Ffmpeg 使用concat的视频png覆盖问题

请允许我帮助理解为什么png徽标仅出现在concat结果的第一个视频上

谢谢

ffmpeg -f concat -safe 0 -y -i list.txt -i ../logo/logo.png -c:a copy -c:v libx264 -x264opts keyint=$50:min-keyint=$50:no-scenecut -bf 0 -r $25 -b:v 4800k -maxrate 9600k -bufsize 19200k -profile:v main -crf 22 -filter_complex "[0:v][1:v]overlay=main_w-overlay_w-10:10,scale=1920:1080,setsar=1" -t 370 1080set.mp4

我怀疑第二个和可能更多的输入具有不同属性的视频流，因此filtergraph会重新初始化，在这一点上，由于没有循环图像，因此没有图像帧可以覆盖

所以，循环图像

谢谢Gyan！我很想找出哪些是不同的属性
