【问题描述】：
我正在尝试使用 ffmpeg 在视频上添加文本。我在stackoverflow中看到了很多帮助并遵循了，但运气不好我无法成功。
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: boxcolor=black@0.5: 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: boxcolor=black@0.5: boxborderw=5: x=(w-text_w)/2: y=(h-text_h)/2" -codec:a copy C:/source/TestScene_test.mov
