如何使用ffmpeg和python添加文本到视频 [英] How to add text to a video with ffmpeg and python

问题描述

我一直在尝试使用ffmpeg将文本添加到avi，我似乎无法正确。

I've been trying to add text to an avi with ffmpeg and I can't seem to get it right.

请帮助：

import subprocess

ffmpeg = "C:\\ffmpeg_10_6_11.exe"
inVid = "C:\\test_in.avi"
outVid = "C:\\test_out.avi"

proc = subprocess.Popen(ffmpeg + " -i " + inVid + " -vf drawtext=fontfile='arial.ttf'|text='test' -y " + outVid , shell=True, stderr=subprocess.PIPE)
proc.wait()
print proc.stderr.read()

推荐答案

在指定drawtext的参数时，冒号：和反斜杠\具有特殊的含义。那么你可以做的是通过将：转换为\：和\转换为\\来转义它们。
此外，您可以使用单引号将路径添加到字体文件中，路径中包含空格。

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.

所以你将有

ffmpeg -i C:\Test\rec\vid_1321909320.avi -vf drawtext=fontfile='C\:\\Windows\\Fonts\\arial.ttf':text=test vid_1321909320.flv
