“:”转换为“\:”并将“\”转换为“\\”来转义它们。您也可以将字体文件的路径用单引号括起来，以防路径包含空格。
So you will have
所以你会有
ffmpeg -i C:\Test\rec\vid_1321909320.avi -vf drawtext=fontfile='C\:\Windows\Fonts\arial.ttf':text=test vid_1321909320.flv

I was also having trouble with ffmpeg recognizing Windows paths. I finally just put the font Arial.ttf in the same folder as the input file and it worked.
我也遇到了 ffmpeg 识别 Windows 路径的问题。我最后只是将字体 Arial.ttf 放在与输入文件相同的文件夹中并且它起作用了。
