concat过滤器抱怨两个视频的分辨率不匹配。将其中一个调整为另一个的大小 下面，我重新缩放并将介绍填充到主视频的大小 ffmpeg-IC:\Temp\intro.mp4-IC:\Temp\main.mp4-filter_complex[0:v:0]比例=640:640:force_original_aspect_ratio=减小，pad=640:640:-1:-1，setsar=1[v0]；[v0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]-map[outv]-map[outa]-vsync vfr C:\Temp\output.mp4
由于concat过滤器最近发生了变化，因此在连接具有不同帧速率的剪辑时，建议使用-vsync vfr。非常感谢。现在它抱怨为输出流0:0缓冲的数据包太多。再次感谢您的帮助。这一次，它说没有输出焊盘可以关联到链接标签“main”。初始化复杂筛选器时出错。原始答案的argumentShare日志无效-带有缓冲数据包警告的日志工作正常。你能在回答中再解释一下吗？我的意思是，语法在我看来非常复杂，我不知道如何为我的其他视频量身定做。缩放和填充的前两个参数是主视频的宽度和高度。休息吧，你可以保持不变。
