ffmpeg给出文本未找到错误

Question

arial.ttf 存在于 C:\Windows\Fonts 文件夹中。运行

ffmpeg.exe -i D:\imagesequence\test.mov -vf drawtext="arial.ttf=':text='TEST'"D:\imagesequence\testo.mov

或者

ffmpeg.exe -i D:\imagesequence\test.%04d.jpg -vf drawtext="arial.ttf=':text='TEST'"D:\imagesequence\testo.mov

结果是

ffmpeg.exe -i D:\imagesequence\test.%04d.jpg -vf drawtext=fontf
ile="arial.ttf=':text='TEST'" D:\imagesequence\testo.mov

LordNeckbeard 是正确的，您需要使用“fontfile”指定您尝试使用的字体的完整路径。此外，如果您的输入和输出文件位于同一目录中，则无需指定它们各自的目录(省去了命令行的麻烦)。在您的情况下，这应该有效:

ffmpeg.exe -i test.mov -vf drawtext=fontfile=/Windows/Fonts/arial.ttf:text="TEST" testo.mov
