Hi I am rendering video with filters and adding audio at the end. But while running it is taking a long time and rendering continuously. Can anyone help me where I am wrong? below is the command

 ffmpeg -i test.png -i test.mp4 -i test.mp3  -y -filter_complex "[1:v]scale=1422:800[scale1],[scale1]rotate=0:c=black@0:ow=rotw(0):oh=roth(0)[rotate0],[0:v][rotate0]overlay=258.04:107.71[mediaoverlayout0],color=black@0:451x137[c1],[c1]setsar=1,drawtext=fontfile='/Windows/fonts/Peddana-Regular.ttf':text='ADITYA':fontsize=121.199:fontcolor=#1e8bc3:line_spacing=16.91,rotate=0:ow=rotw(0):oh=roth(0):c=black@0[rottext1],[mediaoverlayout0][rottext1]overlay=x=544.63:y=263.076[out]" -vcodec libx264 -map "[out]" -map 2:a -preset veryfast -c:a copy -pix_fmt yuv420p op.mp4 

推荐答案

添加-最短输出选项，因为 color = black @ 0:451x137 没有结尾时间，因此会无限期编码.

Add the -shortest output option because color=black@0:451x137 does not have an end time and therefore encodes indefinitely.

我猜您正在尝试在文本后面制作一个透明框.如果这是您要尝试的方法，请在drawtext中使用各种 box 选项.

I'm guessing you're trying to make a transparent box behind the text. If that's what you are trying to do then use the various box options in drawtext instead.

此外，您正在使用值为0的旋转过滤器.由于它们什么都不做，您可以忽略它们.

Also, you are using the rotate filter with a value of 0. You could just omit them since they are doing nothing.
