对于多个输出使用相同的复滤波器

Question

你好，我正在尝试使用ffmpeg来直播流内容到youtube，以及输出一个mp4。问题是我有一个复杂的过滤器，不知道如何将它应用于两个输出。

这是代码

ffmpeg -re -i "https://mnmedias.api.telequebec.tv/m3u8/29880.m3u8" 
-i ./public/images/ACE.png 
-i ./public/images/logo2.jpg 
-filter_complex "[1]scale=40:40[ovrl1], [v0][ovrl1] overlay=580:10:enable='between(t,1,5)'[v1];[2]scale=40:40[ovrl2], [v1][ovrl2] overlay=580:10:enable='between(t,5,15)'[v2];[v2] drawtext=fontfile=fontfile=/System/Library/Fonts/Keyboard.ttf: \text='VideoGami':fontcolor=white: fontsize=24: x=(w-text_w)/2: y=(h-text_h)/1.05: enable='between(t,1,10)'" 
-acodec aac -vcodec libx264 -f flv "rtmp://a.rtmp.youtube.com/live2/moo" 
-acodec aac -vcodec libx264 trial.mp4

使用三通切割机。未经测试的示例：

ffmpeg -re -i "https://mnmedias.api.telequebec.tv/m3u8/29880.m3u8" -i ./public/images/ACE.png -i ./public/images/logo2.jpg -filter_complex "[1]scale=40:40[ovrl1], [0:v:6][ovrl1] overlay=580:10:enable='between(t,1,5)'[v1];[2]scale=40:40[ovrl2], [v1][ovrl2] overlay=580:10:enable='between(t,5,15)',drawtext=fontfile=fontfile=/System/Library/Fonts/Keyboard.ttf: \text='VideoGami':fontcolor=white: fontsize=24: x=(w-text_w)/2: y=(h-text_h)/1.05: enable='between(t,1,10)'[v]" -map "[v]" -map 0:a:6 -c:v libx264 -c:a aac -f tee "[f=flv]rtmp://a.rtmp.youtube.com/live2/moo|trial.mp4"
