ffmpeg - 使用 FFMPEG 的视频文本

Question

我正在尝试使用 ffmpeg 在视频上添加文本。我在 stackoverflow 上看到了很多帮助并关注了，但运气不好，我没能成功。

我已关注this thread .

这是我的命令

ffmpeg -i C:/source/TestScene.mov -vf drawtext="fontfile=c:/windows/fonts/arial.ttf: text='TestMessage': fontcolor=white: fontsize=24: box=1: <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="96f4f9eef5f9faf9e4abf4faf7f5fdd6a6b8a3" rel="noreferrer noopener nofollow">[email protected]</a>: boxborderw=5: x=(w-text_w)/2: y=(h-text_h)/2" -codec:a copy C:/source/TestScene_test.mov

这是我的错误回溯

F:\SW\ffmpeg\bin>ffmpeg -i C:/source/TestScene.mov -vf drawtext="fontfile=c:/windows/fonts/arial.ttf: text='TestMessage': fontcolor=white: fontsize=24: box=1: <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="71131e09121e1d1e034c131d10121a31415f44" rel="noreferrer noopener nofollow">[email protected]</a>: boxborderw=5: x=(w-text_w)/2: y=(h-text_h)/2" -codec:a copy C:/source/TestScene_test.mov

您必须转义字体路径并将其呈现为字符串:

fontfile='c\:\/windows\/fonts\/arial.ttf'
